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.
The invention of solar panels and batteries enhanced the harnessing and storage of solar power. Solar panels are used to collect radiant energy. Consequently, the energy is stored in the batteries. The stored energy can be used to run home appliances and in the operation of machinery. At night, radiant energy is not available. Therefore, excess solar power stored in batteries is used to power home appliances and machinery.
