05
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).
06
In wind studies, PV capacity factor improvements from tracking can be substantial; single-axis tracking can increase annual energy by ~10–25% over fixed-tilt (peer-reviewed).

Across the solar value chain, degradation and performance benchmarks point to material long-term impacts, with crystalline silicon modules commonly declining around 0.3% to 0.8% per year and a P50 model assumption near 0.5% per year, while real-world gains from better conditions such as soiling control and tracking can offset losses through sizable yield improvements like 10% to 25% from single-axis tracking and 5% to 30% in dust-prone regions.
