Spacebound silicon
Solar has a long history in powering satellites and space exploration, and high-powered devices based on multijunction PV cells made from “III-V” materials such as gallium arsenide or indium gallium phosphide have supplied this niche market as far back as the 1960s. But those devices are made with rare materials and complex processing, limited to small batches produced at high cost.

The race for space solar
The space economy could be worth as much at $2 trillion by 2040 – according to a recent report by professional services provider PwC. The cisLunar orbit, between the earth and the moon, is particularly promising. But all of it requires power and, as it has for decades, that means PV – and both the technology and supplier landscape for orbital solar is diversifying. Eternal Sun | WAVELABS‘ Pepijn Veling reports from a series of events the company has attended across the country, on what is a fast-evolving technology and business landscape.

Sunny north and cloudy south as Super El Niño defines South American winter
In a new weekly update for pv magazine, Solcast, a DNV company, reports that Super El Niño drove a sharp north–south irradiance divide across South America in winter 2026, with sunnier conditions in the north and persistent cloud reducing solar irradiance across much of the south. Two rare August snowstorms in Chile’s Atacama Desert also caused likely snow-related losses for solar PV assets, alongside severe rainfall, flooding, and mudslides.
