Solar panel. Solar panels absorb the sunlight as a source of energy to generate electricity or heat. A photovoltaic (PV) module is a packaged, connect assembly of typically 6x10 photovoltaic solar cells.
Solar panels use only the sun's energy to produce energy we can use. They collect the sun's rays and store them in a battery or send them on to the grid. Basically, they use a â¦ more environmentally friendly energy source. Solar panels conserve energy and help the planet from global warming.olar energy provides a heat source for all living things on earth. we also transfer solar heat into electricity and other types of energy, using solar panels. however, only a â¦ portion of the suns energy makes it to earths surface because the ionosphere reflects some of the rays back into space.
