Solar Thermal systems have been around for the past 30 years. They consist of collectors or panels that harness solar energy to heat water for supply to your property’s central heating and/or hot water.
In the UK, solar thermal panels are almost exclusively ‘Classic Flat Plate’ or the more modern and efficient ‘Evacuated Tubes’. They work by absorbing solar radiated heat, transferring it to a glycol solution, which is then used to pre-heat an indirect hot water cylinder.
As such, your conventional heating system will require less energy to achieve the desired hot water delivery temperature, which must be greater than 60ºC.
They can be sited on both pitched and flat roofs and a well specified solar thermal system can supply around 55-70% of domestic hot water needs over the year in the UK.
For domestic systems the Government's Renewable Heat Incentive has been delayed and will be implemented as part of the "Green Deal" initiative in Autumn 2012.
For commercial, metered, systems the Renewable Heat Incentive will be introduced in July 2011.
