Soiling Measurement Kit

Soiling Measurement Kit

  • Determine PV performance losses due to soiling
  • Calculation of the Soiling Loss Index (SLI) and Soiling Ratio (SR)
  • Measurement of short circuit current and module surface temperature

Soiling significantly affects the energy production of PV power plants. Effects of soiling on PV modules should be assessed site-specific due to variations in soil type, location and weather patterns. Implementing an Ammonit soiling measurement kit helps you to:

  • Analyse soiling losses in the PV module performance
  • Quantify site-specific impacts of soiling on PV energy production
  • Optimize cleaning routines for best return-on-investment
  • Determine typical soiling rates for forecasting models

Soiling is the accumulation of dust, dirt and other contaminants on the surfaces of PV modules. The amount of dust is extremely dependent on the location of the PV power plant, e.g., desert valley with sand storms. 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.
