Overview

The Cell Wash™ Automated Reference Cell Wash System, shown in Figure 1-1, washes Atonometrics 
RC22™ PV reference cells on a regular schedule.  
The Cell Wash system can be used as a standalone soiling measurement system to measure clean 
and soiled reference cells for comparison and soiling analysis, for example as shown in Figure 1-2.  
It can also work as an accessory to the Atonometrics RDE300i™ PV Module Measurement System as 
part of a more complete module performance and/or soiling measurement system. 
Cell Wash can be used for both monofacial and bifacial PV systems.  
Communication to your data logger or SCADA system is via Modbus RTU (RS485). 
For more details on using Cell Wash as an accessory to RDE300i, see additional information on 
support.atonometrics.com, including the Ordering Guide (880100) which shows details of possible 
system configurations.
