    Dominion Virginia Power & Excess Generation

    I live in northern Virginia and I'm considering putting solar panels on my house. I understand that Dominion Virginia Power will impose a standby fee on systems over 10 kW AC, so I'm planning to keep my system under that threshold. But even at 10 kW AC, I'll probably be in net-negative territory. Does anyone here have experience with excess generation at Dominion Virginia Power? According to Dominion's net metering terms and conditions, I would have to enter in to a power purchase agreement with Dominion to get paid for my excess generation. It seems simple enough, but are there any pitfalls I should be aware of?

    Thanks,
    Bill

    Over generation may put you in to the category of a generation plant. Not sure of the rules in VA but check very carefully on the insurance regulations regarding this.
    You may be better off to down size the system to meet your needs only.

      Why would you want to be more negative. They will only pay you wholesale rates for any over production which is not likely to be profitable in any way.
      Plus there are a lot more regulations around over production, many companies will not allow any net metering if you over produce by too much.

        Dominion has net metering. Excess power generated will roll over for up to a year. Good change all that extra power will get eaten up in Summer by the AC.
