THE NEED FOR RENEWABLE ENERGY

The sun is the source of most of our renewable energy supplies. Energy from the sun is clean and abundant. There is a widely held opinion that the UK does not have enough sunshine to make solar systems worthwhile. In fact parts of the UK have annual solar radiation levels equal to 60% of those experienced at the equator.

However, this energy is not received uniformly throughout the year. Some 70% of UK annual radiation is received over the period April to September and 25% is received in the months of June and July.

Solar water heating technology is about using this energy and converting it into a form that can be used in buildings and industry, thus displacing conventional energy sources.
