I haven't all the data entered into a spreadsheet yet, but there are a few limitations I see that make me think going off-grid instead of grid-tied NEM 3.0 is the better path for me, for a Solar + Battery system:
1. There is a mandatory charge based on $8 x PV kW of your solar array. Initially, the charge will be less but it will eventually ramp up to the full charge that must be paid and cannot be offset by the energy you sell to the grid.
2. On average only two hours will have best charge to sell back to the grid, 7pm and 8pm hours of $0.30/kW-h, IIRC.
3. Solar array oversizing is limited to 150% of the size needed based the last 12 mo.'s usage.
4. It remains to be seen what rates the 2 year recalculation will yield, versus the 9 year fixed rates option.
In my case I only used 5112 kW-h in the past 12 months, with an average bill of $100/mo.
Highest month: Aug 2022 659 kW-h, highest day Sep 3, 2022 used 40 kW-h, highest hour Sep 02, 2022 10pm used 8 kW-h.
A 8kW solar array will have me paying $64/mo. at a minimum under NEM 3.0.
I'm thinking off-grid will allow me more freedom, cost less, and potentially reduce my utility bill well below the minimum $64 mo.
