Although Connecticut isn’t known as the land of solar, it is quickly becoming an excellent state to purchase and install solar panels. New tech development and various financial incentives have made it easier to produce solar electricity in less sunny climates. A solar power system in your home can ensure minimal initial system costs and steady savings for decades to come.

For these reasons and more, it is a great time to buy a new solar energy system in Connecticut. Keep reading to learn how your purchase and installation of solar panels in Connecticut can become cheaper and more efficient.

Why Go Solar in Connecticut?

Although it may not have a wealth of sunshine, Connecticut is a great place to invest in solar. With an average of 194 sunny days per year, Connecticut is not much below the American average of 205 sunny days per year. Despite its somewhat average sun coverage, Connecticut has benefited from rapid improvements in photovoltaic technology, which has increased the efficiency of solar panels so that even cloudier and colder climates can sustain solar energy production.

Connecticut is also an excellent state to purchase solar energy systems because of the existence of federal, state-level, and local financial and tax incentives designed to lessen the cost of buying and installing solar panels.

In particular, the government of Connecticut has a Renewable Portfolio Standard, which requires energy producers to produce a certain amount of electricity from renewable sources. Residents of Connecticut can benefit from the existence of many local solar providers throughout the state. These providers offer customers the opportunity to entertain competing quotes while ensuring they receive the best quality service and equipment.

Finally, solar panels can dramatically increase your home’s value. According to Zillow, the average home experiences a 4.1% increase in value after adding a solar power system. In Connecticut, the average home value is $340,415, meaning homeowners can expect to see their home values increase by an average of $13,957 after installing a photovoltaic energy system.

Connecticut Solar Cost

The total cost of solar installations in Connecticut ranges from $13,090 to $17,710. On a cost-per-watt basis, solar panel installation in Connecticut falls between $2.62 and $3.54. Given the national average of $3.00 per watt, Connecticut is far from the pricier end when buying solar energy systems.

You should also note that these costs have decreased significantly in recent years. In fact, over the past five years, prices have dropped more than 45% in Connecticut. If you purchase a larger system (more watts), you will spend more to gain additional energy production. With energy bills increasing amid high oil and gas prices, the relative cost of solar is surely bound to continue declining.

How Much Can You Save on Solar in Connecticut?

Although you may face steep upfront costs to purchase and install your solar system, you can save lots of money annually, thanks to your system’s electricity. The mechanism behind the savings functions in this manner: when solar panels produce electricity for your home, they reduce the amount of energy that you pull from the grid, thus lowering your utility bills.

People living in Connecticut save between $30,290 and $40,981 over 20 years. With a payback period ranging from 7.4 to 10 years, you can save thousands of dollars per year just close to a decade after purchasing your photovoltaic (PV) equipment.

House Method’s Solar Companies Rating Methodology

At House Method, transparency and trust are our most important values for the reader. That’s why we took the time to create an objective rating system and score each solar energy company/service according to our methodology.

Our research team dug deep into the fine print of contracts, combed through more than one hundred customer reviews, and thoroughly investigated all of each solar energy company’s services, costs, and products. We’ve done the homework for you by researching nearly all of the solar energy companies on the market so you can have the information you need to make the best choice for your home.

We developed a formula to objectively determine the best solar energy companies and give each a score out of 100 based on the following criteria:

  • Plan Options (30): Do they provide a variety of plan options? We looked at the number of plans each solar energy company offered and the flexibility of adjusting the plan.
  • Services offered (20): How many services are offered in each plan? We looked at whether the company manufactures its own solar panels, whether it contracts out installation, and what additional products each company offers.
  • Trust (10): What do customers say after their solar panels are installed? Does this company offer a guarantee? We considered how satisfied customers are post-service if the company does what it says it will, BBB accreditation, and service guarantees.
  • Prices (10): How reasonable are the costs of the plan or service in comparison to the industry average? We compared the costs of each company to competitors that offer the same solar energy services.
  • Unique perks (10): Does the company offer discounts or special services such as financial incentives, rebates, or a useful mobile app? We looked for extras each company offers that set them apart from the competition.
  • Customer Service (10): How is the customer experience when contacting the company? We considered the speed of response, weekend/holiday availability, and ease of communication through phone calls, email, and online chat functions.
  • Nationwide availability (10): How many states does the company offer its services? Companies that operate nationally and in all zip codes are favored over those with limited availability.
