This is what Maine Community Solar looks like...

We’re on a mission to make clean, affordable energy accessible to ALL– not just the select few. Let’s start with you!

Be a part of the solution, not the pollution.

Think of it like this: the farm does the work, and the savings show up on your bill.

We handle the solar.

By subscribing to community solar, you’re increasing demand for renewable energy in your community, directly displacing fossil fuels from the electric grid. That means you can support solar and prevent pollution from fossil fuels without having to install or pay for solar panels.

You see the savings.

Maine electricity customers are guaranteed to save 15% and many can save even more. Get started to see how much you can save each month.

Together, we can make a difference.

Each time you pay your electricity bill, you can feel better knowing your payment is supporting your community’s transition to renewables while also saving you money. By choosing Neighborhood Sun, you’re supporting our work to address energy equity and helping us give back to all of our community partner nonprofits and impact-focused organizations.

Switching to clean energy has never been so accessible (or free)

You subscribe online to a local community solar farm- without any fees or installations.

There are no costs, fees, or installations to subscribe, making clean energy available to renters and homeowners alike. Through our quick online sign-up process, we match you with a solar farm in your community that may already be active or still under construction. Just provide us with a sample utility bill to estimate your share size, and we’ll handle the rest so you can sit back and save!

Your share of the solar farm generates clean energy for you each month.

You continue receiving power through your current utility. Each month, your share of the solar farm adds clean energy to the grid, directly displacing the equivalent amount of dirty energy derived from fossil fuels. This improves local air and water quality and allows you to directly combat fossil fuels just by paying your electric bill.

Your guaranteed savings are reflected as clean energy credits on your current utility bill.

Clean energy is cheaper (and safer) than fossil fuels because the sun shines for free. That means you pay for your share of solar energy at a guaranteed discount (between 5%-30%) compared to your current utility rate. These cost savings will be reflected as clean energy credits reflected on your current electricity bill each month.

Community solar is accessible affordable equitable local easy no-rooftop-needed renter-friendly simple solar.

Local Policy Spotlight:

Maine Community Solar

The Maine Legislature first set the terms for community solar in 2011. Despite being the 43rd ranked state by population, Maine’s Community Solar market had the second largest volume of installations in the country in 2024, behind only New York. In 2025, Maine surpassed other states to reach the highest solar saturation per person, largely thanks to community solar, which accounted for more than half of Maine’s total existing solar capacity by the end of 2025.

Study finds that for every dollar Maine puts into community solar, $1.23 in benefits is returned
53% of solar capacity in Maine is generated by community solar projects
Neighborhood Sun has already passed on $2.6 Million in savings on electricity bills to households across Maine

Central Maine Power Customers

Community solar, also known as Net Energy Billing (NEB), is designed to promote solar access across Maine for people of all income levels. Utility customers subscribe through Neighborhood Sun to a local community solar farm (a.k.a. Community Energy Project). Each month, subscribers see the solar credits generated by their share of the solar farm on their utility bill, reducing the total cost owed to CMP. Then, Neighborhood Sun bills for the solar credits, but with a 15% discount applied, guaranteeing savings.

How does billing work?

Every month, your share of the solar farm earns you energy credits when it generates power. You’ll pay us (Neighborhood Sun) the discounted rate which will automatically be applied to your monthly electric bill through your normal utility provider. For example, if your average monthly bill is $100 a month, and your solar farm discount is 10% off, you will only pay $90 to us and your electric bill will reflect $100 solar credit, nearly zeroing out your electric bill payment to your utility itself.

You may choose automatic debit from a checking account or a credit card. Unfortunately, we do not offer paper billing or non-automated payments. (Hey, it’s better for the planet!)

How do you assign shares to projects?

During your application, you authorize us to review your historical electrical use. We use the past 12-24 months of your electric history to calculate the average amount of kWh you will need each month. Savings are based on the amount of electricity generated by your portion of the solar farm, not your actual kWh use.

How do I save money?

The sum of both bills will be less than your old utility bill. Since we charge less for community solar than what your utility charges for default energy (generated by fossil fuels), you’ll see monthly savings.

Will credits rollover to future months?

Your share of energy generated by the community solar is estimated based on your average monthly energy usage, so some months it may be more or less than the energy you actually end up using. Don’t worry if you use less energy than your share provided because your solar credits will roll forward to the next month without any extra effort on your end. Should you have any rollover credits remaining at the end of your contract period, they will be bought out (repaid) by your utility at that time.

What will credits look like on my electric bill?

When your farm is actively generating clean energy, community solar credits will appear on your current utility bill as “production credits” which reduce the total cost owed to your utility each month. Click on the sample bill below to view an example of the credits on an Xcel bill.
