Solar in California is often breakeven after 4 to 7 years. Enphase enables microgrid systems, and the IQ8 can keep your house powered even when the grid is down

Solar in California is often breakeven after 4 to 7 years. Enphase enables microgrid systems, and the IQ8 can keep your house powered even when the grid is down, and even without batteries –– something never before possible. https://enphase.com/sites/default/files/2021-10/IQ8SP-DS-0002-01-EN-US-2021-10-19.pdf https://enphase.com/sites/default/files/2021-10/IQ8SP-DS-000... Worth nothing that PG&E is working with CA Democrats to try to kill rooftop solar. They want renewables, but only if distributed using their (badly operated and overpriced) grid.

I'm happy with our enphase system. We have batteties from them too. The Democrats (and Arnold) pushed back hard against the proposed NEM 3 rates that would have killed rooftop solar. I have nothing nice to say about PG&E.

While I can't say anything useful about PG&E, net metering is problematic though. As used right now in many regions of the world, it is a large and inefficient subsidy to relatively affluent solar roof owners like you and me. Where I live, a different regime is being introduced: - a capacity tariff: a base grid charge, calculated based upon quarterly average peak consumption - a feed-in rate: a wholesale rate compensation for injecting self-produced green electricity into the grid (my current rate: 0.064€/kWh) - a retail rate by one's electricity provider (my current rate: .02869€/kWh) - subsidies for installation of solar (up to 300€/kW peak) and storage (up to 30%) This at least conceptually incentivises both of solar installation and peak shaving. Solar is less ridiculously profitable for me, but still a no-brainer in terms of profitability.
