That makes sense, since it still doesn’t show as NEM2PS in my services section and no B&W. I assume this will update in 1-2mo.I had not seen this version of a bill before, thanks for publishing it. This looks like a solar only NEM2 bill.
I think the only factor added by storage is the limitation of NEM credits only to the amount of estimated solar production. The estimate is based on theoretical production for your system, based on panel count, orientation, inverter efficiency and sun position for each month. I'm not sure what it does about weather, but in my experience the estimate is far above actual exports.
I was if the impression that the max export was pretty close to the PVWatts modeling. Can anyone confirm?
This is due to a substantial amount of our solar being consumed rather than exported. If and when they get you the detailed bill, the export credit probably will not be a problem.
I thought it became an issue if you export solar during day at off peak and part peak + have many PW’s and do TOU arbitrage during peak. Which is kinda my case.
Ok, yes. But if I can generate lots of credits in summer and even fall at peak (TOU arbitrage with PW) then shouldn’t I be able to offset winter net consumption? I’ll anyways ensure that I never import at peak in winter just by having enough PW capacity.In addition to that, the detailed bill will show how your payments get accounted for across the various bundled rate categories, but this is only for their internal account. Hence the 16 pages...
Durning summer months with high solar production, NBC's dominate because the NEM charges are small or negative. But durning winter, your NEM charges will probably be positive, and considerably larger than the NBCs, so your turn-up will probably be based on NEM rather than NBCs. In either case, the monthly minimums will have already been paid, so that amount will be subtracted from the NEM or NBC basis to arrive at the true-up adjustment which you will owe on that true-up bill.
