In 50 words: Solar power in the US in 2026 totals roughly 210 GW of installed capacity, generates about 8% of US electricity, and is adding 35–45 GW per year — the largest source of new generation in the country. This guide compiles the actual 2026 US solar power statistics by segment, state, and trajectory, with the underlying drivers explained.
US solar power statistics are now big enough to be confusing — figures vary by source, date, and definition of "solar." This guide compiles the cleanest 2026 numbers on installed solar power capacity, annual generation, growth rate, segment breakdown, and state leadership, sourced from EIA, SEIA/Wood Mackenzie, BloombergNEF, and NREL. The goal: one place to find the working solar power statistics for the US, with the methodology footnotes.

1. Total US solar power capacity 2026
| Solar power capacity (Q1 2026, US) | GW |
|---|---|
| Total installed solar power capacity (operating) | 210–225 GW |
| Utility-scale solar power | 145–155 GW |
| Commercial + industrial solar power | 30–35 GW |
| Residential solar power | 30–35 GW |
| Community solar power | 8–10 GW |
These US solar power statistics come from the most recent EIA EPM and SEIA quarterly reports, reconciled. The aggregate total is roughly 210–225 GW operating in Q1 2026, with solar power growing toward 250 GW by year-end.
For context: total US grid capacity is roughly 1,300 GW across all sources. Solar power is 16–17% of US installed capacity in 2026 but a smaller share of generation (next section) because of its lower capacity factor.
2. US solar power generation as % of electricity
Solar power accounted for roughly 8% of total US electricity generation in 2026 — up from 5% in 2023 and roughly 0.5% in 2015.
| Year | Solar power share of US electricity generation |
|---|---|
| 2015 | 0.5% |
| 2018 | 1.5% |
| 2020 | 2.3% |
| 2022 | 3.4% |
| 2023 | 5.0% |
| 2024 | 6.0% |
| 2025 | 7.2% |
| 2026 | 8.0–8.5% |
The growth in US solar power generation share is meaningfully faster than the growth in solar power capacity share — because new utility-scale solar farms have higher capacity factor (28–32%) than the older residential installations that dominate older capacity data.
3. Annual solar power additions: 35–45 GW per year
The 2026 US solar power statistic that matters most for the future is the annual addition rate. The US is now adding 35–45 GW of new solar power capacity per year — by far the largest source of new generation.
| 2026 US new generation additions (by source) | GW |
|---|---|
| Solar power | 35–45 |
| Storage (BESS) | 18–25 |
| Onshore wind power | 8–12 |
| Natural gas | 3–6 |
| Offshore wind power | 1–3 |
| Nuclear | 0 (no new builds) |
| Coal | -10 to -15 (net retirements) |
Solar power additions in 2026 are more than 4x the next single source (storage). The IRA's full-stack incentive structure (45X manufacturing credit + ITC/PTC + transferability) is the underlying driver, plus declining hardware costs and broadening corporate offtake demand.
4. US solar power by segment
| Segment | Q1 2026 share of US solar power capacity | What it is |
|---|---|---|
| Utility-scale (>5 MW) | 65–70% | Solar farms |
| Commercial + industrial | 12–16% | Rooftop or carport at businesses, schools, governments |
| Residential | 14–17% | Homeowner residential solar systems |
| Community solar | 4–5% | Subscriber-based ground-mount in supportive states |
The fastest-growing segment in 2026 by % growth rate is residential (driven by California NEM 3.0 battery pairings + state incentive expansions in NY/MA/NJ). The fastest-growing in absolute GW is utility-scale (driven by hyperscaler corporate PPAs in Texas, Virginia, Georgia).
5. Top 10 US states for solar power
| Rank | State | Operating solar power capacity (Q1 2026) | Why |
|---|---|---|---|
| 1 | Texas | ~30 GW | ERCOT competitive market, vast land, hyperscaler demand |
| 2 | California | ~45 GW | Largest installed base; mix of residential + utility |
| 3 | Florida | ~14 GW | FPL utility-scale procurement |
| 4 | North Carolina | ~10 GW | Mature utility solicitations |
| 5 | Arizona | ~9 GW | High irradiance + data center load |
| 6 | Nevada | ~7 GW | Federal land + Mojave irradiance |
| 7 | Georgia | ~6 GW | Georgia Power + Qcells co-location |
| 8 | Virginia | ~5 GW | Data center driven; corporate PPAs |
| 9 | New Jersey | ~5 GW | Aggressive state solar carve-out |
| 10 | Massachusetts | ~5 GW | SMART program + community solar |
California has the largest installed solar power capacity but is no longer the fastest growing — that's Texas (utility-scale) and the Southeast. The CA market has matured; NEM 3.0 reform slowed new residential solar power additions in late 2023–2024 before stabilizing on solar + battery pairings.
6. Solar power statistics: jobs and economic impact
The US solar power industry employed ~340,000 workers in 2026, up from ~250,000 in 2020. Breakdown:
| Job category | 2026 employment (approx.) |
|---|---|
| Installation (residential + commercial + utility) | 200,000 |
| Manufacturing (modules, inverters, racking) | 60,000 |
| Project development | 25,000 |
| Operations + maintenance | 30,000 |
| Sales + admin | 25,000 |
Manufacturing jobs in particular have grown rapidly under IRA's 45X advanced manufacturing credit — Qcells' Dalton expansion alone added ~2,500 jobs. First Solar's expansion across AZ, OH, AL, IN added similar numbers.
US solar power industry revenue in 2026: roughly $95–$110 billion across installation, equipment manufacturing, project development, and O&M.
7. Solar power vs. other generation sources
| Source | 2026 US capacity (GW) | 2026 US share of generation |
|---|---|---|
| Natural gas | 540 | 41% |
| Coal | 175 | 14% |
| Nuclear | 95 | 18% (high capacity factor) |
| Wind power | 155 | 11% |
| Hydroelectric | 80 | 6% |
| Solar power | 215 | 8% |
| Other (biomass, geothermal, oil) | 40 | 2% |
US solar power has now overtaken hydroelectric in generation share for the first time (~8% vs ~6%). Solar power capacity exceeds wind power, but wind still generates more because of higher capacity factor. We compared the two technologies in solar power vs wind power 2026.
8. Solar power trajectory: 2027–2030 forecasts
| Year | Forecasted US solar power capacity (GW) | Forecasted % of US electricity |
|---|---|---|
| 2026 (actual + projection) | 215–225 | 8% |
| 2027 (forecast) | 255–270 | 10% |
| 2028 (forecast) | 295–315 | 12% |
| 2029 (forecast) | 335–360 | 14% |
| 2030 (forecast) | 380–420 | 16–18% |
These US solar power statistics forecasts assume IRA incentives stay in force, transformer / interconnection capacity expands at current trend, and module supply chains hold. Downside scenarios — IRA repeal, severe tariff escalation, interconnection backlog worsening — could shave 50–80 GW off these numbers.
The trajectory is solid through 2027. Beyond that, the binding constraint shifts from technology cost (which keeps falling) to grid infrastructure (transmission, transformer manufacturing) and permitting.
