Hot water from the sun!
Solar thermal was one of the first renewable technologies installed by the early adopters and was also the cheapest.
In commercial installations solar thermal is a Renewable Heat Incentive (RHI) eligible technology.
After all these years on is solar thermal still value for money? Yes. Raising hot water can be a costly task and a considerable burden on business especially if your main energy source is LPG, Oil or electricity. Solar thermal will take water to a respectable temperature depending on system and location, however at this point the expensive work is done and again dependant on the requirements only a small top up may be required.
Solar thermal is an excellent technology if there is a need for hot water, however unlike solar PV you cannot export the thermal energy.
Commercial sites such as care homes, leisure centres, sports clubs and caravan sites that all have a demand for hot water could benefit from a solar thermal system. In fact the bigger the heat load the more viable the technology.
