The top ten uses for solar panels include:
> heat for your home
> power pumps
> indoor and out door light battery charging which can be a
beneficial if you have a reserve battery bank
that is charged through the day while sunlight is present and is
used through the nighttime hours. It can also
be used for simple solar panels to collect sunlight and convert it
into electricity.
> powering your home, camper, cabin, tool shed, or any other
building for that matter.
> when heating swimming pools, a solar hot water heating system
utilizes the solar hot water heating
panels, that can be mounted on your roof to collect the sun’s heat
and then is circulated to the pool.
> Solar panels are also being used in space exploration and
other forms of transportation.
How Do Solar Panels Work?
When photons hit a solar cell, they knock electrons loose from
their atoms. If conductors are attached to
the positive and negative sides of a cell, it forms an electrical
circuit. When electrons flow through such a
circuit, they generate electricity. Multiple cells make up a solar
panel, and multiple panels (modules) can be
wired together to form a solar array. The more panels you can
deploy, the more energy you can expect to
generate.
Solar panels get energy from the sun for people to use. There are
two types of solar panels, those that
collect heat (thermal), and those that produce electricity
(photovoltaic). Heat from solar panels is often used
for space heating and for hot water.
