Meter runs backwards BUT the bill doesn't

  1. I hoping someone can explain this one to me....

    Background: I have an analog meter from the electrical company still, and it spins backwards all day long on sunny days with my GTI w/5000 watts of solar panels. I live in Massachusetts which gets a mix of rain/cloud/sun and my GTI tells me I generated about 400KWH last month.

    The issue: My bill hasn't changed since installing solar, I normally use about 1000KWH a month, so I expected to see about 600KWH. When I compare the analog meter reading to the bill, it is off by 10KWH and when I called the electric company they said the readings are now electronic even if I have an analog meter and the electronic is what they base the bill off of.

    So I suspect that the analog meter reading is useless and all the energy I'm pumping back into the grid is not being credited to me. Anyone else heard of this electronic meter reading method the power companies use that doesn't reflect correctly on the analog meter attached to the house?

    Look on your electric bill to see if you are being charged for having a solar system. Also, is your system legally registered with the utility? Is your electric bill estimated at times? Like a smart meter their electronic system may not read outgoing power unless you are registered legally. This is how they are getting on top of people using solar if you are not UL compliant and registered. You may have to read up on their regulations too. Just a few thoughts:)
     
  3. I haven't registered it and I suspected they have a 'one-way' meter but didn't know if that was true or not. Massachusetts laws are ridiculous in that only licensed solar installers are allow to do the installations. Just adding to the cost of solar and making it less appealing for people.
     
  4. I'm not an expert, but if that GTI gets hot while it's on than that could be some of the loss. Wire diameter....I use a infrared thermometer for connections. Heat wastes energy, and throws that common core math off. Since they own the meter you need to figure out a differant way to screw them back. I got my own game going on.
