Maldives kicks off tender for 15 MWp of grid-tied solar systems
The Maldives is accepting bids from developers to install 15 MWp of solar systems across selected islands under a design, build, finance, own, operate, and transfer basis. The deadline for applications is Oct. 22.
Australian electricity market operator expects 86 GW of rooftop PV by 2050
An industry data exchange co-design is putting consumer energy resources at the beating heart of Australia’s energy marketplace, prompted by a 2050 projection of 86 GW of rootfop solar and 27 GW of flexible demand in the National Electricity Market (NEM).
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.
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.
India imposes 10% customs duty on solar glass imports
The Indian authorities will introduce a 10% customs duty on solar glass imports from October. The government has also expanded the list of exempted equipment for solar cell and panel production to support domestic manufacturing.
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.
Puerto Rico in line for 1.14 GWh of battery storage
A new U.S. Department of Energy loan guarantee will help finance 200 MW of solar and 285 MW of grid-scale storage on the island.
The Hydrogen Stream: New way to make hydrogen, fertilizer from ammonia
German researchers have developed a new way to liberate hydrogen from ammonia, while a new MIT study shows the need for stringent emissions regulations on ammonia combustion for maritime mobility.
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.
