PV is the easiest renewable electricity source to incorporate into buildings. The electricity is supplied at the point of use, thus avoiding the losses which occur in electricity distribution (these average 7% in the UK).
It can be used at any scale – from less than a kWp on an individual home up to MWp scale systems on large public buildings – and is simple and reliable. Because of this.
It is a valuable way to raise awareness of electricity supply and use, and helps highlight the potential for renewable energy. Several schools that have won Ashden Awards like Cassop Primary School and Ringmer College have installed PV, to supply part of their electricity and as an education aid.
