Solar Panel Cost in New Hampshire (2026)

Net metering: Net Metering 2.0 - partial retail credit

New Hampshire credits exported solar generation under the framework generally called Net Metering 2.0, and the important thing to understand is that it is not a one-to-one retail credit. A New Hampshire electricity bill separates supply, transmission and distribution. The export credit pays 100 percent of the supply charge, 100 percent of the transmission charge, and 25 percent of the distribution charge, which lands at roughly 75 to 95 percent of the full retail rate depending on which utility serves you and how its charges are split. Electricity your household consumes at the moment it is generated is a different matter: that displaces the whole retail price, because you simply do not buy it. So exports are worth somewhat less than self-consumption rather than dramatically less, which puts New Hampshire in a middle position between the states that kept full retail net metering and those that moved to avoided cost. The practical consequences are modest but real. Load shifting into daylight is worth doing, storage has a small economic argument on top of its resilience case, and a system generating a large annual surplus is converting full-value electricity into partial-value credit. Build from your last twelve months of bills and ask what percentage of your annual usage the design covers.
