Connect your solar electric power safely into Eversource’s electric grid and produce clean energy for your home or business.

Solar and other renewable energy sources can help you reduce your energy bill and your carbon footprint. The information below provides a general overview and answers to our most frequently asked questions about selecting, connecting and maintaining your solar energy system.

This information is provided as a service to our customers. Please consult with your installer or lender for important technical or economic considerations unique to your project.

Please note, Eversource is happy to provide usage or other requested information directly to your solar contractor. For security purposes, please contact us first and provide your consent for that information to be shared.

Also, please use caution and do not provide your account number to a contractor or another third-party, or allow them to request your account number. With this information, it is possible to view confidential account information, usage or other data. 


Solar photovoltaic (PV) generation systems connect directly to your electric service and interface seamlessly with Eversource’s electric system. Solar panels work best in locations that are exposed to the sun with minimal shading for at least six hours a day.

Solar PV systems are composed of individual solar cells configured onto a solar panel. When sunlight shines on a solar cell, the cell absorbs the light’s energy and produces a flow of electrons, known as direct current (DC) electricity.

Because appliances and machinery operate on alternating current (AC), a device called an inverter converts the DC electricity to the AC power necessary to power your home or business. 

Getting Started

Improve Your Energy Efficiency: If you’re looking to save energy and money, improving the energy efficiency of your home or business is an important consideration before going solar.

Energy efficient actions such as replacing old, inefficient appliances can reduce your overall energy usage, ultimately reducing the size of the solar generation system you’ll need and potentially saving you thousands of dollars in up-front costs.

Select a Contractor: Once you have determined that installing a solar electric system is the right decision for you, you will need to select a solar electric contractor to complete your solar installation.

Once selected, your contractor will help you complete and submit all necessary applications and project plans to Eversource to safely connect your new solar PV system to Eversource’s grid. View a list of qualified solar contractors in your area at Solar Energy Industries Association or the North American Board of Certified Energy Practitioners website.

Design, Construct and Energize: The process of constructing and connecting your solar PV project will vary based on project specifics, but typically consist of the following stages:

  • Submit an application with Eversource (online option is available)
  • Eversource will complete a review of the application
  • Your contractor will install your generator
  • You or your contractor must provide written notice to Eversource when the electrical inspection has been completed.
  • Eversource may request to witness the commissioning of the generator system
  • If needed, Eversource will install a bi-directional meter (net meter) that allows us to measure the amount of energy used, as well as any excess energy that is produced by your system
  • Eversource will send you an approval letter to connect and safely operate your generator

Please note that you should not begin to generate power before your new meter has been installed and you have received permission to energize.

Financial Investment and Incentives

Choosing a solar PV system that is sized correctly for your home is an important first step in determining your overall financial investment. When sizing your system, consider your usage needs and energy goals.

The up-front cost of a solar PV system will also depend on other factors, equipment options, location, labor costs and local permitting costs. In addition, the decision to purchase the system outright, obtain a loan or lease the system will affect the total up-front cost.

Please check with your contractor, bank or lender for available financing options in your area. Buying a solar PV system from an approved contractor or manufacturer means you would pay for it up-front or finance your purchase through a bank loan.

As the system’s owner, you would be responsible for all maintenance or repair costs outside of the warranty period. You may also be eligible for additional tax incentives.

Leasing provides for a lower upfront financial investment and allows you to rent the system for a set period of time. Generally, you would be responsible to pay a fixed monthly amount, regardless of how much energy the system produces each month.

Similarly, in a Power Purchase Agreement (PPA) a third-party would own and maintain the system on your behalf. You would be responsible to pay for the electricity generated at a rate per kilowatt hour (kWh), as specified in your agreement.

State and federal incentives are available to help reduce the cost of installing a solar or renewable energy system. The Solar Outreach Partnership has a helpful guide to federal tax credits for residential customers installing solar panels. You can also visit the Database of State Incentives for Renewables & Efficiency website for more information on available programs and eligibility requirements in your state. Please consult your personal tax advisor to determine if you qualify for these or any other tax incentives.

Billing & Net Metering

The Eversource Net Metering program is a renewable rate program available to customers using their own renewable energy source to generate electricity. Each state has established guidelines for net metering. More information is available in the Builders & Contractors section.


Your Meter: Eversource will install a bi-directional or net meter after your solar construction has been approved. This meter allows Eversource to measure the amount of energy used, as well as any excess energy that is produced by your system.  

For additional information on how to read your net meter, please read our Frequently Asked Questions document.

Your Bill: You will remain an Eversource customer after installing a solar or other renewable energy system and will continue to receive a monthly bill. Your bill will vary based on your usage and the amount of energy your system produces, but at minimum, will include a customer service charge that allows you to be connected to the electric grid and the net difference of your energy usage and the amount of energy produced by your system.

You may also receive a separate monthly bill from the owner of your system if you have elected a third-party lease agreement or Power Purchase Agreement (PPA).

Other Considerations

Moving: If you decide to move and have purchased a solar PV system up-front, typically, the value of the system is incorporated into the purchase price of your home. If you have signed a lease agreement or PPA, you may be able to transfer your agreement to the new homeowner or buy out the remainder of your contract. Please consult your third-party or lender for specific details.

Informing Others of Your Plan to Install Renewable Generation: We recommend that you inform your insurance company and your third-party electric supplier (if applicable) about any existing or proposed generation. Please refer to your contract terms and conditions before moving forward with the decision to install solar or other renewable generation.

Power Outages: Unless you have a back-up battery system installed, you will not have power during an outage.
