Are you on a TOU plan ? If so, I'll guess that part (perhaps most) of the reason you ended up with a small credit is TOU savings. The utility is paying you to shift consumption and it let's you arbitrage your solar production.ttweed wrote:philip wrote:
It sounds like with your over-production, you will owe the minimum charges, as you would need to purchase at least $120/year in energy to have them all refunded. If you overproduce (energy not dollars), then the approximate $.04/kWh production credit would offset minimum charges, however this isn't a cost effective use of an expensive PV system.
Well, this month was my 1-year account true-up with SDG&E. I ended up with an $8.80 credit. Net generation credits and CA Climate Credit completely cancelled out the $120 minimum charge adjustment, and gave me a net negative bill for the year. I'm a happy camper. I would have paid probably $1500-2000 for the year without solar, and my amortized cost of the system was $650 (plus maybe $250 in lost opportunity cost from paying $13K up front). It looks like free money from the sky to me.
As it should be!
