Dutch trade body Holland Solar is urging the new Dutch government to introduce self-consumption incentives for batteries, boiler tanks, and heat pumps used in combination with PV systems, as the country plans to phase out net metering by 2027.

Tokyo-based startup Girasol Energy and the enterprise bureau of Japan’s Yamanashi prefecture have repowered Japan’s oldest PV system, a 100 kW array built in 1993. The project aimed to partially replace the original 13.3% efficient solar modules, offering an alternative to dismantling and recycling the system’s components.

Researchers in Sweden have measured barney yield in a vertical agrivoltaic facility and have found that despite the shade created by the modules the yields are comparable to open-field control conditions, if not slightly higher. Their methodology can be replicated for other sites and crops.

The Singapore-based manufacturer said its new panel can achieve self-cleaning through rainwater thanks to its frameless design. The new product features an operating temperature coefficient of -0.30% per C and an efficiency ranging from 21.51% to 22.53%.

The two Italian companies said their new modules use a fully recyclable sticker that can help to improve aesthetics and turn the panels into advertising billboards. The panels use 24%-efficient interdigitated back-contact solar cells from Maxeon.

Scientists in China have investigated the fracture strength of commercial G12 monocrystalline wafers via the 4-point bending test and have found that wafer thickness, the position of the silicon wafer in the silicon brick, and the bending test direction are key parameters to develop future strategies aimed at reducing fractures.

Scientists have utilized a device based on the Duffing oscillator to solve the problem of PV systems’ low efficiency at low input voltages at dawn and sunset. Its performance was reportedly better than that of a conventional DC-DC boost converter in amplifying weak input voltages.

Researchers in Denmark have found that using a large-scale air-to-water heat pump in solar district heating may significantly reduce its levelized cost of heat. The proposed system configuration was simulated for an existing district heating plant in Denmark and was found to improve the flexibility of the system in response to energy prices.

JA Solar has filed two patent lawsuits against Astronergy in the Unified Patent Court (UPC). The proceedings are related to the tunneling silicon oxide (SiO2) layers, the doped polysilicon layer, and the electrodes used in tunnel oxide passivated contact (TOPCon) solar products.

The experimental device achieved an open-circuit voltage of 1.21 V, which is the highest value reported to date for highly efficient perovskite photovoltaics. The cell is based on a photo-ferroelectric 2D/3D/2D perovskite junction integrating a 2D ferroelectric perovskite single crystals in the perovskite bulk.
