What the adoption figure means
One of the least developed rooftop markets in the country. Expect few installers, long lead times, and permitting offices with little solar experience.
Residential electricity in Indiana averaged 14.77¢ per kilowatt-hour in 2024, 27th of 51 and below the national average of 16.48¢. Prices are close to the national middle, so the export rate your particular utility offers usually decides the outcome rather than the retail rate. Prices and adoption across all 51.
System size and consumption
The average Indiana system was 8.69 kW in 2024, ranking 8th of 51. Households consumed an average of 10,814 kilowatt-hours a year (25th 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
0.0% of Indiana systems were third-party owned in 2024 — leased or under a power purchase agreement rather than owned by the householder. That is 36th of 51.
Outright ownership dominates, so purchase and loan offers will make up most of what you see. Who claims the federal credit · ownership across all 51.
Battery attachment
5.69% of Indiana solar systems were paired with a battery in 2024, 9th of 51 — 629 paired systems.
Attachment is well above average, so storage is a normal part of a quote here rather than an upsell. Attachment across all 51 · does a battery belong in your project.
Where the market is going
Indiana added 657 systems in 2024 and has grown at 25.4% a year over five years, 24th of 51. Where growth has turned.
Solar companies and licensing in Indiana
We found no dedicated state licence register for solar work in Indiana, so we publish no company counts rather than guessing. That is not evidence of light regulation — electrical work is frequently licensed at state or local level even where solar is never named separately.
It does have a practical consequence here. With 11,045 systems in the state and adoption 45th of 51, you are working in a market where a search for "Indiana solar licence" will often return nothing useful, and where the company quoting you may be travelling in from out of state. Ask which licence they hold, in which state, and confirm it with that issuing authority rather than accepting a licence number on a proposal. What to do when the search comes back empty.
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.
None of these figures is an estimate for your property. What to work through before you talk to anyone.
Common questions
How many homes in Indiana have solar?
11,045 residential net-metered systems were recorded in Indiana in 2024, against 3,056,216 residential electricity accounts — 0.36% of households, 45th of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in Indiana?
The average net-metered residential system in Indiana was 8.69 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 Indiana add batteries to solar?
5.69% of Indiana systems were paired with storage in 2024, 9th of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is Indiana a good state for solar?
On the measures we can compute: residential electricity averages 14.77¢/kWh (27th of 51), households use 10,814 kWh a year (25th of 51), and 0.36% have installed a system (45th 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.
