Ten years ago, if we had've been talking about environmental benefits of putting solar in, it wasn't really something that was discussed. And nowadays I'm finding it's probably a 50/50 split where people are saying, I want to do the right thing by the environment, I'm conscious of the effects of coal-fired generators and that side of things. So people, they make a conscious decision based obviously on what they want, but the environment does come into the play now.

Yeah, money's a great motivator, and if you can save a lot of money, especially for some of the people that are retired, they've got money invested, and if they can put a solar power system in that's going to save them money, then their investments are going to sustain them for a lot longer as well. So they'll look at selling power back to the grid and depending on who your energy retailer is, you can get 8, 10, 11, 12 cents a kilowatt, you can get up to 20. So it really comes down to just trying to balance whether it's worthwhile getting a higher discount on the power that you're buying, or whether you get a higher feed-in rate for the power you're selling back to the grid. The feed-in tariff, in a lot of cases, if you're getting that 12 cent mark, 11, 12 cents, that seems to be about where the market is.
