Solar Power

Swedish thin film solar specialist Midsummer announced the order of a SEK 143.5 million ($14.8 million) turnkey line with a capacity for 15 MW from an undisclosed Swedish industrial and defense group.

pv magazine is compiling a guide to home solar installations, aimed at those who are interested in installing but are new to the market and want to make an informed decision. We have spoken to associations, installers and industry specialists in major solar markets across the globe to compile best practice guidance and advice that aims to be applicable to home solar installations anywhere in the world.

The Aachen-based company has further developed its energy management system (EMS) under real-world conditions, to minimize the cyclic aging of its batteries.

The UK-based company said its new hybrid solution includes a stand-alone monobloc air-to-water heat pump with a nominal capacity of up to 16 kW and one of its boiler range. The heat pump system uses R32 (difluoromethane) as a refrigerant and has a coefficient of performance of up to 5.1.

Chinese battery giant CATL surged 12.55% on its Hong Kong trading debut after raising HKD 35.6 billion ($4.6 billion), marking the world’s largest listing in 2025. The offering drew strong demand from strategic and cornerstone investors, boosting CATL’s market capitalization to HKD 1.34 trillion.

Tunnel oxide passivated contact (TOPCon) modules continued to dominate the PV market at The smarter E Europe 2025, but pv magazine Magazine Director Mark Hutchins and CRU Group Senior Research Analyst Molly Morgan found emerging cell and module concepts gaining ground on the show floor.

pv magazine editor Matthew Lynas toured the startup corner at Intersolar Europe 2025, highlighting emerging businesses focused on flexibility, smart meters, software, and PV integrated with glass.

Germany’s Singulus Technologies will provide three of its physical vapor deposition (PVD) vacuum sputtering systems to Poland-based module manufacturer Roltec at a new plant that will produce copper, indium, gallium, and selenium (CIGS) cells on glass substrates.

Researchers from the Middle East have simulated a novel PV thermal module which includes a thermoelectric generator above the absorber layer, conical helical tape in the cooling tube and a ferrofluid. These technologies reportedly contributed to increased PV efficiency and thermal efficiency by 2.12% and 23.34%, respectively.

New research from the Netherlands has shown that product-service-system business models applied to the PV business encourage the use of high-quality PV products and maximizing system lifespan. Their alleged connection with circular economy principles, however, was found to be weak, with financial considerations being prioritized by customers.
