Diagram of solar photovoltaic power plant :
Explanation:
Solar power plant consists of following components:
1. Photovoltaic cell panel: Its function is to convert sunrays directly into DC electricity.
2.Battery charge Controller: It protects battery from over charging and it prevents battery from over discharging. In this way it increases life of storage battery. (OR a charge controller is needed to ensure the battery is neither over nor under-charged)
3.Storage Battery: Its function is store DC electrical energy generated by P.V. cell which can be used whenever required. Generally battery having long life are used .There are two types of battery: 1. Lead acidic battery 2. Nickel cadmium battery
4.Inverter: It converts DC supply into AC supply.
5. Step-up transformer: It step-up input voltage to utilization voltage e.g. 230V
