A residential or commercial solar-energy system uses solar PV modules, made up of photovoltaic (PV) cells, to harvest the sun's energy and convert it into electricity that can be used to power your lights, appliances and other electrical devices in your home or business. Every day, light hits your solar panels (roof mounted or ground mounted) with photons (particles of sunlight). The solar panel converts those photons into electrons of direct current (DC) electricity. The inverter converts that DC power (the type commonly used in batteries) into alternating current or AC power. AC power is the kind of electrical power that your television, computer, and everything else uses in your home or business.A PV system needs unobstructed access to the sun's rays for most or all of the day in order to be effective. Shade on the system can significantly reduce energy output. Climate is not a major concern because PV systems are relatively unaffected by air temperatures, and snow cover typically melts quickly because panels are positioned directly in sunlight. Abundant year-round sunshine makes solar energy systems useful and effective nearly everywhere.
