      We’ve talked to more than 2,000 Sunrun customers. Over a recent two-year period, 77% were satisfied with their installations, and 73% were satisfied with the technology. Many tell us about significant savings on electric bills. We also like that its leasing program lets you go solar without a significant upfront investment.

      • “We love Sunrun. I pay my sister's bills for her and her bill is really low. Everybody was very nice, very kind, and polite, and Zach's a sweetheart, too. He's a great salesperson. I love dealing with him.” — Shirley in Hartford
      • “The lady who sold the service to me was the only contact I had when nobody was answering me. She was above and beyond every time. She always helped me. I was thinking about getting the system for years and years and I was always busy but she convinced me and I got this because of her. The installers were respectful and did a good job. Sunrun’s service just started to work and it’s only been a month and a half that I’ve been out of the bill. But it looks promising.” — Charles in Hartford
      • “The installers were in and out in a day. The permitting process was well-organized and it was a very smooth experience. Sunrun is saving me tons of money. The app could be an area of improvement though. I'm an engineer and a data guy so I wouldn't mind drilling into more details.” — Joshua in Windsor

      “The reps were very helpful,” Carolyn in Hartford told us. “But there were a lot of bumps before we even got the system installed. It took a long time for them to get the panels up and for TEP to come. We had a hole in our front yard for three months. It was for the wiring for the solar. They had to have TEP come and check it. Also, their customer service isn't that great when you call. But my electric bill is now a lot cheaper and it's good that I can pay online.”

      We also suggest reading the fine print carefully. Some customers have said they are not satisfied with the contract and terms.

      Sunrun specializes in residential solar systems with battery storage. Installers use monocrystalline solar photovoltaic (PV) panels from reputable manufacturers like LG.

      • Energy services: Sunrun designs and installs customized solar panel systems for homes and businesses. Technicians provide ongoing maintenance and monitoring to ensure optimal performance.
      • Warranty information: Sunrun provides a 10-year warranty on workmanship and equipment, roof leak protection and a 25-year performance guarantee.
      • Payment options: You can pay for your system upfront or take out a loan, but Sunrun leasing plans really set it apart. With leases, there’s no initial charge for panels, equipment, installation or permits. Sunrun owns the system, and you pay a fixed monthly fee to use it. Contracts typically last 25 years and include free repairs.

      Pros

      • Reliable systems
      • Flexible payment options
      • Comprehensive warranties
      • Daily system monitoring

      Cons

      We’ve talked to more than 50 Project Solar customers from across the country. Over a recent two-year period, 94% were satisfied with the price. Satisfaction ratings on customer service and technology were also above industry averages.

      Project Solar reps focus on simple, streamlined installations. The no-sales-gimmicks approach appeals to more budget-conscious clients who want either professional services or do-it-yourself options. We also appreciate the price transparency. Full-service installations start at $1.61 per watt. DIY projects are cheaper, starting at $1.26 per watt.

      The installation process is generally smooth and professional, but we have heard about some delays due to material shortages or supply chain issues.

      Project Solar specializes in professional and DIY solar PV panel installations. Systems incorporate equipment from reputable brands like Qcells, Canadian Solar, Silfab and Enphase.

      • Energy services: Reps can handle the necessary paperwork, engineering plans and permit submissions for the installation. You can get a free online quote and explore sizing options for their homes.
      • Warranty information: There is a 25-year manufacturer’s warranty and a 10-year workmanship warranty. Both are limited and have exclusions like weather damage or misuse.
      • Payment options: Project Solar partners with a few lenders to offer financing solutions for professional solar installations. DIY customers can pay cash or finance through a third-party lender.

      Pros

      • Easy sign-up process
      • High-quality equipment
      • Great value

      Cons

      • Occasional miscommunications
      • Subcontracted installers
      • No in-house financing

      Hartford solar panel buyers guide

      We’ve talked to dozens of Connecticutians who have already gone through the solar panel installation process. Here’s what Hartford residents should look out for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with government incentives.

      Key insights

      A typical residential solar panel installation costs $28,644 in Hartford.

      Jump to insight

      Solar loans, leases and other programs make it easy to go solar with minimal upfront costs.

      Solar panel costs in Hartford

      A typical solar panel installation costs anywhere from $10,360 to $29,600 in Connecticut. Prices in Hartford are comparable, ranging from $10,780 to $30,800.

      This doesn’t include an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing, like at night or during outages. It’s worth considering if your area gets frequent blackouts or if you don’t opt into Hartford’s renewable energy certificates (RECs).

      On the high end, Priya in Colchester told us they invested $50,000 going solar. System size is the other major solar cost factor. The average Hartford household needs a system with a capacity of 9.3 kW (kilowatt) to fully offset their electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.

      How can I pay for solar panels?

      Getting solar panels is like buying a car. Most people pay cash, finance or lease. Similar to leasing, a power purchase agreement (PPA) lets you get the benefits of solar without actually owning the equipment.

      • Solar loans work like any other type of loan. They have relatively low fixed interest rates. Once you pay it off, you own your system outright. You might be eligible for Connecticut Green Bank’s Smart-E Loan program.
      • Solar leases are a good option if you have limited savings and don’t want to take on debt. A potential downside to leasing is that you won’t be eligible for the federal solar tax credit.

      Is solar worth it in Hartford?

      Solar panels are generally worth it in Connecticut if you like the idea of lowering your monthly utility bills. On average, Hartford homeowners with solar panels can avoid $63,114 in total utility costs over 25 years.

      The main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 6 years to break even (when your savings with solar panels make up for the cost).

      Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.

      Micah in Mansfield went solar in 2021. “I'm also happy with how they're working and the amount of electricity they're bringing in. The most recent bill was down to $10.”

      Another local, Neal in East Haven, told us that going solar “was one of the best decisions of our life. We were paying at $400 month for electric and our system only cost us $300 month (already saving $100 month) for several years, then literally $0 per month thereafter.”

      Considering Connecticut averages 2.5 to 3.5 peak sun hours each day, switching to solar is also worth considering for the environmental benefits. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator. 

      Potential roof problems

      As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This is an expensive and frustrating process. For instance, Richard in New Milford said he was quoted more than $10,000 to remove and replace 39 panels.

      How to find a reputable solar company in Hartford

      In our experience, the best solar companies in Connecticut have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.

      • Check certifications: We recommend choosing an installer certified through the North American Board of Certified Energy Practitioners (NABCEP).
      • Read reviews: Avoid companies with recurring complaints about misleading sales tactics, equipment failures, billing issues and lack of communication.
      • Compare costs: Get multiple solar quotes from different companies to make sure you’re getting the best deal.
      • Ask questions: Do you need a solar storage battery, electric vehicle (EV) charger or critter guards? How does this affect overall pricing? What if your system needs maintenance? If you don’t understand something about the payment terms, warranty or ongoing services, ask for clarification.

      While not as snowy as some northern states, Hartford does get snow. Ensure your installer considers snow load when designing your system and uses appropriate mounting methods.

      Residential solar panel incentives in Hartford

      The 30% federal solar investment tax credit (ITC) is the best incentive for most Hartford homeowners. It reduces your federal tax liability by 30% of how much it costs to install solar panels. You can combine the ITC with local solar incentives in Connecticut to maximize savings.

      For instance, you don't have to pay sales tax on solar equipment. There's also a property tax exemption on solar equipment. A solar property tax exemption means that your property tax bill won't go up because your solar panels increase your home’s market value.

      Hartford solar FAQ

      How does the federal solar tax credit work?

      The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which lowers your taxable income.

      For example, if you spend $10,000 installing a solar panel system, the ITC is worth $3,000. If you owe $5,000 in taxes, the $3,000 credit reduces what you owe to $2,000. Any unused portion rolls over to the next tax year. However, getting a refund check is possible if the ITC credit reduces your taxes to the point where you overpaid during the year.

      Can my HOA stop me from installing solar panels?

      No, the Connecticut Clean Air Act specifically says that your homeowners association (HOA) cannot ban solar panels.

      How does net metering work in Hartford?

      Sometimes, your solar panels might generate more electricity than your household needs. Net metering lets you send that excess power into your local power grid. In return, you can earn credits on future utility bills. As of January 2022, the company switched to renewable energy certificates (RECs), which also work by offsetting your bill when your solar panels don't produce as much energy, like on especially cloudy days or during Hartford’s long, dark winters. Hartford is primarily served by Eversource.

      What are the different types of solar panels?

      Monocrystalline and polycrystalline are the most common types of solar panels used in residential installations. In general, monocrystalline panels are considered the best bang for your buck. Cheaper solar panels are typically polycrystalline. The key difference is in materials and efficiency: Monocrystalline panels use pure, single silicon crystals, while polycrystalline panels are made from melted silicon fragments, resulting in different efficiency levels.

      Solar panel efficiency is a measure of how well a panel makes electricity. Standard efficiency rates range from 19% to 23%, which means 19% to 23% of the sunlight that hits the panels gets converted into electricity. The more efficient the solar panels you buy are, the fewer panels you need. While more efficient panels cost a little more, you save by buying fewer panels.

      Can I get solar panels for free in Hartford?

      We’re not aware of a totally free solar option in Hartford. You can lease or enter a power purchase agreement with minimal upfront costs, but there is usually an ongoing monthly fee. In general, beware of deals that sound too good to be true. 

      How does a power purchase agreement work?

      A third party installs and maintains solar panels on your property. You buy the power generated by the panels on a per kilowatt-hour (kWh) basis. It’s typically a fixed price, with a cheaper cents/kWh rate than traditional utilities have for the same amount of electricity.
