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 August 23, 2017 05:05 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? Does the installer need to be licensed to install the solar system? What is a Tier 1 Solar Panel? How do I estimate the energy output of a solar system throughout the year? My installer says it's fine to have different roof orientations on the same string. Is he correct? Comments 0 comments Please sign in to leave a comment.
