What is Soiling loss? This term refers to the power lost due to snow, dirt, dust and other particles that cover the PV module surface.
The short-circuit current, essential characteristic of the PV panels, is proportional to the PV panels effective radiation. By comparing the short circuit current of a “clean“ PV panel to the “soiled“ PV panel, and compensating for PV panel temperature we can estimate the exact effect of soiling.
The Soiling Measurement Kit supplied by Kintech Engineering allows users to estimate the site-specific effects of soiling on PV modules. (Will be available soon)
