What Is Net Metering 2.0? New Hampshire’s Solar Compensation Framework
Net Metering 2.0 is the current regulatory framework in New Hampshire that determines how residential and commercial solar owners are credited for the excess electricity they export to the utility grid. Under this "Alternative Net Metering Tariff," customers receive a monetary credit on their utility bill for surplus energy, typically calculated at 100% of the transmission and distribution rates plus 25% of the default energy service rate.
Established by the New Hampshire Public Utilities Commission (PUC), this policy shifted the state away from "1-to-1" traditional net metering to a more complex credit structure designed to balance grid maintenance costs with renewable energy incentives. According to data from the New Hampshire Department of Energy in 2026, this transition remains a foundational element for the state's goal of reaching 25% renewable energy generation. Understanding these rates is essential for homeowners calculating their long-term savings and system sizing.
For New England residents, Net Metering 2.0 represents a middle ground between aggressive solar subsidies and utility cost recovery. While it offers slightly lower export credits than the original 1.0 version, it remains one of the most robust solar incentives in the Northeast. Boston Solar has helped over 6,000 customers navigate these evolving regulations, ensuring that systems are engineered to maximize self-consumption and optimize the value of every kilowatt-hour produced.
Key Characteristics of Net Metering 2.0
- Variable Credit Rates: Credits are split into components, usually covering full transmission and distribution costs but only a portion of the supply/energy cost.
- Monthly Rollover: If your solar array produces more energy than you consume in a month, the dollar-denominated credits roll over to the next billing cycle indefinitely.
- Annual Payout Options: Once a year, customers with accumulated credits may request a check from the utility, though this is often at a lower "avoided cost" rate than the standard billing credit.
- Grid Access Fees: Unlike earlier iterations, 2.0 may include modest non-bypassable charges that ensure all customers contribute to the upkeep of the physical electrical grid.
How Does Net Metering 2.0 Work?
The process begins when your solar panels generate electricity during daylight hours. This energy first powers your home's active appliances; any surplus flows through a bi-directional meter back to the utility grid. The utility tracks this export and applies a credit to your account based on the current PUC-approved rates for your specific utility provider, such as Eversource or Liberty Utilities.
During the night or on cloudy days when your panels aren't producing, you pull electricity from the grid as usual. At the end of the billing cycle, the utility subtracts your earned credits from the cost of the energy you consumed. If your credits exceed your consumption, the balance remains on your account as a financial cushion for high-usage months, such as the winter heating season.
Common Misconceptions About New Hampshire Solar
| Myth | Reality |
|---|---|
| Solar is no longer profitable under 2.0. | While the export rate is lower than 1.0, rising utility costs in 2026 make the avoided cost of "self-consumption" more valuable than ever. |
| You lose your credits at the end of the year. | Credits roll over month-to-month; you only lose the "premium" value if you opt for a cash payout instead of a bill credit. |
| Net Metering 2.0 requires a battery. | A battery is not required, but it does help you avoid "selling" power at the 2.0 rate by storing it for your own use later. |
How Does Net Metering 2.0 Affect Solar Payback Periods?
The transition to Net Metering 2.0 has slightly extended the average solar payback period in New Hampshire compared to the original 1-to-1 rules. In 2026, a typical residential system sees a simple payback period of 7 to 9 years, depending on the specific utility territory and the homeowner's ability to use solar power in real-time. Because you are credited less for exported power than you pay for imported power, "load shifting"—using heavy appliances during the day—becomes a critical strategy for ROI.
According to recent market analysis, the internal rate of return (IRR) for New Hampshire solar projects remains strong at approximately 10-12% [1]. To combat the slightly lower export rates, many homeowners are turning to battery storage solutions like the Tesla Powerwall. By storing excess energy instead of exporting it, users can "self-consume" their solar power during expensive peak evening hours, effectively bypassing the 2.0 credit reduction and shortening the payback window.
Net Metering 1.0 vs. Net Metering 2.0
The primary difference between the two versions lies in the valuation of the "Energy Service" or supply component of the bill. Under Net Metering 1.0, customers received a 1:1 credit for every kilowatt-hour (kWh) exported, meaning the credit value equaled the retail price of electricity. Net Metering 2.0 reduced the supply portion of that credit to 25%, though it preserved 100% of the transmission and distribution credits. This change was implemented to ensure solar owners still contribute to the fixed costs of maintaining the poles and wires that they rely on for grid stability.
Why Is System Sizing Critical Under Net Metering 2.0?
Under the 2.0 framework, "over-sizing" a solar array beyond your annual consumption yields diminishing returns. Since exported energy is compensated at a lower rate than what you save by using the energy yourself, the most financially efficient systems are those designed to cover roughly 100% of annual usage. Boston Solar utilizes advanced shading analysis and production modeling to ensure customers don't over-invest in panels that primarily produce low-value export credits.

Frequently Asked Questions
What is the average solar payback period in New Hampshire in 2026?
The payback period for solar in New Hampshire typically ranges from 7 to 9 years under Net Metering 2.0. This timeline is influenced by your utility’s specific rates, the total cost of your installation, and how much of your solar energy you consume directly versus exporting to the grid.
Can I still get the federal tax credit with Net Metering 2.0?
Yes, New Hampshire solar owners are still eligible for the federal Residential Clean Energy Credit, which allows you to deduct 30% of your solar installation costs from your federal taxes. Combining this with Net Metering 2.0 credits significantly improves the return on investment.
Do I need a battery storage system under Net Metering 2.0?
While not required, a battery allows you to store excess solar energy and use it at night. This is beneficial under Net Metering 2.0 because ‘self-consuming’ your power is more valuable than exporting it to the grid at the reduced 2.0 credit rate.
