New Hampshire Solar Information

New Hampshire isn't a bad state for solar but far from the strongest. There is a state tax credit that reduces your income tax. Along with basically wiping out your state income tax although not required by the state the three major utilities servicing all of New Hampshire offer net metering. As always in New Hampshire you are entitled to the 30% federal tax credit.

Solar power in New Hampshire provides a small percentage of the state's electricity. State renewable requirements and declining prices have led to some installations. Photovoltaics on rooftops can provide 53.4% of all electricity used in New Hampshire, from 5,300 MW of solar panels, and 72% of the electricity used in Concord, New Hampshire. A 2016 estimate suggests that a typical 5 kW system costing $25,000 before credits and utility savings will pay for itself in 9 years, and generate a profit of $34,196 over the rest of its 25-year life. A loan or lease provides a net savings each year, including the first year. New Hampshire has a rebate program which pays $0.75/W for residential systems up to 5 kW, for up to 50% of the system cost, up to $3,750. However, New Hampshire's solar installation lagged behind nearby states such as Vermont and New York, which in 2013 had 10 times and 25 times more solar, respectively.

Net metering is available for up to 1 MW generation, but is capped at 50 MW. Excess generation is perpetually rolled over each month, and customers can elect to be paid at avoided cost once a year. The organization Freeing the Grid gave the state a B for net metering and a D for interconnection. The state renewable portfolio standard calls for 25% of electricity from renewable energy in 2025, including 0.3% from solar. Noncompliance fees are used to fund renewable energy, and resulted in payments of $1.3 million in 2009 and $2.6 million in 2010. A 2014 review by the state found the "business-as-usual" model predicted that the state's 2025 goals would not be met.

In 2005, New Hampshire's largest solar array was the 50 kW installation on the roof of the Stonyfield Farm yogurt factory. It remained the largest in the state until PSNH installed a 51 kW array on their roof in 2009. In 2012, New Hampshire's largest solar array was the 525 kW facility on the top level of the Manchester Airport parking garage. It was removed because of glare, and reinstalled with the panels facing East instead of South. Additional panels were installed to maintain the same output.

According to New Hampshire Electric Coop Inc, we received the cost of kWH in your area and calculated energy consumption based on an average electricity bill for 3 months.
I am claiming the 30% Federal Tax Credit (ends 2019) i

When you install your solar system, 30% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is being phased out by 2022.

Most people are eligible to claim this credit (you must owe federal taxes to be eligible).
