Session: 5CV.2 Operation, Performance and Maintenance of PV Systems
Topic: 5. 3 Operation, Performance and Maintenance of PV Systems
Summary / Abstract: Soiling is the process whereby dirt, dust and organic/inorganic contaminants deposit on the surface of a PV module causing a decrease on the energy generation. It impacts PV systems worldwide causing energy and economic losses and also affects the expansion of PV generation. However, compared to other PV performance issues, soiling is reversible and can be mitigated. The first step to address appropriately soiling is monitoring, since the mitigation strategy must be planned according to the site-specific characteristics of the system and of the location. Following the recommendation of the standards for monitoring PV systems it is possible to analyze and estimate the market size of soiling sensors as well to recommend the maximum costs to target. The estimation shows that 67,000 sensors were already necessary just to cover the PV capacity worldwide installed up to 2019 and that around 25,000 sensors will be necessary to cover the capacity added by 2024.
