What state produces the most solar power

Executive summary
California produces the most solar power in the United States, by both installed photovoltaic capacity and by the largest share of electricity generation from solar in recent data; the Golden State accounted for roughly 23.5% of U.S. solar generation in January 2026 and had by far the largest cumulative PV capacity as of mid‑2024 (over ~48 GW) [1] [2]. That dominance is real but narrowing: Texas and several Sun Belt states have been the fastest growers in capacity and generation, so leadership in annual totals reflects both legacy installations and continuing buildouts [2] [3].
1. California’s clear quantitative lead—capacity and generation
Multiple industry trackers put California at the top: Statista reports California had the greatest cumulative solar PV capacity—over 48 gigawatts as of June 2024—making it the largest single‑state fleet of solar panels in the country [2], and Choose Energy’s January 2026 snapshot shows California produced 23.5% of U.S. solar electricity for that month—23.5% of 32,027 thousand MWh—underscoring that California still delivers the biggest share of actual solar generation [1]. Independent aggregators of installation counts likewise place California far ahead in megawatts installed and number of installations [4].
2. Why capacity and generation both matter (and sometimes diverge)
Installed capacity (megawatts or gigawatts of panels) measures potential, while generation (megawatt‑hours produced) measures what panels actually contributed over time; California tops both metrics in the available reporting, but the gap is not immutable—capacity growth elsewhere can boost generation even if total statewide capacity remains lower [2] [1]. Moreover, small‑scale rooftop and community solar versus utility‑scale farms are counted differently in some datasets; comprehensive totals that include distributed generation show higher U.S. solar generation totals and can shift rankings slightly depending on methodology [5].
3. The challengers: Texas, Florida and rapid Sun Belt growth
Texas has been the fastest accelerator in recent years, adding thousands of megawatts of new capacity—Canary Media reports Texas added nearly 5,000 MW in one recent year, a 37% increase from 2022—so its share of generation is rising even as it remains behind California overall [3]. Florida and other Sun Belt states have also seen big utility‑scale builds and policy shifts that push up new installations, and some reporting notes Florida recently surpassed California on new utility‑scale installations in a specific period [6]. These dynamics mean California’s numerical lead is durable today but faces growing competition as new projects come online [3] [6].
4. Policy, incentives and reporting quirks that shape apparent rankings
State policies—tax exemptions, net metering, interconnection rules and incentive programs—drive where rooftop and commercial solar proliferate, so counts of installations and capacity reflect policy as much as sunshine [7]. Some public trackers compile EIA monthly generation data; Choose Energy’s January 2026 report explicitly uses EIA figures to rank states [1]. Caution: not all states report every month (Choose Energy noted several states didn’t report solar production in certain months), and some outlets mix timeframes or include only utility‑scale numbers, which can affect apparent leaders [1].
5. Bottom line and limitations of available reporting
Based on the supplied reporting, California is the top solar‑producing state by installed PV capacity and by recent measures of generation [2] [1]. That conclusion is supported across industry trackers and market summaries, though rapid capacity growth in Texas and parts of the Sun Belt is closing the gap and different data definitions (utility‑scale vs total solar, monthly vs annual snapshots) can alter short‑term rankings [3] [5]. The sources supplied do not provide a single harmonized annual table of state‑by‑state generation for 2024–2026, so precise percentages beyond the cited snapshots depend on which dataset and timeframe are used [1] [2] [5].
