U.S. government sets preliminary anti-dumping duties on solar imports from India, Indonesia, and Laos
The U.S. Department of Commerce has issued preliminary anti-dumping determinations for three key solar-exporting nations, establishing duties of up to 123% on crystalline silicon photovoltaic cells and modules.
China wafer declines narrow as demand-side regulation lifts market sentiment
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.
Tesla launches three-phase Powerwall 3P
The system integrates a battery, hybrid inverter, and home energy management system into a single device. It supports the integration of additional appliances, including heat pumps via SG-Ready interfaces. A connection to Tesla’s proprietary wallbox is also planned.
Trina Solar, JA Solar, JinkoSolar launch China’s first PV patent pool for TOPCon technologies
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.
No evidence of PFAS leaching from solar panels, study finds
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 targets C&I with new all-in-one battery
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.
Rethinking silver paste design for TOPCon, LECO solar cells
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.
TBEA launches 500 kW string inverter
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.
Net zero vs net extraction: Are we just shifting the environmental burden?
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.
A closer look at CATL’s new sodium-ion battery
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.
