Solar ElectricDemand for electricity requires vast amounts of sophisticated solar
collection. Also known as photovoltaics (PV), solar electric technology
features large arrays of collectors made up of silicon-coated cells.
When sunlight strikes the surface of a PV cell, electrical fields are
directed to electrons, resulting in a flow of current. PV electric
systems require major components to properly conduct, control, convert,
distribute, and store the energy produced by the array – items such as
a power inverter, battery bank, system and battery controller,
auxiliary energy sources and sometimes the specified electrical load
(appliances).
Photovoltaic systems can be designed to provide DC and/or
AC power service, can operate interconnected with or independent of the
utility grid, and can be connected with other energy sources and energy
storage systems. The current high cost of PV modules and equipment (as
compared to other solar applications) is the primary limiting factor
for this technology today.
