They're the newfangled 'smart meters'.Around here it’s one digital meter. Supposedly the spinning meters aren’t accurate running in reverse. The digital meters only tally up, whether it’s power in or power out. Are yours digital meters?
I do have a second meter, but it’s in my basement next to the inverter. It’s for SREC credits. For ten years you get one credit for every 1,000 KWH produced. They either don’t trust the meter built into the inverter, or they don’t want to deal with different numbers if you change out your inverter? The utility doesn’t own the meter. It’s a revenue grade spinning meter. I read the number and put it into the PJM-EIS Gats system. The credits are sold at market value.
When I first installed the system, one credit was selling for just over $600. I get six credits a year. A few months later the new Governor revamped the system. The market dropped to around $60 a credit. It has been running around $220 for a few years now. I think my credit days are done this September. I sell mine on the Flett exchange.

They require 2 so they can charge retail rates for your usage and get wholesale rates for your generation.
One is the normal meter, the other is connected 'backward' so it reads only what the solar pushes into the grid.
