New deterioration diagnosis tech for individual modules in PV panel strings
Conceived by scientists in Japan, the system consists of a a xenon flash lighting system and a detector capacitor. It can reportedly examine solar modules and find the degraded ones without disconnecting the string’s electrical wiring.

New tool to estimate cities’ rooftop PV potential considers roof superstructures
Called SolarNet+, the novel framework is claimed to calculate cities’ PV potential not only by finding the orientation of roofs in areal imagery but also by identifying superstructures such as windows or chimneys. It was tested using areal photographs from Munich and Brussels and proved superior to reference frameworks.

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.
Israel’s N2OFF enters solar business
Agri-food tech specialist N2OFF says it has entered the PV business by lending €375,000 ($407,000) to Israeli PV developer Solterra Renewable Energy. The loan is part of a larger €500,000 agreement, with the remaining €125,000 to come from other parties.

k-Nearest Neighbors algorithm for PV power forecasting
Scientists in Iraq used a k-Nearest Neighbors algorithm to evaluate the operational status of PV modules under various conditions, including partial shading, open circuit, and short circuit scenarios. They found that the overall performance of the model in predicting power output was “notably accurate.”
