Solar Energy - Stand Alone Power Sytems: Design & Installation


Stand Alone Power Systems (SAPS) can be a viable option for many applications, from a remote monitoring station to an off-grid household right up to village electrification. For the reliable, long-term supply of power to off-grid users, electrical workers involved with these systems fully understand the operating theory and safety requirements in order to design and install safe and effective systems, as well as adequately manage customer expectations.

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 (100 hrs)
  • Three day course at WITT/Infrastructure Park (24 hrs)
  • Post-course assignment (16 hrs)

This course builds upon the basic knowledge provided in Grid-Connected Photovoltaic Systems and expands upon that in Grid-Connected Battery Systems.
