Title: Everything You Need to Know About Solar Energy Tax Credits in Connecticut

Switching to solar energy is a savvy move for Connecticut homeowners and business owners alike, thanks to the significant financial incentives available at both federal and state levels. Understanding these incentives can greatly reduce the upfront costs of solar panel installations, making renewable energy more accessible and affordable.
This detailed guide will walk you through everything you need to know about solar energy tax credits in Connecticut, eligibility requirements, and how to maximise your savings with the trusted experts at A1 Solar Pros.
Understanding Solar Energy Tax Credits in Connecticut
What Are Solar Energy Tax Credits?
Solar energy tax credits are government-backed financial incentives designed to encourage the adoption of clean energy solutions, like solar panels. These tax credits reduce the amount of tax you owe based on a percentage of your solar system’s cost, leading to substantial reductions in installation expenses.
Primary Federal Incentive: The Residential Clean Energy Credit (formerly ITC)
The most substantial tax credit available to Connecticut residents and businesses is the Residential Clean Energy Credit (formerly known as the Investment Tax Credit or ITC). This federal program offers a 30% credit of the total cost of installing solar panels, including equipment, labor, and permitting fees, through the end of 2032.
For example, if you install a 6 kW solar system costing $18,000, you’ll receive a tax credit worth $5,400, reducing your net system cost to approximately $12,600.
Key points:
- The credit applies only to purchased systems (cash or solar loans) and NOT to leased systems or Power Purchase Agreements (PPAs).
- You claim the credit by filing IRS Form 5695 with your federal tax return.
- If your tax liability is less than the credit, the unused amount can be rolled over to future tax years.
Connecticut State-Level Incentives
Connecticut offers several complementary incentives to further reduce the cost of going solar:
1. Sales and Use Tax Exemption
Solar energy systems in Connecticut are exempt from the state’s 6.35% sales tax, meaning that the purchase of solar panels, inverters, and related equipment is not subject to sales tax. For a typical $18,000 system, this exemption saves about $1,143 immediately.
2. Property Tax Exemption
Installing solar panels increases your home’s market value but won’t increase your property taxes thanks to Connecticut’s property tax exemption on renewable energy systems. This means you can enjoy the benefits of a more valuable home without extra tax burdens.
3. Residential Renewable Energy Solutions (RRES) Program
Replacing the previous net metering system, the RRES program offers two ways to earn credits for excess electricity your solar system produces:
- Netting Tariff: Earn credits equal to the retail rate per kilowatt-hour for excess electricity sent back to the grid, offsetting future electricity bills.
- Buy-All Tariff: Sell all solar electricity to your utility at a fixed rate (~$0.3189 per kWh), receiving credits on your bill or quarterly payments.
This program helps homeowners maximize returns on their solar investments by effectively valuing excess energy generation.
4. Smart E-Loan Program
The Connecticut Green Bank offers low-interest loans specifically for solar and energy-efficient home improvements:
Loan terms range from 5 to 20 years with interest rates between 6.99% to 7.99%.
Allows up to 25% of the loan for non-energy-related repairs, useful if your roof needs work before solar installation.
Solar Energy Tax Credits for Commercial Properties
Businesses in Connecticut can also leverage attractive solar tax credits:
- The same 30% federal Residential Clean Energy Credit applies to commercial solar projects.
- Commercial properties benefit from sales and property tax exemptions similar to residential customers.
- Financial incentives through utility programs and the state may be available for energy storage systems paired with solar.
These credits substantially reduce upfront costs and improve the return on investment in commercial solar systems.
By investing in solar, businesses not only decrease their operational costs but also demonstrate commitment to sustainability—an increasingly important factor for customers and stakeholders.
Eligibility and How to Claim Your Tax Credits
To qualify for solar energy tax credits in Connecticut:
- Your solar system must be newly installed and located on a residential or commercial property in Connecticut.
- The system must be owned by you, either outright or via financing (loans), not leased.
- Installation must be fully completed, and proof of purchase and installation must be maintained.
- To claim the federal Residential Clean Energy Credit:
- Complete IRS Form 5695 and submit it with your federal tax return.
- Keep all receipts, contracts, and documents related to your solar purchase and installation in case of audits.
- Consult with a tax professional to ensure correct filing and to confirm eligibility for other state programs.

Additional Financial Benefits Beyond Tax Credits
While tax credits cover significant costs, solar energy offers other financial advantages:
- Energy bill savings: Connecticut’s high electricity rates mean solar power can reduce utility bills by 20-30% or more.
- Net metering credits: Earn credits or payments for excess solar power sent to the grid.
- Increased property value: Solar-equipped homes tend to sell faster and at higher prices.
- Long-term warranties and low maintenance costs: Providing peace of mind and predictable energy expenses.
These factors combine to make solar installation a wise, long-term financial investment.
When to Act: Federal Tax Credit Deadlines
The 30% federal solar tax credit is guaranteed through 2032 at current rates, after which the percentage begins to phase down. Solar projects installed before December 31, 2025 will still fully qualify, so homeowners and businesses interested in benefiting from the maximum incentives should start the process soon.
Conclusion
Solar energy tax credits in Connecticut make investing in solar panels more affordable than ever. By combining the powerful federal Residential Clean Energy Credit with Connecticut’s state sales tax and property tax exemptions and the Residential Renewable Energy Solutions program, you can significantly lower your solar investment costs.
