Beware of solar installers and their promises

A very bad experience with Orbipex Solar and owner/electrician James Mkweu. The solar off grid installation was done on Thursday and the solar panel installation team had no supervision and damaged my ceiling due to knocking on the roof tiles. Also not happy with the cabling from the panels to the inverter as rain can run into the ceiling as the pipe where the cabling runs through is not sealed. The earth Leakage switch is now tripping and the switches that he bypassed from the inverter, that will only use eskom are now tripping as well. His aftersales service is non-existent and the constant excuses that he is on the way, will be there shortly, etc are all lies. We made the mistake of paying the full invoice amount after completion of the installation as he promised to bring the COC certificate the next day - still waiting and I now wonder if he is even qualified to issue such a certificate, which we paid for and is charged for on the invoice. Please be very careful when choosing a solar installer - it is so difficult to find the right one and James was the only one from 7 that we contacted, who came to do a site inspection and give us a fair quote. All the others we contacted have not replied. We chose him because his first impression was good and he knows his stuff, but time management and aftersales service are non-existent.
