Enough solar radiation strikes the earth every day to meet our energy needs for a whole year. Photovoltaic (PV) systems are renewable generation systems that directly convert energy from sunlight into electricity.
PV systems work anytime the sun is shining, but they produce a greater amount of electricity when the sun is more intense and strikes the panels directly. As a result, PV output peaks mid-day when daily demand is greatest.
