Go Solar poor service

Please think twice before you choose Go solar their after sales service is shocking and unprofessional. We have been with them a month an and the inverter has to be changed. Their technicians established the issue with the CT last week and arrive at my home without the part. Go solar who advertise hassle free maintenance tells me the suppliers don’t don’t have the part and don’t know when it will arrive. They are aware of issues and still send people to come fix something they don’t have a part for. They took a week to just get technicians out to establish an issue inform go solar of the issue three days later they arrive with stock and parts they knew they needed. Wasting people’s time
