Spanish researchers found that combining agrivoltaics with regulated deficit irrigation can cut tomato irrigation water use by about 50%, while improving land-use efficiency through simultaneous crop and solar energy production.

Researchers have identified a new source of underperformance in utility-scale PV plants caused by “suboptimal backtracking” on slightly uneven terrain. The study shows that real tracker control systems deviate from ideal flat-terrain assumptions, reducing irradiance capture and causing measurable energy losses compared with simulations.

Australian battery storage developer Akaysha Energy makes a sizable move into Germany as it continues to grow its global energy storage system portfolio.

Solar Fabrik has introduced a 400 W red-brown glass-glass PV module designed to meet strict aesthetic requirements for historic and protected buildings, offering a 20.02% efficiency and compatibility with traditional tiled rooftops.

Researchers in the United Kingdom have developed a smart window that combines switchable polymer-dispersed liquid crystal with integrated PV cells, offering controllable transparency and electricity generation. The system balances light, heat, and solar protection while maintaining high visual quality and stable performance, according to its creators.

The K2 MultiRail High mounting system is a one-piece elevated solution with a height of 100 mm tailored to improve rear ventilation on metal roofs. K2 Systems says greater distance between modules and metal roof surface improves airflow and lowers module temperature, which can translate to higher annual energy yield.

An international research team, including scientists from the University of Queensland, boosted triple-junction solar cell performance by enhancing perovskite crystal growth, increasing middle-cell light absorption, and adding reflective nanoparticles.

In an interview with pv magazine, Empa scientist Mirjana Dimitrievska explains that the CIGS photovoltaic technology, while promising for efficiency and flexible applications, faces persistent challenges in scaling lab-level performance to cost-effective, high-throughput industrial production, limiting its ability to compete with crystalline silicon. She also emphasizes that long-term stability, reliability, and material sustainability, rather than peak efficiency, are crucial for commercial viability, especially in niche markets like building-integrated and lightweight PV.

The energy storage efficiency of 12 solar storage systems with capacities of 5 kW or 10 kW has been put to the test, including several new products, all of which achieved efficiency class A. The latest interation of the annual study also examined efficiency losses when storing electricity from the grid and took a closer look at the warranty conditions of the devices.

Let’s say you want to encourage more drivers to shift to battery-electric vehicles. What’s the best way to do it?
