Gimpy. Okay, here's a basic synopsis for you. Solar cells ese photovoltaics to convert sunlight directly into electricity by converting photons (light particles) into electrons (negatively charged particles). Photovoltaic cells are made of semiconductors and silicon, mixed with other material.
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.
