Global Solar Power

Utility-scale solar farms worldwide, from operating installations to announced projects. Solar is the fastest-growing power source globally, with installed capacity expanding rapidly across every continent. Together with wind, solar generation is central to the green energy transition and the electrification of industry and transport.

Behind the dots

The constraint moved from panels to absorption

Solar added a record 647 GW in 2025, roughly four gigawatts for every one of wind, and its generation passed wind's for the first time; China installed 378 GW of it[2]. Panels are no longer the scarce input anywhere. What is scarce is the system's ability to absorb midday energy.

The absorption problem shows up as prices and curtailment. Spain's day-ahead market spent 798 hours of 2025 at or below zero, and the negative hours got deeper[4]. California curtailed on pace with its record, yet the share of solar curtailed actually fell, from 13 to 11.5 percent, because batteries began soaking up the midday surplus[3]: the first hard evidence that storage, not less solar, is the fix. And where grids and tariffs fail entirely, the buildout simply goes around them: Pakistan imported about 17 GW of panels in 2024, the world's third-largest importer, mostly unpermitted rooftop capacity fleeing grid prices[5].

inferred The dots on this map are utility-scale projects, and their economics now hinge less on the resource than on what surrounds them: storage co-location, transmission, and tariff design. Where those lag, the price of the midday hour, not the cost of the panel, decides the project.
