Page 7: Planning The Installation And Use Of The Dustiq
Planning the installation and use of the DustIQ This chapter describes the best locations to place the DustIQs and how to make the best of the acquired data. Where to place DustIQ in the PV plant Measuring dust and soiling ratio is a new field of science. There are many opinions about it, but there is no large history of data and experience in measurements. -
Page 8: How To Value Dust Measurements
How to value dust measurements Measuring dust is a new area with new challenges. Below are a few of them explained. Introduction DustIQ is not an indicator of dust, but a real accurate measurement device, in line with all Kipp & Zonen instruments. The DustIQ measurement technology is unprecedented and new to the market. -
Page 9: The Influence Of Dew And Rain
Hypothetical PV AC output at the 6th of august 2017 in Mongolia and SR over the day. Combining the information from both graphs, we calculated the SR weighted by the PV output for both locations DAILY_AVERAGE and concluded that there is very little difference between Dubai (latitude= 24.4) and Mongolia (latitude = 47.9) The influence of dew and rain The DustIQ measurement are sensitive to dew and rain and measurements done during these conditions must... - Page 10 It’s the trend line over a longer period of time that gives the best overview of the transmission loss. The spikes visible are due to morning and evening dew. The bigger, longer lasting changes are the result of rain cleaning the panel.

Page 13: Dealing With Small Offsets In Transmission Loss Or Soiling Ratio
Dealing with small offsets in transmission Loss or Soiling Ratio When a DustIQ is completely clean the sensors are not measuring zero reflection of the pulsed blue LED light. There is some reflection from the glass. With soiling added there will more reflection and the increase is translated into transmission loss. -
Page 14: Dust Measurements Before Local Calibration
Dust measurements before local calibration The DustIQ is factory calibrated using Arizona Test Dust which is produced in compliance with: ISO 12103-1:2016 A4 coarse test dust. Arizona Test Dust is available with certificates on chemical composition and grain size and is commonly used by the scientific community, but it has proved to poorly represent the soiling observed by DustIQ users e.g. -
