Preventing soiling with surface textured photovoltaic dummies

Scientists in South Africa have used computational fluid dynamics to investigate whether a dummy panel, placed in front of a working PV panel, can mitigate soiling. They have tested this setup with various inclination angles, heights, and distances and have found that the dummies accumulated up to 58% more dust than the PV panels. Researchers from the University of South Africa have proposed a novel soiling mitigation approach for PV panels by placing non-working textured PV dummies in front of active PV modules. They used computational fluid dynamics (CFD), which is a technique used to predict ...
