Solar power in Maine
Last fact-checked on January 19, 2023, by Catherine Lane
Maine has some room for improvement when it comes to incentivizing solar for homeowners. Although there are no statewide or utility incentives available, the state does have a renewable portfolio standard (RPS) and a law in place that requires utilities to offer net metering.
Net metering combined with the 26% federal tax credit makes solar a sound investment for Maine homeowners.

What are the pros and cons of installing solar panels in Maine?
The advantage of installing solar panels in Maine is the mandatory net metering law. Maine has high electricity rates, which means homeowners will save big on their utility bills, thanks to net metering.
The disadvantage of installing solar panels in Maine is that there is very little in the way of state and utility-based incentives. Also, Maine receives less sunshine than other states, so a solar system here will produce less than a solar system in a sunnier state, such as Arizona.

What rebates, solar tax credits, and other solar incentives are available in Maine?
Net metering in Maine
Solar, by its nature, generates the most power during the middle of the day when most people are at work or school and little power is being used in the home. The net metering policy in Maine mandates that for every surplus kilowatt hour (kWh) generated by solar (like the excess energy your system creates during the day) utilities must provide a credit equal to the average cost rate of energy per kWh.
Maine legislatures have been battling over a net metering policy for a few years. Just recently, full net metering was brought back for solar customers.
The best time to go solar is now while state policy still mandates that each kWh is credited at the retail rate.
Renewable portfolio standard
Maine has a renewable portfolio standard (RPS) that establishes renewable energy goals for the state’s utilities to meet. The RPS states that by 2017 and each year after, 30% of Maine’s electricity must be derived from existing renewable generation systems and 10% of Maine’s electricity load must come from new renewable resources. Total, the state must receive 40% of its energy from renewable resources.
