Field Inspection Guidelines for PV Systems

This 2010 update to the 2006 edition consolidates the most import aspects of a field inspection into a simple process that can be performed in as little as 15 minutes. Explanations and illustrative pictures are included to instruct the inspector on the specific details of each step.

The ultimate goal of this guideline is to provide a basic knowledge of how to inspect a PV system so that a field inspector can take this framework and develop the experience necessary to perform these inspections quickly and thoroughly. Too many badly designed and installed PV systems have been approved to date. By clarifying the issues of concern, and providing a detailed checklist for the field inspector, fewer poorly designed and installed systems will be approved. As local inspectors become familiar with typical products and sound installation techniques, contractors doing marginal work will be forced to improve or find another line of work.
