EGbatt releases 15 kWh storage solution for residential use
The Chinese firm has unveiled its latest energy storage solution, the ENERpro-LFP48300, equipped with a 48V, 300 Ah lithium battery. The company boasts a lifespan of over 9,500 cycles at a high 95% depth of discharge.
Scientists achieve 32.6% efficiency in perovskite-silicon tandem solar cell via interface engineering
Researchers from KAUST, TU Delft, and LMU Munich have improved the performance of monolithic perovskite-silicon tandem solar cells by modifying the physical structure at the front of the bottom heterojunction solar cell.
Hungary adds 1.1 GW of solar in 2025
Hungary deployed over 1 GW of solar for the third consecutive year in 2025, driven largely by grid-scale solar additions. There are concerns momentum could slow in the coming years due to no new connection permits for large-scale projects authorized over the last three years.
Japan’s solar industry targets vertical bifacial PV with new guide
The Japan Photovoltaic Energy Association (JPEA) has released a voluntary reference guide to support adoption of vertical bifacial PV in Japan, outlining design, performance, and compliance considerations for projects in snow-prone, high-latitude, and space-constrained conditions.
Ideal Energy commissions AI-enabled flexible HJT pilot line for space
China-based PV equipment supplier Ideal Energy (Shanghai) Sunflower Semiconductor has completed an AI-enabled pilot line for ultra-thin, flexible heterojunction (HJT) solar cells, targeting lightweight power systems for space and near-space applications.
New design specifications for sodium-ion batteries
U.S. scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium-ion batteries, identifying dual ionic and metallic storage mechanisms within the pores. Their findings provide practical design guidelines to improve battery voltage, safety, and commercial viability for stationary energy storage.
China completes first full-scale underwater pumped storage trial at 65 m depth
DEC’s “Dongchu No. 1” prototype completed more than 100 charge-discharge cycles at 65 meters depth in a freshwater lake.
More PV manufacturers expected to adopt copper metallization in 2026
Rising silver prices are pushing PV manufacturers toward copper-based metallization, with DK Electronic Materials targeting 2026 for large-scale deployment of high-copper paste solutions, while Fraunhofer ISE warns efficiency trade-offs remain unacceptable.
Guyana plans three utility-scale solar parks
The three new utility-scale projects in region ten of Guyana, with a combined capacity of 15 MW, form part of wider plans to deploy 33 MW of large-scale solar with accompanying energy storage across four of the country’s regions.
The impact of sand erosion on mounting structures in large-scale PV plants
Researchers in Spain have tested the erosion resistance of common galvanized coatings using both free-falling sand and forced-air sand-impingement methods. The study found that continuously galvanized steel coatings showed the lowest erosion rates, outperforming HDG and Zn-Al-Mg coatings.
