Costs of Charging a Tesla at Home: With or Without Solar

One of the most common questions new Tesla owners ask is: how much does it cost to charge at home? The answer depends heavily on whether you’re pulling power from the grid or offsetting your electricity use with solar panels. In this article, we’ll break down the true costs of charging a Tesla at home, compare the difference between grid electricity and solar, and explain the long-term financial impact of both options.

How Weather & Seasons Affect Solar Energy Output

Why Seasonality Matters for Solar

Solar panels are most effective when they receive consistent, direct sunlight. But across the year, factors like temperature, cloud cover, and day length vary significantly — and so does solar output. Whether you’re installing a system or optimizing an existing one, understanding seasonal and weather-related changes is key to accurate energy forecasting and return on investment.

1. How Solar Panels Work with Sunlight

Solar panels convert solar irradiance (sunlight energy per square meter) into electricity using photovoltaic (PV) cells. The more irradiance, the more energy. But not all sunlight is equal:

• Direct sunlight leads to peak performance.

• Diffuse sunlight (through clouds or haze) still generates power, but less efficiently.

Key Stat:

On a clear day, panels can generate up to 1,000 W/m², while overcast conditions may drop output to 100–300 W/m². (Source: NREL)

2. Seasonal Changes: What to Expect

🌞 Summer

• Longest daylight hours.

• High solar irradiance, but excessive heat can reduce efficiency (~0.5% loss per °C above 25°C).

• Best total daily output.

Example:

A 6kW system in Los Angeles can produce ~900 kWh/month in July compared to ~450 kWh/month in December. (Source: PVWatts Calculator)

❄️ Winter

• Shorter days.

• Lower sun angle and potential snow coverage.

• Colder temps can improve panel efficiency — but less total sunlight.

🌱 Spring/Fall

• Moderate temperatures enhance efficiency.

• Decent sun angle and longer days.

• Often the most consistent production months.

3. Weather Impacts on Solar Energy

☁️ Clouds

• Can reduce production by 10–25%, or more in dense overcast.

• Panels still produce power from diffuse light.

🌧️ Rain

• Lowers output temporarily.

• Benefits: cleans dirt off panels, maintains efficiency.

❄️ Snow

• Blocks production when covering panels.

• Can reflect sunlight when partially melted, sometimes increasing output briefly.

• Angled panels help snow slide off quickly.

Data Point:

A light snow cover can reduce output by up to 60%, while heavy snow may cut it entirely until cleared. (Source: University of Minnesota Solar Suitability Analysis)

🔥 Heatwaves

• High ambient temperatures can reduce output.

• Panel performance drops ~0.4%–0.5% per °C above 25°C.

• Ventilation and light-colored mounting surfaces help reduce thermal buildup.

4. Geographic Examples: U.S. Solar Production Variance

City	Avg. Annual Solar Production (kWh/kW)	Peak Month	Lowest Month
Phoenix, AZ	1,800–2,000	June	December
Miami, FL	1,600–1,800	May	January
Chicago, IL	1,300–1,500	July	December
Seattle, WA	1,000–1,200	July	December

5. How to Optimize Solar Year-Round

• Adjust tilt angles seasonally if using adjustable mounts.

  • Winter: tilt = latitude + 15°

  • Summer: tilt = latitude – 15°

• Regular cleaning improves efficiency by 5–10%.

• Install monitoring systems to track real-time performance.

• Use battery storage: Store excess in high-output months for later use.

6. Use Solar Mapping Tools for Better Forecasting

✅ Top Tools:

• NREL PVWatts Calculator – Estimates production by month.

• Google Project Sunroof – Maps solar potential based on roof geometry.

• Solar Energy Maps (like yours) – Offer irradiance overlays, seasonal comparisons, and historical data.

Tip:
Overlay your solar production map with historical cloud cover and temperature datasets for deeper insights.

Conclusion

Solar panels produce energy in all seasons, but the output varies based on weather and geography. Understanding these patterns — and using data to forecast them — helps system owners maximize efficiency and ROI year-round. By leveraging smart tools and adjusting system settings, homeowners and businesses can harness solar energy even through winter gloom or summer heat.

Types of Solar Panels for Homes: A Complete Guide

As the demand for renewable energy grows, solar panels have become a popular choice for homeowners seeking to reduce their electricity costs and environmental impact. In this guide, we’ll explore the different types of solar panels available for homes, their benefits, and the trends surrounding their adoption and market share.

What Are Solar Panels?

Solar panels are devices that capture sunlight and convert it into usable electricity. These panels are typically made up of photovoltaic (PV) cells that work together to generate solar electricity for your home. Whether you’re interested in solar power for the home or solar energy panels for homes, understanding the different types of solar panels is the first step.

Solar panels come in various types based on the technology used to convert solar energy. Choosing the right type for your home depends on factors like efficiency, cost, space, and aesthetic preferences.

Types of Solar Panels for Homes

There are three main types of solar panels to consider for your home:

1. Monocrystalline Solar Panels

Monocrystalline solar panels are made from a single crystal structure, making them highly efficient and durable. They are recognized for their sleek, black appearance, as the cells are cut from cylindrical silicon ingots.

• Efficiency: These panels typically have an efficiency rate of 15% to 20%, meaning they convert 15% to 20% of the sunlight they capture into usable electricity. They are the most efficient panel type, making them ideal for homeowners with limited roof space who need maximum power generation.

• Adoption & Market Share: Monocrystalline panels gained widespread popularity in the early 2000s due to their superior efficiency compared to earlier technologies. As of recent years, monocrystalline solar panels represent about 50% of the global solar panel market. They are the most widely adopted option, especially for residential installations in developed countries.

• Cost: In regions like California, which has high labor costs and robust state incentives, the cost of installing monocrystalline panels ranges from $14,000 to $18,000 for a typical 5 kW system. Prices may be a bit lower in states like Texas, where costs average $12,500 to $16,000, thanks to lower installation fees and fewer state-specific rebates.

2. Polycrystalline Solar Panels

Polycrystalline solar panels are made by melting silicon and pouring it into molds to create multiple crystals. These panels have a slightly less efficient performance but come at a lower cost.

• Efficiency: Polycrystalline panels have an efficiency rate of about 13% to 16%, slightly lower than monocrystalline panels.

• Adoption & Market Share: Polycrystalline panels became popular in the mid-2000s and made solar energy more affordable for homeowners. They still account for about 30% to 35% of the global solar market as of recent data. Their lower cost makes them a preferred option for residential installations in regions where upfront costs are a significant consideration.

• Cost: The cost for a 5 kW polycrystalline system typically ranges between $12,500 and $16,000 in regions like Florida and Texas, where solar prices are more competitive. In contrast, the same system could cost $13,000 to $18,000 in New York, where labor costs and permitting fees are higher.

3. Thin-Film Solar Panels

Thin-film solar panels are created by depositing photovoltaic material onto a substrate like glass, plastic, or metal. These panels are lightweight, flexible, and can be integrated into a variety of surfaces, including windows and roofs.

• Efficiency: Thin-film panels are the least efficient, with an efficiency rate of about 10% to 12%. While they require more space to produce the same amount of electricity as other types, their versatility makes them suitable for different applications.

• Adoption & Market Share: Although thin-film technology represented a significant portion of the solar market in the 1990s and early 2000s, it has seen a decline in residential adoption. As of now, thin-film panels represent about 10% to 15% of the global solar market, with their primary use being in large-scale commercial projects and utility-scale solar farms.

• Cost: Thin-film panels are generally the cheapest to manufacture, which makes them an affordable option for large-scale projects. However, due to their lower efficiency, they are less common in residential homes. Installation for a 5 kW system using thin-film panels could range from $10,000 to $15,000, depending on local labor costs and solar availability.

Regional Breakdown of Solar Panel Costs

When choosing solar panels for your home, it’s important to consider how installation costs vary by region. The price of solar panel systems can fluctuate based on factors like local labor rates, sunlight availability, and state-specific incentives.

California: The Solar Capital

• Cost: In California, one of the leading states for solar adoption, the price for solar installation can range from $14,000 to $18,000 for a 5 kW system. This includes state incentives like the California Solar Initiative and net metering, which allows homeowners to reduce their energy bills by selling excess power back to the grid.

• Why It’s Popular: California’s abundant sunlight, high electricity costs, and strong state incentives make it an attractive option for solar energy.

Texas: A Growing Solar Market

• Cost: Texas, with its abundant sunlight, offers installation costs ranging from $12,500 to $16,000 for a 5 kW system. The cost tends to be lower due to less expensive labor and fewer state-specific incentives.

New York: High Costs with Significant Incentives

• Cost: In New York, the installation costs for a 5 kW system can range from $15,000 to $20,000 due to higher labor costs and permitting fees. However, New York offers a range of incentives, including the NY-Sun Initiative and Property Tax Exemptions, making solar more affordable for residents.

• Why It’s Popular: High electricity rates make solar power a cost-effective solution for New York homeowners, even with higher initial costs.

Florida: Sunshine State with Competitive Pricing

• Cost: In Florida, which enjoys abundant sunlight year-round, the average cost for a 5 kW system ranges from $12,500 to $16,000 after applying state rebates and federal tax credits.

• Why It’s Popular: The combination of strong sunlight and competitive prices make Florida an ideal location for solar installations.

Benefits of Solar Panels for Homes

Solar energy for homes offers a range of benefits, including:

• Lower Energy Bills: By switching to solar power for the home, you can significantly reduce your monthly electricity costs. Homeowners who install solar panels can save an average of $10,000 to $30,000 over 20 years on their energy bills, depending on location, energy usage, and system size.

• Eco-Friendly: Solar energy is a clean, renewable source of power that helps reduce your carbon footprint. Each kilowatt-hour (kWh) of solar electricity you generate prevents about 0.92 kg of CO2 emissions.

• Increased Property Value: Homes with solar energy panels for homes are often valued higher. On average, homes with solar panels have a 4% to 6% higher resale value than homes without them.

• Energy Independence: Solar electricity installation gives you greater control over your energy usage and reduces dependence on the grid. For homeowners who install battery storage systems, such as Tesla Powerwalls, they can store excess energy generated during the day for use at night or during power outages.

Solar Power Roofs: An Innovative Solution

Solar power roofs integrate solar panels directly into the roofing material, offering a seamless look while generating solar electricity for homes. This innovative solution not only reduces the visual impact of traditional solar panels but also maximizes roof space.

Solar roofs are typically made using solar shingles or solar tiles, which are designed to look like traditional roofing materials while also generating power. This option is ideal for homeowners who want an aesthetic solution while reaping the benefits of solar energy.

Conclusion: Choosing the Right Solar Panels for Your Home

With several types of solar panels available, it’s important to consider your home’s energy needs, roof space, and budget when selecting a system. Whether you’re looking for solar electric panels for homes or solar and energy solutions, investing in solar panels can save you money in the long run while helping you contribute to a greener planet.

Recent trends indicate that monocrystalline panels will continue to dominate the residential market due to their higher efficiency, though polycrystalline panels remain a popular choice for homeowners on a budget. Thin-film technology, while less efficient, may see a resurgence in large-scale projects as manufacturers continue to innovate in making them more affordable and efficient.

Why is Solar Energy Renewable?

When it comes to solar energy companies, there is a lot to discuss. Where do they source their materials, who becomes a solar installer, and why is solar energy important. . . The list of questions can go on and on. Still, one of the more interesting questions to ask is, “Why is solar energy renewable?” 

Which States Have The Most & Least Solar Schools?

Map of Solar Schools

How Can Solar Energy Help in Reducing Carbon Prints?

The atmosphere has suffered a great blow since humans began cutting trees recklessly and using sources of energy that pollute the environment. The effects of these practices are evident in how the weather patterns are changing unfavorably. However, all is not lost. Whatever is left of the earth can still be salvaged and the adverse effects can be reversed with the help of solar energy.

Choosing the Best Battery for Solar Storage in 2021

 

Investing in solar energy is often an intelligent decision, depending on where you live. The power generated from solar panels on your home could help you save money long-term, and it also takes a step toward improving your home’s resiliency to natural disasters like earthquakes or wildfires. In fact, increasing your home’s electrical independence can even help prevent future grid disasters.

Why Don’t We Put Solar Panels Everywhere?

Once a novelty associated with mad scientists and eccentric visionaries, solar panels eventually became a mainstream technology in the early-21st century. They went from being a rare sight to frequently spotted on rooftops all around town. That transition is owed mostly to the increasing affordability of solar panel installations and a growing desire among the public to support green energy solutions.

Embrace the Future when you Install Solar Panels

Looking for a better way to power your house? Go solar. Rooftop solar panels convert sunlight into electricity for your home, eliminating or drastically reducing your monthly electric bill. Solar panels are not the right fit for everyone, but for many, they’re a great green way to reduce your carbon footprint.

Solar panels are an investment, but you can recoup the initial cost – and more – in the years to come.

Going off the energy grid is becoming an increasingly popular option, with about 600,000 U.S. homeowners enjoying solar panel energy, according to the Solar Energy Industries Association (SEIA), and many more solar systems operating worldwide.

You can feel good about helping this planet move toward sustainable energy sources. Nonrenewable energy-produced electricity sources pollute the earth, but solar energy ensures clean renewable energy.

Because solar panels have become more popular and technologically advanced, the manufacturing price has dropped, so it’s not just for wealthy homeowners anymore.

Is solar energy the right choice for you? Consider things like your home’s location, how long you’ll remain in your home, whether you want to own or lease your panels, your present electric bill, and financial incentives that may be available.

What are Solar Panels and How Do They Work?

Solar panels are made from tempered glass. They’re installed on a rack system on your roof and an inverter system generates electricity for your home, potentially eliminating dependence on your local electricity company. Your system may include a bi-directional meter that measures the power produced and the amount you use. You may be able to sell any excess power if your local electric company participates.

The monitoring system lets you see the amount of energy your panels produce daily (and over time) and also notifies you if there’s a problem with a panel.

Pros of Solar Panels

There are a plethora of reasons to go solar, including reducing your carbon footprint and saving money. Many countries rely on fossil-fuel-produced energy, including coal and fuel. Producing electricity from those fuels is expensive. So is the cost of building new nuclear-powered plants. Those increasing costs are passed on to you.

Solar Saves Money

If you dread paying your massive monthly electricity bill, solar is definitely an option. Solar could drastically reduce your dependency on your present electric supplier. Installing a solar-powered electric system now could mean your future electric bills could shrink, especially once you’re no longer paying for the cost of the panel system.

You may even be able to make some money from your solar panels. Check with your government and your electric company to see if they have a buy-back energy metering program and solar renewable energy credits. These kinds of programs let you bank money (or receive credit on your electric bill) while your system generates electricity. You could be paid for extra electricity your panels produce.

Low Maintenance Costs

Solar rooftop panels require little maintenance, especially if they’re tilted. They may need a light cleaning every few months to remove dirt, leaves, and other debris using a leaf blower or garden hose, and you may also need to clear panels after a heavy snowfall. Panels installed on the ground are even easier to keep clean because they’re on your level.

Solar panels are sturdy so they can weather storms and even hail, but you’ll still want to have a warranty or homeowner’s insurance in case you need to repair or replace any storm-damaged panels.

Reduce your Carbon Footprint

Solar energy is clean and renewable, the perfect way to reduce the atmosphere-damaging carbon dioxide emissions coming from your property. Producing solar electricity doesn’t create pollutants and is even more earth-friendly than nuclear energy.

Your choice to transition your home to solar energy also helps lessen the need for – and the dependency on – fossil fuels.

Solar Considerations

There are some things to consider before you jump on the solar bandwagon. For instance, how long do you plan to stay in your home? How long will the panels last, and how much should you budget for buying or leasing?

Solar energy isn’t a get-reimbursed-quickly system. Instead, it’s a long-term investment so consider how long you’ll live in your home. It could take seven or more years for you to recoup the purchase cost through energy savings.

Another thing to consider is the condition of your present roof. You’ll have to remove the panels and put them back when you replace shingles on your roof. Therefore, if you’re considering getting panels, take a good look at your roof. If it has seen better days, you may want to replace it before you install solar panels.

How Long do Panels Last?

Panels are made to give you years of dependable electric service and can last from 25 to 35 years. You can enjoy energy-saving benefits for quite a while before you need to replace them.

Installation costs

Look for a professional company to install your panels. The cost of both panels and installation vary according to your system, region, and the location of the panels (on a roof or on the ground).

Can Your Roof Hold Solar Panels?

Before signing up, do some homework on your own roof’s age and materials. Installing solar panels consists of mounting a connected racking system directly onto your roof, and not all roofs are suitable. Roofs on homes that are historical (or are older), those with slate or cedar tile roofs, or homes with skylights or roof decks are difficult to fit with racking systems. There could also be concerns with roof leaks because the racking is screwed directly onto your roof.

If your roof isn’t a candidate for panels but you have the room in your yard, you can have panels installed on the ground. If neither of those locations is an option, you can research whether there’s a local community “solar garden” that you can participate in.

Climate and Weather

The amount of sun that hits your roof and its orientation to the sun can impact how much energy your solar panel system generates each day. The more sun (and less shade) your roof has, the more energy those panels can produce. This is great news for homeowners in high-sun regions.

Solar panels can lose a small amount of their efficiency in climates whose heat rises above about 90 degrees, though. You can keep track of how weather affects your panels through the monitoring panel.

Don’t Forget Insurance

Installing solar panels on your roof may increase – or decrease – the cost of your homeowner’s insurance. This is something to discuss with your insurance company before you have panels secured onto your roof.

Cost of Solar Panels

The cost of installing solar panels will depend upon the location, the number of panels, the size of the system, and other factors. Remember that the more electricity you normally use, the sooner you can recoup your investment by going solar. If you know your current energy usage, you can calculate how much you’ll need to budget monthly for solar panels.

Leasing vs. Buying

There are a couple of ways to start taking advantage of this earth-friendly “off the grid” energy source: you can buy your solar panel system outright or you can lease it. Both ways have pros and cons.

Why Lease?

Some homeowners choose to lease their solar electric systems. Leasing lets you go solar without the big up-front costs. If you don’t have thousands of dollars for a down payment, you can lease while still helping the environment and lowering your electrical bills.

Leasing lets you install solar panels and start saving right away. You may have numerous finance options when leasing. For instance, you can pay the leasing company for the equipment and use as much energy as you want, or you can pay the solar company based on the monthly kilowatt-hours used. Some leasing companies also offer the option of buying the panel system at the end of your lease. Financing and leasing options will vary depending on where you live.

Another advantage of leasing solar panels: you won’t have to fix them if there’s an issue. The company you lease them from should do the maintenance and repairs, depending on the terms of your lease.

Down Sides to Leasing

While there are definite pluses to leasing your solar electric system, there also are some drawbacks to ponder.

Solar leasing contracts can last up to 20 years or longer. Also, you probably won’t get any tax benefits or rebates (if wherever you reside offers those) by leasing versus owning. In addition, you’re locked into having equipment on your roof that belongs to a company, not you.

All in all, you still should save money by leasing while doing your part for the planet.

Advantages of Owning

There are definite advantages to owning your solar panel system rather than leasing. One of the biggest pluses is that many governments or electric companies offer incentives for installing this green energy source.

Owning your own system also means you’re not tied to a year-long contract. You own the panels instead of someone else owning the panels. Also, if you decide to sell your home, having a solar energy system can be a great selling point and increase the home’s value.

Disadvantages of Owning

There are some negatives to buying your own system. The most obvious disadvantage is the up-front investment required. If you buy, it may take some years before you break even, depending on how much your electricity bill is now. If you normally don’t have a hefty bill, it will take longer to recoup your costs. If your normal electricity bills are high it could be less time, depending on the cost of your system.

If you own your solar panels and monitoring system, you’ll be responsible for maintaining and repairing (or replacing) when parts fail or need work.

Solar is the Future

Installing solar panels is an enticing, Earth-friendly option, but it’s wise to consider all factors before taking the plunge. Solar energy system installation and material costs are decreasing as technology and production methods improve, so it’s becoming an appealing alternative to expensive electricity. It is definitely an investment, but worth adding value to your home as you help make this a greener planet.

How Long Do Solar Panels Last?

Now that we have discussed the benefits and overall life of solar panels, it is time to explain the process of their disposal. This page describes not only how long they last, but also how you can save them from decay.
 
No matter what level of understanding you have, it is important to remember that there are many things that can affect the average life of your solar panels. Anyone new to solar energy does not have to know everything. Solar can teach you everything you need to know about how a solar system works, how to connect it to the public grid, and how much it costs. Contact us to learn more about our repair and maintenance services for solar panels and other related issues.


 
Assuming that the end of the life of a solar panel means that it stops producing electricity, how long will the life of your solar panel be? The industry term "solar panel lifetime" is a degradation rate that describes the performance that a solar panel experiences over time.
 
At this point, it is fair to estimate that your solar panel will still produce energy after the warranty expires. If you have a 0.5% deterioration, the solar panels in your system should continue to run for a long time, which means that you should still operate your solar system even after the warranty has expired. Also, here are some tips to follow to ensure you keep solar panels for the longest period of time.
 
If you understand how long you can expect to benefit your solar panels, you will put your initial investment in context. Typically, guarantees guarantee that your panels will work for the 25 years they are considered efficient, but in reality, they can last quite long. Depending on the manufacturer, the performance of the solar panels cannot be guaranteed and it is very possible that the modules will produce electricity for more than 25-30 years. The fact that some panels, such as those with a 25-year warranty and those that last 25 + years, can give you an idea of how much solar power you should expect over time from a solar-powered system.
 
There is already plenty of evidence that solar panels can last up to 30 years, but real-world experiments will tell you more about the long-term impact of solar energy on your home and energy consumption.
 
There is already plenty of evidence that solar panels can last up to 30 years, but real-world experiments will tell you more about the long-term impact of solar energy on your home's energy consumption. If you ask yourself how long a solar panel lasts in the real world, you ask yourself: "How is this possible"?
 
In 2012, a study by the National Renewable Energy Laboratory (NREL) found that the average life of a solar panel is between 20 and 30 years. Let's take a moment to explore why solar cells degrade over their lifetime and what impact solar energy has on your home's energy consumption. The Solar Energy Industries Association is a group of companies responsible for the production of more than 80 percent of the world's solar panels, so let's look at their research and learn more about the long-term impact of these panels on energy consumption.
 
Generally, solar panels will last between 25 and 30 years, but a number of factors complicate this estimate. The question arises: What makes a solar module last so long and why does it last so long? The expected life of a panel varies from year to year, and the estimate of the average life of each panel changes.
 
Solar panels are the power plant of the future, and like any other device you use in your home, you want to know how long it will last. As a homeowner, you can take steps to extend the life of your solar panels. Let's take a closer look at how long solar panels last on your roof so you're prepared and know how best to keep them waiting as long as possible.
 
If you have considered a major investment like this, it is also an obvious concern that you can expect it to last until the end: How long do solar panels last? When we consider a large investment as a home plan or as an investment in a new home, the question of how long we can expect our solar panel to last is always a direct concern for us, especially when we consider large investments like this. 

Does Your Roof Need to Face South for Solar?

East- and West-Facing Roofs are Great for Solar

We all know south-facing roofs are the best option for installing solar, but what if your roof does not face south? What if the south side of your roof is shaded or at a bad angle?

Don’t worry. A southern orientation is not crucial for a solar installation. East- or west-facing roofs are also great candidates for solar.

Even though the sun shines from the south, the east and west sides of a roof are exposed to significant amounts of sunlight throughout the day. In fact, east- and west-facing solar panels can produce 80% as much electricity as south-facing solar panels.

What this means is that with a small increase in the number of solar panels on your roof, your east- or west-facing solar panels can produce just as much electricity as a south-facing solar panels. 

When is East-Facing Solar a Better Option?

The best strategy for solar production is to produce electricity when you need it. This means that sometimes a south-facing roof is not the best option for solar panels. This can be the case for households or businesses that see high electricity use early in the day.

As businesses or households start flipping switches to turn on lights and equipment and start powering up computers and other machinery, their energy consumption can quickly ramp up. This is the time when solar could help cover their energy demands.

For these consumers, early-morning energy production from the east or southeast-facing solar panels is a good option. East-facing solar panels can take advantage of the early-morning sun and start producing electricity earlier than south-facing solar panels. 

When is West-Facing Solar a Better Option?

As stated above, the best strategy for solar is to produce energy when you need it most. For many households, their highest energy demands come in the evening. As families get home from work and school, they start turning on lights, televisions, microwaves, washers, and dryers, and their energy consumption skyrockets.

To meet these late-evening energy demands, it can sometimes be a good strategy to have solar panels that face west or southwest to take advantage of the evening sun.

Designing your solar system to produce electricity in the evening can also help avoid Time-Of-Use (TOU) utility rates. TOU rates charge more for energy used during peak demand periods, often in the evening when households are ramping up their energy usage.

With west and southwest-facing solar installations, solar panels can produce electricity when TOU rates are highest and help reduce energy bills.

Energy-Saving Apps and Gadgets Perfect for Holiday Gifts

Not all gifts have to be power-guzzling game consoles, They do send quite the mixed message. On the one hand, you care about saving energy and saving the planet. On the other hand, you consume industrial-level watts per hour blasting fake enemies in 4K splendor. Something seems a little off about that.

Perhaps this is the year we all do a little better at giving gifts that are consistent with our values. If you are a low-calorie guru, you wouldn’t give everyone on your list a box of chocolates. You want to give people things they will enjoy, but that also reflects who you are as the giver.

Sometimes, your gift is a statement of intent or even a call for a certain kind of action. Rather than another video game, you could give your child a basketball and membership at the local Y. You might give a less athletic child nice chess set to encourage their analytical thinking. So what do you give your friends and family to help them save energy, and show your commitment to conservation? Here are a few suggestions:

An Electric Vehicle

Why not go big? Get your family the gift of green. Put a new electric car in the garage and provide an app or website for all the drivers so they can easily search for “charging stations near me”. Don’t just talk about how bad fossil fuels are. Take a big step away from using them. Breaking dependency on fossil fuels starts at home.

While you’re at it, go big and go home. Add solar to your home and get completely off the grid. If you are the kind of person who likes to keep up with all the solar locations worldwide, why not become a solar location? Make your home the model of what you believe homes should be. Why have a white Christmas when you can have a green one instead?

Lights That Turn Themselves Off

A great energy-saving gift is a motion sensor that turns off the lights when you leave the room. If you have kids, you know it is useless to keep telling them to turn the lights out when they leave a room. Come to think of it, the problem isn’t just the children. Perhaps there is something in human nature that causes us to leave the lights on even when we don’t need them.

With motion sensors, you don’t have to worry about it. You can set things up so that the lights always go off even if everyone forgets to check. You will save money from all the lights you are not burning. When you need light, go for energy-efficient bulbs. These are fun and inexpensive gifts that can save money and the planet.

Thermal Leak Detector

Do you know where your heat is leaking? It is almost certain that you have heat leaking somewhere in your home. Those leaks are costing you a ton of money. The problem is that it is almost impossible to know where the leaks are just by eyeballing it.

This is where a good thermal leak detector comes in. It is a handheld tool that reads the ambient temperature. From there, you can point at places you think heat and air might be escaping. The device indicates hot spots and cool spots. This allows you to seal those areas that are costing you money. With a device like this, you can use less heat in the winter and less air in the summer. Save money year-round.

While you’re at it, you might want to pick up one of those smart thermostats that only heat the areas of the home that are needed at any given time. You can control the heating and cool it from your smartphone. Better yet, you can let the smart unit make those decisions. Again, the end result is that you save money.

There are a lot of ways to save money, and just as many ways to give the gift of green. You can go big and go home by investing in an electric vehicle and powering your home with the sun. You can go for stocking stuffers like motion sensors and energy-efficient bulbs. And you can use gadgets to find those expensive energy leaks and allow your smart gadgets to be the brains of the whole energy-saving operation. 

Are Solar Panels Worth it?

One of the most interesting energy technologies at this time is solar power. Yes, wind energy and thermal power are both experiencing a surge in interest, but it feels like solar power will be the strongest contender on the global market. There are many reasons for this, but one overpowers the rest.

That reason is the continually decreasing cost of the product. It was not too long ago that people’s main argument against solar energy systems was the exuberant cost. But now, solar contractors around the world are offering 0% financing and other incentives to entice new users. Similarly, governments and energy regulators are also offering buyback programs for excess energy production from residential and commercial systems.

These two trends are causing many people to rethink the pivotal question, “Are solar panels worth it?” This question demands a lot of attention in the current climate, and to discuss it from a purely monetary perspective seems to be an injustice. There are many other avenues worth referencing in regards to solar power, such as the environmental impact and longevity.

The environmental impact is perhaps of the greatest concern. Solar energy is capable of producing renewable energy, and the production of the materials is not terribly detrimental either. As well, when you compare the environmental impact of producing solar panels to that of running a coal plant, there is quite a stark difference.

Additionally, the renewable aspect of solar energy is an essential distinction. Indeed, after a couple of decades, there is a small amount of energy loss, but this negligible problem has almost no bearing on the renewable energy facet. Even with a reduction in power, once enough systems are contributing to the production of solar energy, there will be enough power for all people to use.

As well, the longevity of the product is worth its own weight in the debate. Solar panels typically last 25 years or so, and in that time, they only require minimal upkeep, such as cleaning and regular wiping. Furthermore, replacing parts of the system is relatively easy and often is as simple as swapping out a defective panel or inverter for a new model.

In conclusion, you may wish to imagine the following future. In this theoretical time, everyone has solar systems in their home, and they collectively contribute to the energy needs of the rest of society. Energy consumption is no longer a market, but instead a right available for all humanity. Furthermore, the construction of homes includes solar panels in the planning stage, much like a roof or garage.

In this future, people work together to provide a cleaner and brighter future for the next generation because they understand the value of future generations. This future is possible, and it can even be probable with the adoption of solar panels as a path forward. Ultimately, the question of whether or not solar panels are worth it is equivalent to asking whether or not our children’s children are worth it, and the answer to that question should be easy for you to answer.

How to Choose a Solar Power Company

Most scientists and climate activists agree on one thing more than any other: Solar power is the way of the future. Millions of people envision a world where burning coal and building nuclear facilities is a thing of the past. Instead, humanity will harness the power of the sun to power our everyday lives. The sun has more than enough energy to offer us. Until which point it burns out, the sun could provide enough electricity for every single person on earth a million times over, if only it was harnessed and converted correctly.

There have been a lot of significant advances over the past few years with solar panels and different kits that people have installed in their homes. More people than ever are getting their energy through solar means, and some people are even getting so much of it that they end up profiting when selling power back to the grid. Though, to be clear, solar panels are products, so the system you get is only as good as the solar power company with which you choose to do business. So, how will you find the best one? Here are some things to keep in mind when you’re exploring your options for solar companies.

Tips for Choosing the Right Business for Your Solar Power Needs

Make Sure They Match Your Needs

The first tip here is to only go with a company that matches your needs. Some of those needs, which you need to consider, are expediency and pricing. To help you get a system installed much faster, and for a more affordable rate, you should consider looking locally. Not having to travel far to install your system means saving a ton on shipping costs and also getting it installed quicker. Though another thing of which you want to be aware here is the fact that not every system is one size fits all. You want a company that’s going to offer you a system that matches the exact requirements of your home. You want something that works well, not something that barely supplements your existing methods.

Find Professionals to Install the System

Another thing you’re looking for with a quality solar power company is the ability to install the system for you as a professional. If you were to study the topic a bit and have a relatively good understanding of electronics and carpentry, then you could undoubtedly install the panels yourself. Though, by that same token, most people could study and train and build their own houses themselves. Who has the time or energy or expertise to do that, however? This problem is why it’s so important that you shop only with a quality company that’s going to show up and professionally installs your system for you. This way, you know it’s going to work, above all.

Get an Estimate

The next thing you want to look for in the right company selling solar goods is their willingness to be upfront with you about how much things are going to cost. Some sites will refer to this as a free quote or an estimate. Whatever name they give it, it’s important that you receive an estimate. This result means that the company is looking at the size of your property, calculating your exact energy needs. Then they’re going to estimate the package you’re getting, the costs of installation, and give you a quote for how much you can expect to spend. This way is far better than merely having people spring surprise charges on you.

Check Out User Ratings

Lastly, you should make an effort to look at the ratings of the company you’re considering. The thing about online reviews is that you never know which can be trusted. However, if you visit various blogs and forums, you will find people giving their real opinions about real companies. This organic knowledge is what you want to have. For instance, find someone’s Facebook or blog in your immediate area who has solar power now and are thrilled with the package they received, and find out who they chose.

It’s easy to get solar power these days. There are all sorts of companies offering these services. Just make sure you use the tips above so that you can find the absolute best company with which to do business.

How Does Solar Power Work?

Throughout the entire universe, scientists agree that there is no better example of energy than nuclear fission. We don’t have to look farther than our own solar system’s sun to see this process in action. Every single second within the giant ball of burning gas that is our sun, 600 million tons of helium convert into hydrogen, which then converts 4 million tons of matter into pure energy. The energy generated remains at the core of the gas giant for 10,000 to 170,000 years. Needless to say, people for all of history have been looking for ways to copy this process for limitless energy on Earth.

To date, the best we have at mimicking the sun’s energy is actually to use the sun’s energy through solar power. Though it’s not quite as simple as holding an appliance under direct sunlight, the energy that the sun puts out isn’t just freeform energy we can use. It has to be absorbed and converted into usable electricity for appliances, lights, etc. How does that process work? Here is a quick rundown on how we harness the power of the sun and convert it into usable energy.

The Steps to Converting Sunlight into Energy

Photovoltaic Cells

The first step in this process is to absorb the sunlight through what are called photovoltaic cells. Most people know them merely as solar panels. These aren’t just pieces of glass that you hold under the sun. There is a lot of intricacy going on with these panels, which feature multiple layers of PV cells that have a photovoltaic effect and actually absorb the sun’s energy. It doesn’t absorb the light per se; it absorbs the UV rays, which act as energy when it hits the PV cells, and this works the best when it’s a direct line with the sun’s energy. The sun’s energy output remains relatively constant, so the effects of the power from the sun in this regard has much more to do with the quality and functionality of the PV cells set up to absorb that energy.

Solar Converters

So, with the right PV cells, solar power is ready to be used as electricity, right? There’s another step here not to overlook. Once we harness the power of the sun, we have to convert it into actual electricity for use. This typically happens once a solar inverter, as part of a solar panel system, converts the power from DC (direct current) electricity from the solar modules into AC (alternating current) electricity. This conversion means we can use the energy to charge up a series of batteries, which are wired throughout the home like basic electrical components, thus used to provide the electricity people use in their day to day lives. It has to be converted and stored before use.

Flowing Electricity

 After this point, the electricity is flowing through the home, but it’s finite. For most solar panel setups, the power is only going to flow for as long as the batteries have a charge. The PV cells absorb the energy, the PV cells convert and charge batteries, and we use the battery power to charge electrical appliances. You can think of it in many respects, like a laptop or cell phone battery. It will give you plenty of power but need regular recharging. Some appliances go straight from the PV cells to the appliance, like some water heaters, but most systems charge up batteries to use to deliver the electricity.

Tracking and Sun-Facing Mechanics

 The better aligned solar panels are with the sun, the more power they can absorb and put out. This reason is why a lot of sophisticated systems will actually track the sun, though even these are basically useless at night. This requirement is also why many people who want solar setups in their home have to get themselves a lot of different batteries for their rigs, as they will need to rely on that battery power at night when the sun sets, while the next day the sun’s energy will recharge them.

The good news for people interested in solar energy is that there are companies out there who have a great handle on this and can come in and give you a solar panel rig that will get the job done for you and your family. Though it never hurts to learn a little about the process.
