Commercial Array Cleaning
Accumulated soiling is one of the most consistent and recoverable sources of commercial PV production loss. NYC rooftops face seasonal pollen loads, HVAC exhaust deposits, and urban particulate accumulation that compound over months without structured intervention.
We assess soiling levels during every PM visit and recommend cleaning intervals based on observed contamination patterns, system tilt angle, and local exposure conditions. For flat-mount commercial arrays with low self-cleaning tilt, annual or semi-annual washing is often cost-justified.
What Array Cleaning Addresses
- Differential soiling causing string-level performance mismatch
- Seasonal pollen and dust accumulation on flat-mount arrays
- HVAC exhaust and rooftop debris deposits
- Bird dropping hot spot risk on individual modules
- Pre/post cleaning I/V curve comparison for production verification
- Cleaning interval recommendations in written O&M reports
The Cost of Unmanaged PV Systems
Commercial solar systems without structured O&M lose production silently. The losses accumulate before they become visible.
Typical recoverable production loss from soiling on flat-mount commercial arrays in NYC; cleaning is often the highest-ROI maintenance activity
Total production loss on unmanaged mid-life systems combining soiling, communication failures, and degraded optimizers
Average time a communication failure goes undetected without active monitoring management
Insurance or warranty recovery without documentation; written O&M records are your proof of due care
We Work for the Building Owner
Many O&M providers are affiliated with the installing contractor, the equipment manufacturer, or a leasing company. That means their service recommendations are not always aligned with the owner's best interests.
Wadadli Solar has no install affiliate, no equipment sales, and no manufacturer relationship that influences our reporting. Our recommendations are based on what the system actually needs, not what generates the most service revenue.
