VoltStorage advances its iron-salt battery technology
German flow battery firm VoltStorage says its next stage of technology development will deliver 20-fold increase in performance.
How long do residential solar inverters last?
Multiple factors affect the productive lifespan of a residential solar inverter. In Part 2 of our series, we look at solar inverters.
New model to identify optimal power sizing ratio for solar inverters
Researchers in Malaysia have proposed a new approach to identify the optimal power sizing ratio to balance PV energy capture with inverter costs. The calibrated model is said to accurately reflect the relationship between inverter efficiency and real-world system behavior.
Diego Luxembourg launches resindential air-to-water heat pump
The Luxembourg-based manufacturer said the new product can reach flow temperatures of up to 72 C and achieve a seasonal coefficient of performance (SCOP) of up to 5.7.
Two-terminal perovskite-CIGS tandem solar cells have technical potential to achieve 26.69% efficiency
A Dutch and U.S. research team performed optical and electrical simulations to understand loss mechanisms in two terminal (2T) tandem cells based on perovskite and commercially available copper-indium-gallium-selenide (CIGS) cells, and subsequently established a roadmap to increase efficiency via four key modifications.
China’s solar dominance not an issue
In a new monthly column for pv magazine, the International Solar Energy Society (ISES) explains why potential trade disruptions in the global PV supply chain are substantially different from those related to coal, oil and gas.
New soiling detection method based on drones, AI, image processing
Developed by scientists in China, the proposed approach uses mathematical morphologies for image processing, such as image enhancement, sharpening, filtering, and closing operations. It also uses image histogram equalization and edge detection, among other methods, to find the soiled spot.
How long do residential solar panels last?
Multiple factors affect the productive lifespan of a residential solar panel. In the first part of this series, we look at the solar panels themselves.
Trina Solar probing potential breaches of TOPCon patents
Trina Solar says it has started evaluating potential violations of some of its patents for tunnel oxide passivated contact (TOPCon) tech. One of the patents focuses on the number of busbars and their width in TOPCon solar panels.
Mecosun offers concrete solar carport
Mecosun says it has introduced a new solar carport in three formats, using low-carbon concrete and an embedded module mounting solution.
