What the adoption figure means
One of the most established rooftop markets in the country: a deep installer bench, and permitting offices that process these applications routinely.
Residential electricity in Connecticut averaged 28.75¢ per kilowatt-hour in 2024, 4th of 51 and above the national average of 16.48¢. Among the most expensive residential electricity in the country, which is the strongest single reason adoption rises: what you avoid paying is the value of every kilowatt-hour you use on site. Prices and adoption across all 51.
System size and consumption
The average Connecticut system was 7.71 kW in 2024, ranking 18th of 51. Households consumed an average of 8,335 kilowatt-hours a year (35th of 51) — the figure a system here is sized against.
Size your own system from your own kilowatt-hours, not from this average — how to do that.
Who owns the systems
53.8% of Connecticut systems were third-party owned in 2024 — leased or under a power purchase agreement rather than owned by the householder. That is 3rd of 51.
Leases and power purchase agreements are the default way solar is sold here. Read any agreement closely before assuming you will own what goes on your roof. Who claims the federal credit · ownership across all 51.
Battery attachment
0.65% of Connecticut solar systems were paired with a battery in 2024, 32nd of 51 — 677 paired systems.
Attachment is around the middle — storage is a live option here rather than a default. Attachment across all 51 · does a battery belong in your project.

Method
Figures are computed by HyreSolar from the Form EIA-861 2024 annual files — net-metered residential systems only, penetration counted against residential accounts, sizes as means. EIA publishes the inputs, not these ratios. Full methodology and the underlying CSV.

Common questions
How many homes in Connecticut have solar?
103,824 residential net-metered systems were recorded in Connecticut in 2024, against 1,552,746 residential electricity accounts — 6.69% of households, 6th of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in Connecticut?
The average net-metered residential system in Connecticut was 7.71 kW in 2024, against a national average of 6.74 kW. Your own system should be sized from twelve months of your kilowatt-hours and your usable roof, not from a state average.
Do people in Connecticut add batteries to solar?
0.65% of Connecticut systems were paired with storage in 2024, 32nd of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is Connecticut a good state for solar?
On the measures we can compute: residential electricity averages 28.75¢/kWh (4th of 51), households use 8,335 kWh a year (35th of 51), and 6.69% have installed a system (6th of 51). Retail price and export rules move the answer far more than sunshine does, and both are set by your specific utility rather than by the state.
