Losses from soiling can reduce PV energy yield by a measurable % depending on region; peer-reviewed studies report 5–30% impacts in some dust-prone areas (systematic findings).https://www.sciencedirect.com/science/article/pii/S1364032116300848

Interpretation
Performance Metrics Interpretation
For performance metrics, the most telling trend is that widely used benchmarks assume crystalline silicon degradation around about 0.5% per year and typical well performing systems show PR values of roughly 0.75 to 0.90, meaning real world yield is shaped as much by steady yearly module losses and overall system efficiency as by variable factors like soiling that can cut output by up to 30%.
