Electricity generated by solar panels is referred to as PHOTOVOLTAIC energy. This tongue twisting word is often shortened to "PV," and thus we refer to a solar system that generates electricity as a PV system. PV technology produces electricity directly from electrons freed by the interaction of sunlight with a solar panel made of semiconductor material. The power provided is direct current (DC) electricity. The basic building block is known as a cell. Many cells put together are known as a module, and many modules assembled together form an array. A PV system will consist of an array of modules generating DC electricity, an inverter, and sometimes battery storage back up with charge controller. |
