Load shifting is a thing. Create the conditions for solar overproduction, and we will adapt to use it. Hot water production can be done primarily during the day. Thermostats can treat houses as thermal batteries. And batteries will likely become a lot more common. A single night’s worth of battery storage doesn’t add all that much to the cost of a house. 30 kWh of lithium iron phosphate batteries can be had for $10k.
- rr808 4y agoYes but you can't load shift over seasons. The OP is in Belgium, in Winter solar is not strong enough during the day to charge your batteries to get you through the night.
- ericd 4y agoRight, the point is that overprovisioning solar is not a bad thing, and that it shouldn’t be restricted. Not saying that it’s sufficient on its own. Unless it somehow became so cheap that it was reasonable to overbuild to an extreme, and we had good energy sinks for peak times. If we became serious about direct air capture, for example, there might be an argument for it.
