How does it work?
A solar photovoltaic (PV) cell is an electronic devise that produces electricity when light falls on it. As the light is absorbed by the PV cell it frees up electrons present in the cell. As the electrons move from the cell, they carry an electrical charge.
A single PV cell can only absorb a small amount of light at a time. Consequently several cells are usually interconnected to form Panels (modules) to provide larger amounts of electricity. Panels can be interconnected to form a photovoltaic array; these vary in electrical power from a few watts to several thousands.
The PV array produces Direct Current (DC) while the electricity from the grid is Alternating Current (AC). All our installations are grid connected which means that DC electricity has to be transformed into AC. This is done by an Inverter.
A Generation Meter keeps track of the amount of electricity produced by the system.
The electricity from the system is used to run appliances in the property. Any surplus goes back to the grid.
