New research shows the importance of calculating the effects of shading created by PV panels on the photosynthetically active radiation (PAR) at the ground level, which is crucial to assessing crop yield in agrivoltaic projects. The proposed modeling considers different agrivoltaic project typologies across several sites in Europe.
New research from Germany shows that most of the heat pumps deployed in existing multifamily buildings may have to operate close to their water temperature operating limit (WTOL), thus being unable to provide elevated temperatures above 60 C. The researchers warned, however, that proper installation proceedings and new types of heat pumps may help solve this issue.
New research from Finland shows that the best season for rooftop PV generation in the Arctic is spring, and that the best tilt angle for rooftop systems is 28 degrees. It also showed that vertical PV installations perform better in winter.
Italian researchers have compared the performance of hydrogen and electric buses in northern Italy, while DNV has released its guidelines to validate claims related to low-carbon renewable hydrogen and ammonia attributes.
Energy Storage Industries is delivering 1 MW/10 MWh of flow battery storage to the Stanwell Power Station in the Australian state of Queensland. The flow batteries are part of a new government-run clean energy testing “hub,” featuring hydrogen and additional workforce training programs.
Dryad Networks has developed an AI-powered sensor to detect wildfires and notify first responders.
Ongoing innovation in PV cell technology will have major impacts as solar is deployed at a “multi-terawatt scale” over the next two decades, according to a global team of scientists.
An international research group has applied for the first time integral backstepping control (IBC) as a control strategy for PV systems connected to microgrids. Through a series of simulations, the scientists found the new approach can provide better results than classic backstepping control (BC) and other techniques.
Scientists in Pakistan developed a new cleaning system that reportedly not only reduces power losses caused by soiling but is also able to increase PV module performance by reducing its temperature. It could be applied to both residential and commercial PV systems.
Lochinvar has developed a heat pump with a hot water supply of up to 70 C, with a coefficient of performance (COP) of 5.5. The system is entirely cascadable, offering outputs ranging from 88 kW to 880 kW. It also includes 455 liters of hot water storage capacity and uses propane (R290) as a refrigerant.
