Solar PV system converts sunlight into electricity. It consists of the following basic components:
The module is usually made in panel. The conversion of sunlight into electricity happens here. The electricity generated is DC (direct-current), i.e. the type of electricity that you get out of a normal battery.
It is an electrical device that converts DC into the more useful power supply of AC (alternate current), i.e. the type of electricity that TNB supplies to your home.
It contains protective devices for the system.
It is also called revenue meter. It is similar to the existing TNB meter you have. It is used to measure the amount of electricity generated from the solar PV system. The unit is kWh.
