China’s solar industry has launched its first TOPCon-focused patent pool, led by Trina Solar, JA Solar, and JinkoSolar, to streamline licensing, reduce disputes, and strengthen IP coordination at home and abroad.

Researchers in the United States reviewed claims about PFAS in solar panels and found that while fluoropolymers may be used in limited components like backsheets or coatings, there is no confirmed evidence of PFAS leaching from commercially deployed modules. The study highlights widespread confusion between different PFAS types and emphasizes the need for clearer communication and transparency around fluoropolymer use in PV technologies.

SolarEdge has a new commercial focused battery system, with the new model scaling up to as high as 1 MW / 4 MWh depending on the inverter choice.

Researchers in China have developed an evaluation framework to better assess fine-line silver pastes for TOPCon and LECO solar cells. The approach links laboratory characterization directly with production-line performance, addressing the limitations of conventional evaluation methods.

The new inverter is designed around standardised 5 MW and 5.5 MW PV sub-arrays with the aim to reduce balance-of-system costs. It features a maximum efficiency of 99.0% and a high-voltage architecture of up to 1,600 Vdc and 1,000 Vac.

Burden shifting refers to reducing environmental impact of one category causing increase in another; or reducing harm in one geography while concentrating it in another. On both dimensions, the evidence of burden shifting of the lithium-ion supply chain is evident and should not be ignored.

The battery manufacturing heavyweight presented its latest sodium-ion products at ESIE 2026 earlier this month, expanding its push into grid-scale storage, AI data centers, and long-life applications.

Latest report from the International Energy Agency says last year’s 600 TWh increase in solar PV was the largest-ever electricity generation increase by any source in one year, outside of periods of post-crisis recovery.

The U.S. Patent and Trademark Office has invalidated all claims of two TOPCon solar cell patents previously asserted by Trina Solar against Canadian Solar subsidiaries.

A research team in Germany developed a dynamic model of spray cooling for floating PV systems that couples thermal behavior, electrical performance, and active cooling, and validated it against a 750 kW installation. Simulations across four climates showed that spray cooling reduces module temperatures by up to 42% and improves energy yield by up to 3.8%, with benefits strongly dependent on local conditions.
