In snow-heavy regions, PV arrays may face two compounding effects: mechanical
load from accumulation and uneven shedding, and electrical mismatch from partial
coverage. Partial illumination can limit string current and contribute to localized
heating (hot spots), increasing stress over time. Timely clearing helps reduce both
prolonged load exposure and uneven-irradiance periods.
