South Africa's energy crisis has nothing to do with the global energy crisis. Unlike Europe we have more than 200 years of coal reserves. The crisis here is self-inflicted by poor decion-making and governance. Agree, when load-shedding eases, which is just a matter of time, then solar installer rates will converge to that of electrician rates. Their current rates are reflective of the high demand. What will also drive rates lower is the many non-solar electricians are furiously reading/learning on how to install inverters. Hence supply of these skills is bound to increase.

This is looking good. Have you done a rough payback period calculation? [how long a period until your electricity will be free]

Quote is inflated. Better to source the equipment yourself and get an installer.
