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 Mississippi averaged 13.39¢ per kilowatt-hour in 2024, 37th of 51 and below the national average of 16.48¢. Retail electricity is cheaper than most of the country, which lengthens payback because each kilowatt-hour you avoid buying is worth less. Prices and adoption across all 51.
System size and consumption
The average Mississippi system was 5.5 kW in 2024, ranking 46th of 51. Households consumed an average of 13,871 kilowatt-hours a year (2nd 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
Form EIA-861 records no third-party-ownership split for the 1,789 systems counted in Mississippi in 2024. With a market this size the schedule frequently suppresses the split, so we publish nothing rather than infer it. Ask any company directly whether it is selling you ownership or a lease or PPA — the distinction decides who claims the incentives.
Battery attachment
0.61% of Mississippi solar systems were paired with a battery in 2024, 33rd of 51 — 11 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.
Where the market is going
Mississippi added 608 systems in 2024 and has grown at 28.3% a year over five years, 20th of 51. Where growth has turned.
Solar companies and licensing in Mississippi
We found no dedicated state licence register for solar work in Mississippi, 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 1,789 systems in the state and adoption 47th of 51, you are working in a market where a search for "Mississippi 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 Mississippi have solar?
1,789 residential net-metered systems were recorded in Mississippi in 2024, against 1,340,459 residential electricity accounts — 0.13% of households, 47th of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in Mississippi?
The average net-metered residential system in Mississippi was 5.5 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 Mississippi add batteries to solar?
0.61% of Mississippi systems were paired with storage in 2024, 33rd of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is Mississippi a good state for solar?
On the measures we can compute: residential electricity averages 13.39¢/kWh (37th of 51), households use 13,871 kWh a year (2nd of 51), and 0.13% have installed a system (47th 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.
