Solar Energy Solar energy means using the energy of the sun to provide electricity, to heat water, and to heat or cool homes, communities and businesses. Sunlight is a clean, renewable source of energy. It is a sustainable resource, meaning it doesn't run out, the supply can be maintained.

How does solar work?

Thermal Solar

Thermal solar involves absorbing and converting sunlight into heat. For low temperature applications for households, communities and small to medium businesses solar collector systems can reach efficiency levels in excess of 75%. The key design consideration for thermal solar collectors is how to prevent the absorbed heat from being lost to the outside environment. This is where evacuated tubes have a great advantage, with the vacuum greatly reducing heat loss. The task of the solar collector is then to efficiently transfer the absorbed heat to water which is circulated through the panel. Solar collectors are ideal for both domestic and commercial applications were hot water, heating and even cooling is required.

Photovoltaic (PV)

Photovoltaic (PV) solar cells are used to harness the energy from the sun and directly convert sunlight into electricity.
