What Is The Greatest Environmental Hazard For Solar Energy? Dust!
With such a groundswell of solar growth, what can limit the performance of PV systems? The answer is dust, or other forms of soiling that accumulate on the glass surface of solar panels, obscuring light from the cells within. Driven by location and weather, soiling is worst in deserts like the US Southwest, in the presence of air pollution, and on solar arrays that have flat tilt designs
