The Soiling Measurement Kit interfaces with the SymphoniePRO Data Logger via its interface module, which provides four 0 V to 5 V (analog) signal outputs:
• Temp LIMPIO
• Isc LIMPIO
• Temp SUCIO
• Isc SUCIO
The interface module requires a single 12 V excitation (EXC) and ground connection (GND) available from any combination of built-in logger channels (16-19) and P-SCM channels (20-26). P-SCM channels require P-SCM item 9132.
Benefits:
• Determine site-specific soiling loss characteristics with this turnkey soiling measurement solution.
• Install easily as an accessory to NRG’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.
Quantify the site-specific impacts of soiling on prospective and current PV projects with NRG’s Soiling Measurement Kit.
