Why traditional snow clearing does not scale
Different teams and timing lead to uneven
clearing and unstable winter performance
results.

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.

Mechanical snow removal
Designed to clear accumulated snow from PV glass with
a visible, repeatable clearing result
Zero-downtime operations
Timely clearing keeps arrays generating across the season
and reduces winter risk exposure.

Rooftop PV on industrial buildings faces additional constraints
during snowfall: roof load limits, restricted access, and safety
requirements. Waiting for natural melt can leave systems
offline for extended periods.
Mechanical clearing supports controlled winter operation:
timely removal, reduced load exposure, and predictable
recovery after events.
