We lost antenna signal To our TV sets on the day of installation of solar Pannels. When complained about this issue , SEM electrician refused to acknowledge the problem could be the result of their procedure. They demanded call our fee plus hourly rate to fix the antenna. Now received a message seeking access to review invetors as they are not working. I can only say that the professionalism was less than I would have expected of SEM team. Expensive LG Pannels were selected to avoid substandard vendors offering cheap solar panels. I hope from here on the process is smoother.
