Unlike a solar hot water system that uses the sun’s energy to heat water, solar electric or photovoltaic technology uses the sun’s energy to make electricity. Learning from the word itself, the prefix “photo” means “produced by light,” and the suffix “voltaic” refers to “electricity produced by a chemical reaction.” PV technology produces electricity directly from the electrons freed by the interaction of sunlight with certain semiconductor materials, such as silicon, in the PV module. The electrons are collected to form a direct current (DC) of electricity. The basic building block of PV technology is the solar “cell.” Many cells may be wired together to produce a PV “module,” and many modules are linked together to form a PV “array.” PV modules sold commercially range in power output from about 10 watts to 300 watts, and produce a direct current like that from a car’s battery.
A complete PV system usually consists of one or more modules connected to an inverter that changes the PV’s DC electricity to alternating current (AC) electricity to power your electrical devices and to be compatible with the electric grid. Batteries are sometimes included in a system to provide back-up power in case of utility power outages. PV cells can be made from several processes or technologies. They all do the same job — produce electricity from sunlight.
PV systems produce power intermittently because they work only when the sun is shining. More electricity is produced on a clear, sunny day with more intense sunlight and with a more direct light angle, as when the sun is perpendicular to the surface of the PV modules. Cloudy days can significantly reduce output, and of course no power is produced at night. PV systems work best during summer months when the sun is higher in the sky and the days are longer. Because of these variations, it is difficult for PV systems to furnish all the power you need, and are typically used in conjunction with utility-supplied electricity.
