What are the pros and cons of installing solar panels in Connecticut?
The advantages of installing solar panels in Connecticut are that there is both state-based incentives and the federal tax credit available. In addition, Connecticut also has expensive utility rates which makes the overall return on investment for an installation of residential solar panels in the state one of the best in the nation.
The disadvantage of installing solar panels for your home in Connecticut is that there is less overall solar irradiation per year. So, a solar system produces less in Connecticut than it would in sunnier states, like Arizona.
However, the local and federal incentives more than make up for the limited sunshine in the state.

How much electricity will solar panels produce in Connecticut

per year per 1kW of peak DC
(direct current) capacity

What rebates, solar tax credits and other solar incentives are available in Connecticut
Renewable Portfolio Standard
Connecticut’s Renewable Portfolio Standard (RPS) requires the state’s electric providers to obtain a certain percentage of their energy from renewable sources. The RPS defines three classes of renewables: Class I, Class II, and Class III.
Solar is considered a Class I renewable. Connecticut set the target of having 48% of the state’s total energy to be derived from renewables in 2030, with 40% of that coming from Class I sources. Utility companies Eversource and United Illuminating have different policies regarding retaining RECs.
Net metering in Connecticut
There has been some controversy surrounding net metering in Connecticut. In 2018, the state legislature passed a bill that would end net metering and replace it with a low-value feed-in-tariff at the end of 2019. Luckily, in May 2019, a bill was passed that extended net metering until December 31, 2021. 2021 is still right around the corner, so the time to install solar is now, before net metering runs out!
The net metering policy requires utilities to provide their customers a credit for the full retail rate of any excess energy they export to the grid. For example, if you have a residential solar system and you generate more energy than you use for a certain month, you will receive a credit for the excess energy you produced that can be applied to your next month’s bill.
Residential Solar Investment Program
The Residential Solar Investment Program is administered by Connecticut Green Bank. The program offers two different incentives:
The EPBB incentive is an upfront cost reduction that is paid directly to the contractor on your behalf upon completion of your solar panel - meaning less money out of your pocket. The current rebate is equal to $0.463 per Watt.
The PBI, on the other hand, allows homeowners to enjoy the benefits of a solar system without the big upfront costs. Through this incentive, the homeowner enters into a contract with a third-party system owner. The PBI is then paid to the system owner based on the performance of the system over the course of 6 years. So, the third-party owner will receive $0.035 per kilowatt-hour (kWh) of energy produced by the system. This is used to reduce the homeowner’s monthly costs.
Tax exemptions
Connecticut offers two types of tax exemptions for solar systems: a property tax exemption and a sales tax exemption.
Historically, installing a solar system on one’s property would cause an increase in the value of property taxes, however, the property tax exemption exempts 100% of the assessed costs associated with the solar system from the homeowner's property taxes.
Not to mention, through the state’s sales and use tax exemption, solar system equipment is cleared of state sales tax - leading to even more savings.
