Nick's place is down in Zuccoli. It was a six and a half kilowatt system, and we've put on an extra six panels, so it made it up to just over an eight kilowatt, and we put CT monitoring, the smart meter. Now Nick, he's got four little girls, and he can show them now on the app, on when they turn the air conditioner on, how it spikes, and it's a real education for his girls. There's the oldest one is a round about 11, so she really understands on how she can save energy for mum and dad. Nick is a structural engineer. When Nick started building his house and we just started talking about putting solar on. The way the house is and being a big family is that he's got to, with the solar, has now offset a lot of that cost for him. There's six people plus his mum's living there now. And, I think his biggest bill has been $50 a quarter. So, I think that's not too bad. And, the way he's going, his return on investment is going to be probably about two and a half years. He's extremely happy with his system, especially when he gets his power bill.
