  • Supports compliance with IEC 61724-1 specifications

Portable Soiling Sensor

HS-SMS-012

The Portable Soiling Sensor calculates the soiling ratio on the panels by utilizing the reflection and scattering properties of light based on optical principles. For this calculation, the user must first enter parameters related to the characteristics of the solar panel and dust, such as the panel cell color, the color of the dust on the panel, and the dust tone, into the sensor via the LCD screen. Subsequently, the lamps reflect stable light with a high lumen value onto the panel surface. Reflected light is detected and measured by a high-precision sensor located within the mechanical structure. These irradiance values are read by the microcontroller on the integrated electronic board. The advanced software within the microcontroller analyzes this data and calculates the soiling ratio. The calculated soiling ratio is displayed digitally to the user on the sensor’s integrated LCD screen.

The Automatic Soiling Sensor

HS-SMS009

  • The Soiling station HS-SMS009 is useful device for maintaining solar panel efficiency! By detecting and quantifying the amount of dust accumulation, the Automatic Soiling Sensor helps ensure that solar panels are operating at their peak performance. It’s especially valuable for large-scale commercial and industrial solar installations, where even small losses in efficiency can add up over time.
  • The 10% soiling rate represents a significant energy loss, so this kind of monitoring can help businesses decide when cleaning or maintenance is needed. It not only saves energy but also prolongs the life of the panels by preventing potential long-term damage from dirt buildup.
