Adders (equip/labor/de-icer) are extra as applicable.
Chemicals, water logistics, and pad cleaning adders billed as used.
Soiling assessment:
Visually inspect the array and, when possible, compare cleaning needs to monitoring data to confirm soiling losses.
Professional, module-friendly cleaning:
Use soft-bristle brushes, approved cleaning tools, and low-pressure water where appropriate.
Use deionized or filtered water where required to minimize spotting and residue.
Avoid harsh chemicals and abrasive methods that could damage anti-reflective coatings or glass.
Access and safety control:
Set up safe work zones, signage, and access routes.
Follow site-specific safety requirements for working around energized equipment.
Quality check:
Walk the array after cleaning to confirm coverage and identify any cracked glass, broken frames, or other damage uncovered during washing.
Document before-and-after conditions with photos when requested.
Clean glass lets more light reach the cells, which directly boosts kWh output.
With soiling removed, performance data reflects true system health instead of just dirty panels.
Proper cleaning helps preserve coatings, reduces staining, and keeps debris from building up at frame edges.
A clean array presents better to investors, off-takers, and the surrounding community.
Snow load and access assessment:
Evaluate site conditions, snow depth, and access before moving equipment or personnel.
Identify critical paths, inverter locations, and emergency access routes.
Safe, equipment-friendly clearing methods:
Clear access roads, inverter pads, and critical walkways with plows, blowers, or shovels according to site rules.
Use module-safe tools (such as snow rakes with non-abrasive heads) on arrays where manual snow removal is approved by the owner and equipment manufacturers.
Avoid aggressive methods that could crack glass, bend frames, or damage wiring.
Drainage and refreeze awareness:
Pay attention to where melting snow will flow and refreeze, to avoid ice hazards near equipment and walkways.
Report any areas where snow and ice accumulation could threaten conduits, cable trays, or racking.
Communication and documentation:
Coordinate with the owner or operator on when to mobilize, based on weather forecasts and production needs.
Provide photos and brief notes after major snow events and clearing operations.
Removing snow from critical areas helps the site get back to generating power sooner after storms.
Managing snow loads and ice helps protect racking, wiring, and walkways.
Maintaining clear access during winter ensures that service crews and emergency responders can reach everything they need.
Seasonal snow removal agreements with “trigger” points (e.g., mobilize at a set depth).
Combined snow and winter safety inspections (checking for ice damage, loose hardware, and winter-related wear).
