Reducing PV module temperature with water, thermoelectric coolers
Scientists in India have suggested to use thermoelectric cooling to enhance PV module performance. Through a field experiment, they found that thermoelectric coolers combined with water can reduce solar module temperature by up to 38 C.
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.
