He wanted to try and compensate for his electricity consumption. The only way he could feasibly do it is to put a bigger solar system on it. He couldn't reduce his power consumption in any way. So the next best thing, for him was to put a bigger system on, higher capacity system. He wanted to be able to send a little bit of power back to the grid as well. Hence this the system sizing, and he was on a single phase connection. So with that, we opted for the biggest capacity inverter we could do without limiting what he exports to the grid.

They wanted to upsize, they wanted a system better suited to their needs. And the fact that the system that was existing was six to seven years old, had micro cracks, it was inevitable that it was going to fail in a short period of time. And it's just financially, it's not worth putting a system beside another system like that when you can just pull the whole thing off and start from scratch, for really not a lot more cost-wise. We took a 1.5 kilowatt system off and put a 5.6 kilowatt system on. That system given the layout of this system is going to generating somewhere between, on a good day 30 to 34 kilowatt a day. During the winter months obviously it's not going to be as efficient, but we're still going to be pulling 20 kilowatts plus a day on the good days. The old system was generating, I think about five kilowatts a day. So we've added another 80% of power production onto what he had.

The thing with pulling an old system off the roof is, that we're still able to pull the rebate for the value of the old system, as in the kilowatt value of the old system. So that brings the cost of the new system down as well. So again with old technology sitting beside new technology with the old inverters, old panels, the technology we had back 2012, 2013, is nowhere near as good as the technology we have now. So it just makes sense to take the older system off, get rid of any potential failure, and just put a new system on.
