Customer Feedback
Very happy with my solar installation. They were very helpful when I received my quote, happy to explain any questions I had about the different options. His team arrived on time and done a fantastic job. Would highly recommend.
Thank you so much. We are very pleased with the work done by your expert friendly team installing our solar system. All the way through the job was done in a very professional manner. Will recommend to anyone else. Many thanks.
Everything from the initial contact to the installation of our Solar System and follow up were exceptional. They were on time and provided all the information we needed to make the decision to have Solar installed. The installation was done over two days with the utmost professionalism and quality.
They are good guys, they’ll talk to you plainly and has the patience to explain and not stick to industry jargon. He won’t pressure you (I waited over 6 months between his consult and my install, saving up funds needed), he’s quite happy for you to do own research and answer questions after that. I got 3 solar quotes, looked deeply into solar components in that time between. They got my business with quality components and a prompt install that cleaned up after themselves.
Excellent professional service, prompt installation. Highly recommend…
Absolutely fantastic company to deal with. I had a 6.6kWh Solar system installed. They were very knowledgeable, flexible, professional, and prompt. Sold the system by promoting their skills and not running down the opposition. System was installed 2 weeks after ordering and the workmanship was outstanding. The system performs better than expected.
