For a smaller state, the amount of solar energy production in Connecticut is pretty impressive, growing exponentially over the past decade.

Solar installation increased by 124 percent in 2015 alone. Likewise, by 2020, Connecticut is expected to install six times more solar—that’s 1,031 megawatts of additional solar electric capacity. Although Connecticut ranks 17th overall in terms of solar power, the Constitution State is expected to expand its solar efforts in the near future, hopefully moving the state from the middle of the pack to the front.

Connecticut Solar Panel Pricing

Monthly electric bills in Connecticut currently average $127, equaling about 17 cents per kilowatt of energy. When you take into account that the average solar panel installation costs between $25,000 and $35,000, it’s actually more affordable for most homeowners to go solar than depend on the utility grid for their electricity. Not only that, but photovoltaic cells are now 66 percent less expensive than they were in 2010, making it even more affordable for homeowners to install a home solar power system.

How the People of Connecticut Can Save With Solar Incentives and Rebates

Those interested in home solar have 79 money-saving incentives and policies at their fingertips. While you’re doing research, keep these options in mind to save even more on your electric bills:

Federal Tax Credit

Since August 2016, every homeowner in the U.S. (including Connecticut, of course) who buys solar panels can get 30 percent back in tax credits. Remember, this federal tax benefit only extends to people who own their solar panels, which means that leases, financing, and solar PPAs are not eligible. For home solar power system owners, it’s a valuable incentive that can help you save thousands of dollars.

Local Utility Incentives

Many utility companies offer solar-power incentives. Browse Connecticut tax and utility-provider incentives according to your zip code to see how you can save more on home solar.

Excess Energy Rebates

Utility companies in Connecticut are required by law to allow net metering. Essentially, at times, your solar panels will produce more energy than you use. When this happens, your utility company has to pay you for your excess energy. Homeowners are eligible for this incentive if they own their solar panel system.

Solar Legislation in Connecticut

The State of Connecticut is committed to producing more renewable energy. In fact, Connecticut plans to generate 27 percent of its electricity from wind, solar, geothermal, and fuel cells by 2020. In order to achieve this goal, state authorities have focused on making home solar more accessible to interested homeowners.

One specific way that Connecticut fosters solar development is through the Connecticut Clean Energy Fund (CCEF), which is part of a larger strategy to develop renewable-energy resources by linking public funds and private capital. The CCEF provides funding for four renewable-energy sources: geothermal, solar thermal, solar photovoltaic, and fuel cell programs.
