Our list of best solar companies that operate in Connecticut may be some of the largest providers in the state, but there are plenty of smaller local solar companies in Connecticut that may provide more personalized services. Here are a few to keep in mind:

• Premier Improvements Solar: Available in six cities in Connecticut, Premier Improvements Solar is a veteran-owned solar company that has installed over 1,000 solar panel systems throughout the state. It offers 25-year equipment and workmanship warranties.
• Ion Solar Pros (iSP): Located in Middlebury, Connecticut, iSP installs solar panels, EV charging stations and battery storage to homes in Connecticut, Massachusetts and New York.
• Earthlight Solar and Energy Solutions: Earthlight Solar operates in Connecticut, Massachusetts and Oregon to provide solar energy, solar storage and EV charging stations to residential homes.

Finding the right solar company in Connecticut for your home installation is key to having the system you want, quality services and long-standing warranties that protect your investment. According to the Solar Energy Industries Association (SEIA), Connecticut has 55 installers and developers competing for solar services. To help you settle on a reputable company, follow these steps:

1. Decide on which solar equipment you want to install. Not all companies carry solar batteries or a variety of solar panels, so this can quickly help you narrow down the results.
2. Once you’ve found installers that carry the items you want, gather at least three companies to compare prices, services, equipment and reviews.
3. Research the quality of the solar panels and equipment to ensure you’re investing in the best solar panel system that will hold up and perform well during its lifetime.
4. Look at each company’s reputation on unbiased third-party websites like Forbes, Google Reviews, Yelp and the BBB.
5. Check the warranties for the products, performance and workmanship. Top Connecticut solar installers have 25-year warranties or greater for the panels and labor.
6. See which payment options are available. If you don’t plan on paying in cash, do you want a solar lease or power purchase agreement (PPA), solar loan or some combination?

The average cost of a solar panel system in Connecticut ranges from $16,600 to $20,500. This is for the average solar panel system of 6.5 kilowatts (kW), but you could spend less or more depending on the size of your system.

Solar Panel Cost Factors

Solar panel costs can vary from $7,700 up to $34,700, so consider these factors to help you know exactly what determines the cost of your solar panels.

• Size: A 3-kW solar system is going to cost significantly less than an 11,000-kW system. Generally, solar panels cost between $2.55 and $3.15 per watt, so your household size and energy consumption play a huge role in determining the size and cost of the system.
• Quality: Higher-quality solar panels utilizing the latest technology will cost more than older solar panel designs that are less efficient. You can expect to spend more on Tier 1 panels that have N-type solar cells than you would on Tier 3 panels that use P-type cells.
• Labor: Every installer has their own way of calculating costs and writing up a quote, so be sure to shop around and compare rates to land the best deal. Ask for an itemized breakdown of the services you’re going to receive to compare.
• Brand: Name-brand companies with outstanding reputations may have higher price tags to show for it, but the quality may outweigh the cost in the long run by providing you with more energy for the same system size as lower-performing brands.
• Additional equipment: If you need to install solar batteries, then you can expect an increase of $1,700 to $9,000 to have that energy backup system installed.

Connecticut doesn’t have very many solar incentives in place, but there are several that can help you pay for or save money on your solar panel system, including:

• Federal Tax Credit: As part of the Investment Tax Credit (ITC), the federal solar tax credit is a 30% credit on your annual tax return. It’s set to expire at the end of 2025.
• Residential Renewable Energy Solutions (RRES) Program: This program replaced the net metering program that was in place in Connecticut. It’s a 6-year-long program that gives tariffs to residential customers who send electricity to the local electric grid.
• Sales Tax Exemption: Connecticut offers a 100% sales tax on the purchase of solar systems. The sales tax in Connecticut is 6.35%, so you save around $1,180 on taxes for an average $18,600 solar panel system.
• Property Tax Exemption: Solar panel installations are eligible for a 100% property tax exemption.
