There is a public group on Facebook that was created by an Australian installer to highlight bad solar installations in Australia and New Zealand. Over the years it has grown to become a community where people can ask questions regarding quality of panels/inverters or any too-good-to-be-true quotes. Also you could post any job enquires directly as the site is visited regularly by installers sharing their nightmare installations.
We, at Aussie hybrid solar, encourage people to post their experiences with solar in this website, whether they are good or bad. Using the power of social media, we can help promote the benefits of going solar and at the same time help people when doing their research before accepting any quotes from cowboys in the industry.
