Customer Testimonials

"Incorporating sustainable energy into our home in order to reduce carbon emissions and save on energy costs was essential to our plan. We definitely made the right choice in using GreenTech Energy to install Maxeon Solar panels. The system is already overproducing, and I am receiving electricity bills of $0 each month. Saving the environment while saving money is a win-win for all."

Dr. Guy Harvey, Marine Artist & Scientist

“Their professionals were extremely helpful, and we are extremely pleased with the final structure which they designed. It not only provides enough solar energy for at least half of our needs but also acts as a protective covering over our pool deck. It is so aesthetically pleasing that most people don't realize that it is actually a solar PV system.”

Dr. Steve Tomlinson, M.D- Savannah Medical Clinic

“Our family’s decision to choose GreenTech Energy for the Maxeon installation at our new home was definitely the right one. The quality of service and professionalism from the GreenTech team, in addition to the advanced solar technology has far exceeded my expectations. I will certainly recommend GreenTech to all my friends and clients.”

Mike Stroh, President- TRIO Architecture
