Solar photovoltaic technology (SPV) is primarily a semiconductor-based technology used to convert solar radiation into direct electricity. A basic PV system comprises PV modules and the balance of systems (BOS). Balance of systems includes support structure, wiring, storage, power electronics, etc.
Components of PV system
A PV system consists of the following components.
1 PV panels (also known as solar panels)
3 Charge controller
5 Mounting structure and tracking device
6 Interconnections and other devices
BOS (Balance of system) includes all the components mentioned above except for the PV panels. In other words, a PV system consists of a PV panel and BOS. However component varies from application to application. Sizing of the systems is based on some design practices.
