I underwent a training encompassing two aspects . Practical one, represented by the initial site visit in which needed measurements taken, followed by sketching using SketchUp. Subsequently, we presented the proposal to the client, who, in turn, provided the necessary documents to proceed with the installation request. This constituted the other facet of the training which is submitting transactions.The installation involved establishing criteria for front and rear elevations of the system, and overseeing the inverter's operation. My preferred aspect of the training pertained to testing and commissioning, where I learned diagnostic procedures to identify issues impacting the system, leading to either decreased efficiency or an increase in the customer's monthly bill such as IV-curve test,Thermal imaging, continuity and Megar test.
