That 25-year warranty printed on your solar panel proposal is one of the biggest selling points in the whole pitch, and in practice, it is close to worthless. I have

If you own a Tesla Powerwall and your battery spends its nights discharging down to 20% while your solar panels spend their days refilling it, you are losing money. This

There is a story going around that FPL’s time-of-use rate is a money printer. The pitch is simple. Add a battery, buy power for almost nothing overnight, and stop paying

A customer’s EG4 FlexBOSS 18 inverter was quietly cooking itself, and the EG4 monitoring app had absolutely no idea. That is not an insult to the hardware. It is an

Enphase quietly rolled out PowerMatch in late 2025, and I’ve been keeping an eye on it. It solves a real problem with how their batteries handle low loads. The catch

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!
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!
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
We originally had a photovoltaic system installed in 2007 by a company no longer in business. Now in 2025, we installed a home generator, so our electrical panel and the... ... photovoltaic connection had to be reconfigured to safely accommodate both systems. I found Florida Solar Design Group via Google. I was impressed by the stellar reviews and informative website - obviously, this company leans into research - an important component of an evolving industry. From my initial contact, their rapid response and the professional expertise of Jason Szumlanski & team resulted in safety issues solved, disconnecting and then reconnecting our system once the generator was installed. Even their work contract is clear & easy to understand. All at a very reasonable price. Highly recommend FSDG!
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!
Jason and his team are excellent I highly recommend this company they are the best in the buissness
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.
Jason and his team have been a pleasure to deal with throughout the process. As with any system of this complexity, there were a few glitches (mainly enphase related) however... ... Jason worked through start up process directly with factory and resolved all issues. Their team has responded promptly and professionally throughout. One of those vendors that you find now and then that you wish all others we like. We are 110% pleased with the system and end results. Be prepared to wait on FPL for permit approvals, etc. but in the end, it will get done!
I can describe my experience in one word - Awesome. I wanted a local company with longevity and I got it. No subcontractors just an experienced owner and... ... employees. They very responsive and were extremely helpful through the process.
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...
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.
The Florida Solar Design Group installed our rooftop solar system to power our new headquarters building. Their staff were very helpful, courteous, and professional.

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.
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 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.
