With the growing push toward sustainability and rising energy costs, commercial solar has become an attractive option for businesses across the Northeast. But when it comes to financial support, each state plays by different rules. In this post, we’ll discuss how Connecticut compares to its neighboring states—Massachusetts, New York, and New Jersey. When it comes to commercial solar energy incentives, we have a specialized focus on solar tax incentives for Connecticut businesses because that’s where we are headquartered. 

Connecticut: 

Key Programs & Incentives:

• Non-Residential Renewable Energy Solutions (NRES) Program:
  Connecticut’s traditional incentive program for commercial solar installations, NRES offers two structures:
  
  
  • Buy-All Tariff: Businesses sell 100% of their solar energy to the utility at a fixed rate.
    
    
  • Netting Tariff: Allows for onsite energy usage, with bill credits for excess production.

While both options outlined above offer valuable benefits, the Connecticut NRES program does present certain limitations. Notably, it operates through a lottery system, which can result in extended time periods for approval.  In some cases, the time from award to installation can span several years. However, Connecticut also offers alternative incentive programs with significantly shorter timelines. These options can facilitate project installation within as little as three months, while still delivering a strong return on investment.

• Tax Incentives for Commercial Solar in CT:
  Among the top Connecticut commercial solar tax incentives are:
  
  
  • Sales Tax Exemption: Solar equipment is exempt from Connecticut’s 6.35% sales tax. This exemption significantly reduces the upfront cost of installing a commercial solar system. It applies to a wide range of qualifying equipment, including panels, inverters, and mounting hardware. Businesses can reinvest these savings into other areas of energy efficiency or operations. Solar equipment is exempt from Connecticut’s 6.35% sales tax.
    
    
  • Property Tax Exemption: Solar systems are not included in property tax assessments, lowering long-term ownership costs. This exemption ensures that the added value of your solar installation doesn’t increase your property tax bill. It makes solar a more attractive investment by improving the financial return over time. As a result, businesses can realize both immediate and ongoing savings from their solar investment. 

These business solar incentives in Connecticut help reduce both upfront and long-term costs, making solar more viable for organizations of all sizes.

Massachusetts: 

Key Programs & Incentives:

• Solar Massachusetts Renewable Target (SMART) Program:
  Offers long-term per-kWh payments with additional incentives for battery storage and low-income project deployment. Additional incentive “adders” are available for projects that include energy storage, serve low-income customers, or utilize solar canopies, enhancing the financial benefits for such installations. Businesses are encouraged to act promptly to secure higher incentive rates available in the earlier blocks of the program.​

• Net Metering:
  Businesses receive retail-rate credits for excess solar generation—one of the most generous policies in the region. Recent policy updates have expanded net metering caps and enabled the transfer of net metering credits between utilities, providing greater flexibility for commercial solar facilities. This policy framework ensures that businesses can maximize the financial returns from their solar investments.​
  
  
• Tax Exemptions:
  Full sales and property tax exemptions on solar projects make Massachusetts extremely solar-friendly. These exemptions reduce the upfront and long-term costs of solar investments, making returns more attractive. As a result, Massachusetts ranks among the top states for commercial solar adoption.
  
  

Standout Feature:
Massachusetts provides long-term financial certainty for commercial solar systems, especially mid- to large-scale installations.

New York: 

Key Programs & Incentives:

• NY-Sun Commercial & Industrial Program:
  Through NYSERDA, businesses receive upfront, capacity-based incentives tailored by region and system size. This structure encourages timely participation, as incentives decrease as more capacity is installed within each block.
  
  
• Remote Net Metering:
  Businesses can apply solar credits from one site to offset electric bills at another—a major plus for multi-site operations. This flexibility is particularly beneficial for organizations with multiple facilities, enabling them to optimize energy savings across various sites.
  
  
• Additional Programs:
  Grant funding, low-interest loans, and occasional tax credits provide a rich ecosystem for commercial solar adoption. New York State offers sales and property tax exemptions for solar energy systems, reducing both upfront and long-term costs.
  
  

Why It’s Appealing:
New York’s flexible options and state-backed support make it a top destination for companies with complex energy needs.

New Jersey: Competitive and Evolving Incentive Landscape

Key Programs & Incentives:

• Successor Solar Incentive (SuSI) Program:
  Commercial projects earn SREC-IIs (Solar Renewable Energy Certificates) for each MWh produced, creating an ongoing revenue stream. These certificates can be sold to utilities, providing a steady cash flow in addition to energy savings. The program supports a predictable investment outlook for businesses going solar.
  
  
• Net Metering:
  New Jersey offers full retail-rate net metering, allowing businesses to significantly cut or eliminate electricity bills. Surplus energy sent back to the grid earns full credit, which can be applied to future bills. This policy improves payback periods and enhances the economic case for solar installations.
  
  
• Tax Benefits:
  Commercial solar systems in NJ enjoy both sales and property tax exemptions, easing the financial burden of installation. These exemptions help reduce both initial and ongoing ownership costs. They make large-scale projects more financially feasible for small and medium-sized enterprises.
  
  

Bonus:
New Jersey is ramping up its clean energy commitment with new incentives on the horizon, especially for community solar and storage integration.

Final Thoughts

Connecticut has taken meaningful steps to support commercial solar adoption. Through programs like NRES and strong Connecticut commercial solar tax incentives, businesses can unlock serious savings. However, states like Massachusetts, New York, and New Jersey currently offer expansive benefits, especially in terms of long-term revenue and scalability.

Still, business solar incentives in Connecticut—including property and sales tax exemptions—make it a viable and rewarding market. Whether your business is in manufacturing, retail, healthcare, or education, leveraging these solar tax incentives for Connecticut businesses can significantly lower operational costs.
