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.
The world added 605 GW of new PV capacity in 2025, says IEA
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.
Trina Solar TOPCon patents invalidated in US ruling involving Canadian Solar
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.
Spray cooling for floating PV
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.
JinkoSolar debuts rooftop PV module weighing 7 kg/m2
The Chinese manufacturer said its lightweight Light Diamond TOPCon module delivers 560 W at 24.94% efficiency.
China polysilicon hits cost floor as producers curb output amid weak demand
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.
Welspun New Energy signs 200 MW solar-plus-storage PPA with SECI
Welspun New Energy has signed a power purchase agreement (PPA) with Solar Energy Corp. of India (SECI) for a 200 MW solar project paired with a 400 MWh battery energy storage system (BESS).
New metric shows renewables are 53% cheaper than nuclear power
A new metric for assessing total system costs puts a least-cost mix of offshore wind and solar at about €46 ($54.20)/MWh in a future climate-neutral energy system for Denmark. Researchers tell pv magazine that figure is less than half the equivalent cost of nuclear under the same conditions.
