Clearly the article mislead one to believe that YOU MUST REGISTER WITH NBCEI - FALSE.
It is impossible to do a PV installation by yourself so you will definitely have a helper - If you have a helper he needs to be registered with NBCEI

It also states that only a IE or MIE can qualify and register to be an electrical contractor at DOL -FALSE. SPT can also qualify and register.
Yes a SPT ca n register as an electrical contractor but as a SPT registered contractor you cannot sign off on DC work as per Annex M

Also it mentioned that the point of control and the point of consumption, WHICH DEFINES AN INSTALLATION, has been removed. Again, FASLE. A LIE.

It is still there.
The doubt has been removed by the definition 3.16 - If the consumer installed and users the electricity then it is part of the electrical installation . The definition for Point of supply ( 3.58) and Supplier ( 3.77) has been updated and a consumers own PV plant is not a point of supply - Only a person that has contracted to supply electricity to another person is a supplier , like a shopping center owner. If the shopping center owner installs PV then he uses it for himself and is a consumer not a supplier. So the shopping center owner is both a supplier and consumer.
The detail is in the definitions before reading the clauses
The PV is in-between the point of supply and point of consumption and therefore part of the electrical installation
