PhotoVoltaics: Basic Design Principles and components
If you are thinking of generating your own electricity, you should consider a PhotoVoltaic (PV) system-a way to genereate electricity by using evergy from the sun. These systems have several advantages:They are cost-effective alternatives in areas where extending a utility power line is very expensive;they have no moving parts and require little maintenance;and they produce electricity without polluting the environment.
Hundreds of cost-effective applications for PV systems have been developed. In the United States, PV systems must have unobstructed Southern exposure. Where you live, will determine the number of PV modules you will need. In addition to the PV modules, you will need to purchase balance-of-system (BOS) equipment. The National Electric Code cntains provisions and requirements for PV systems.
