HOW DOES SOLAR ELECTRICITY OR “PV” SYSTEMS WORK?
A. Photovoltaic’s, also known as “PV,” produce electricity from the sun. The solar “cell” is the basic building block of PV technology. Solar cells are wired together to form a PV module. PV systems begin with the solar module. Modules gather solar energy in the form of sunlight and convert it into direct current (DC) electricity. The more sunlight they receive, the more electricity they produce. Solar modules are the heart of the PV system. In essence, they are the power generators. To convert DC power to alternate current (AC) power, the type of electricity used in your home, a device called an inverter is used. Depending upon the size of the PV system, inverters may be mounted by the PV manufacturer right on the back of a PV module. Inverters may also be wall-mounted separately from the PV system, but within close proximity to the solar panels.
