I have been asked to provide an estimate for the installation of a 2Kw system on each of 13 houses. The energy assessment does not make it clear as to whether it has to be 2Kw installed or 2Kw net. Most of the houses will have front facing dormers which by my calculation mean a maximum of 5 x 250w panels can be fitted to the front. Can you put the rest on the back? It will be pretty much North facing. Apparently other companies have said they can do it for circa £50,000 fully fitted. I can see how they can do it without taking into account efficiency levels but how stringent are building control on this? My guessing is other firms are putting the panels wherever, not maximising the systems and just concentrating on their revenues? Is this how the industry is?
