Hi,
Looking for advice here on adding additional solar and switching from a smaller NEM 1.0 setup to a larger 2.0 setup.
Background:
I currently have a grid-tied 10kW system on NEM 1.0. I end up still requiring about 10,000 kWh from the grid a year costing me about $3,000/year on true-up billing. I'm currently on a tiered rate plan as allowed under NEM 1.0.
Proposal:
I'm debating adding extra solar. If I add another 12kW system for an extra 16,500 kWh production (80% safety factor for required + 3,000 kWh a year for another EV 10k mi/yr) cost is about $31,000. But it will require me to switch to NEM 2.0 and go from tiered to TOU with non-bypassable charges.
Questions for anyone able to tackle:
-would it make sense to add a second meter and have a split NEM 1.0/2.0 setup to save on NBCs?
-what is the likely impact of switching to NEM 2.0? As I don't have a smart meter, I don't know how many kWh I'm consuming from the grid or how many kWh during peak hours.
-At the time I installed the panels, conventional thinking was to undersize the PV system for maximum ROI. I was counting on the cost for PV to go down but it didn't work out that way. Now several years later, in retrospect I should have over-sized my NEM 1.0 setup.
-I'd like to insulate myself from more price hikes down the road. I suspect the cost per kWh to go up over time, and the TOU peak periods to expand from 4-9pm to 4 to 11pm and beyond, and the base monthly fee to increase even under NEM 2.0.
-Is there any benefit of Powerwalls if backup is not a concern when on NEM 2.0? The ROI seems like it would take forever.
