Solar panels reduce thermal stress in dairy barns during critical afternoon hours
A study from China shows rooftop PV systems on dairy barns can significantly reduce roof heat flux and improve indoor thermal conditions. Field measurements and simulations found up to a 2.3 C reduction in indoor temperature during peak afternoon heat stress periods.
Arctech debuts TOPCon photovoltaic pavement solution
Harmony-F solar flooring can withstand uniformly distributed loads of at least 2 tons and has a hardness above 7 on the Mohs scale, indicating high resistance to wear and abrasion.
Solex Energy plans 5 GW solar cell factory in India
The Indian manufacturer is investing around $420 million to expand its manufacturing footprint alongside efforts to advance high-efficiency PV technologies through its partnership with ISC Konstanz.
Trina launches rooftop solar module with lower-voltage design
The Chinese manufacturer has launched an “Australia specific” variant of its Vertex S+ modules featuring a power output of 515 W and a maximum efficiency of 24.65%. Its lower-voltage design reportedly enables more flexible string sizing, allowing installers to optimize system layouts across a range of inverter configurations.
EU solar and storage push could cut power system costs by nearly half
A scenario analysis by SolarPower Europe, modeled by Rystad Energy, finds that accelerating PV and battery storage deployment could save the European Union €223 billion ($260.7 billion) in gas imports between 2026 and 2030 and reduce wholesale electricity prices by 14% compared with 2025 levels.
New technique measures water ingress in PV modules without disconnecting them
A German research team has developed a nondestructive, on-site method to quantify water ingress in photovoltaic modules using near-infrared absorption (NIRA) spectroscopy calibrated with Karl–Fischer titration (KFT). The approach enables precise measurement of absolute moisture content in sealed modules without disassembly, improving inspection, failure analysis, and lifetime prediction.
Fluorine use in PV backsheets dropped sharply over past three decades
Researchers in Austria found that fluorine and fluoropolymer content in PV backsheets has significantly decreased over the past three decades, driven by a shift from fluorine-rich multilayer structures to fluorine-free or coated alternatives. Despite this decline, fluoropolymer-containing backsheets remain important for end-of-life management due to environmental persistence concerns.
Japan reopens NEDO perovskite solar call with single-junction focus
Japan’s New Energy and Industrial Technology Development Organization (NEDO) has opened a supplementary call for proposals on mass production of next-generation single-junction perovskite solar cells, with submissions due by June 3.
Study finds ‘relatively good’ agreement in worldwide solar cell calibrations, but flags key differences in testing methods
An interlaboratory comparison across nine metrology institutes found generally good agreement in solar cell calibration under the World Photovoltaic Scale, but still revealed measurable differences in short-circuit current, voltage, and power due to varying methods and conditions.
Chinese PV Industry Brief: Longi, Trina Solar report losses
Longi says its 2025 revenue and losses declined year on year, while Trina Solar reports deeper full-year losses and margin pressure across its core module business.
