[QUOTE="binky, post: 528991, member: 490"] after the demise of the FiT, the original high tariff, East/West arrays became the 'new south' for the sales pitches. E/W gives a much better spread of useable power over the day, due South is best for generating FiT payments, but not the best for putting holes in your bills. Horizontal panels are a bad idea, they gather to much dirt. I theory they will output 90% of due south at perfect pitch, in reality, you have to keep cleaning them to get anywhere near that. My own array is on a 5 degree garage roof, between birds and dust in dry weather I wash them at least once a month, weekly currently as I'm on the original high FiT rate, so I'm trying to maximise my earnings. I have seen a few wall installations, mostly on industrial buildings. It has the added benefit of keeping the building cooler, but generally, peoples houses have too much shading from buildings / trees etc etc to make it a viable option. [/QUOTE]
