The average home draws a kilowatt, so two days for a 100 kWh car at 90% efficiency drawing from 80% to 20%. I agree that for the non-paranoid who don’t need to drive far to work the next morning, it could work out fine.
- _ph_ 6y agoDepends where you are looking. In Germany a typical household draws like 10 kWh/day. If you have a large family, then it might be more, but then you might have a second electric car. In any case, it would be an additional option for power failure, whether that is the right approach for a certain situation, depends on that situation.
- brnt 6y agoWe use 1-4kWh/day, and that sort of battery is very easy to find and cheap. Alas, panel installations do not seem to have a socket where you can just plugin a battery, they can only feed back into the grid. At least, not here (NL).
- _ph_ 6y agoYou should look around, here in Germany many companies are selling solar solutions with a home battery integrated. And of course, there it the Tesla powerwall, which is for the same purpose.
- brnt 6y agoThere is the problem that it is illegal to be offgrid in NL. I wonder if that's why there are no inverters sold with a battery hookup. Mind sharing a company name or two? I do live rather close to the border.
- londons_explore 6y agoTypical american houses are much less energy efficient than the rest of the world, by a factor of 2 or more usually. My house in the UK is normally ~150 watts. 20 watts for a laptop, 20 watts for a light, 40 watts for the fridge, and the other 60 goes somewhere I haven't been able to trace.
