Part 3: Factory Audit Reports – Our Manufacturing Under International Scrutiny

Singfo Solar maintains a transparent and audited manufacturing environment. Here is what our factory audits confirm:

Quality Management System – ISO 9001:2015 Certified

Our Dongguan facility operates under a fully documented ISO 9001:2015 quality management system covering the entire production chain: raw material incoming inspection, battery cell sorting, module lamination, curing, framing, junction box assembly, final testing, and packaging. Regular surveillance audits by independent certification bodies ensure continuous compliance.

Intelligent Manufacturing Execution System (MES)

Our production lines are equipped with MES that provides real-time quality monitoring, full traceability, and production data logging. Every module leaving our factory can be traced back to its original raw material batch.

Rigorous Reliability Testing

Our in-house testing laboratory and third-party audits (TÜV & SGS) confirm that our products successfully pass:

· Thermal cycling test(IEC 61215-compliant) – simulating extreme day/night temperature variations

· Damp heat test – verifying performance under tropical and humid conditions

· Mechanical load test– confirming structural integrity under snow, wind, and hail loads
