Summary of Maine solar incentives 2024

Maine saw a big win for home solar in 2019, with new governor Janet Mills reversing the “gross metering” policy of outgoing dumpster fire Paul LePage, and reinstating net metering for all Mainers.

That means your utility company now has to give you full credit for the solar power you send back to them which you can’t use onsite. That’s the kind of change the state’s voters asked for in 2018, and they got it!

Read on to see how that change impacts your home savings estimates for going solar in Maine!

On this page, you can:

Federal tax credit Net metering Solar rebates Cost of solar panels in ME

Federal solar investment tax credit

The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in Maine

If you install your photovoltaic system before the end of 2032, the federal tax credit is 30% of the cost of your solar panel system. This is 30% off the entire cost of the system including equipment, labor, and permitting.

Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 30% = $6,000.

The federal tax credit falls to 26% starting in 2033.

Net energy metering in Maine

With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.

Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume to make sure you get credit for the surplus.

With kudos to governor Janet Mills, Maine has re-established 1-to-1 net metering credits at full retail for solar home solar energy. However, if you have unused net metering credits at the end of the year, they get reset to zero and cannot be credited toward your January bill from December.

Therefore, it’s important to size your home solar system well, to ensure you aren’t running over and unable to use credits after the year is up. Connect with a local solar expert to help get your system sized well and calculate your savings.

Maine solar rebates

While Maine does not have a dedicated state rebate for solar panel installation, some manufacturers like LG offer their own solar rebates. These programs are usually time sensitive. For example, LG offers a $600 solar rebate on their equipment, which your installer can help you redeem over the next year.

Sunergy made it super smooth and easy to get solar. We had need of a large system to sustain a lot of computing, EV usage, and heatpump, so ended up drafting out a 12.75kW array. Their representative John Parlator kept in close contact through the whole process, from design to aftersale support, making sure that all of our needs are met. Very happy to have chosen Sunergy.

Overall, we are happy with the service as so far there isn’t any issues yet since we just started last year. I do want to give a big shoutout to Rachel, who always goes above and beyond! Even my inquiries aren’t in the area she handles, she always tries to find an answer and gives us the update.

Janet H., over 1 month

From start to finish this was an exceptional process. It was a throwback to a time when customer service was all about the customer. We were kept informed every step of the way, called if there was a delay for any reason, work was done timely, staff were more than competent and I was completely comfortable having them in and on my home. The work area was always cleaned before they left for the day. It was so refreshing to work with a company that does quality work, with quality products and cares about the client experience from start to finish.

We would recommend Maine Solar Solutions enthusiastically! Steve Kilborn worked with us to create an array that fit our roof and needs and was affordable. Though Steve initially told us our panels would be installed in early May, they had them in place by April 1. The crew that did the installation was exceptionally polite and considerate. Adrian--the crew chief--communicated with us so we knew when to expect them, and he kept us apprised of the process throughout. The electrician, Noah, helped us restore internet when the work inadvertently caused us to lose it, and he provided us with a very thorough explanation of the system and how it would world work. He answered all of our questions clearly. The crew installed the panels on a metal roof, but did so carefully, and it looks great!

It's so nice to deal with a company that is truly customer focused. I live in home owned by an extended family- all of whom had many questions about a potential solar project. Their questions were patiently answered. The installation process was efficient and careful - which is not always the case when service people encounter our nearly two hundred year old Victorian home. Since the panels have been up and running we've only encountered one minor software problem, and Andy Robitaille emailed me about it before I even had time to contact him! I'm VERY satisfied with our system and the service we've received from this company.

This is who you want to do business with. When you work and meet with Daryl, his integrity and knowledge will ease any anxiety you might have over what is (perhaps) a large financial decision. His product outperformed other panels offered by similar companies. The craftmanship upon installation was excellent. But most important was the piece of mind knowing I was working with a committed, trustworthy, responsible, individual.
