Interesting, I’d not given much thought to over-production. In fact, in the UK, selling back to the grid is part of the “payback” plan, despite rates being very low. You say storage solutions, presumably batteries in a domestic setting, may be short lived, how so? Again, I had thought that a PV installation, with batteries would have been the best solution for the owner who then avoids more pull from the grid. In more northern climes, such as the UK I would expect there to still be more take from. The grid as per your images of course.

I would like to invest in PV and batteries as we have a large roof space. My best calculations are a payback period of around 14 years given current high electricity prices. My wife and I aren’t sure we would still be living here for that long as we could well downsize. Perhaps we would be, who knows?? Also if, by some miracle, electricity prices come down, then the payback period extends.

On a related note, she does want a chest freezer installing so maybe we could take advantage of your experiment to bring the payback down [emoticon:44a8a53ad3364ea78a16c5a3229f75bb]
