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.
How Solar Works. We can change sunlight directly to electricity using solar cells. Every day, light hits your roof's solar panels with photons (particles of sunlight).The solar panel converts those photons into electrons of direct current (DC) electricity.The electrons flow out of the solar panel and into an inverter and other electrical safety devices.he Size of Your Solar PV System. The size of your solar system depends on several factors such as how much electricity or hot water or space heat you use, the size of your roof, how much you're willing to invest, and how much energy you want to generate.
