In the company's T&C's they talk about passing over ownership of Energy Certificates (STC's), is this something that I should understand better before passing over ownership? Finn Peacock June 03, 2018 11:11 Updated Follow Nope - I explain why here. Related articles I noticed that some companies don't appear to be "accredited installers" with the Clean Energy Council. Is there a particular reason for this, and if the companies are not "accredited" what mechanism is there to get any faulty work rectified? Who does all the paper work and application for the installation? Does the installer need to be licensed to install the solar system? How will my off peak hot water service work with my solar system? How do I know what size system is best for me? Comments 0 comments Please sign in to leave a comment.
