SoilLog Optic is an advanced Optic Soiling Monitoring System developed by SuryaLogix to accurately measure the impact of dust and environmental contaminants on solar PV module performance. Over time, dust, sand, pollen, bird droppings, and other airborne particles accumulate on PV modules, reducing the amount of sunlight reaching the solar cells and resulting in lower energy generation.

The SoilLog Optic system continuously monitors this effect by measuring the amount of light passing through a reference glass surface. As dust accumulates on the glass, light transmission decreases, while the amount of reflected light detected by the optical sensor increases. By continuously analyzing these optical changes in real time, the system accurately determines the level of soiling affecting solar modules.
