Dual-axis solar tracker based on UV, MEMS sensors Researchers have designed a new tracking system that utilizes an arithmetic optimization-based PID controller. The proposed tracker uses two different sensor types – a UV sensor and a micro-electromechanical solar (MEMS) sensor. The first one calculates the intensity of UV radiation received from the sun, and the second one forecasts the sun’s path across the sky.

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.
