It's very common, I've got a number of customers that don't even get a power bill these days. From a single-phase at a five kilowatt inverter. We can oversize that by 33% with the clean energy rule, so we can claim our, the STCs, or the rebate as people refer it to. So that's your sizing of your systems. And I always say to people, is work on your budget, put as big a system as you possibly can on, so that you're exporting to the grid. Yeah, I get a lot of customers now, that because I put a good quality system on, they're not getting a power bill, they're getting a credit. And so the credit builds up, and I was speaking to a lady the other day, they've never had a power bill since the system has been on there. And they got up to a stage of, I think she said something like $10,000 in credit, so they're slightly drawing it off and doing other things with it. You're laughing all the way to the bank, as they say.

Well, the challenge for solar is trying to design a system that you're going to get on that roof. They've got all these fancy designs on roofs and the only time that a person that owns the house would ever see it is if they fly over, to put a drone over, to have a look at it. You've got to look at solar in the future is to have it so that it's north facing at around about the 12 degree.
