Our solar system was installed and only worked for a couple of weeks. Don't expect the warranty to cover anything! At my expense, an electrician tested the system, found the inverter faulty and stated that aspects of the installation were not completed correctly including unsecured wires in contact with the metal roofing. The electrician informed them but no rectification occurred. The inverter was replaced, again at my expense and the system worked for 2 days before displaying faults again that stopped it from working. Now they want me to pay again to have it repaired. DO NOT use this company at all go to someone else. I still do not have a working solar system
