How do I become an electrical contractor? Do I have to be an artisan?

I have developed a keen interest in Solar PV and would like to become involved in installing systems.
I have a T4 (heavy current ) from Vaal Triangle Technikon plus many years experience in the energy management field. For the past 14 years I have worked at an electrical engineering company that manufactures and sells industrial instrumentation.

Problem is I am 54yo and have a family to support.

Paul
