This June it generated 802 kWh. Which is well below my average across all Junes since install. My average for all 5 Junes is (802+907+988+892+1010)/5 = 919.8 kWh average for the month of June.

In June of this year I used 367 kWh more than I generated. So 367+802 = 1,169 kWh used (about half of what you used.)

I'm confused. In a previous post you stated that your June electricity bill before solar panels was about \$600. Now you are saying that if you didn't have solar panels that you electricty bill for June would be about \$120. Why the big difference?

No solar system is going to pay for itself if you're using that much juice. (Granted, on the other end of the electricity spectrum, no system is going to pay for itself for me, either -- because it doesn't make any sense to go solar when I spend \$700 per year on electricity.)
Yeah, I feel bad about it but the Mrs wants the house at 72F. (Actually, she would like it cooler so the 72F is a compromise).

Jonathan, if you had use the \$25k for energy efficiency projects (also has tax credits) and moved to time of use rate plan, don't you think that you would be about even in the finance analysis? How much electricity did you use in June?

A few factors like number of people in the house during peak hours have changed and our energy usage patterns have changed over the years especially during peak usage periods. This is also in So Cal. We do not have solar on our home in Henderson, in large part due to the fact that energy from NV Energy is so much cheaper than from So Cal Edison. A huge amount of our summertime usage used to fall under tier 3 and 4 billing rates which are currently 25 and 31 cents respectively. Tiers 1 & 2 are charged at 15 and 19 cents. It was not at all difficult for us with 4 adults and a baby in the house during the better part of the hottest parts of the day to quickly find ourselves in those higher tiers. 1000 kWh used in tier 4 is 310 bucks. Add on the monthly usages from the other 3 tiers and it all adds up way too quickly. These days, members of the household have jobs and the baby is often in day care or at a babysitters etc so there is no need to have the AC cranking during the hottest parts of the day. Since the addition of Solar Panels I don't recall having strayed into the usage beyond tier 1.

Thanks for the explanation. Given your current electricty usage, would you still go solar in CA and how long would it be before the break-even point is reached?

Hard to say. Probably, though I would get a smaller system to compensate for our reduced usage even though we still do use more than we generate today. Maybe a 4 kWh system would be more in tune with our current usage. Oh and as for break even. I don't know. I originally calculated an 11 year BE on my current system. 1 thing I can say for sure though is it would never be a 25 year BE as someone indicated earlier in this thread. Anyone buying solar with a 25 year BE is way over buying for their needs.

My house actually is small, and my electric usage seems excess, but I had a new meter installed
and unless my neighbors have some underground tap. its been consistent.

I keep my house at 82° (my comfort zone) during the heat wave I was running a chilly 79-80°
I have a pool, and a hot tub, they seems to cost \$100 a month just to keep them operational
I guess, all the computers, electronics, and my Frankenstein lab are the rest.
