[QUOTE="binky, post: 166370, member: 490"] The return on this installation is less than ideal, being small, but as it is a friend of mine I'm not charging them for labour because I want the experience and an install for registration. The roof does have a nice big flat roof on the new dormer, but that is subject to planning as it will be above ridge tile level. Longer term, we are planning to utilise the garage roof, but it will need re-building first to make it suitable. The bit about shading was an opinion from an experienced installer, but having looked at his model of the roof, I have noticed it is structurally incorrect - think this guy is a perfectionist and busy doing bigger jobs, so not convinced he is correct, or wants the job???. 3 firms quoted for the job. 1 declined (didn't really seem to know his stuff), 1 quoted for simple install with no mention of shading, and the third (the perfectionist) quoted for micro inverters on every panel, which makes payback 16 years. I'm working on the basis that there is a compromise to be had that brings price down to make it viable. If nothing else it has been a great learning opportunity, and a real eye opener for PV and problems assocciated with real installations. [/QUOTE]
