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.
Great system, and great people who continue to respond in a timely manner to all questions.
Highly recommend this company! We have been working with Dominick and Jason for a while now when they installed our solar years ago. They made the whole process seamless,... ... explained everything in detail to us. Since then they have been servicing our solar and are always so wonderful to work with. Responsive, quick, and always a pleasure to work with. Recently we had Manny come out to do a technical repair and he was just as great to work with.
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
I found Florida Solar Design by searching for the manufactures Enphase, Rec, and Span. I already had a Generac Generator that I wanted integrated into the final system. ... ... This is the best service I have ever had from any vendor. If it wasn't for my insurance certificate issue this project would have been done in 2 weeks. I am fully functional with net metering in under one month from the time their first trucks showed up. Fast, friendly, clean, and respectful. Thanks for the great service
