Excellent service
From start to finish of our solar project for our home, Sunergy was professional and easy to deal with. They took care of everything from scheduling and getting permits to contacting our electric company. Their work was clean and the crew that worked at our home was polite and professional. We would highly recommend Sunergy if you're going solar.

Installation
Solar panels were installed yesterday. Weather was iffy but Brandon made safe decisions for his crew. They adjusted what they needed to do and when the weather improved, they safely did the roof work. All crew members were professional and communication and teamwork was fantastic.

Liars!!!!!!!!!!!!!!!!!!!!!!
I am a senior citizen on a fixed budget and they promised that my bill will be fixed after their calculations, that the meter would be swapped, that I won't have to pay anything extra to electric company and that my wall which they destroyed would be fixed and looking as good as new. Well, guess what! Lies, all lies!!!!!!!!!!!!!!!!!!!!! My wall was not fixed, and no matter how many times I contacted them to get it done it's been 6 months and nothing was done. I am being charges but the solar and by the electric company double of what I was paying before solar and I don't know how to get out of it now. My meter has not been swapped for the solar meter so whatever extra is produced is not going anywhere. My summer bills with the air condition and winter bills were on the average $220 a month and now with solar my bill is close to $300 a month and it's not even summer. And nobody is replying to my emails anymore, nobody know anything and why this is happening, I am just getting a runaround from one person to another. Nothing can be cancelled nothing can be done that's it. they have me by the throat now and nobody gives a shit about lies their sales people, managers, and other numerous executives feeding us when trying to push their solar on to us. LIES LIES AND MORE LIES!!!!!!!!!!!!!!!!!! I email I call and nothing

Best solar companies for home battery installations in Maine
Batteries have become increasingly popular because they take an intermittent energy source like solar and turn it into a reliable and consistent supply of electricity. We recommend getting a solar battery quote if you want a backup power source or if your utility company doesn’t have a net metering program that buys excess solar energy at the full price of power, as you could save a little extra on your electric bill.
Since Maine offers a net billing program instead of net metering, solar homeowners are credited for excess energy at a rate lower than the full retail rate. In this case, having solar energy storage could help you save on your electric bills by using excess power stored to power appliances when necessary. Not to mention, installing a battery gives you backup power in the event of a power outage.
Here are some Maine companies that install panels and solar battery storage systems:

How to find the best solar panel company near you
Picking a solar company is the most important decision you make when going solar. You need to trust them to drill holes in your roof, help you navigate financing and incentives and provide you with 25+ years of customer service.
Check out this video where our founder, who also founded a successful solar installation company, explains what to look for when choosing the best solar company near you.
Top things to consider when choosing a solar company in Maine:
Years in business
One of the first things to look at when finding a company is how long they have been in business. We suggest looking for companies that have been around for at least five years, as the longer it has been in business, the more likely it is you’ll have a positive installation experience.
Companies with five or more years of experience will probably have established after-sales service and warranty support. It signals that they aren’t a company in it to make a quick buck; they’re in it for the long haul.
Of course, there are exceptions to this rule, which is why you should also keep a few other factors in mind.
Licenses, insurance and certifications
Solar companies that are licensed, insured and hold certifications take their business seriously. Look for companies that have NABCEP Certified professionals or certified electricians on staff and are properly insured, so their workers, and you, are protected.
There is no solar-specific licensing for installers in Maine. Solar companies need to have their installers hold a helper's electrician's license and be under direct supervision of a licensed electrician—a license issued by the Electricians' Examining Board.
Financing options
Not everyone has thousands of dollars to spend on a solar panel installation. So, you’ll want to find a company with solar financing options that work for you. Ask for quotes for various types of financing plans to see which one will work best for your budget. Solar loans are often your next best choice if you can’t pay in cash. But, if you don’t pay federal income taxes or can’t qualify for a loan, finding a company that offers solar leases or power purchase agreements might be the right move.
Services and products offered
Don’t choose a company that can’t complete the job that you want to be done. If you need an energy storage system, get quotes from companies that install batteries! Maybe you want a particular brand of panels or an electric vehicle charger installation. Ask the company if they provide those services or carry those brands so you don’t have to settle for less.
Customer review scores
Customer ratings give valuable insight into how a solar company actually operates and treats its customers. Read SolarReviews, Google and Yelp reviews to understand the company’s installation process, sales practices and overall customer service. But remember that some companies incentivize customers to leave positive reviews, so make sure you read reviews with some scrutiny.
Warranty
Any reputable solar installation company will offer a workmanship or labor warranty that covers any damages that may occur during the installation process. We recommend using an installer with at least a ten-year labor warranty.
Some installation companies, like SunPower, include a system performance guarantee. This promises you’ll get a certain amount of electricity from your solar panels and is an excellent added protection.
Maine incentives and rebates
Solar incentives and rebates can cut the cost of installing solar in Maine by thousands of dollars. The most significant incentive is the 30% federal solar tax credit, available to any taxpayer in the country when they purchase solar panels or battery storage.
Some states and utility companies offer additional solar incentives, saving homeowners even more money. Here are the solar incentives available in Maine:
Incentive | Eligibility | Type |
---|---|---|
Residential Clean Energy Tax Credit | Federal | Personal Tax Credit |
Net Metering | State | Net Metering |

What to look for in solar quotes in Maine
Once you’ve found a few companies you like, you can start getting solar quotes. You can get a better deal when you get quotes from multiple solar installers; we suggest getting at least three quotes. Here are a few of my favorite tips and tricks for comparing quotes and what questions you should ask installers.
System size and energy production
All solar quotes should include the size of the system and how much energy it is projected to produce. Most of the quotes you get will probably be in the same ballpark. But, if one is drastically larger or smaller than the others — ask about it! Maybe one installer included shading from a tree, while another based its estimates on having that tree removed.
Maine is the northernmost state in the U.S., so it experiences long, cold winters and mild summers. However, solar panels work just fine in colder climates.
Maine is one of the least sunny states in the country in terms of sun exposure. This doesn't mean you shouldn't get solar here; you might just need more solar panels to cover all of your electric needs. Your solar installer will be able to correctly determine how many solar panels you need in the Pine Tree State.
If you choose reliable installers, you can trust that these estimates will be as accurate as possible. But you can always double-check using the SolarReviews solar calculator and enter the information received in your quotes.
Pricing
You should know as much as possible about how much the solar panels cost. Make sure you know both the total cost of the system and the price per watt of solar installed. The cost per watt makes it easier to compare prices between quotes and gives you a better idea of how fairly the system is priced. The average price of solar is about $2.3 to $3.44 per watt in Maine, so anything in that range is a fair price.
Financing
Financing is one of the most important things to look for in your solar quote. There are a few different things to keep an eye out for, depending on what type of solar financing you’re using.
If you’re looking to use a solar loan, you should ask the company for both a cash quote and the financed quote. Solar loans include something called dealer fees, which can sometimes add 20% or more to the total cost of your system in exchange for a lower interest rate. It’s worth comparing what dealer fees and interest rates you’re quoted from different companies to get the best deal possible.
If you want a solar lease or power purchase agreement (PPA), you’ll want to look for an escalator clause in the contract. The escalator clause outlines how much your payments will go up every year. Ideally, this should be lower than the rate at which electric prices increase in your area, typically about 3% annually. If the escalator rate is higher than this, you could end up paying more than if you hadn’t gone solar at all!
Payback period
Some quotes may include when you’ll break even, meaning when your panels have saved as much as you spent on them. If it’s not explicitly listed on the quote, you can compare any savings estimates they provide to the system’s total price and get a rough estimate of when your panels will pay themselves off. The shorter the payback period, the better.
Equipment
Good quality solar installers will carry good quality equipment. So if you pick an installer you trust, you can expect reliable products. But, it can’t hurt to research and ask the installer questions about what would be going on your roof.
Most solar panels installed today are about 400 watts in size and have efficiency ratings above 19%. Higher wattage and efficiency panels can produce slightly more electricity but may add a price premium. You’ll want to make sure the solar panels have the industry standard 25-year product and performance warranties.
