Forecasting growth
India’s expanding utility-scale solar fleet is creating a growing need for accurate generation forecasts. Yet the country does not have one uniform specification for every project. The requirements depend on the connection point, the responsible scheduling entity, and the rules issued by central or state regulators. For forecasting providers, this makes India a sizable market, but one that requires detailed project-by-project implementation, as Reuniwatt’s Hannah Bergler explains.

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.

Targeted recycling of glass-glass modules trades value for lower impact
Targeted recycling of frameless, polyolefin elastomer-encapsulated glass-glass modules lowers energy use and global warming impact compared with treating the whole module, but reduces recovered material value, according to a new study, with silver dominating revenue.
