A group of 35 French agricultural entrepreneurs decided to change their agricultural practices to adapt to the low quality of their groundwater and chose agrivoltaics as a way to compensate for crop yield losses.

Hyperion Renewables launched an EPC tender for its Green H2 Setúbal Project back in March. Seven companies are now competing to build a plant with a green hydrogen production capacity of 135 kg (1,500 Nm3) per hour. The plant will be fed by 12 MW of solar PV.

Norwegian startup Sunlit Sea has designed a floating array consisting of a single unit float built-in cold-pressed aluminum with a close-to-standard solar panel bonded on the top surface. A 22.7%-efficienct mono PERC photovoltaic panel is bonded to the top of the float, giving a total unit thickness of 85 mm.

Researchers in the Netherlands investigated the potential for integrating power electronics in solar cells in the form of diodes, transistors, capacitors, and inductors. They believe that this kind of PV cell may initially find applications in PV-powered Internet-of-Things (IoT) devices and later, as the economy of scale kicks in, in large-scale applications.

France’s Q Energy has developed a new way to combine solar generation and the cultivation of hops, which can grow up to 8 meters in height. The agrivoltaic system consists of two mounting units with 52 bifacial PV modules.

Romania has unveiled a state aid scheme to support investments in the production of hydrogen powered by solar, hydro and wind, while Air Products and Gunvor have agreed to build a hydrogen import terminal in Rotterdam.

Buildings, particularly those with glass facades, are getting closer to self-powering, according to Australian scientists who recently developed a 15.5%-efficient, semi-transparent solar cell that allows more than 20% of visible light to pass through.

Norway’s Glint Solar has developed cloud-based software that finds suitable surfaces for solar parks. It analyzes factors such as the distance to the grid or substations, topography, soil depth, and solar radiation. The tool can also be used for preliminary project sizing.

Spanish heating specialist Elnur Gabarron offers a residential heating system that works with surplus solar power and storage heaters. The system can work as a backup solution, combined with existing conventional heating, or as a household’s main heating system, with minimal use of grid electricity.

A research group led by Chinese manufacturer JinkoSolar has developed a tandem perovskite-silicon cell with a subcell based on TOPCon tech. The group succeeded in reducing voltage losses in the silicon sub-cell by minimizing the shunting probability during device fabrication.
