Multiple factors affect the productive lifespan of a residential solar inverter. In Part 2 of our series, we look at 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.

The third edition of the Sinovoltaics financial stability report ranking lists India-based Abhishek Corp, Insolartion Energy, Waaree Renewable Technologies, and Solex Energy, all based in India, followed by U.S.-based First Solar as the top five. Six additional manufacturers entered the global ranking.

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.

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.

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.

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.

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.

China’s National Energy Administration (NEA) says the country installed 102.48 GW of new solar capacity in the first half of 2024, bringing its total installed solar capacity to approximately 710 GW.

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.
