What the adoption figure means
A middling market — neither early nor late. Expect a reasonable choice of installers without the depth of the coastal markets.
Residential electricity in Missouri averaged 12.91¢ per kilowatt-hour in 2024, 38th 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 Missouri system was 9.15 kW in 2024, ranking 4th of 51. Households consumed an average of 12,007 kilowatt-hours a year (17th 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 Missouri systems were third-party owned in 2024 — leased or under a power purchase agreement rather than owned by the householder. That is 37th 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
2.53% of Missouri solar systems were paired with a battery in 2024, 16th of 51 — 760 paired systems.
Attachment runs above the national middle, suggesting storage often earns its place. 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 Missouri have solar?
30,022 residential net-metered systems were recorded in Missouri in 2024, against 2,933,914 residential electricity accounts — 1.02% of households, 33rd of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in Missouri?
The average net-metered residential system in Missouri was 9.15 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 Missouri add batteries to solar?
2.53% of Missouri systems were paired with storage in 2024, 16th of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is Missouri a good state for solar?
On the measures we can compute: residential electricity averages 12.91¢/kWh (38th of 51), households use 12,007 kWh a year (17th of 51), and 1.02% have installed a system (33rd 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.
