Frank's gone with solar because his house is in the middle of a bush block. Because it is in the middle of a bush block it is going to cost them, I don't know, unquoted thousands to get power to that. The cost of a solar system, I think that was about $40,000 thereabouts. Cheaper than putting grid power in. The size of the system again, it's sized to be able to run a modern house, obviously the solar we've got East and West, so we get the maximum capacity into the system that we're using. The customer has gotten energy efficient appliances, they've still got an electric oven. I think they've still got split systems and whatever they're going to be running of it. You have to take each customer individually, it's not a general hard and fast rule. An off-grid system say, the first thing people are going to look at, it's how much is the system going to cost compared to how much it's going to cost to put power in.

So the essence with Frank is that we've got to get a system on, that is going to run a modern house. We needed to give him something for the longevity of this system is going to give him the power of a reasonable timeframe. The system's oversized, so it's always going to be running at the maximum capacity, of the 25 year manufacturer warranty of it. The performance at the end of that 25 years is going to be far superior to any of the other products that are out there on the market.
