What 11 islands reveal about the real bottleneck in renewable mini-grids
An IEA-PVPS report examining 11 islands finds that achieving nearly 100% renewable electricity depends as much on strong leadership, community engagement, financing and early planning as on technology. While proven technical solutions vary widely, successful transitions require tailored grid design and sustained institutional support, making replication especially challenging for smaller, remote and lower-income islands.

Racking it up to experience
Demand for solar rooftop racking systems in Europe has either slowed or changed over the past year, depending on who you ask. Either way, the mood is cautious among European mounting and racking system providers, likely due to a downturn in the commercial and industrial (C&I) rooftop solar market, as businesses have less cash available for solar installations.

Distributed outlook
India’s installed solar capacity has grown from less than 5 GW in 2016 to more than 165 GW today. While ground-mounted mega projects have led with a contribution of over 120 GW, rooftop solar is rapidly catching up, contributing more than 30 GW as of August 2026. Instead of adding capacity, the next decade will focus on where this capacity is located, how it interacts with the grid, and the flexibility it can provide. Shantanu Roy of CSTEP, a research-based think tank in India, expects this to open more doors for distributed solar.

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.
