What is Solar PV?

Solar PV

Solar PV panels can be mounted on roofs or the ground in order to absorb as much solar radiation as possible. They convert this solar radiation into DC electricity, Solar panels are made up of smaller units known as solar cells. The most common solar cells are made of silicon photocells. Each cell can generate electricity at about 0.5 volts and just a few Watts of power.

To generate electricity at higher, more useable voltages the cells are connected together to make modules. A number of modules are integrated onto a panel, and many panels can be fitted on the roof of a house. The panels are strung together and then connected to a solar inverter to convert the DC electricity into mains voltage AC electricity.
