  "abstract": "Dirt on the mirrors of a concentrated solar collector reduces the absorbed thermal power and, thus, the amount of heat produced. This implies periodic cleaning and additional water consumption to ensure a good performance. Most existing cleaning strategies involve manually cleaning mirrors with pressurized water or using cleaning vehicles, which entail additional maintenance costs and reduce the system's profitability. In this work, a simple cleaning strategy, consisting of cleaning the mirrors with rainwater, is proposed and tested in a facility with a Linear Fresnel solar field. For this purpose, a rain sensor was installed. When it rains within a specific threshold, the mirrors are tilted so rainwater naturally cleans the dirt. To quantify the effect of this cleaning strategy, the evolution of the mirror's reflectance was measured with a portable reflectometer in two campaigns: one with no cleaning and one with the rainwater cleaning strategy. In addition, the evolution of the mirror’s reflectance has been correlated, including a term that decreases reflectance with operating hours and another that increases reflectance when the mirrors are cleaned with rainwater.",
