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).

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.

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.

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.

Dutch utility Eneco is testing low-noise air-to-water heat pumps from startup Whspr in around 20 homes, aiming to ease installation constraints near property boundaries. The systems reportedly achieve coefficients of performance of up to 5 and show up to 80% noise reduction in laboratory testing.

The UK-based perovskite solar PV specialist has announced a new metrology research project with Swansea University and a new development agreement with Renolit, a German plastic films, sheets and polymer solutions company.

The new Tesla Solar Panel and mounting system pairs with the company’s inverter, Powerwall battery, EV charging and vehicles, creating an all-Tesla residential solar offering for the first time.
