Watch Below: Why Are Solar Batteries Important and Will CT Pay You To Install One?

How to Save Money When Hiring a Solar Company in Connecticut

The average size of a residential solar panel system in Connecticut is 7.5 kW, which should offset the average monthly consumption of 711 kWh. Given that most solar panel systems in Connecticut cost $3.49 per watt, an average-size solar system would cost $26,175 before the federal tax credit and $18,323 after.

The initial cost to go solar in Connecticut is slightly below than the national average — $29,970 before the credit and $20,979 after. Plus, Connecticut also has one of the highest energy costs in the country, meaning you have more potential to save when you go solar. All in all, Connecticut residents stand to save more with solar than residents in most other states. The average savings in CT sit at $58,012, which is nearly double the national average of $31,513.

In Connecticut, you can save money when you go solar by:

  • Taking advantage of local and federal incentives and rebates
  • Comparing quotes from different solar companies
  • Paying in cash or putting more money down when possible

Take Advantage of Local and Federal Incentives and Rebates

A solar contractor can help you apply for solar incentives available in your area. Connecticut residents are eligible for the following solar incentives:

Connecticut Solar Incentive Description
Federal Solar Tax Credit (ITC) The federal solar tax credit is worth 30% of your entire solar panel system cost and is available to all homeowners who purchase and install their systems by December 31, 2032. The credit will decrease to 26% in 2033 and 22% in 2034.
Sales and Use Tax Exemption for Solar and Geothermal Systems Connecticut homeowners don’t have to pay sales tax on their solar equipment or installation services.1 Given the state tax rate of 6.35% and the average system total of $26,175, this equates to an average savings of $1,662.
Property Tax Exemption for Renewable Energy Systems Normally, any time your home’s value increases, your property taxes will go up as well. Although solar panels boost your home value in Connecticut — if you purchase or finance them — the property tax exemption guarantees that your taxes won’t spike as a result.2
Solar Loan Programs The average cost to go solar in Connecticut is most easily afforded with solar financing, and the state makes solar loans affordable and accessible to most homeowners. There are several solar loan programs available in Connecticut that you can use to finance your panels for little or no money down and with a low interest rate.

We’ll discuss these options in greater depth below.

Net Energy Metering Net metering is a billing policy that utility companies offer to help customers offset electric bills using interconnection. Basically, you can overproduce power with your panels, and your account will get credited based on the energy you send to the electric grid.3

The State of Connecticut mandates net metering. We’ll discuss the specifics of the policy below.

Compare Quotes From Different Solar Companies

Like any other home improvement project, it’s wise to compare quotes between solar installers before you decide which one to hire.

The cheapest quote isn’t necessarily the best deal. Do your research about solar panel brands, and find a reputable solar company in your area.

Pay in Cash or Put More Money Down When Possible

Paying for your solar panel system in cash upfront is the best way to avoid paying more for your solar panels through interest fees.

We understand that paying for solar panels in cash is not realistic for most people. In this case, paying a little more on your down payment or your monthly bill can help you pay for your panels faster and pay less in interest.

Cash payments will become even less viable in the future when batteries are mandatory for maximizing savings, but for now, they should remain a possibility for some homeowners.

Will Solar Increase Your Home Value in Connecticut?

Yes, installing solar panels on your home will increase its value. Zillow estimates that a home with solar is worth, on average, 4.1% more than a home without solar. The average home value in Connecticut is $381,629, so that’s an extra $15,646 in value added.4

In Connecticut, you don’t have to worry about paying additional property taxes either. Connecticut offers a 100% property tax exemption on the added value of your home when you install solar panels.

Should Connecticut Residents Hire a Professional Solar Installer or DIY?

If you have a DIY spirit, you may consider installing solar panels yourself. So, is it a good idea?

Well, it depends. Installing solar panels yourself can save you from paying labor costs, but you’ll also have to source installation equipment, secure the necessary permits to complete the project and take the time to install the panels.

Considering labor costs for solar panels typically make up around 10% or more of your final project, around $2,600 in Connecticut, you have to weigh your options.

Installing a solar system yourself has a few significant downsides. We only recommend considering a DIY solar installation if:

solar panel installation on commercial building

  • You have advanced electrical contracting or solar installation experience
  • You have acquired all permits and approvals
  • You have the necessary supplies (including, but not limited to, a digital multimeter, battery-operated drill, hack saw, pry bar, caulk gun, conduit blender, screwdrivers, wire stripper, wire cutter and solar panel hanger)

If at least one of these do not apply to you, we strongly recommend hiring a professional.

What Should Connecticut Residents Look For in a Solar Installer?

When looking for a solar installer, make sure that the solar installation company you hire operates locally, has great customer service and offers the brands and services you want. Here’s why:

Operates Locally

A solar installer local to Connecticut will understand the weather, permitting requirements and local incentives and rebates more than someone from out of state. You’ll also be able to have a contractor come out more quickly in case something goes wrong.

Great Customer Service

Communication is at the heart of customer service. You want a solar company that will communicate with you every step of the way. If there’s a delay, you should know about it. If you need a question answered, you should have a quick response.

Great customer service is at the heart of a positive solar installation experience. If a company is honest, knowledgeable and responsive, your installation will be much smoother.

In order to know whether or not a company offers great customer service, do your research. Read online reviews on trusted websites like the Better Business Bureau (BBB).

Offers the Services, Brands & Financing You Want

Maybe you’re not sure what type of solar panel system you want yet. Or maybe you have every little thing planned out.

Either way, you want to work with a solar company that offers top-quality brands and has a variety of financing options that fit your needs.

For instance, not all installers offer solar energy systems with battery storage, which is going to be a bigger deal once net metering 3.0 takes effect, as it already has in California. Other installers don’t offer solar shingles, only panels. Long story short, if a company doesn’t offer the services you need, you’ll just be wasting your time.

Most people can’t afford to pay tens of thousands of dollars for a solar system upfront, so make sure your installer offers a variety of financing options that you feel comfortable with. There are plenty of options out there, so don’t be shy in shopping around for the right fit.

If you’re ready to get connected with a solar provider that offers all of the brands, financing and services that you prefer, select one of our top providers below to get started with a professional.

Methodology: How We Reviewed the Best Solar Companies in Connecticut

There are over 60 solar installers in Connecticut, so we had our work cut out for us finding the best of the best. We ranked companies based on six main criteria that we believe are the most important for having a positive experience as a customer and getting a reliable system for your home. We’ll explain these six main factors below and explain why we think they’re so important.

  • Local reputation and reviews (20%): With so much demand for solar and so much competition in Connecticut, we first sought to weed out companies that are less reputable and are more likely in the local solar industry just to turn a profit. We read through dozens of reviews for each provider to determine where they fell short of customer expectations.
  • Pricing and financing (20%): Connecticut is one of the more expensive states in the country for solar equipment, with a per-watt price of $3.49, compared to the national average of $3.33. Since equipment prices are so high, we prioritized companies that maintain average or below-average pricing, as well as those that keep products and services widely accessible by accepting a myriad of payment options.
  • Services offered (20%): Many Connecticut solar customers look for add-on products to customize their systems and maximize their returns on investment. Batteries are more popular than ever before because of the downgraded net metering program in CT, EV popularity is booming and making EV chargers a popular option and well-above-average electricity prices mean many customers seek out energy audits and other efficiency improvements. We give priority to installers that offer a wide array of products and services, as they will naturally appeal to more residents.
  • Warranty coverage (20%): Connecticut sees about 1.5x the national average amount of rainfall each year, and it sees extreme weather regularly as a coastal state. This puts rooftop panels at an increased risk of damage, which means lengthier labor and equipment warranties are welcome. We rank companies higher than provide above-average coverage to keep systems protected.
  • Company experience (10%): In areas with a high demand for solar, like Connecticut, a lot of fly-by-night companies pop up to take advantage. Unfortunately, these companies often don’t understand the local energy needs of customers, nor do they provide the same kind of customer service that more established companies do. We prioritize companies that have ten or more years of experience, especially because they’re less likely to go out of business and void your warranties in doing so.
  • Brand quality (10%): Finally, we consider the panel brands offered by each installer. Connecticut has a unique mix of customers looking to avoid above-average installation prices and those looking to install peak-efficiency panels to avoid some of the country’s highest electricity prices. We prefer companies that install a range of panel brands that appeal to both groups.
