[QUOTE="King Arthur, post: 528677, member: 31673"] That's very interesting! The parents of one of my son's friends are heavily into solar power and have installed a very large PV ground array and also run two Teslas. They are currently planning a battery system and have concluded that second-hand Nissan Leaf's are the way to go as they are cheaper than any dedicated home battery systems, apparently. I think I've previously mentioned my recent stay in an Airbnb property that was an old watermill and the owners had restored the wheel so that it now drives a 15kw gernerator, which supplies all their needs (and more!) and, of course, runs 24/7. So I was surprised when the owner explained that they were looking at a battery system but he said it was because he could charge them for free and then export (ie sell) during times of peak demand. I've read that such a scheme can be profitable even by charging during the cheap night-time rate and exporting at peak rate, so to have 'free' water powered electricity to sell must put them ahead of the curve! Having said that, I'm wondering how long overnight cheap rates will be the norm because assuming more and more people convert to EVs then overnight demand will not be as low as historically normal. This, plus the ever-increasing numbers of smart meters could well mean that electricity pricing becomes more like a stock market operation with prices varying from minute to minute as demand changes. We're definitely living in interesting times! [/QUOTE]
