With massive rebate programs and tax credits being issued by state and federal
governments, using the sun to generate electricity is very popular. So, how
does it work?
Generating electricity from the sun is all about converting sunlight into power.
Importantly, the process has nothing to do with converting the heat produced by
sunlight into energy. This common misconception leads to a lot of confusion
regarding solar systems.
The technology behind solar systems is known as photovoltaic technology.
Essentially, this technology involves using sunlight to create a chemical
reaction. During the chemical reaction, electrons are released from the
relevant material and collected by tiny wires. This process creates a direct
current of electricity. The electricity is then converted to usable alternating
current electricity and stored in a battery or fed into a utility grid system.
Solar platforms use this exact process to produce energy. The arrays are made up
of small squares called photovoltaic cells. A collection of these cells forms a
single panel and a collection of panels makes up a ?solar array.? The size of
your array is entirely dependent upon the amount of electricity you want to
produce.
The photovoltaic cells in a solar array are where the action happens. The cells
are typically made with crystalline silicon under a glass cover. When sunlight
hits the crystalline silicon, the material reacts by kicking off electrons.
Tiny wires built into the cells collect the electrons in the form of an
electrical current. This current is then sent to an inverter, which converts it
to usable electricity.
The biggest issue with solar platforms is how efficiently they convert sunlight
into electricity. The answer depends on how much you want to spend. Top brands
will convert at roughly 15 percent efficiency. Less expensive brands will
convert at 5 to 10 percent efficiency. The more efficient the panels, the fewer
you will need.
It has become clear that our reliance on fossil fuels is only going to lead to
further problems, whether political, environmental or economic. Advancements in
solar technology as well as incredible tax breaks and rebates make using the
Sun as an energy source a viable solution for you.
