Grid-Connected Photovoltaic (GCPV) Systems are becoming a frequently requested option on many homes and in larger, commercial applications.

It is essential that electrical workers involved with these systems fully understand their operating theory and safety requirements in order to both design and install safe and effective systems, as well as fault-find and maintain existing systems.

Course Structure

The delivery of this course is designed for busy tradespeople who do not have the time to attend lengthy face-to-face courses.  The online component is fully flexible to allow students to complete the theory in their own time.

  • Pre-course learning:  Online self-directed learning at your own pace, with tutor support (96 hours)
  • Three day course at WITT/Infrastructure Park New Plymouth (24 hrs)

This is a pre-requisite course for other advanced courses for those wanting to insall battery-backup (on grid) or complete standalone (off-grid) systems.
