OK, so come on you solar pushers. Work out where I'm going wrong... 1. The average gas consumption for a UK household is 20,500kwh 2. approx 27% of this is for hot water, 73% for heating 3. approx 70% of the 27% - 19% - could be generated by solar The 20,500kwh is going to cost you on average £700 (uswitch, the cheapest deal being £622). So per year you will save 19% of this or £143. Breakeven in years = install cost / £143. Please help me out. Either it's being installed for less than £2k or it's a pretty **** option right now. I really do want to be convinced, but all these numbers are what everyone in the indstry agrees and accepts. ??????
