RNRG’s Soiling Measurement Kit provides users with the information needed to quantify the site-specific impacts of soiling caused by snow, dust, and other particles on prospective and current PV projects. These data are used to improve pre-construction annual energy production (AEP) estimates as well as maintenance schedules (i.e., panel washing) and forecast models in the post-construction setting.

• Determine site-specific soiling loss characteristics with this turnkey soiling measurement solution.
• Install easily as an accessory to RNRG’s SRA System – complete with PV modules, pre-installed back-of-module temperature sensors, flexible mounting hardware, and integrated soiling interface module.
• Measure short circuit current and back-of-module temperature with user’s choice of statistical interval as well as optional 1 Hz sample data collection for flexible analysis options to meet data demands.

  • Three (3) 15W PV panels (data logger power, dirty panel, clean panel)
  • Two (2) back-of-module temperature sensors
  • One (1) interface module (in shelter box)
  • Related mounting and wiring components
