alt Hacker NewsLook into a battery + inverter + optional solar on a time of use tariff, you can be always off peak. Payback probably isn't very long.

Solar is great. I'm highly skeptical that a battery + inverter (w/o solar), using time-of-use for payback would ever make pure financial sense.
In fact, if it DID make financial sense, wouldn't companies already be buying up empty/cheap space and then turning a profit after the payback period? Why aren't they?
There are other reasons to do this, but purely on the financial side, I'd want to see the numbers on this one. Again, this isn't about solar, the claim was about battery + inverter + time-of-use paying for itself.
Can't - building prohibits everything along those lines
In the UK, solar is fairly ineffective in the winter as the sun barely comes over the horizon for not many hours a day.
Has anyone done this on the cheap? I've gotten a few quotes with a payback period of 8-12 years, which isn't great.
