A practical inspection guide for solar photovoltaic projects — covering module quality, materials, installation, electrical integrity, testing and commissioning from factory to site.
01. PV Module Inspection
Check module type, dimensions, materials, workmanship, labeling, serial numbers, visual condition and manufacturing quality.
02. Factory Inspection
Verify production processes, approved materials, quality controls, EL testing, flash testing and factory acceptance requirements.
03. Incoming Material
Inspect modules, inverters, mounting systems, cables, connectors and major components against approved specifications.
04. Installation Quality
Verify module alignment, mounting, torque, cable routing, connectors, earthing and mechanical installation quality.
05. Electrical Inspection
Check DC strings, polarity, insulation resistance, grounding, cable condition, connections and electrical safety requirements.
06. Testing & Commissioning
Review IV curves, insulation resistance, continuity, performance, inverter operation and commissioning records.
Solar PV inspection should be performed against approved project specifications, manufacturer’s requirements and applicable international standards, including IEC 61215, IEC 61730, IEC 62446-1 and relevant IEC standards for photovoltaic systems.
