FAQ

• Cleaning

  • What is the periodic time to clean the DustIQ?

    • The DustIQ is never cleaned on its own. It is only cleaned when the actual PV modules are cleaned. Then it remains "in sync" with the real PV modules.

  • How should the DustIQ itself be cleaned?

    • The DustIQ is made of PV module material like the glass and aluminium. Thus, the same procedures as for cleaning the PV modules can be used.

  • What data filtering/filters should be applied to raw data measured by the DustIQ to make the measurements useful for soiling analysis and wash decision?

    • Remove all data when the weather station indicates rain (30 minutes before and 1 hr after) and when the dew point is close to or below the PV module temperature (dew). Or install a Modbus dew-rain sensor next to the DustIQ.
      
      

  • We are using self-powered module cleaning robots. If we keep its frequency of say twice a week, will dust measurement sensors be required?

    • Probably not, but the PV plant owner might ask you to show that indeed the PV modules were cleaned (step change in soiling loss) and how good the robots do their job (how close to 0% loss you get)
