Solar power in Maine

Solar panels

Solar power in Maine on rooftops can provide 24% of all electricity used in Maine.[1] A 2012 estimate suggests that a typical 5 kW system costing $25,000 before credits and utility savings will pay for itself in 14 years, and generate a profit of $24,683 over the rest of its 25 year life.[2]

Net metering is available to all consumers for up to at least 100 kW generation. Excess generation is rolled over each month but is lost once each year.[3] Maine is given a B for net metering and an A for interconnection.[4]

In October 2007, Maine's largest solar array was the 15.12 kW solar array installed at Maple Hill Farm in Hallowell for $166,000,[5] which through June 11, 2012 has generated 73,416 kWh.[6] Since then average solar costs have dropped substantially, and continue to decline.

In 2011 Maine's largest solar array, 41 kW, was installed on the roof of a new, LEED Platinum grocery store in Augusta.[7][8] A 500 kW system is proposed for otherwise unusable land at the former Loring Air Force Base.[9]

Installed capacity[edit]

Solar insolation in Maine is roughly 33% greater than Germany, the leader in solar installations in 2012.[10]
