Well it's an old house, it has a large air conditioning requirement in summer. So you know it was financial, but it's also partly environmental as well. So you know, there's no question I was going to go ahead with such a system, it was a question of how big it was, who was going to install it, and who's going to be the manufacturer for the panels and the inverters.

Because we've got a large steep roof here, it's like a 35 degree angle, and I particularly wanted landscape orientation rather than portrait, and that makes it difficult with the roof the way that the purlin spacing is. And I'd done some sort of research into other ways of fixing to a metal roof, where it fixes directly to the corrugated sheets, not necessarily to the purlins.

They did an excellent job, they were very careful on the roof when they came. What particularly impressed me was when they did the wiring inside the roof cavity, everything was in conduit, there's no loose wires. Everything was really tidy, going right down to the switchboard, and the choice of the panel system. They're excellent because they're running around on your roof, and you want the installation done correctly. Because you know, you get winter storms coming in, you don't want panels lifting off. You want it all done correctly. And so far it's been through quite a few storms, hasn't batted an eyelid at all.
