Our solar technology has worked amazingly well throughout the sunny UK summer this year.
– The solar thermal panels have provided us with hot water on all but ~two days since April. And that’s heating a 250 litre water tank to between 55 to 70 degrees Celcius each day.
– The solar PV panels have done their job too. The electricity meter runs backwards when the sun shines. The current meter reading is only 300kWh higher than it was at the end of March. At 12.4p/kWh, that works out at a cost of £37.20 for all our electricity/hot water for the 4 months from April to July (or £9.30 per month) (excluding service charge). We don’t have gas or oil, so this will be our total spend on energy this summer.
Our usage will go up once the days get cooler and we start to heat the house. Generation will decrease once the clouds re-appear. But the performance of the system has surpassed our expectations. It’s wonderful to be running on sunshine!
