Solar Panels in Connecticut: Cost, Savings, and Rebates

Over 10,000 residential solar arrays were installed in Connecticut in 2021. This suggests growing support for renewable energy in the Nutmeg State. And while the weather in New England might seem less than ideal, there’s a reason homeowners are making the switch.

The cost of solar panels in Connecticut offset a high electrical cost that can save people thousands of dollars. Want to know where to start? Continue reading for average prices, cost factors, and how much you can expect to save.

Average Cost of Solar Panels in Connecticut

At first glance, homeowners might hesitate after discovering the cost of solar panels in Connecticut. Averaging about $2.86/W, Connecticuters could expect to spend $17,160. This stands as one of the highest rates in the United States, costing over $2,000 more than western states such as Colorado.

However, this is where the bad news ends; in reality, Connecticuters have some of the best opportunities to offset some of the highest traditional electricity rates in the country. With an average monthly utility bill of $159.41, homeowners in the Nutmeg State pay more than any other state for power, except for Hawaii. This means that a switch to solar could result in massive net savings over the course of a system’s lifetime.

And that’s only where the benefits start; homeowners making solar purchases in 2023 can take advantage of a federal solar tax incentive worth 30% of the overall payment. This would drop that 6kW array worth $17,160 down to $12,012.

How Much Solar Do Connecticuters Need?

Now, the above examples only provide an estimate for the typical cost of solar panels in Connecticut. However, you can find a more accurate ballpark price in just a few steps. Dividing your average electricity usage by the peak sun hours where you live, you can determine how much wattage your household needs. We’ll use Conneticut’s averages in the case study below.

According to SolarReviews, installing solar panels in Connecticut provides an estimated 15.6% return on investment.


According to records, homeowners in the Nutmeg State use about 23.7kWh daily (or 711kWh/mo). Dividing that by 3.84 peak sun hours (the state average), a solar array should produce 6.2kW an hour. This means that the average Connecticuter would spend about $17,732 before discounts apply.

Now that you know how to determine the amount of wattage you need, try it for your own household. You can discover the peak sun hours for your nearest city using this sun chart.

Connecticut Solar Cost Factors

As mentioned above, peak sun hours are one of the biggest aspects that affect the cost of solar panels in Connecticut. This is especially true with the Nutmeg State, which has some of the cloudiest weather in the country. In some parts of Connecticut, it’s possible to receive less than 3 hours of peak sun a day. We can see how geographic location affects price by comparing the surrounding states:

Connecticut’s sun exposure has such a critical influence on solar that homeowners should seriously consider types of solar panels. While polycrystalline panels come more affordably, their poor efficiency makes them less than ideal in cloudy areas like New England.

In this case, Connecticuters should purchase monocrystalline panels; they’re a little more expensive, but their efficiency will help keep your household powered even in inclement weather.

Finally, choosing the right installation company can affect the price of your solar panels; not only in the short term but over the course of your system’s lifetime. Because of its size, there aren’t many local installers in Connecticut to choose from. However, the options available have made a quality reputation for themselves.
