These guys are the best of the best. My battery install came out clean and professional. They even corrected all of the issues the original installer created. Overall, great price... ... with amazing installers. Can't go wrong.
I wanted to throw a shout out to/for Florida Solar Design Group ~~ locally owned & based right here in Gateway. My husband & I decided to invest in solar... ... panels for our roof to alleviate the ever-increasing FPL bills over the long haul as well as ensure we’ll have power during any future power outages. I cannot say enough things about FSDG’s owners ~ Jason & Dominick ~ who were honest, transparent, and extremely knowledgeable throughout the process — from initial meeting to permits to install & beyond, as well as Susan who helped make sure things continued to flow administratively throughout the process. They listened to our needs, offered a couple of options to consider, then based on our decision, they designed & installed a system that would meet our current & future needs, as we’re having a pool built this fall. They did not try to sell us something we did not need, but were extremely helpful suggesting alternative, more useful options to what we *thought* we’d want/need. Dominick even provided suggestions for pool equipment specs to look for so we’d get the most out of our solar energy year-round vs. the partial-year, single purpose thermal pool water heater. Installation went flawlessly, our system has been up & seamlessly producing energy for a few weeks now. And we’re seeing the energy production daily through the intuitive app for the system. We’re REALLY looking forward to the next FPL bill which should be next to nothing. It’s comforting to know that — if the power grid goes down while the sun is shining — we’ll still have power thanks to the way FSDG designed our system. Absolutely NO regrets! Thank you FSDG!
Our neighbors had ADT put in their solar panels months before us and they are still not up and running. Our system is working great! Jason and Dominick... ... are badass...

I was calling around to find a contractor in the area that could help one of our clients troubleshoot an issue with their system. I work with a contractor out... ... of state and we are no longer in FL. Not many people were willing to take this on for us. I spoke with Jason and he was very professional and helpful. Even in their busy schedule, he was able to help our customer out in a timely manner and was very transparent with us about the whole process and what needed to be done. Would definitely recommend them!
Hello, my name is Drew and I live in Naples, FL. I wanted to provide a review of my experience having a photo voltaic energy system installed. The system I... ... had envisioned included a ground mount system with 32 solar panels, 3 Enphase batteries for storage and an existing whole house generator redundant backup. I was having difficulty with the sub-contractor who was installing my system, a Lotus something out of the Orlando area. Things were progressing very slowly if at all. I had mentioned this with my neighbor who called me over because she had a “solar guy” looking to fix her system as well. I met Jason of Florida Solar Design Group. He told me that he had 13 years experience working with Enphase systems. He offered to look at my system even though I was under contract with another company. After listening to Jason’s comments, I called my contractor and to my surprise, they knew each other. To make a long story short, Jason was hired to replace the existing sub-contractor. He corrected the wiring issues: the sub-contractor had removed all the color coded wiring to the generator and replaced them with all black wiring that were hooked up incorrectly and caused the fuse to trip every time the generator was tested. It also burned out the circuit board on the generator. He worked directly with my Generac dealer to ensure that everything was corrected. He also worked with Enphase to set up my system’s communication with Enphase and see that it worked properly. My takeaways from this experience is deal with someone who gives honest advise and stands by their word. Thank you Jason.
Florida Solar Design was great throughout the job. Starting with my call for an estimate—to the last day when they finished up and helped orient us to the new system—the... ... crew was knowledgeable, professional and efficient. Great experience!

Outstanding experience from beginning to end with Florida Solar Design Group. Dominick Zito was very responsive in meeting with us and designing the appropriately sized system for our needs. Susan... ... handled all the permitting and FPL applications, and Jason was onsite for the installation and to ensure everything was working properly. Jason was in constant contact with me throughout the installation, reviewed how everything worked and got me setup on the Enphase app so we can both monitor the system performance. I would highly recommend going solar with Florida Solar Design Group.
