Solar Energy

Solar thermal systems utilise solar radiation collected via panels to provide hot water. Solar panels, also known as collectors, fitted to a building’s roof use the sun’s heat to warm water, or another fluid, which passes through the panel. The fluid is then fed to a heat store e.g. a hot water tank, and helps provide hot water or a source of hot water for the building’s central heating system. Solar panels work throughout daylight hours, even if the sky is overcast (although less effective) and there is no direct sunshine, which means they can make a useful contribution even during the winter by pre-heating the water in the storage tank. Your boiler or heat pump will boost the water temperature.
