Jason and his team are excellent I highly recommend this company they are the best in the buissness
I spent considerable time researching and designing my ideal solar + battery system and then reached out to 7 local solar installers. It turned out that 5 of them did... ... not have the expertise required to do what I wanted. The remaining 2 both seemed professional enough and gave me similar quotes, but it was Jason who really proved that Florida Solar Design Group was the right choice for me. There was no pressure and it was clear that he was extremely familiar with the specific hardware I wanted to use. He was also very patient and willing to educate me about how to operate everything. It has been about a week since everything has been completed and I couldn't be happier. I can power my entire 2500sqft house from battery for many hours during the night and then recharge using solar during the day.
Florida Solar Design group knows the solar business, and in working with them for many years for my clients' homes, they are only getting better. Given the numerous companies out... ... there providing PV systems, my wife and I wouldn't think of using anyone else when it came time to install PV on our home. When you speak to Florida Solar Design Group about your system, you'll be speaking to the owners of the company. That sets them far apart from the others. David Poorman, Naples, FL
This company is the best....I sent a message thru their website on a Saturday because I needed a new valve actuator installed. Jason called me back within 15 minutes (never... ... expected that) and told me he was in my area and could be here in 10 minutes. He came and installed the valve and my solar is up and running. That was the greatest thing that happened to me since the hurricane. Incredible customer service.
We had the Florida Solar Design Group install solar pool heating a few months ago. The buying experience was very professional and so was the installation. We would... ... highly recommend them if you’re considering a solar solution.
From the start FDG was a company I knew I wanted to work with. Even with a delay on my part because of the hurricane the job went smoothly from... ... start to finish. I can't say enough good things about Jason and his crew.
We are extremely happy with our complete dealings with Florida Solar Design Group. From the initial contact to the completed job (with Lee County electrical inspection, passed first time... ... with no issues). Definitely a first rate contractor. Do not hesitate to consider this company for your solar system installation.
I did a deep dive in researching solar companies that do business in Southwest Florida. Florida Solar Design Group rose from the very convoluted pack as the best. Only after... ... the installation was complete did I realize that they have to be THE very best. I'm very happy with my decision to choose Florida Solar Design Group.
We were so lucky to find Florida Solar Design Group. They are professional, courteous and clean up all the mess ( not that they made a mess). After the initial... ... installation, it wasn’t “take the money and run”. I, of course, had more questions and the owner came to my home to go over all of it again. That’s a plus in my book. I highly recommend this company 100%
We recently moved into our forever home In Babcock Ranch and hired Florida Solar to design and install a solar system four our new home. Florida Solar took care... ... of the permitting including dealing with our fussy HOA's and scheduled the installation. Their communication was excellent. The installation took less than a day and by the time the crew left we were producing electricity. Now that we are hooked up to the grid we have been producing a little more power than we are using and that is running to AC's. I am very pleased with our solar panels through Florida Solar Design Group and would definitely recommend them to anyone considering going solar.
Met with Dominick and went over a quote for complete solar system. Met with Jason afterwards and went over project. Project was installed when promised. Went over new system with... ... Jason and he explained everything. Very impressed with the professionalism of there installing crew and the quality of work. Definitely recommend Florida Solar Design Group!
Florida Solar Design helped us out tremendously. Jason is incredibly knowledgeable regarding solar systems. We needed to have a solar panel system removed and reinstalled as part... ... of a roof replacement. He provided a very thorough inspection report, and spent time educating us on things to be aware of, without a sales pitch for a new system. Very impressive and friendly service.
I can’t say enough about Jason, his staff and crew. The level of responsiveness is unparalleled, the level professionalism is typically unseen in this or any other construction industry. Jason... ... makes sure to walk the customer through the best options available. He educates his customers. Susan in the office was awesome! Very communicative and great sense of humor. It was the best service I’ve received of any contractor in the state of Florida. Pricing was excellent as well. I wish I owned more houses to put him to work more! Jason was also on-site at my home, and was readily accessible for any questions.
Super company! The customer service couldn't have been better. They made everything run smoothly and were very responsive to any of our questions.
I am not sure I can fully convey my satisfaction with Florida Solar Design Group and its owner Jason, but I will try. I began my solar 'adventure' while... ... constructing my new house, I thought I could 'do it myself' after all I was building my own house. Long story short after purchasing panels and inverter online and keeping them in storage before I was anywhere near to starting I wisely decided its not a DIY project, at least not for me. I wish to share my full experience, but not everyone maybe interested, if you feel inclined read on to the end. When looking to install Solar at a minimum do yourself a favor and speak to Jason. I highly recommend speaking with him after (or better - before) any sales pitch from another vendor - he will not give you a 'sales pitch' he will listen to your wants, tell you what is possible and at what cost. What is 'realistic' and what isn't. I think we have come to expect that solar is just something easy to do, slap some panels on a roof and your golden, but if you want more than just something offsetting your power, like solar power when we lose power (and who doesn't want that in SWFL) battery backup etc. it gets pretty complicated quickly. Experience and knowledge matters, not everyone can do it or has gained the knowledge to do it SAFELY. From my experience with Jason he has probably forgotten more stuff than some other installers even know, and his crews have many years of experience also. Always call Jason & FSDG you will learn a lot - and learning and being knowledgeable is very important when going solar to make sure you have a satisfactory experience and no regrets. So now for the full story of my install, Back in May of 21 I reached out to some installers and Jason was 1 of 2 that came to my construction site. I was immediately impressed with Jason's knowledge and he was frank and honest about what I had purchased, what was 'missing' (a fair bit) and what I could expect, of course this was less than my initial expectations. We kept in touch as the house was built, I sent some equipment back and with Jason's instructions ordered some other parts. My house construction was not going the smoothest (covid etc.) and the electrician just wasn't understanding what my plans were but we had sold our old home and needed to move in quickly so we finished up the house 'standard' then after another meeting with Jason came up with an electrical plan for what we really wanted which included adding panels for a larger system (my first pool home and I had no idea what those suckers run especially when heating them). After some further delay (NOT FSDG related) about a month ago we were ready for Jason and his crew. Jason came back out again (I think that may have been 6th time and there were countless emails) to confirm everything was ready and all the parts (his and mine) were ready, he got us on his schedule almost immediately. On a very hot Monday one crew ran the wiring in the attic while another was on the roof setting up and wiring the racks. It was a REALLY hot day on a metal roof, the wiring and inverter were ready to go but it was just too hot (southern and western exposure of course) to finish in one day - the poor guys probably lost 10lbs in water weight. Next morning bright and early they were back to finish the panels 50 of them in total. Jason came by a little later to supervise the final installing and hook ups and to make sure everything was right then by 12:30 he allowed me to turn it on - I don't think I have ever been happier to do almost nothing - its kind of surreal seeing the screen on inverter showing solar power and no grid power coming in. No noises of machinery, no bells and whistles just silent power to run all the other noisy stuff. I have batteries for partial backup and I look forward to figuring out my usage and getting ready for when I know the power will go out at some point - I am ready and in no small part thanks to Jason and FSDG. Thank you Jason & FSDG
FSDG went above and beyond the call of duty to diagnose and correct major safety problems that were caused by our original installer. (they not only incorrectly installed but... ... then they refused to fix safety issues since they said "it passed inspection"). WE ARE SO THANKFUL FOR FSDG. THEY MAY HAVE SAVED OUR LIVES!
