Installation Quality Control: Common Mistakes

Quality control (QC) is about preventing problems through consistent checks during and after installation. Many PV failures are traceable to a small set of repeat mistakes.

Examples of issues QC can catch

  • Loose terminations
  • Damaged conductor insulation
  • Misrouted conductors (pinched, under modules, sharp edges)
  • Missing/incorrect bonding hardware
  • Poor labeling or missing documentation

A disciplined QC process reduces callbacks and improves safety.
