Retrofits on the rise Down Under
Australia’s push to accelerate electrification while meeting an 82% renewable energy target and retiring coal-fired power plants, both by 2030, is driving the retrofitting of co-located battery energy storage systems (BESS) at existing grid-scale solar farms. Ev Foley of pv magazine Australia reports.

Acid-free molten salt method recovers 94% of silver from solar cells
Researchers in China have recovered 94.34% of the silver from crystalline silicon solar cells using an acid-free molten salt process that detaches the silver as metal, and have identified how to control silicon loss during treatment.

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.

Floating renewables to power data centers
Mocean Energy wants to begin commercial deployments of offshore data centers from 2030. Cameron McNatt, CEO of the Scotland-based startup, explains that its system is modular. Each unit is connected via low-Earth orbit satellite communications and generates between 500 kW and 1 MW without a grid connection. The floating data centers will be combined with Mocean’s existing offshore power system, which includes floating solar and batteries and has completed 18 months of full-scale offshore testing.

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.

New flywheel design could eliminate power converter for grid connection
A research team has built a fixed-speed flywheel prototype that uses a wire-rope mechanism to move weights inward and outward during discharge and charge. The system briefly supplied power to the electrical supply, but steady-state losses prevented net electrical energy discharge over the complete operation.
