Connecticut is one of the fastest-growing small states investing in solar energy.* Since the state launched the Connecticut Property Assessed Clean Energy (C-PACE) program to make solar more affordable, more homeowners have been switching to solar power to reduce their environmental impact and save money on electricity bills.
We analyzed websites, warranties, customer reviews, pricing, and more to determine the best solar companies nationwide. Then, we narrowed down our list to the five we recommend for Connecticut residents.

Top Solar Installation Companies
We recommend looking into these solar providers:
- Most Experienced: SunPower
- Best Comprehensive Coverage: ADT Solar
- Best for Home Builders: Sunrun
- Best for Guided Services: Momentum Solar
- Best Aesthetic: Tesla
Most Experienced: SunPower
SunPower has more than 35 years of solar experience, making it one of the most knowledgeable leaders in the industry. Customers compliment the provider’s prompt and helpful service in reviews. Its panels are among the most energy-efficient on the market, averaging about 0.8% higher than typical efficiency ratings.
Best Comprehensive Coverage: ADT Solar
Rest assured that you’ll be taken care of for many years to come with ADT Solar. The company provides 25 years of warranty coverage for all panels, inverters, and workmanship. Customers also get a 25-year power production guarantee that promises a certain level of panel performance.
Best for Home Builders: Sunrun Solar
Sunrun’s BuilderChoice New Homes Program makes it easy to install a solar energy system while building a new home. The program works with your existing roofers and provides a dedicated team that handles all paperwork for code compliance, permitting, and connecting relevant utilities. Sunrun also provides multiple financing options, including an up-front cash purchase, solar loan, solar lease, and power purchase agreement (PPA).
Best for Guided Services: Momentum Solar
Momentum Solar handles every aspect of solar installation in-house and offers a variety of panels from different manufacturers. The company’s mobile app and frequently updated blog provides customers with ongoing service and education on solar energy use.
Best Aesthetic: Tesla
Solar panels help you save money and reduce your impact on the environment, but not all homeowners love the look of raised panels on their roofs. Tesla sells solar panels and solar shingles that are designed to lay flat against your existing roof. They blend in to look like a regular roof while still providing solar benefits.
Solar Installation Cost Factors in Connecticut
The average cost of a solar system in Connecticut is roughly $20,500, which is within the national average.* The following factors impact this price:
- Company: Solar companies price their products and services differently. Whether they do the work in-house or outsource it plays a big role in pricing.
- Energy efficiency: Expect to pay more for high-efficiency panels.
- Location: Costs vary by city and state. Solar incentives also vary by location, though these can lower your costs.
- Panel type: Homeowners can choose between monocrystalline, polycrystalline, and thin-film panels. Monocrystalline panels are recommended for residential solar panel systems because they’re the most efficient, but they’re also the most expensive.
- Roof pitch: Plan to pay more if you have a particularly steep or complicated roof that makes installation more dangerous or difficult for laborers.
- System size: More panels equal a higher price.

Solar Tax Incentives in Connecticut

- Renewable Energy Systems Tax Exemptions: Connecticut homeowners get tax breaks for going solar. The Sales and Use Tax Exemption for Solar and Geothermal Systems exempts homeowners from paying any taxes on the purchase of a system. The Property Tax Exemption for Renewable Energy Systems exempts homeowners from paying additional taxes on the increased value of their homes due to installing solar panels.
- Net-metering: You can make extra money by selling extra energy your system generates to your local utility company.
- Federal Solar Tax Credit: This federal program allows you to claim 30% of your total system costs on your taxes if you purchase your system outright or through a solar loan.

What to Ask Solar Providers
Don’t sign a contract with just any solar company. Take the time to vet the company and ensure it is qualified to do a great job.
We recommend asking solar panel companies these questions:
- How long have you worked in solar?
- How many systems have you installed? May I see photos?
- Are you NABCEP-certified, licensed, bonded, and insured?
- What is your business license number?
- Can you share a few customer references?
- Have you worked with my local utility company?
- Does your team do all the work, or do you use subcontractors? How do you quality-check the work your subcontractors perform?
- Who do I contact if I have a question or issue? What are turnaround times like to resolve issues?
We also suggest asking these questions about their equipment:
- What are the benefits and drawbacks of this equipment?
- Is this what you have/would put on your home or business?
- What warranty protection is offered for each piece of equipment?
- What do customers complain about with this equipment?
Solar providers often provide a few services to help guide you through the solar process and care for your system after installation. These can include the following services:
- Consultation: All companies should offer an initial consultation to discuss your home’s energy needs and whether your property is a good fit for solar. This can often be done virtually or in person. While virtual consultations are more convenient, be aware that the representative won’t be able to provide as specific or potentially accurate information as they would if they saw your property in person.
- Design: Providers have in-house design teams to create the best solar panel layout for your roof. You’ll approve this design before installation moves forward.
- Installation: Not all companies use an in-house installation team. Some use third-party companies. Some only install panels, while others also install batteries, electric vehicle chargers, and other equipment.
- Maintenance and cleaning: Many warranties include some sort of maintenance plan through your provider for a period of time. Check to see if a company provides any maintenance or cleaning services after installation.
- System monitoring: If a company has a mobile app, it likely includes some degree of system monitoring. Check if a provider offers system monitoring to track your panels’ performance.
- Additional services: Some companies partner with third parties to handle services that help your installation run smoothly. Roof repair and pest control are common additional services, as it isn’t wise to install panels on a damaged or infested roof.
Every company on our list has something to offer. Consider your top priority to pick the right company for you. If that’s expertise, SunPower has been in business for more than 35 years and is considered an industry pioneer. If it’s guaranteed protection, ADT Solar has a 25-year warranty and power production guarantee. If you’re building a new-construction home, consider how Sunrun can simplify the solar process by working alongside your builders.
We recommend getting a solar quote from at least three companies before deciding. You should also read customer reviews and talk to providers about their warranty coverage and installation process.
What Solar Installation Looks Like
Most solar companies walk you through these steps:
- Site evaluation: An installer will visit your home to confirm the planned design and estimate the scope of work. This person or their team will also inspect your roof, attic, and electrical setup.
- Permit approval: Most states require a permit to install solar panels. Your solar provider should handle the paperwork with your local municipality.
- Installation: Installation typically takes one to three days. You don’t need to be home for it, but we recommend it so you can ask questions along the way.
- Cleanup: Installers should remove any debris and leave your property in good condition.
- City inspection: Your provider should coordinate with your city to have an inspector come out to check that your system is up to code.
- Utility connection: Your system must be connected to your local utility system if you’re connecting it to the grid. You’ll apply for connection through your utility company (some providers do this for you). Your utility company will also want to inspect your system to make sure it’s in accordance with its utility guidelines. After getting permission to operate, your system can be turned on.
