Solar energy is radiation from the Sun that is capable of producing heat, causing chemical reactions, or generating electricity.
Most PV panels produce the most power in direct radiation. Ø A 50W bulb connected directly to a 50Wp panel may not consume 50W, even in bright sun. Ø Car batteries are designed to supply quick bursts
Sunlight is composed of photons, or particles of solar energy. These photons contain varying amounts of energy that correspond to the different wavelengths of the solar spectrum. A PV
