Half the world's solar sits in one country — and every country polygon hides its own concentration

Asked:“Solar power at three zoom levels: installed solar capacity by country worldwide, then within India by state, then within the United States by state. One map per level, each naming its leading regions with capacity in GW, and say how much of the world total the top level hides.”

The 2025 world compilation reports 2,383 GW of cumulative solar PV. China leads at 1,200 GW (50.4%), then the United States at 210 GW and India at 135 GW. The two countries unpacked below — the U.S. and India — hold 345 GW combined, 14.5% of the world total: that is the share of world capacity whose state-level distribution the country map hides. Every country polygon, including China's 50.4%, hides similar subnational concentration; this report reveals only India and the U.S.

World — cumulative solar PV by country

Snapshot 2025 · leader set of 14 countries from a 2025 IRENA-based compilation, not all countries · GW

Grey countries are not in the extracted leader set — they are unmapped, not zero.

Colour: installed capacity, pale solar yellow → deep orange (square-root scale). Grey = no extracted row.

India — solar by state, all categories

Snapshot November 2025 · ground-mounted + rooftop + hybrid + off-grid · All-India total 132.85 GW · GW

The source lists 14 states individually; smaller states and territories are grouped as “Others” (3.47 GW) and cannot be mapped separately.

United States — solar by state, partial coverage

SEIA state profiles, MWdc converted to GW · 12 states resolved · newest dated profile per state

Structured retrieval resolved a capacity for only 12 of the SEIA profiles, so this panel is partial and implies no all-state ranking; the national leaders California and Texas are among the unresolved profiles.

The zoomed levels — U.S. 210 GW + India 135 GW — are (210 + 135) / 2,383 = 14.5% of world capacity whose within-country pattern the world map conceals. solardataatlas.com
India's top two states alone, Rajasthan (35.91 GW) and Gujarat (24.79 GW), hold 46% of India's 132.85 GW. vasudha-foundation.org
Among resolved U.S. states, Georgia leads at 7.68 GW, ahead of New Jersey (5.86 GW), Wisconsin (3.5 GW), Minnesota (3.28 GW) and Maryland (3.16 GW). seia.org
Definitions differ slightly by level: world figures are cumulative PV; India's total spans ground-mounted, rooftop, hybrid and off-grid; U.S. figures are SEIA MWdc — close, not perfectly harmonized. solardataatlas.com

Three snapshots: world 2025 (IRENA-based compilation, cumulative PV, 14-country leader set — unlisted countries are unmapped, not zero; China's 1,200 GW is taken from the source page's headline figure); India November 2025 (Vasudha Foundation table, 14 states listed individually, “Others” 3.47 GW and All-India 132.85 GW excluded from polygons); United States from SEIA state profiles (MWdc ÷ 1,000, 12 of ~50 profiles resolved, newest dated profile kept per state, no interpolation of missing states). 40 mapped rows in total.
