Help Me Understand the Economics of a Battery
I have a 9.6ish kW solar system. It is monthly net metering wth no carryover, so any excess I produce only pays me between $0.01 and $0.035 per kWh. Since the system was installed, I have produced excess every month, but most months it’s not even enough to cover the connection and other fees, but it’s still almost free so that’s good.
If I were to get a battery, as far as I can tell it would only mean that instead of trading daytime electricity for nighttime electricity with the utility, I would be doing it with the battery. Since the utility does it for free, what benefit does a battery provide? Are there utilities that don’t even offer net metering within the monthly billing cycle?
