Great company, highly recommended!
After a horrible experience with a different company, I chose Green Power Energy to design and install a solar energy system on my roof. They were a great company to work with. They are knowledgeable, professional, and listen to their customers in order to design the right system for them. The design, permitting, interconnection, and installation process all went smooth without any issues. The installation team did a great job; they were professional, easy to work with, and installed the whole 25 panel system in 1 day. As an engineer and building science hobbyist, I am very informed on solar energy design principles, building code and practices, and have the appropriate background to see that Green Power Energy is paying attention to the details and doing a great job. I would highly recommend them.

Mixed experience
Their prices are competitive, but they overshot their installation and approvals deadlines by 7 months. The contract was signed in oct 2022, they didn’t do the design work until January. And installation didn’t happen until February 2023. I can understand that they were short staffed and behind, but even after that, it took repeated reminders from me to get them to submit the appropriate approval requests, constant follow ups, dealing with failed inspections, and now in June we got approvals, but it will take another month to coordinate the activation of the panels. I get that towns and Eversource are slow for their approvals, but I have friends who went with Sunrun at the same time last Oct and were activated by March 2023. Do these larger companies get a higher priority with the towns and Eversource?maybe, but more diligence from them could have shorten this duration.

Horrible service
I have been trying for the past 2 years to solve my issues with state inspection and still have not passed the state inspection. I have called and left massages and no one follows up and I never got anything that I was offered at presentation. Very disappointed with this company.

TE | Taunton, MA | 03-21-2025
I have had a great experience with a tech - Ronald Donnelly who stopped by while checking in on folks who had solar in the neighborhood. He listened to me when I said I had noticed an issue with my National Grid bill and not seeming to be getting the correct credits for my system. Log story he short - he saw that the second system we had installed for our addition was not set up correctly within the billing/crediting system. He did a little digging and found that I needed to fill out a form for National Grid to correct it. I have submitted the form and we're working to get things straightened out. He was so friendly and supportive. He checks in to see how things are going as we work through the process.

False promise of savings
I signed an agreement believing their solar service would reduce my electricity costs with a fixed rate. Instead, the system was under-designed, failing to generate enough power for my needs, forcing me to buy additional electricity from my utility, increasing my total costs by 40%. Do not believe ANYTHING their salesmen tells you.

Best solar companies for home battery installations in Stamford
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.
Here are some Stamford 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 Stamford:
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.
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.
Stamford incentives and rebates
Solar incentives and rebates can cut the cost of installing solar in Stamford 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 cities, counties, states and utility companies offer additional solar incentives, saving homeowners even more money. Here are the solar incentives available in Stamford:
| Incentive | Eligibility | Type |
|---|---|---|
| Residential Clean Energy Tax Credit | Federal | Personal Tax Credit |
| Residential Renewable Energy Solutions Program | State | Net Metering |
| Sales and Use Tax Exemption for Solar and Geothermal Systems | State | Sales Tax Incentive |
| Property tax Exemption for Renewable Energy Systems | State | Property Tax Incentive |
| Smart-E Loans | State | Loan Program |

What to look for in solar quotes in Stamford
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.
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 $2.29 to $3.43 per watt in Stamford, 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.
