- It's pretty common, and it's a lot simpler, since you don't have to deal with batteries.
The other way to go is to have appliances that run directly off the DC generated by the panels, but that's for real off-the-grid types, which I am not.Jun 14, 2012
- I thought you just needed an inverter?Jun 14, 2012
- I'm not an expert at all, but my vague understanding is that, sure, you need an inverter, but you need to feed the power into something.Jun 14, 2012
- thank you very much for the info ... looks like it's not as big saver as I thought for small households.Jun 14, 2012
- Yeah, even in California, sunlight isn't constant so you need some kind of storage, and batteries don't scale well. The two big wins are that you're most likely offsetting carbon based dynamic production, rather than "base" cleaner sources, and the whole awareness of consumption that comes from deploying a system and telling your friends about it:-)
(BITD the other trick was dynamic pricing, where you sold power high during the day to meet consumer air conditioning demands, then bought it back low at night to charge your EV1; with plugin hybrids that might be viable again...)Jun 14, 2012
- Yes, we will do the dynamic pricing thing. That factors into the 8 to 9 year payback. It works out nicely under the current rules, though PG&E is trying to change them.
We're on the list for a Tesla Model S, probably early next year, assuming we like it when we can do a test drive.Jun 14, 2012
