| The effect of soiling in flat PV modules has been already studied, causing a reduction of the electrical output of 4% on average. For CPV¿s, as far as soiling produces light scattering at the optical collector surface, the scattered rays should be definitively lost because they cannot be focused onto the receivers again. While the theoretical study becomes difficult because soiling is variable at different sites, it becomes easier to begin the monitoring of the real field performance of concentrators and then raise the following question: how much does the soiling affect to PV concentrators in comparison with flat panels?¿ The answers will allow to predict the PV concentrator electrical performance and to establish a pattern of cleaning frequency. A first and simple experiment is being conducted at the IES-UPM site, consisting in four linear reflective concentration systems, one point focus refractive concentrator and one flat module. All the systems have been measured when soiled and then after cleaning, achieving different increases of ISC that are 14% on average for the CPV systems when they are soiled in comparison with the 2-4% of the flat panels. | |
