Solar power in New Hampshire on rooftops can provide 21% of all electricity used in New Hampshire. A 2012 estimate suggests that a typical 5 kW system costing $25,000 before credits and utility savings will pay for itself in 11 years, and generate a profit of $32,061 over the rest of its 25 year life. 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.
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, giving the state a B for net metering and a D for interconnection. The renewable portfolio standard calls for 10.65% of electricity from renewable energy in 2012, including 0.15% from solar, and 24.8% by 2025, including 0.3% from solar. Noncompliance is used to fund renewable energy, and resulted in payments of $1.3 million in 2009 and $2.6 million in 2010.
In 2005, New Hampshire's largest solar array was the 50 kW solar array 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 solar array installed on the top level of the Manchester Airport parking garage.
In a pilot program, a solar panel was installed on each utility pole, four in Nashua and four in Berlin. The output can be monitored online. 200,000 are being installed in New Jersey.
New Hampshire's average electricity price of 16.47¢/kWh is the sixth highest in the country.
