Solar tax credits and rebates help to reduce installation costs as well as save you money long-term. Get details about Connecticut’s top solar incentive programs below.

Connecticut Green Bank Solar for All Program

The Connecticut Green Bank is a state-sponsored organization that promotes energy efficiency and clean energy use through various financial incentives. The organization’s current incentive, the Solar for All Program, helps eligible low-income households access solar energy through a power purchase agreement (PPA) or solar lease at reduced rates.

Contract terms for this program vary from customer to customer. The contracts have no up-front costs and guarantee customer savings without hidden fees or escalating lease payments.

Residential Property Tax Exemption

Solar panels increase a home’s value by roughly $15,000, which usually means property taxes rise. However, the Connecticut Department of Revenue Services has a residential property tax exemption for renewable energy systems. This means you won’t have to pay increased taxes after installing your solar energy system.

Sales and Use Tax Exemption for Solar and Geothermal Systems

The Connecticut Department of Revenue Services allows residential property owners who choose to install solar panels or geothermal heating and cooling systems to benefit from a complete exemption from state sales and use taxes. This exemption means you avoid an additional 6.35% home solar system state sales tax on the total cost of your solar panel system.

How Does the Federal Solar Tax Credit Work?

All Connecticut homeowners can use the federal solar investment tax credit (ITC). You apply for this credit during tax time to reduce or eliminate your owed federal taxes. The current rate allows you to claim 30% of your solar installation costs. The remaining amount can roll over to the next tax period if needed. You must own your system to receive this incentive, so those with solar leases and power purchase agreements don’t qualify.


Is Net Metering Available in Connecticut?

Net metering allows solar customers to send excess energy from their systems to the electric grid in exchange for credits on their electricity bills. Homeowners can use these credits to offset energy costs at night or during cloudy, low-sunlight days.

Connecticut’s net metering policy is subject to specific regulations and limits. The amount of excess energy that can be credited might vary based on the utility company. Eversource offers one of the state’s largest and most well-developed net-metering programs.


How Much Do Solar Panels Cost in Connecticut?

Solar panels have an average national cost of $20,650. According to data from EnergySage, the average cost of solar panel installation in Connecticut is $19,380 for a 6-kilowatt (kW) system. Applying the federal solar tax credit saves $5,814 for a total of $13,566.

Your solar financing option determines your system’s overall cost and possible payback period. Here is a brief overview of each option to help determine which is right for you. 

  • Cash purchase: This option involves paying your full solar energy system cost up-front. Though this means a significant initial investment, you’ll receive the highest long-term savings. Cash purchasers also benefit from all available tax incentives and rebates. 
  • Solar loan: Solar loans allow homeowners to finance the cost of their solar energy system over a fixed term, often with a low interest rate. A solar loan makes you eligible for all incentives since you own the system.
  • Solar lease: A solar lease involves paying a fixed monthly fee to use solar panels. This option is less expensive in the short term, but the solar equipment remains the property of your installer, which means you won’t be eligible for solar incentives that would otherwise save you money. You also won’t receive other benefits, such as raised property value.
  • Power purchase agreement: PPAs are similar to solar leases, but instead of paying to use the equipment, you pay for the energy you use. Customers agree to buy the electricity the solar system produces at a predetermined rate, which is often lower than their utility company’s retail rate. Unfortunately, this option makes you ineligible for solar incentives.

Is Going Solar in Connecticut Worth It?

Connecticut offers plenty of incentives that make solar power worth it. The state provides a robust net metering program, enabling you to earn credits for excess electricity your solar system generates and feeds into the grid. These energy credits can substantially reduce utility bills, leading to long-term savings. Additionally, the state’s residential property tax exemption and Solar for All Program significantly offset up-front solar panel installation costs.


Our Conclusion

Connecticut residents have several ways to save money on solar. Our guide covers the key solar rebates and incentives available in the state, but smaller city- or municipality-specific incentives are also worth exploring. We suggest checking DSIRE for more information.
