CT Net Metering Is Changing Jan. 1: Lock In Your Solar Savings Now
Earthlight Technologies • August 7, 2026
If you're a Connecticut homeowner who has been on the fence about solar, this is the year the fence disappears. Starting January 1st, Eversource is expected to change the rules around net metering — and for most solar homeowners, that means giving up roughly 7% of the energy savings they're counting on. The homeowners who lock in today's rules before that date will keep them for the next 20 years. The ones who wait will be stuck under the new rules for just as long.
This isn't a minor tweak. Over the life of a typical solar system, that 7% difference can add up to $10,000 or more in lost savings. Below, we break down what's actually changing, why the timing matters so much right now, and what Connecticut homeowners should do before the deadline hits.
What Is Net Metering, and Why Does It Matter?
Net metering is the mechanism that lets solar homeowners get credit for the excess electricity their panels generate but don't use right away. When your system produces more power than your home needs — on a sunny afternoon, for example — that extra energy flows back onto the grid, and your utility credits your account for it. Later, when your panels aren't producing enough (at night, or on a cloudy day), you draw from those credits instead of paying full price for grid electricity.
The rate at which that excess energy gets credited is the whole ballgame. Under today's net metering structure, Connecticut homeowners are credited at a rate that makes solar's payback timeline and long-term savings pencil out favorably. That's the rate Eversource is planning to adjust starting January 1st, and it's why we've also covered the broader shift in our Connecticut residential solar program changes for 2026 and our guide to Connecticut's netting tariff.
Why a 7% Cut Adds Up to So Much Money
Seven percent can sound small in isolation, but solar savings compound over the life of a system, which typically runs 25 years or more. A 7% reduction applied every single billing cycle, year after year, doesn't just shave a little off the top — it meaningfully extends your payback period and reduces your total lifetime savings. For many households, that difference works out to $10,000 or more over the system's lifespan, depending on system size and household energy use.
That's the core reason timing matters here in a way it usually doesn't with solar decisions. Most of the time, "when" you go solar is flexible. This time, the rules in place on the day your system is approved and interconnected are the rules that follow you for the next 20 years. Waiting even a few months past January 1st could mean locking in the lower rate for two decades instead of the current one.
How to Lock In Today's Rate Before January 1st
Locking in the current net metering structure isn't just about signing a contract before the deadline — it typically requires your system to be approved and interconnected under the existing rules, which means the process needs to start well before January 1st. Between design, permitting, installation, and utility interconnection, solar projects take time to move through the pipeline, so the homeowners who benefit most are the ones who start now rather than in December.
Our residential solar team can walk you through where your specific timeline stands, what your home would produce and save under today's rules versus the new ones, and what financing options — including PPA and leasing options — make the most sense for your budget.
Why Homeowners Trust Earthlight With This Decision
Since 2008, Earthlight has helped more than 4,000 homeowners across Connecticut, Massachusetts, and Oregon go solar and start saving. We're not a broker connecting you with a subcontractor — our own in-house crews handle design, installation, and ongoing service, so the same team that helps you understand the net metering timeline is the same team installing your system and standing behind it afterward.
Frequently Asked Questions
What is changing with Eversource net metering on January 1st?
Eversource is expected to adjust the net metering credit rate for new solar customers, which effectively reduces the value of the excess energy your system sends back to the grid by around 7% compared to today's structure.
Does this affect homeowners who already have solar installed?
Homeowners who are already interconnected under the current net metering rules are generally grandfathered in for a set period under their existing agreement. The urgency applies to homeowners who haven't yet gone solar or completed interconnection.
How much could the net metering change cost me if I wait?
It depends on your system size and energy usage, but for a typical residential system, the reduced credit rate can add up to $10,000 or more in lost savings over a 20-year period compared to locking in today's rate.
How long does it take to go solar and lock in the current rate?
The timeline includes system design, permitting, installation, and utility interconnection, which can take longer than expected during high-demand periods. Starting the process as early as possible gives you the best chance of locking in today's rules before January 1st.
Is net metering the same in Massachusetts and Oregon?
No, each state and utility has its own net metering structure. This particular change applies to Eversource customers in Connecticut. If you're in Massachusetts, see our net metering guide for Massachusetts homeowners.
