The Earth's magnetic field, a protective shield generated by the movement of molten iron in the planet's outer core, plays a crucial role in sustaining life. It guards us from harmful solar and cosmic radiation and provides a reliable means of navigation. However, this magnetic field is not static; it undergoes periodic changes, one of the most dramatic being a geomagnetic reversal. In this phenomenon, the positions of magnetic north and south switch places. Though the concept might seem alarming, geomagnetic reversals are a fascinating and natural part of Earth's history.

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
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 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
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.
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.
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.
Will the rise of solar and other renewables torpedo the oil and gas industry?
The world has come a long way since Faraday produced an electric current from a magnetic field and invented what we now know as electricity. This ‘electricity’ has gone on to permeate every sphere of human life and ushered in an era of increasingly sophisticated devices and appliances. Every major industry requires electricity to function and according to The Economist, current global consumption is around 15 terawatts of power.
Installing Solar Panels in California
Earlier this year, regulators in California approved a
plan to require solar panels on new home construction throughout the state and
set 2020 for everything to go into effect. The plan will require solar panels
to be installed on almost all new single-family homes which will add nearly
$10,000 onto the cost of a new home. The plan is a welcome addition for
statewide homebuilders as well as solar power companies and utility companies.

Crowdsourcing Solar Farms Using Satellite Images
SolarEnergyMaps.com has been crowdsourcing solar roofs, solar parking, and solar farms for several years. We do this manually by zooming down to appropriate levels to view images. Solar farms, solar roofs, and solar parking structures are easy to find as long as satellite images are updated. We ask our users to put a yellow pin on our map and submit a link to a news article about the solar location.
Crowdsourcing solar farms using satellite images is an innovative approach that leverages the power of collective intelligence to identify and map solar installations around the world. Here's how it works:
Satellite Imagery: High-resolution satellite images are collected from various sources, including commercial satellite providers and publicly available satellite imagery archives. These images capture a wide area and provide detailed views of the Earth's surface.
Image Analysis: The satellite images are processed using advanced image analysis techniques, including machine learning algorithms and computer vision, to identify potential solar farm locations. These algorithms can detect patterns, shapes, and characteristics associated with solar panels and installations.
Crowdsourcing Platform: A crowdsourcing platform like solarenergymaps.com or an application is created where volunteers or users can access the processed satellite images. The platform provides tools and guidelines for users to annotate or mark areas where they identify solar farms or solar panel arrays.
User Contributions: Users, often referred to as "citizen scientists," contribute their time and effort to review satellite images and mark potential solar installations on the crowdsourcing platform. They may manually draw polygons or use other interactive tools to highlight solar farm boundaries or put POI pins in the map.
Data Validation and Quality Assurance: To ensure the accuracy of the crowdsourced data, multiple users review and validate each marked solar farm. Algorithms can be implemented to compare and reconcile different user annotations, identifying areas of agreement and resolving discrepancies.
Data Integration and Analysis: Once the crowdsourced data is validated, it can be aggregated and integrated into a comprehensive database or map of solar farms. This data can be analyzed to gain insights into the distribution, capacity, and characteristics of solar installations worldwide.
Benefits of Crowdsourcing Solar Farms Using Satellite Images:
Scale and Efficiency: Crowdsourcing allows for a large number of satellite images to be analyzed simultaneously, enabling the identification of solar farms at a much larger scale and faster pace compared to manual analysis.
Cost-Effectiveness: Leveraging the power of citizen scientists reduces the costs associated with manual labor or specialized expertise required for image analysis.
Global Coverage: Crowdsourcing can engage volunteers from around the world, leading to the identification of solar farms in remote or inaccessible areas where traditional data collection methods may be challenging.
Data Accuracy and Validation: By involving multiple users in the annotation process and implementing validation mechanisms, the quality and accuracy of the identified solar farms can be improved.
Community Engagement: Crowdsourcing solar farms encourages public participation and citizen engagement in renewable energy initiatives, raising awareness about the importance of solar energy and sustainability.
While crowdsourcing solar farms using satellite images is a promising approach, it's important to note that the accuracy and reliability of the data depend on the quality of satellite imagery, the effectiveness of image analysis algorithms, and the level of user participation and validation. Therefore, ongoing monitoring, verification, and refinement of the crowdsourced data are necessary to maintain its accuracy and usefulness.
The future of these maps will depend on technology and using AI or artificial intelligence to train mapping software to find solar energy locations. See the link to review an example provided by SyndicatedMaps.com.
