BNEF flags potential global solar slowdown in 2026 as China cools
BloombergNEF (BNEF) projects a slight year-on-year dip in global solar additions in 2026 as China’s growth eases, even as installations elsewhere continue to rise.
Too much to choose from, too little to decide
Market pressure in the solar and storage sectors often favors low-cost solutions, but long-term success depends on balancing price, quality, and reliability for assets designed to operate for decades. Numerous examples, from low-grade silicon modules to residential hydrogen and redox flow storage, show how technically ambitious products can fail when costs, complexity, or durability are misjudged.
Researchers find sodium-ion batteries using hard carbon anodes can intrinsically charge faster
Researchers at Tokyo University of Science showed that sodium-ion batteries with hard carbon anodes can charge faster than lithium-ion batteries by using a diluted electrode method that reveals sodium insertion is intrinsically quicker than lithium.
China files WTO complaint against Indian solar subsidies
China’s Ministry of Commerce has raised a complaint at the World Trade Organization (WTO) regarding India’s solar subsidies, claiming they give the country’s domestic industry an unfair advantage and harm Chinese interests.
All solar cell efficiencies at a glance – delayed
The research group led by Professor Martin Green has not published yet Version 67 of the solar cell efficiency tables, due to production delays. Green, however, has accepted to comment on some of the results to be added in the upcoming edition.
Europe’s first sodium-ion cell made with fully domestic components
Welsh battery breakthrough uses UK-manufactured anode and cathode materials as well as active materials available through local supply chains. Batri plans to scale up material manufacturing and cell building capability.
Revival of Nature-based Solutions (NbS) in 2025
The IUCN’s updated Global Standard, growing debate on finance, and stronger emphasis on rights and monitoring mark a transition from hopeful experimentation to disciplined scaling. If the next year invests in credibility and the scaffolding that turns pilots into pipelines, Nature-based Solutions could finally become a practical pillar of climate, biodiversity and development strategies worldwide.
China TOPCon cell prices dip despite looming cost pressures
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
European solar manufacturers urge Italy to revise heterojunction tax rule
Eleven European solar module makers say Italy’s 2026 tax incentive unfairly favors heterojunction (HJT) technology, risks higher costs and limits competition across the PV market.
French testing body flags durability risks in TOPCon solar modules
Accelerated testing by French certification body Certisolis finds wide performance divergence and design vulnerabilities in tunnel oxide passivated contact (TOPCon) solar modules that current international standards do not capture.
