We have a house with ideal orientation and these days the Australian government is offering rebates for installing solar panels. I would love to do it but this isn't a very well built house. Award winning builder, good reputation, been around forever, could do it in his sleep - and sometimes I think he did. Brick veneer house with concrete tile roof. On a hillside which sometimes gets strong winds, usually from the other side (ie, not the sunny side). I think we would get an engineer to check things out before we went ahead, or the local people offer the option of having a freestanding structure (designed for houses without the required orientation). All adds to the cost. I'd appreciate it if anyone could tell me what we need to consider, what sorts of questions we should be asking.
