EVE showcases 6.9 MWh storage system, targets Q3 scale-up
China’s EVE Energy recently presented a 6.9 MWh battery energy storage system integrating its 628 Ah cells and announced its 2025 half-year results.
Novel MPPT technique for EV charging combined with PV, fuel cells
Scientists in India have designed a system that uses PV panels, a proton-exchange membrane fuel cell, battery storage, and a supercapacitor. It also relies on an adaptive neuro-fuzzy inference system-based MPPT that reportedly achieves an efficiency of 98.7%.
SolaX presents balcony storage system
Chinese manufacturer SolaX Power has unveiled its Balcony X-MS 2000, a lithium-phosphate battery storage system for residential microgeneration supporting up to 2,400 W of solar input.
Micoe showcases residential PV water heaters
The Chinese company said its new PV-driven water heaters are combinable with grid electricity to ensure continuous domestic hot water supply. The new products rely on MPPT controllers and a digital control panel featuring programmable temperature settings and timer functions.
SAJ launches HS3 6-in-one home battery with 40 kWh storage
China’s SAJ has launched its HS3 6-in-one home battery series, available in single- and three-phase configurations with 1,000 W to 15,000 W of PV input and up to 40 kWh of lithium iron phosphate (LiFePO4) storage.
Sunwoda debuts 684 Ah storage cell, targets mass production in early 2026
Mass production is planned to begin in the first quarter of 2026, targeting an initial annual capacity of 10 GWh.
Reducing PV module temperature with ultra-cooling patch
Scientists in Hong Kong have developed a patch that effectively cools down PV panels and utilizes waste heat for freshwater production. It has three layers: an atmospheric water harvester, a thermal regulation layer, and an adhesive layer. Maximum power density reportedly increased by over 28% in a folded version of the ultra-cooling patch.
Bridgestone World Solar Challenge leaderboard: what’s on deck
This edition of the 3,000 km solar car race across Australia from Darwin to Adelaide has the same teams in the lead in the Challenger class since early on. Each has a 6 m2 solar deck but no two are exactly the same.
Germany records 453 hours of year-to-date negative electricity prices
Germany has logged 453 hours of negative day-ahead power prices this year, already above the total in 2024, while hours above €100 ($116.,54)/MWh have also surpassed last year.
Argentina’s oversubscribed BESS tender draws record-low bids
The Argentine Energy Secretariat has received significantly more bids than expected for its public call to install large-scale battery energy storage systems (BESS) in the Buenos Aires metropolitan area (AMBA). Although the tender aimed for 500 MW, the AlmaGBA procurement drew proposals totaling 1,347 MW on the back of highly competitive pricing and strong industry interest.
