What is a Photovoltaic System
Introduction
You don't need to understand the detailed physics of how a solar electric system works to understand its appeal: investing in a solar electric system allows you to produce your own electricity with no noise, no air pollution, and no moving parts while using a clean, renewable resource.
A solar electric system will never run out of fuel, and it will help reduce the amount of greenhouse gasses emitted by coal and natural gas fired power plants.
Due to these unique characteristics, solar electric technology has been called "the ultimate energy source for the 21st century"
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.
