The global installed capacity of large-scale solar power plants has exceeded 1 TW of AC power, according to the consulting company Wiki-Solar. Analysts estimate that, as of today, a total of 23,285 industrial solar power projects have been implemented in 33 leading countries. The aggregate capacity of newly-commissioned facilities in 2025 alone has reached an all-time high, approaching 250 GW of AC power.
China continues to be the largest market for solar, with 5,639 power plants and a total capacity of 446 GW of AC power. It is followed by the United States (3,796 power plants) and India (1,965 power plants) with a total capacity of 162.8 GW and 109.6 GW of AC power, respectively.
Spain and Germany rank fourth and fifth, with 39.3 GW and 25.1 GW of AC power capacity, respectively. Brazil and Japan round out the top ten with 21 GW of capacity each. They are followed by Australia (16.2 GW), France (12.6 GW) and Chile (12.5 GW).
Saudi Arabia leads the way in the Middle East, ranking 12th with 11.9 GW of AC power capacity. South Africa remains the only African country among the 33 largest markets, with 6.2 GW capacity placing it 18th in the ranking.
Wiki-Solar founder Philip Wolfe notes that, with current growth rates, industrial solar generation could become as big as the wind power industry as early as by the end of 2026. When it comes to smaller units (such as rooftop panels on residences and businesses, as well as local systems near consumers), the overall capacity is already significantly higher. According to the International Renewable Energy Agency, global solar power capacity currently stands at about 2.4 TW.
