Wuxi DK Electronic Materials is pursuing two patent infringement cases against domestic competitors, seeking injunctions, equipment destruction, and combined damages of CNY 400 million ($57.5 million).

The Finnish start-up says its sand battery technology is scalable from 20 to 500 MWh with charging power from 1 to 20 MW, depending on industrial needs.

Scientists have grown organic romaine lettuce under 13 different types of PV modules, in an unusual hot Canadian summer. Their analysis showed lettuce yields increased by over 400% compared to unshaded control plants.

Polysilicon trading in China remained largely inactive, with production cuts accelerating and wafer prices falling week on week, while downstream cell prices continued to rise and module prices held steady, according to a trade group representing China’s nonferrous metals sector.

Cubenergy has launched FlexCombo 2.0, a scalable battery energy storage system for utility, commercial, and industrial applications, offering up to 16 MWh capacity with LFP batteries. Its modular design, advanced BMS, and cloud-based operations enable easy installation, seamless expansion, and efficient grid integration, according to the manufacturer.

This week Women in Solar+ Europe gives voice to Alba Sande, lawyer at Spanish law firm ASande Legal. She states that, despite progress, women remain underrepresented in the renewable energy industry. “As a woman and a mother, I have often encountered the unspoken assumption that professional ambition must take a backseat to family life, a bias rarely applied to men,” she says.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that in January most of East Asia experienced normal to above-average solar irradiance, with southeastern China seeing surges due to reduced clouds and low aerosol levels under lingering La Niña effects. In contrast, the Philippines faced below-average irradiance from early Tropical Storm Nokaen, while other regional cities like Seoul, Tokyo, and Taipei recorded modest gains.

Researchers at SUPSI found that six Swiss PV systems installed in the late 1980s and early 1990s show exceptionally low degradation rates of just 0.16% to 0.24% per year after more than 30 years of operation. The study shows that thermal stress, ventilation, and material design play a greater role in long-term module reliability than altitude or irradiance alone.

Sweden deployed less solar in 2025 than the year prior despite record growth in the large-scale segment. Solar association Svensk Solenergi predicts last year was likely the bottom of Sweden’s installation curve.

Pacifico Energy Chief Operating Officer Kevin Pratt says projects such as the planned 7 GW GW Ranch microgrid in Texas highlight a shift toward private grids as developers seek faster, more reliable ways to meet surging power demand from data centers and industry.
