Is Solar Worth It in Connecticut in 2026?

Is solar worth it in Connecticut? For the right home, it can be very compelling. This guide explains how the state's solar tariff and battery incentives work, and when HVAC or efficiency upgrades should come first.

Connecticut homeowners have good reason to pay attention to energy costs.

Electricity prices can be high. Homes need both winter heating and summer cooling. And major storms have made backup power an important concern for many families.

That makes solar attractive.

But it doesn't make solar automatically right for every home.

That could be solar.

It could be HVAC or efficiency improvements.

It could be battery storage.

For some homeowners, the answer may eventually be all three.

Why Connecticut Can Be a Strong Solar Market

Connecticut isn't known for desert sunshine.

It doesn't need to be.

Solar panels make electricity from available sunlight. Systems are judged on how much they produce over a full year, not on one cloudy winter afternoon.

A Connecticut home may be worth evaluating for solar when it has:

• Good roof exposure
• Limited shading
• A roof with substantial useful life remaining
• Meaningful annual electricity usage
• Suitable utility interconnection
• Access to Connecticut's current residential solar tariff
• Reasonable installation economics
• Plans for longer-term homeownership

One of Connecticut's biggest advantages is not simply sunlight.

It is the state's structured program that pays homeowners for their solar power.

What Replaced Connecticut Net Metering?

For new systems, Connecticut's old net-metering program (credit for extra solar power you send to the grid) was replaced. The new program is the Residential Renewable Energy Solutions Program, commonly called RRES.

RRES launched in January 2022. Eversource Energy and United Illuminating run it. Connecticut's Public Utilities Regulatory Authority, or PURA, oversees it.

For 2026, qualifying homeowners can choose between two main ways to get paid:

Buy-All or Netting.

That's an important decision because the two options work differently.

How Does the Connecticut Netting Option Work?

Under the RRES Netting tariff, solar electricity generally serves the home first.

If the system makes more power than the home needs, the extra goes out to the grid.

United Illuminating currently says exported energy under Netting is credited at the retail rate used by the program.

This setup may appeal to homeowners who mainly want solar to cut the amount of electricity they buy.

In practical terms:

Solar produces → home consumes → excess goes to the grid.

That's similar to traditional net metering, although Connecticut's RRES program has its own tariff rules.

One of those rules matters a lot in 2026. New Netting customers pay a Solar Energy Adjustment of 4.02¢ per kWh on total solar production. Any Netting savings estimate should include it.

How Does the Buy-All Option Work?

The Buy-All tariff is different.

Under Buy-All, all qualifying solar production is metered separately. It is sold to the utility at a PURA-approved tariff rate.

The homeowner keeps buying the power the home uses through the normal electric account.

For systems applying during 2026, the currently published Buy-All base rate is $0.3289 per kWh (kilowatt-hour, the unit on your bill). That rate applies to both Eversource and UI customers. Extra adders may be available for qualifying low-income customers and customers in economically distressed municipalities.

The approved tariff term is generally locked in for 20 years once the project is accepted.

That's a meaningful feature.

But whether Buy-All or Netting is better depends on the household.

Which Is Better: Buy-All or Netting?

There isn't one answer for everyone.

A homeowner should consider:

• Electricity usage
• Solar system production
• Current electricity rates
• Expected future rates
• Daytime consumption
• Financing
• Eligibility for additional RRES adders
• Planned ownership period

Buy-All creates predictable value based on production.

Netting more directly offsets household electricity use.

The best option should be modeled using the actual home's energy profile.

Does Connecticut Still Have a Federal 30% Solar Tax Credit?

Not for a new residential installation completed in 2026.

The former Residential Clean Energy Credit applied to qualifying property installed through December 31, 2025. It is no longer available for property placed in service after that date.

This is important because many solar websites still mention the old 30% credit.

Connecticut homeowners looking at a 2026 project should not assume that tax benefit exists.

Instead, the economics should be based on:

• Actual system cost
• RRES compensation
• Electricity savings
• Financing cost
• Roof condition
• Expected production
• Ownership period

Do Electricity Rates Still Matter for Solar in Connecticut?

Connecticut's electricity rates can be a major part of the solar conversation. But homeowners should work from current numbers.

PURA approved new rate adjustments effective May 1, 2026 through April 30, 2027. They lowered certain rate parts for both Eversource and United Illuminating customers.

PURA estimated the changes cut an average Eversource home bill by roughly $30 per month. It estimated an average UI bill dropped by roughly $34 per month compared with the prior rates.

That's a good reminder:

What About HVAC?

Connecticut homes deal with both heating and cooling.

Depending on the equipment, electricity may be used by:

• Central air conditioning
• Heat pumps
• Electric resistance heat
• Electric water heating
• Dehumidification
• Older mechanical systems

An older HVAC system may be causing high electricity use. If so, replacing or improving it may cut the amount of power the home needs.

That can change the solar system size.

Imagine a home using 16,000 kWh annually.

Say HVAC and efficiency work cuts that to 12,500 kWh. A solar system designed around the original usage may end up larger than needed.

Sometimes the better sequence is:

Connecticut Makes Battery Storage Especially Interesting

This is where Connecticut really stands out.

The state runs Energy Storage Solutions, a statewide battery incentive program for qualifying Eversource and UI customers.

The Connecticut Green Bank, Eversource and UI run the program, with PURA oversight.

For residential customers applying under the structure effective April 1, 2026, the program currently provides:

• $30 per kWh enrollment incentive for standard residential customers
• $130 per kWh for qualifying Grid-Edge customers
• Performance incentives based on battery participation during grid events

Standard residential performance incentives are currently listed at $300 per kW per year over a 10-year term. Certain underserved and low-income customers may qualify for higher performance rates.

That can change the battery conversation in a big way.

What Is a Grid-Edge Customer?

Some customers lose power more often, or for longer, than average. Connecticut's storage program gives these customers extra upfront support.

Those customers can qualify for the higher Grid-Edge enrollment incentive.

For a homeowner with a history of outages, that's worth checking.

What Does the Battery Program Ask in Return?

The storage program isn't simply handing homeowners money for installing batteries.

Enrolled batteries can be called on to send power when the grid is under high demand.

Beginning April 1, 2026, Connecticut shifted more of the incentive value toward actual performance over time.

Residential performance payments are based on the battery's average contribution during qualifying dispatch events (times the grid calls on batteries).

That means battery economics depend partly on:

• Battery size
• System configuration
• Customer participation
• Actual battery performance
• Eligibility category

A headline incentive number should not be treated as guaranteed lifetime revenue.

Solar vs. Battery: Which Matters More?

They solve different problems.

Solar generates electricity.

Battery storage keeps electricity available for later.

If your main goal is buying less power from the grid, solar may deserve priority.

If your main concern is storm-related outages, battery storage may deserve more attention.

If both matter, solar plus storage may make sense.

Solar Alone Does Not Automatically Mean Backup Power

This is an important difference.

A standard grid-connected solar system typically shuts down when the utility grid fails.

To keep running during an outage, the home needs equipment built for backup operation.

Battery storage is commonly part of that system.

So if you are thinking about solar because of storm outages, the right question is not:

So, Is Solar Worth It in Connecticut?

It can be very compelling.

Connecticut offers homeowners:

• A structured 20-year residential renewable tariff
• Buy-All and Netting options
• Potential additional RRES adders
• Strong battery incentives
• Meaningful electricity costs
• A mature clean-energy market

But none of those features replace a proper home-energy analysis.
