If you have concerns with your solar power installation, the safest thing you can do is leave your system alone and contact the installer.
If you experience difficulty in seeking clarification or rectification of any issues with your solar power installation from the installer of your system, the CEC has a dispute resolution process. This involves the customer filling out a dispute form, and the CEC then investigating the written complaint.
The CEC has the right to investigate the conduct and work of any person holding accreditation. The CEC dispute form can be found here.
Contact the Fair Trading body in your state if you have concerns about the business practices of your solar company.
