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.
Commercial SolarEdge O&M and Diagnostics
Wadadli Solar works across multiple commercial inverter platforms, but approximately 80% to 85% of our field work is centered on three-phase SolarEdge systems. That concentration has built practical familiarity with inverter faults, monitoring and communications issues, optimizer troubleshooting, enclosure repairs, legacy equipment, and corrective O&M strategies for commercial and community-solar assets.
If you operate a commercial SolarEdge system and need an independent inspection, fault diagnosis, monitoring recovery, optimizer support, enclosure repair, or a practical plan for an aging system, contact Wadadli Solar.
Need Help With a SolarEdge System?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.

Learn moreWhat You Receive After an Inspection
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 field findings: commercial SolarEdge systems in the NYC metro area, and off-grid, battery, and monitoring work in Antigua & Barbuda.
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.
Enclosure Repair Avoids Full Inverter Replacement
Corroded three-phase inverter cabinet repaired in place using evaluated, compatible legacy hardware from decommissioned SolarEdge inventory, avoiding the cost and downtime of a full inverter replacement.
Redundant EG4 Off-Grid System With Manual Bypass
Two EG4 6000XP inverters and outdoor battery storage, paired with an external contactor changeover instead of relying solely on internal automatic transfer switching, so a single inverter fault never leaves the property without a manual backup path.
Legacy Off-Grid System: Instrumentation Retrofit
Rather than replacing an aging standalone inverter and LiTime-type battery bank, a Victron battery shunt and Emporia circuit monitoring were added to reveal actual battery, household, and circuit-level demand.
