Third-Party PV Condition Assessments for Commercial Rooftop Solar
Independent inspection and O&M services for building owners, asset managers, and institutional solar operators in NYC and the Tri-State area. NABCEP PVSI certified.
NYC's Commercial Solar Fleet Is Entering Mid-Life
Systems installed between 2014 and 2020 have reached a critical operational threshold. Many were commissioned correctly but have received no structured technical review since installation. Production variance, inverter aging, thermal irregularities, and roof interface deterioration accumulate silently.
Wadadli Solar provides the independent technical review that asset managers, building owners, and lenders need, without the conflict of interest of the original installer.

Every assessment concludes with a detailed written report, not a verbal summary or a checklist. Built for the asset owner, not the installer.
- Building owners receiving inconsistent production data from their O&M provider
- Asset managers preparing for portfolio refinancing or sale
- New owners of a building with an existing PV system
- EPCs verifying system condition before warranty transfer
- Lenders underwriting solar-inclusive commercial mortgages
Common Findings on Mid-Life Commercial Systems
Systems installed 2014–2020 show predictable failure patterns. Early detection prevents production loss and capital replacement costs.
Production Variance
Output below modeled expectations without obvious cause. Often traced to soiling accumulation, optimizer degradation, string configuration issues, or monitoring gaps.
Inverter Lifecycle Risk
SolarEdge and SMA residential and commercial inverters approaching or exceeding manufacturer expected service life without warranty extension.
Thermal Irregularities
Hot cells, bypassed bypass diodes, and junction box anomalies invisible to the naked eye, revealed by infrared scanning.
Roof Interface Deterioration
Penetration sealant degradation, racking corrosion, and drainage interference around the solar array footprint.
DC Termination Issues
Connector oxidation, improper torque, missing weatherproofing on exposed MC4 connections and combiner terminal blocks.
Monitoring Gaps
Communication failures, orphaned inverters, and unconfigured alerts that allow production losses to go undetected for months.
Case Studies
Real inspection findings from commercial systems in the NYC metro area.
Optimizer String Fault: Eastchester
String underperformance traced to a failing P400 optimizer creating a downstream PLC communication break. Confirmed via thermal imaging and GO diagnostics.
Inverter Communication Failure: Port Jervis
Multi-inverter site with RS485 bus break causing three downstream SMA Sunny Boy units to drop from monitoring. No production impact but monitoring gap undetected for 6 months.
Rodent Damage: Conduit Breach
Rodent nesting under a large rooftop array caused MC4 connector damage and conduit breaches on three strings. Discovered during routine O&M inspection.
