Fully agreed. We live in the Bay Area as well, and put in solar a couple years ago. Due to the shape of our roof, we were only able to put in a ~68% system (the rule of thumb is to target generation at about 80% of your average use for best ROI) but even with a slightly-undersized array, our savings have been immense, as we no longer need to pay Tier II or Tier III rates, even in the middle of summer.
AFAIC, if you own your home, it's a complete no-brainer. And our time to payoff is going to be around 4 years, tops.
- matt_wulfeck 9y agoI'm surprised they left you on a tiered system. They forced us on to a time of day plan which is quite expensive
- Baeocystin 9y agoI think we just got lucky. The pg&e rep pushed the TOU plans pretty hard, but we asked to stay on the tiered system, and they didn't say no. Our neighbors, who got a system just six months after we did, were required to switch. This was almost exactly two years ago. From what I understand, the plan we're on is going to be forcibly retired in 2020. Hopefully by then powerwalls will be cheap enough to get us through the 5-9 hump during summer on the Time of Use system.
- matt_wulfeck 9y agoBecause you get the retail value of the power you push into the grid, the TOU plans aren't that bad because you get more "money" for your excess power. You pay more when you use, but they pay you more when you produce.
