Green Sparks were the only company that came out to look at the job. Others just googled our home and priced it over the phone. We were made very aware of the difference between solar panels and realised other companies were selling off old technology. Paul was also the installer. He was there when he said he would be and the price quoted was the price we paid. We have saved thousands of dollars since our installation, and we can still call Paul if we have any questions. Green Sparks are A1 ++++
