Photovoltaics is a proven technology used globally for reliable solar power generation
and is particularly suitable for smaller installations
These photovoltaic cells are installed on a roof. At the heart of photovoltaic cell is a semi-conductor material which can be adapted to release electrons, the negatively charged particles that form the basis of electricity.
The most common semi-conductor material used in photovoltaic cells is silicon, an element most commonly found in common sand.
There is no limitation to its availability as a raw material; silicon is the second most abundant material in the earth’s mass.
They generate power from the sun which can be fed directly into the national grid.
This power can be used either directly in the building where it is installed or it can be 'sold' to an existing electricity supplier.
