Autonomous PV Powered Systems
A majority of autonomous PV systems are stand alone systems used to supply electricity in applications/regions located remotely from the grid. PV systems for stand-alone applications may comprise some or all of the following basic components:
Typical application areas are :
Although PV systems will generally have some means of storing energy to accommodate a pre-defined period of insufficient sunshine, there may still be exceptional periods of poor weather when an alternative source is required to guarantee power production. PV-hybrid systems combine a photovoltaic generator with another power sources - typically a diesel generator, but occasionally another renewable supply such as a wind turbine. The PV generator would usually be sized to meet the base load demand, with the alternate supply being called into action only when essential. This arrangement offers all the benefits of PV in respect of low operation and maintenance costs, but additionally ensures a secure supply.
