What happens when malware hits PV systems
A random malware variant affected about 800 remote monitoring devices at ground-mounted PV plants in Japan in May 2024. Tokyo-based cybersecurity firm Girasol Energy has told pv magazine what happened and how PV asset owners can protect themselves against such incidents.
Controlling grid fluctuations via solar module cooling
A research group has proposed a novel method to control ramp rates in power networks. Its control optimization is based on weather, load and production forecast data. The scientists simulated the operation of the proposed technique and reached a ramp rate reduction of up to 76.2%.
Metrel launches electrical installation safety tester for PV systems
Metrel, a Slovenian measurement equipment supplier, says its new electrical installation safety tester can assess systems with a maximum voltage of up to 1,500 V and a maximum short circuit current of 40 A.
Greek researchers develop privacy-preserving PV forecasting technique
Researchers from Greece have developed a PV forecasting technique for prosumer schemes using federated learning, a machine learning method that sends local model updates to a central server for correction. Their simulations show surprising results compared to centralized forecasting.
Ultra-short-term PV power forecast based on dung beetle algorithm
Researchers have developed a novel deep-learning method to predict ultra-short-term PV power, using an optimization method that is based on the behavior of dung beetles. The proposed approach reportedly performed better than seven other conventional prediction methods over a 1-year period.
New sun simulator, light-soaking tools for perovskite solar cells, modules
MBJ Solutions, a German testing equipment specialist, recently launched two new products for developers of perovskite and perovskite silicon tandem devices. The MBJ Steady State Sun Simulator is designed for cells and small perovskite module research, and the MBJ Light Soaking Unit is for aging tests and preconditioning.
Mobile PV-powered EV charging stations for commercial, industrial sites
United Kingdom-based 3ti Energy Hubs has launched a portable electric vehicle charging station for 12 cars that it delivers to commercial and industrial sites where demand exceeds supply.
Powering restaurants with rooftop PV, reversible fuel cells
Researchers have simulated the operation of bifacial PV and proton exchange membrane reversible fuel cells across restaurants in five different US states. Taking into account varying rates of bifacial PV’s rearside gains, they found that LCOE was as low as $0.029 per kWh.
Shoots of growth for Indian green hydrogen
India is laying the foundations of a hydrogen economy with huge governmental support. pv magazine spoke to Jakson Green CEO Bikesh Ogra about the company’s manufacturing and production activities in light of India’s ambitious hydrogen plans and the central role electrolyzer manufacturing is set to play.
Large-scale PV has positive environmental effect on desert areas
Researchers from China found that big solar power plants have a positive positive impact on the ecological environment of desert areas. Their testing was conducted at a 1 GW solar park located in China’s northeastern Qinghai province.
