It was found that the optical pollution loss of CSP was 8–14 times higher than that of the PV module under the same dust accumulation density. Wu et al. [19] determined that the dust accumulated on the solar trough concentrator reduced the reflectivity by absorbing and scattering sunlight. When the reflectivity was less than 90%, the concentrator needed to be cleaned. …
