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 Hawaii averaged 42.86¢ per kilowatt-hour in 2024, 1st 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 Hawaii system was 5.4 kW in 2024, ranking 48th of 51. Households consumed an average of 5,938 kilowatt-hours a year (51st 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
21.8% of Hawaii systems were third-party owned in 2024 — leased or under a power purchase agreement rather than owned by the householder. That is 16th of 51.
Third-party ownership is common, so leases and PPAs will be presented alongside purchase. Who claims the federal credit · ownership across all 51.
Battery attachment
18.24% of Hawaii solar systems were paired with a battery in 2024, 3rd of 51 — 17,953 paired systems.
Among the highest attachment rates in the country, which normally points to poor export compensation, unreliable supply, or both. Attachment across all 51 · does a battery belong in your project.
Where the market is going
Hawaii added 4,776 systems in 2024 and has grown at 4.4% a year over five years, 50th of 51. Where growth has turned.
Solar companies and licensing in Hawaii
We checked 31 Hawaii solar companies against the state licence register. 0.0% did not hold a current licence at the time of checking .

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 Hawaii have solar?
98,418 residential net-metered systems were recorded in Hawaii in 2024, against 446,512 residential electricity accounts — 22.04% of households, 1st of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in Hawaii?
The average net-metered residential system in Hawaii was 5.4 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 Hawaii add batteries to solar?
18.24% of Hawaii systems were paired with storage in 2024, 3rd of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is Hawaii a good state for solar?
On the measures we can compute: residential electricity averages 42.86¢/kWh (1st of 51), households use 5,938 kWh a year (51st of 51), and 22.04% have installed a system (1st 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.
