Question

With a neat diagram explain solar photovoltaic power plant.

Answer 1

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
