I have exercised my 10 day cooling off period and canceled the contract with Blue Sky Solar Energy and I am now looking at the following options on a tile roof in Brisbane @ 20 degree slope WEST facing 270 degrees (only choice
sadly with around 12 % loss)
Any further feedback would be appreciated. You guys are awesome with your knowledge and I really appreciate what you have given me. I do not feel deterred by the western orientation as it certainly appears to out-perform the eastern here in Brisbane.
