Due to the lack of non-compliance to the required standards and legislative requirements the need has come about to address all of the material in the course content so that the correct application and installation practices are being put in place so that the technology receives its due credit and respect as a truly sustainable approach to green and cleaner energy solutions.
Are installers / EPC’s of Solar PV systems who are in desperate need to familiarise themselves with all relevant criteria for the optimal and compliant practices in the installation / erection, testing and commissioning of Solar PV systems.
- Electrician (IE and or MIE)
- Technician (Pr. Tech. Eng.)
