GENERAL DESCRIPTION OF PV / SOLAR SYSTEM
Grid-tied PV / Solar System
PV/Solar Panel (Module) or Array
Fig. 2.2 shows a Block Diagram of a typical Grid-tied PV / Solar System. In this system,
the Solar Panels (Modules) / Arrays directly feed to an inverter and the inverter is
connected to an Electricity Transmission and Distribution System (referred to as the
Electricity Grid) such that the system can draw on the Grid's reserve capacity in times
of need, and feed electricity back into the Grid during times of excess production.
