Dear Reader,

Soiling significantly affects the energy production of PV power plants. Do you know how much PV module output power is lost due to soiling? In absence of significant rain events or regular cleaning, production losses due to soiling effects increase. Measuring soiling effects provides important details about the PV power plant production, e.g., how much dust can be on the modules before any problem occurs and how does the dust affect transparency and efficiency of the modules.

However, effects of soiling on your PV modules should be assessed site-specific due to variations in soil type, location and weather patterns. We offer soiling measurement systems for PV power plants, which can be used for:

• Analysing soiling losses for PV performance guarantees
• Monitoring soiling losses to enable detection of other system-level issues
• Optimizing washing schedules for best return-on-investment
• Determining typical soiling rates for forecasting models

Our soiling measurement systems compare power output and surface temperature of a naturally-soiled PV reference module with the data of a clean PV reference device. The measurement station determines local solar irradiation for power output parameter evaluations. Additionally, several meteorological parameters are measured to give a detailed insight into the local weather conditions.
