We still have net metering here in NH, but the utilities have just negotiated a drop in the net credit…used to be 1:1 for both energy supply and distribution, now 100% for supply and 25% for distribution. The impact varies by utility, from about 2% to 20% less credit. There are also system size (quite large…doesn’t bother residential0 limits and caps on how much net metering each utility/area can produce…if you get in late, you may get zero.
In NH, as for so many other states, net metering is under attack by the utilities, less of an advantage all the time, and going away in the future…utilities HATE it.
Unfortunately, battery systems add a HUGE cost to the solar system…my 6.2 year payback would have become more than 11 years and I doubt I’d have done solar at all. The Tesla system to capture my daily excess solar production in peak months would have added a whopping $15,000 to my fairly modest system, none of which would have been covered by the federal and state rebates.
