I’m 52 years old, I have an N4 and I do installations such as security biometrics, electric fencing and so on. I found the PV Off-Grid Technician course really valuable. I pushed hard to finish the course in one week, as I had taken leave, starting early in the morning and finishing late each evening. The virtual trainer suggested that I create spreadsheets to do calculations based on the formulas I learned as I progressed, and I’ve now automated a lot of tedious tasks by building these templates.  Neville A, South Africa
