First Month Production Doesn't Match Electric Bill

[Ward L]

POCO Knows All

I'm guessing if you can get your consumption and production from PVOUTPUT.ORG, the POCO has the info too. Few seem to see it, but my recent power bill shows "Consumption". The number is not a net consumption because I made more electricity than I used in the billing period. Given the laws for meeting certain percentage of power by renewable sources, I bet all POCOs know both your power consumption and your power generation.

Ian S has the right answer in post 3.

Net generation as reported by the PoCo and Total production as shown by Enphase are not the same thing. Net generation only shows what you sent to the grid. The 25% difference is what you used straight from the system so it didn't get sent back to the grid.

Conversely, consumption as reported by the PoCo does not include what you used directly from the system. Only what you consumed from the grid. If you add that 25% difference to the comsumption figure you will get the total you used during the time period.

Totally agree. This is how it works for me.

Unless they install a meter between your array and your electric panel how will they know? Or is it a magic green thing?

You need to read more. Net metering (single meter from SCE) only record what you send and receive from grid. During solar prodution, you only send to grid surplus after your own comsumption. Why is it so hard to understand?

PVOutput.org doesnt know anything about your system, because people upload and share their data there.

In states where there's a production-based incentive they do put a meter between the array and the panel. So that's not an uncommon thing.

How many states have that? You are looking for the needle in the haystack.

Maybe so, but since the state I happen to live in does exactly this, I don't have to look very hard.

IIRC, the east-coast states with SRECs also will attach a production meter to measure the production for the SRECs. Maybe someone who lives in MA, PA, NJ, OH, MD or DE can chime in on whether they have a production meter.

In Arizona, APS required a separate production meter to be installed for my system.

I could call my installer too and ask them if they measure my production and consumption separately. I agree that the consumption on my bill is likely the amount I used when my panels were dark.
