We ended up with the just over 10 kilowatt panel system, but we decided that that would be enough to charge a battery fully every day, and satisfy our daily consumption, and still carry us over for an extra 10 kilowatts with a battery in the evening. Even though we will have heating for hot water service, which will kick in on the off-peak rates at night and probably use up 10 kilowatts per night. The battery in the end, it was the one that was recommended to us in terms of compatibility, as well as the cost factor. And for that, the whole picture fitted in well.

Over the next five, six years maybe, a large proportion of that investment will be repaid. That's, yet to be seen over the next 12 months. I'll probably have a better idea. My wife, she still wants to see how much our bills will shrink and how long it'll take to repay the system, because it is a significantly larger investment than some of the cheaper companies that do installations. However, I feel that over the next 10, 15 year periods, that investment will prove itself as being a good one.
