Best Solar Companies in Connecticut
Getting a solar installation is not a one-off process. Residential solar energy systems are built to last for decades, and good solar companies often have warranties in place to guarantee that any issues or faulty parts that crop up over the years get fixed. That’s why it’s important to start off on the right foot and find a reputable company who you’ll be comfortable working with in the long term. Here are eight of Connecticut’s most popular solar companies, including one which we think stands out compared to their peers.
Earthlight Technologies is a family-owned solar company based out of Connecticut. They work exclusively with the major US solar manufacturer Sunpower to install reliable and high-performing solar energy systems for their customers.
Earthlight Technologies is headquartered in Ellington, Connecticut, but the company also has separate office locations in Oregon and Massachusetts. They serve customers throughout all three of these states.
Licensing and Certification
Earthlight Technologies holds the required Home Improvement Contractor license for Connecticut. They also hold a Master Electrician license for the state. This allows them to install solar panels and connect them to your home electrical wiring directly without requiring the help of sub-contractors, unlike solar companies with only a Home Improvement Contractor license.
The company also employs NABCEP-certified PV Installation Professionals. They are the only Connecticut-based Sunpower Master Dealer.
Founded in 2008, Earthlight Technologies carries out both residential and commercial solar installations across the states of Connecticut, Massachusetts and Oregon. Its CEO and founder Timothy Schneider is a licensed electrician himself, and boasts over 30 years of experience running electrical contracting companies. In addition to installing solar, Earthlight can also help with commercial energy efficiency contracting work, renovating business locations to lower their energy use.
The company only uses high-performing Sunpower equipment for their solar installations, which carry a 25-year manufacturer’s warranty.
Earth Technologies has received very favorable online reviews on both Google and Facebook. The company holds a 4.8-star rating on both platforms, out of a total of 83 reviews on Google and 20 on Facebook. They’re also accredited on the BBB, and have an A+ rating from the site.
They also have a good, but slightly less impressive rating on Solar Reviews, where the company has a 4.19-rating from 19 reviewers. While almost all of their customers were satisfied with the quality of their installed solar energy systems, two reviews mentioned that Earth Technologies should be doing more to keep customers informed of how things were progressing during the installation process.
Trinity Solar is a large multi-state solar company, with more than 1,600 current employees and over 65,000 completed installations across its 27-year history. The company puts a keen emphasis on offering attentive customer service and delivering individualized solar solutions to each customer.

Trinity Solar has also racked up 72 complaints on the BBB, partly due to the size of the company. Only 22 of these complaints have been resolved, though all recent complaints have been answered.

We believe Earthlight Technologies to be the most reliable solar company on our Connecticut list. Like many other companies operating in the American Northeast, they exclusively install premium Sunpower Equinox solar energy systems. However, Earthlight is the only installer headquartered in Connecticut which has been invited by Sunpower to become one of its Master Dealers. There are only a total of 25 Sunpower Master Dealers in the country, despite the many solar companies carrying their products, and Sunpower puts each Master Dealer through a rigorous certification process to make sure that their installation quality is up to the task of representing its brand.
Earthlight Technologies also employs a full team of state-licensed, NABCEP-certified electricians. Unlike a few other solar companies lacking an electrical license, this means that Earthlight is fully capable of carrying out all solar work without the help of an electrical sub-contractor. While sub-contracting is common in the industry, and does not necessarily lead to poor installations, doing everything in-house affords solar companies more quality control over their work. When you run into an issue, there’s also no risk of being ping-ponged between your solar contractor and electrical contractor, as each side tries to avoid taking responsibility for your problem.
Solar Power in Connecticut
Connecticut is firmly middle of the pack when it comes to installed solar power capacity, coming in 21st out of all US states. This statistic is deceptive when it comes to residential solar, however: many other US states see the majority of their solar power capacity come from large-scale solar utility farms, but Connecticut’s residential solar growth has outpaced that of large-scale utilities since 2012. In fact, an incredible 75% of all solar power generated in Connecticut come from residential sources!
This growth has partly come about due to Connecticut’s very high electricity costs. State residents pay the most for electricity in Connecticut compared to any other state apart from Hawaii. This also means that solar power in Connecticut has great potential for generating huge savings on your utility bills. More than 19,000 Connecticut homes have already installed solar power, and the government-run Connecticut Green Bank estimates that going solar can help local households save an average of $11,000 in utility bills. Here’s a closer look at the laws, incentives and net metering options available to Connecticut residents.
Laws and Regulations
Connecticut was one of the first US states to pass a formal set of Renewable Portfolio Standards (RPS) into law in 1998, which are regulations mandating state utilities to source a minimum portion of their electricity from renewable sources. The requirements have been continuously updated over the years, and right now Connecticut requires all investor-owned and local government utilities to use 48% renewable energy by 2030. In addition, the majority of this renewable energy has to be generated from Class 1 sources, which includes solar and wind power.
When it comes to the rights of homeowners for installing solar, however, Connecticut falls behind many other states. Connecticut has no formal solar easement laws, which are laws that prevent homeowner associations from forbidding solar installations on residential property. Homeowners also do not have a “right to sunlight”, which means owners of neighboring property are allowed to carry out property renovations that reduce the amount of sunlight that your house receives.
Connecticut does issue specific solar contracting licenses, namely the PV-1 and PV-2 Limited Solar Electric Contractor and Journeyman licenses. However, these licenses only allow the contractor to perform work strictly related to the solar energy system itself. A further Electrical Contractor license is needed to connect this system to the electrical wiring of a property. Since an Electrical Contractor license on its own also allows a Connecticut contractor to install solar energy, many solar companies in the state forego a specific Solar Electric license in favor of simply obtaining an Electrical Contractor license.
In addition to this Electrical license, a Home Improvement Contractor license is also required for any contractor doing paid work on residential properties, which includes solar installation. Some solar companies in the state may only possess this Home Improvement Contractor license without an Electrical license. This still gives them the legal ability to sell solar installation services to homeowners, but they must subcontract the required electrical work to another company with a valid Electrical license.
In addition to these required state licenses, some solar companies also employ NABCEP-certified PV Professionals. These are solar technicians and electricians who have received certification by the North American Board of Certified Energy Practitioners after either showing proof of their solar industry experience, or passing a rigorous examination. These certificates are highly regarded in the industry, and we recommend going with a solar company who’s employees have been certified.
Connecticut’s net metering rules received a major overhaul in early 2021, following new plans brought forward and passed by the state’s Public Utilities Regulatory Authority. Currently, residential solar owners in the state are able to sell back their excess generated electricity to the grid at full retail rates measured in kilowatt-hours. These kilowatt-hours are rolled over at the end of each month to offset future electricity consumption. At the end of the billing year, any leftover kilowatt-hours are credited to the homeowner in cash, but at lower avoided-cost rates instead of full retail rates.
The new net metering rules, set to take effect from 2022 onwards, gives customers a choice between two net metering plans. They can choose to stay on the original plan described above, which remains unchanged except that excess credits are rolled over indefinitely instead of turned into cash at the end of the year. Or, they can participate in a buy-all/sell-all tariff plan, where the customer sells all solar power generated back to the grid at a fixed tariff rate, decided in the year that their solar energy system connects to the grid and fixed for 20 years. They then purchase the electricity they use from the grid normally at retail rates.
Tax Credits and Incentives
Connecticut’s Green Bank Residential Solar Investment Program (RSIP) provides a direct rebate of $0.358 per watt of solar installed up to 10kW, and $0.207 for each watt between 10 and 20kW. To be eligible, your home needs to be connected to the Eversource or UI utilities, and the property needs to be a “good” location for a solar installation. This program is currently capped at 382 MW, and is set to expire after the limit has been reached.
There is another separate Solar For All program, also funded by the state’s Green Bank. Primarily targeting low and middle-income households, the program is a partnership between the state and solar provider Posigen. The provider leases solar energy systems to these disadvantaged households at a special low rate supported by the state, allowing more Connecticut residents to use affordable solar power.
In addition to these state programs, homeowners in Connecticut are also eligible for the federal Solar Investment Tax Credit (ITC). This program grants a direct federal tax rebate equal to 26% of the cost of your solar installation. There is a time limit, however: this credit is set to decrease to 22% for solar energy systems installed in 2023, before disappearing altogether in 2024.
Going solar is an excellent way to avoid paying the high electricity rates in Connecticut, and there has never been a better time to do so. Both state and federal solar incentives are available for state residents, and it’s definitely a good idea to look into a residential solar installation before these generous programs expire. We highly recommend using our list of Connecticut solar companies above as a starting point for your search, but you should always ask around and compare a few quotes from different companies before committing to installing a system.
Yes, solar power is a great addition to your home or business in Connecticut. Not only are residential solar installations exempt from property tax in the state, going solar allows you to avoid paying the higher electricity rates in Connecticut. Check out our list above for some great solar companies operating in Connecticut!
Net metering in Connecticut is set to change in January of 2022 following a newly approved state plan, but it will not be going away. The current net metering scheme will still be available, albeit with electricity credits for excess power generation being rolled over indefinitely instead of reimbursed to you at the end of the year. In addition, a new buy-all/sell-all option will be accessible, where you sell all electricity generated by your solar power installation back to the grid at a fixed rate, and purchase all electricity you use at fluctuating retail rates. Read our net metering section above for more details!
Connecticut residents have access to the Green Bank Residential Solar Investment Program (RSIP), which provides a direct rebate of between $0.358 and $0.207 for each watt of solar power you install, up to 20kW per individual. The program is set to expire when 382 MW of capacity has been reached, however.
The federal Solar Investment Tax Credit (ITC) is also available, which provides a federal tax incentive worth 26% of what you paid to install solar.
No, in fact solar panels are often able to boost your home resale value! Real estate listing company Zillow estimates that installing residential solar can increase your property value by up to 4.1%. These findings are backed up by a US Department of Energy study, which also found that residential solar energy systems add an average of $4 per watt to your house prices. This works out to around a $15,000 boost in home value for a typically-sized solar installation.
