RC22 PV Reference Cell

RC22 Product Photo 1 With Text


  • RC22 is the first PV reference cell specifically optimized for both bifacial and monofacial PV systems.
  • The ultra compact design allows easy mounting anywhere, including on the rear side of your bifacial array.
  • Wide-dynamic range, ultra-low zero offset, and dual calibration at both 1000 W/m2 (STC) and 135 W/m2 (BSTC) provide accurate measurements over the full range of irradiances seen by bifacial systems.
  • The RC22’s unique glass-to-edge surface design eliminates excess soiling versus conventional reference cells.
  • Integrated features support multiple mounting configurations.
