I spoke with a number of vendors for a larger solar energy system at my new home and chose Greenfield Energy because of the teams professional yet friendly approach and most importantly outstanding product knowledge. Jack took the time to address my many questions and concerns from the quote process through to post installation. I found him to be a great communicator and did what he said he would do, on time. Jack and the team really did go above and beyond my expectations, very comfortable we chose them for such a large and important investment.

Fantastic and professional business to deal with.
Jack explained everything in simple terms and found him to very reasonably priced and was in no way a pushy salesman like others I dealt with. We had issues with the roof so Jacks assistance in getting a professional and reasonably priced roofer helped the whole process move along quickly and hassle free. I cannot recommend Jack and his team enough as the whole process from quote to finalisation was a stress free experience and to be honest I wish I had installed solar sooner.

Jack from Greenfield was great to deal with, quick to supply a quote and once the quote was accepted, the install followed soon after. Jack set up our system and ensured we had use of the app on our phones! I would highly recommend Greenfield energy to anybody wishing to instal solar!

Jack showed us how we could save with solar and offered us different options based on what we could afford. We were really excited about saving from our utility bills. The installing crew were clean and respectful of our property. They kept their distance especially when I informed them that my mother was not in good health.

Jack and his team recently installed a 5.1kWh system on our property. We're very happy with the workmanship, professionalism and most importantly quality of the parts used. He guided us through the entire process, gave us a good idea of what to expect and when we had a few questions after installation, he took the time to call us back and answer all our questions. I can't speak for other businesses but he's worth every dollar. We wholeheartedly recommend Greenfield Energy to our neighbours who want a professional installation by someone who cares about our home.
