Brion Solenergi has started working on the Nordic region’s biggest rooftop solar project. The 14 MW array will span the rooftop of a warehouse owned by Danish transport company DSV.

Nikola plans to sell 100 hydrogen fuel-cell trucks for logistic operations in California, Volvo has started developing hydrogen combustion trucks, and Airbus has announced plans to launch a study into hydrogen projects in the US state of Georgia.

New research from Sweden suggests that low platinum fuel cells for hydrogen vehicles, when scaled up for the same number of cells, may achieve similar or higher efficiencies compared to commercial fuel cells. Their modeling is expected to act as a bridge between material science research and vehicle implementation.

China’s Kaisheng New Energy Technology has agreed to produce a new line of thin-film solar panels for rooftops under an original equipment manufacturer (OEM) agreement with Sweden’s Midsummer. The modules will be exclusive to the European rooftop market through Midsummer.

Researchers in Sweden have investigated incentive programs for rooftop PV and proposed the adaptation of future schemes to different investor profiles.

Swedish thin film solar manufacturer Midsummer has selected a factory in southeastern Sweden to develop its new solar module production facility, which will produce copper indium gallium selenide (CIGS) solar cells for the European market.

German and Swedish researchers calculated the supply of materials to produce perovskite tandem PV at a multi-terawatt-scale, flagging the difficult supply of gold, indium and cesium, well as a need to streamline production of certain materials used for hole-transport layers. “In essence, we might be able to go post-fossil fuels, but we can’t go post-minerals,” the research’s corresponding author, Lukas Wagner, told pv magazine.

An international research team has used the convolutional neural network (CNN) deep learning algorithm to identify faults in solar panels. Its work showed the proposed technique has a high degree of accuracy, especially if combined with transfer learning models.

Researchers in Sweden have analyzed how roll-bonded PVT collectors can act as secondary heat sources in ground-source heat pumps and have found they provide a better performance than conventional PVT panels. Their techno-economic analysis also showed roll-bonded PVT systems can be up to 9% more expensive than conventional installations based on sheet and tube absorbers.

ABB Motion has unveiled a new solar drive for water pumping, featuring integrated maximum power point tracking (MPPT) logic to maximize operations, with an input voltage ranging from 225 V to 800 V.
