Polycrystalline 90W 12V solar panel being used in space exploration and other forms of transportation
The top uses for solar panels
1) heat for your home
2) power pumps
3) 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.
4) powering your home, camper, cabin, tool shed, or any other building for that matter.
5) 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.
6) 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.
What are Solar Panels Made of?
Photovoltaic (PV) solar panels are made up of many solar cells. Solar cells are made of silicon, like
semiconductors. They are constructed with a positive layer and a negative layer, which together create an
electric field, just like in a battery.
