Course description

The PV System Installation Training Course is a one week course, taught in fulltime (35 hours) for a class of 12 trainees. The morning sessions are devoted to theory classes and concepts discussions, while the afternoon sessions focus on hands-on practical experience, including system sizing,

installation and measurement of PV modules, inverters, charge controllers, and complete PV systems. The last session of the course includes a written assessment for evaluation of the learnt skills.

The contents of the theory classes are listed in Table 1. Although it includes a general overview of solar radiation, PV fundamentals and a short module on system sizing, the special emphasis of the course is given to practical installation issues related to system configurations, components, wiring as well as safety precautions. The course bibliography includes general texts on PV installation [1, 2] as well as specific instructions regarding safety issues [3] and a guidebook especially developed for this course [4].
