Bad and sad incompleted solar installation that is not in line with the electrical and solar specifications

I learnt a very hard way in trusting an electrical contracting company by names of Power Plus Electrical to install solar paneling system on two dwellings on my smallholdings and I have had 3 quotes and unfortunately chosen the cheapest on reference from a friend who's home were done. The job was never completed and I was compelled by another Solar company to stop and dismantle all workings and disconnect all Sunnysink equipment as this was a fire hazard and total unsafe practice. I then have two other companies have a inspection done and all were shocked on the safeness and workmanship. The Sun - shade effect were not studied and isolators were left out and AC/DC become even a bigger fire risk. If a fire had to break out the insurance will not pay out - SO BEWARE IF YOU DO THIS EXERCISE MAKE USE OF A REPUTABLE INSTALLER. I also have a full report on this work that was carried out and rejected. A loss of 180k - sadly these guys don't answer their phones nor reply - be rather safe and sure before you do any of this
