Florida Solar One is #1

Ray is a excellent engineer and a great communicator. He and his team engineered and installed the perfect amount of solar panels for my needs. After running the system for a few months he then sized and installed 3 powerwalls, setup all the software and gateways right down to the details on the app on my phone. His followup on the project, timeliness to complete, job site cleanliness, and overall friendly service is first class. If you are looking to get solar and/or backup batteries Ray and Forida Solar One should be your first choice.

Tesla powerwall installation

I recently had Florida Solar install a battery system at my house in the Florida Keys, and I couldn't be happier with the results! From start to finish, the process was smooth and efficient. The team was professional, knowledgeable, and truly went above and beyond to ensure that the installation was tailored to my specific needs. Not only does the battery system provide reliable backup power during outages, but it also allows me to maximize my use of solar energy, even during cloudy days. I've noticed a significant reduction in my electricity bills since the installation, which is a huge plus. Overall, I highly recommend Florida Solar for anyone looking to invest in renewable energy solutions. Their expertise, quality products, and exceptional service have made them stand out as a leader in the industry. Thank you, Florida Solar, for helping me take a step towards a more sustainable future!

Debra Babich | Key West, FL | 11/12/2023

Excellent Company!!!

Ray and his team at Solar One did a wonderful job installing our system!!! From our first meeting, Ray explained exactly what we were getting. The work was performed in a timely manner and we were in full communication about every step. They made sure we knew how to use the app and how to get the most out of our system. Very professional service!!! When we had a small problem with the system they were quick to remedy it. We highly recommend Solar One to anyone considering solar! Our energy bills have already been reduced considerably!!!!

Clark A. | Marathon, FL | 10/02/2023

Quick & Easy Installation

Ray Johnson has extensive knowledge and experience with solar panels. He know exactly how to design a system and complete the permit process. He is punctual with his appointments and responsive to any concerns. Most importantly, he uses his own "in house" installation crew that did an amazing installation. I give this company my highest recommendation.

Christopher Ellis | KEY WEST, FL | 05/16/2023

Great job, thanks.

Jeff | Big Pine Key, FL | 04/23/2023

Off the Grid in Big Pine Key

Ray and his team at Solar One did a fantastic job installing my solar panels and powerwalls. Ray took the time to do two site visits and spent several hours explaining everything I wanted to know and educating me from start to finish on the system, the components and exactly what I could expect from my solar install. All my expectations have been exceeded. My only regret is that I didnt call Ray sooner.

Eddie G | Islamorada, FL | 04/05/2023

Perfect Install

Start to finish the job was completed exactly as described in the contract. My job was completed in August of 2022. I am currently experiencing a surplus of energy production every month! Thanks Florida Solar One

Charles | Summerland Key, FL | 03/15/2023

Amazing service!

Florida Solar One did an amazing job for our house in the Keys....They were ahead of schedule, always clear in their communications and seemed to have a crystal ball that lined up their efforts, inspectors and the weather....no small feat for Florida! My only 'complaint' is they don't have a branch in Seattle to do our other house! Thank you again to Eay and the Solar One team

Steve Frahlich | Marathon, FL | 01/24/2023

Ray was very good to work with and everything he promised was delivered. I would recommend him to anyone considering solar panels.

Frank | Key West, FL | 11/11/2022

We highly recommend Florida Solar One for Solar Panel installation in the Florida Keys! Ray is very knowledgeable in the field and was able to problem solve and strategize each scenario. Cortez and the rest of the installation crew were courteous, efficient, and tidy! Ray has checked in with us multiple times post-installation. We were very pleased with our experience!

Key West Nate | Key West, FL | 08/01/2022

Best decision I've made

Ray and his crew got it done quick. 30 panels and two Tesla batteries permitted, installed and inspected in a couple of weeks. We are off the grid and have 3-4 days of backup power. Workmanship was pro, neat and well thought out. Very happy.

Russ | Summerland Key, FL | 02/28/2022

Flawless Residential Project in FL Keys

Here is my story. I spent over a year researching solar companies and products. I am a retired Army pilot so I am very no nonsense and direct. I tried to learn as much as possible about the products so I could ask the right questions. It was difficult because it is like learning another language. I learned enough to make me dangerous. I could ask most of the right questions and I felt very few companies could answer them all (mainly because I was speaking to salesmen). Out of 7 different companies in my area only 1 stood out and answered all my questions plus some I didn't know. Florida Solar One (Ray Johnson) was professional and thorough. At times he would speak way beyond my knowledge base but was able to break it down to layman's terms when needed. He was a direct and no nonsense kind of guy. When it was time to start the project his team was on time, very respectful, and dealt with the county permitting department with speed and accuracy like no other company in the Keys. I have neighbors who started their solar projects before me and are still waiting on county inspections. My project products were- Mission Solar Panels, Enphase IQ7a micro inverters, Tesla power walls. All rated for Hurricane area. From start to finish for my project was 2-3 months- 1 month permit approval, 1 week install, 1.5 months for county and electric company inspections. 100% recommend Florida Solar One- Knowledge, Professional, Price, and able to work with county inspectors to get things accomplished in a timely manner.

Rami Razouk | Big Pine Key, FL | 02/02/2022

Outstanding job of installing solar panels and Powerwalls

Ray and his Florida Solar One team did a fantastic job of designing and installing a 27 panel solar system with two Tesla Powerwalls on our Big Pine Key home. Ray is incredibly knowledgable and experienced. By looking at our A/C system and the rest of the house he could quickly determine what we were going to need. Gave a great quote and really stuck to the budget, even as solar panel prices went up. The work was done quickly. His team did the installation without us being there, and they left the place in fantastic shape. They took great care in where to place the equipment and how to wire it. Highly recommend Ray and the team, especially if you are going to get batteries.

Key Largo solar power | KEY LARGO, FL | 11/24/2021

solar in the FL Keys

FL Solar One is very knowledgeable and helpful with all decisions concerning solar energy. Ray Johnson is on site and involved in all work being done and uses a great crew.

Lee Winter | KEY WEST, FL | 02/27/2021

Expect the Best!

Ray and his team installed a 30-panel, dual Tesla powerwall system at our home in the Lower Keys. They were prompt, professional, and highly skilled technicians who keep you informed every step of the way. Best of all, you get the results they promise without any of the hype. Our home is now ready to "weather the storm" when the grid goes down (think Texas). What a pleasure seeing the electric bill each month! Great job, Florida Keys Solar One!

Don Mayer | Key West, FL | 11/03/2020

Professional, honest and personal

I chose Ray Johnson and Florida Solar One for my PV system and Tesla PowerWalls because Ray was a pro and knows his stuff. Others were fast talking hustlers but Ray knew the landscape. He understood the difference between net metering and avoided cost, he knew the players at the utility and city and he got the job done. I was amazed at how quickly the installation went and the careful details of the installation. I highly recommend Florida Solar One and Ray Johnson!

Steve Brenner | Key West, FL | 06/14/2020

Expect the best from Florida Solar One

Go ahead and get a quote from other solar companies....But don't hire anybody but Ray Johnson and his crew! Not only are they the most Knowledgable, Professional, and Meticulous contractors in the Keys but he continues to follow up and ensure my system remains at peak operating performance. Ray, very patiently, explained any and all questions I had as a novice in solar energy production. Ray and his team installed 41 solar panels and 3 Tesla Powerwalls on our house in Old Town Key West dealing with all the permit requirements including the Historic Architectural Review Commission. I could not have asked for a smoother project, and recommend Florida Solar One very highly!

Mark L | Key Largo, NJ | 03/06/2020

Great team to work with!

We talked with a number of solar installers and decided to use Ray Johnson and his team because they were so thorough and helpful in the discussions leading up to hiring them. Everybody else gave us their standard sales pitch. Now Ray has a proposal package too, but he patiently listened to all of our concerns and questions and responded honestly and completely to each and every one. He talked us through every option and choice and provided insights honestly. He actually recommended a somewhat smaller system than others had based on how we were likely to use it. Then when the time came for installation, he and his team were prompt, professional and neat. They timed everything perfectly with the inspectors and power company and we were up and running in days! Highly Recommended!

Florida Solar One Review | North Miami, FL | 07/22/2019

My Solar One Experience

Florida Solar One did an excellent job period. They were far less in cost than any of their competitors and the work was first rate. They installed my panels, inverters, and other misc solar components without issue. The system has been working perfectly for about 3 months now and is basically zero maintenance. Ray and Jose know their stuff and delivered exactly what we agreed would be right for my house. I would recommend them to anyone looking to add solar to their home or business.

Steve | 07/07/2019

Awesome

We purchased a vacation home in the Lower Keys. Florida Solar One was my first call for large projects we wanted to do. Ray is incredibly knowledgeable about every aspect of solar, from how it works all the way down to which type of fastener to use for my type of roof. My goal was to completely eliminate my electric bill and although I have not had it on her for a full billing cycle, I’m producing well in excess of what I need. In addition to the solar they also installed two Tesla Chargers and when Keys Energy came out to hook their meter up, even they were excited to see those, as they want to understand the impact electric vehicles will have on their loads. Apparently we were the first residential Tesla Chargers that they knew of. Overall, highly recommend FS1. And a big thanks to Jose for all of his hard work in making this happen.

D Jankov | 08/27/2018

Jankov Residence

When searching for the right company to design the Photovoltaic system in my new home, I came across Florida Solar One. What caught my eye was they had education classes for installers on how to design and implement the right system. I contacted them and was pleasantly surprised how knowledgable and technical they were. Being an engineer myself, we were able to speak the same language. They also understood that technology was constantly changing and that new products pop up all the time. They spent the time to evaluate the products they use along with the ones I suggested to determine if it was the best fit for my solution. They did not try to shove any cookie cutter solution down my throat like most others I spoke to. Once the home was ready to be connected to the power company (FPL), they walked me through all the paperwork and got me approved to produce power very quickly. Now I have one of the nicest installations in the neighborhood, and I can power my entire 4600 sqft home along with my electric vehicles. This is the only company I would recommend for solar in Southern Florida , since they really know what they are doing! I would encourage homeowners in other parts of the country to hire them as well, since it is a long term investment and you don’t want Holmes to have to “Make it Right” a short time later.

Art Tumolo | Tavernier, FL | 08/24/2018

FS1 is fantastic

When I moved to Florida and bought my house I decided that I was going to install solar panels for electric generation. Moving from Maine it seemed like a no-brainer. I started my research from scratch. I knew nothing about solar. I eventually called Florida Solar One and spoke to Ray Johnson. Amazing breath of fresh air. Ray was extremely knowledgeable and took the time to answer every question, no matter how stupid or how many times he had already answered the same question. Ray instills trust. I eventually joined a local Solar Co-op and joined the selection committee. This gave me the opportunity to do in depth research into a number of solar installers. That experience cemented my decision to choose FS1 for my installation. I am very happy with the installation done by FS1. They were some of the most professional people I have worked with. The timeline of the installation was exactly as Ray had laid out to me. They were prompt and thorough, and Ray took time out to explain what was being done as the work progressed. I am extremely happy with the results, and the system is overproducing and exceeding my expectations.

Todd T. | Pompano Beach, FL | 08/20/2018

Professional Installation

I did my research before deciding to go with Florida Solar One for my Solar project with Battery back-up. Ray is very knowledgeable and was hands on during the whole installation. His crew of Cyle, Dave and Jose were just fantastic in all respects. We went with 30 Sun Power 320W Panels, Pika PV Links, Pika Harbor Plus Battery and Pika Island Inverter. I am very pleased with the outcome. Prior to FPL installing the Net Meter I ran all of my critical loads with just the Solar Panels and Battery for 3 days as a test. Battery level never dropped below 30% before the solar output topped it off quickly the next morning. The average daily production over the past ten days has exceeded our consumption even with the charging of two Electric Vehicles. The best day so far provided over 55 kWh with the average of about 47 kWh. Great System and Great Installer. I would highly recommend Ray Johnson and his crew for your Solar Installation.

Residential solar installation by Florida Solar One

Having made the decision to install solar on our new home in Fort Lauderdale, we went through an extensive due diligence process to determine what contractor to use for our project. We decided to go with Florida Solar One due to the companies' excellent credentials (fully certified engineers) and the full involvement of it's owner, Ray Johnson. We were not to be disappointed. After a thorough analysis (even involving drones) and feasibility study, Ray presented to us a step-by-step project plan with all detailed component specifications and pricing terms. The project was subsequently executed while we were on an extensive overseas trip. During the period, Ray kept us informed step by step via email about the progress of our project (permit, panel delivery and installation). He even sent us pictures of the installed panels. The project was executed exactly on the timeline as outlined and the project costs were exactly as budgeted. Moreover, Ray was involved from the beginning to the end and made sure that the work was performed to the highest standards (all panels lined up perfectly, even new cables running alongside the house have been nicely hidden). The system is working perfectly. We would highly recommend Ray for any new solar installation. He has outstanding credentials and takes extreme pride in his work.

Keys Life 2011 | 06/18/2018

Best Florida Keys Contractor Experience Ever

Our home was damaged by Hurricane Irma and when we put it all back together we wanted solar with battery storage so we would never be without power again. Our first call was to a company the company here in Marathon but, their customer service people proved hard to speak with and prices were out of our reach. Then we spoke with Ray with Florida Keys Solar One and sure glad we did. We had every kind of contractor there is working on our home and by far the guys at Solar One were the best of all. Highly recommended local company!

MASS | Marathon, FL | 04/09/2018

Solar GODS !

Ray and the Whole gang / + Jose did a great awesome professional job on our p[project only 2 months after a direct hit from IRMA !! She could not stop them. System runs great- Many neighbors and city inspectors all wowed by the quality and look of the array- not to mention it gets me 55-60++ KW a day with an eastern exposure ! which is all we had to work with. Check it out on cover of FKEC FEB magazine !!

Going green

Highly recommend this company. They completed our solar panel roof job timely and professionally. Savings they projected were on point! Looking forward to adding a solar carport with them too!

Great company to work with. Very professional and they did the work on time. I would recommend them to anyone looking to get solar at a great price.

Chad-Ad Distributors | 02/16/2016

Best Solar installer

My experience with Solar One and Ray Johnson was one of the most professional experiences i have ever had. Not only was it done on on time within budget but i am yet to find a local installer to find a flaw in my system. What makes it better is that after three years of my first install Ray has delivered on his original promiss. God bless Ray and Jamaica's Sunlight.

Florida Solar One Rocks you Like a Hurricane

Our company purchased a commercial property in Miami for our global headquarters that had a brand new TPO roof installed the year before. We wanted to put solar to keep our fixed operational costs low, predictable and enjoy tax credits. We received a rebate from the local utility but, internal delays from our growing company and choosing a solar contractor left us with only one short month to build the system else lose the rebate funds. It seemed mission impossible and we still had not hired a contractor. We accepted quotes and interviewed several companies but, Florida Solar One, clearly stood above the rest. The price was good and their commercial experience obvious but what impressed the most was their guarantee to navigate the Miami Dade Building Department, maintain our 25 year warrantee (on our brand new roof) and if they missed the mark would deduct the rebate from the cost of the project. With no risk we signed a contract and gave them full access. I am pleased to share the project was flawless. We received our final inspection with a week to spare. Florida Solar One even agreed to wait until FPL paid us before we paid them. The system has been operating for 8 months and it has outperformed all expectations. We expanded our operations and overall air conditioned space by over 30% and yet the cost of electricity is over $500/month lower than it was pre-construction. Going solar was a good, our savings has been great but, choosing Florida Solar One was the best decision we made. Go Solar with Florida Solar One and you will be glad you did!

Very Satisfied! Two Thumbs Up!

I had my solar system installed by Florida Solar One last year and I have absolutely nothing bad about the company or installation job. The installation was done professionally and the system has been delivering as promised. The staff was very friendly and extremely knowledgeable through the entire process. I shopped around with other companies, but I chose Florida Solar One based on their level of experience and knowledge. Due to the high level of technical work and investment, I did NOT want to chance this installation with any amateur solar contractors looking to build their experience at my expense. I talked to Ray a few times and I knew I was making the right choice going with Florida Solar One. Very friendly, fast, professional and knowledgeable. 5 stars all the way! Thank you so much!

JosephG | 01/07/2016

Fantastic Company

Everyone was incredibly knowledgeable and knew exactly what I wanted, what was best for me, and when I wanted it. Ray sure his stuff and my system has been working flawlessly since he installed it. It was cheaper than the competition, he sounded like he knew what he was doing, and my system was finished before I even noticed. They worked quickly, quietly, and were extremely polite. They did everything, all I had to do was write them a check! Very satisfied customer.

Thirtyseven10 | 12/12/2014

Professional service from start to finish

Since the day I met with the company's representatives I have been nothing but impressed. Excellent design team, quick turnaround on install, full support upon completion and the company has happily made any changes / modifications requested without batting an eyelid. I would recommend the company to anyone I meet... and I do.

James R. | 08/19/2014

I Highly Recommend Solar One!

On behalf of my partners and myself, I will like to thank Ray and the Solar One crew. Going solar was a smart decision for our business and choosing Solar One was an even better decision. The crew was very professional and completed the job 1 day before the estimated time of completion. It’s been a few months and the system is running smoothly without any problems. Looking forward to many years of generating electricity from the sun!

Rico | 08/19/2014

Solar One Great Install!!

Best result ever with a contractor, done on time as promised.

SW Ag & Hydro | 08/16/2014

Solar One

Our farm needs shade for our gardens and electric to power pumps. We asked FPL to provide power but it was very expensive. Solar One came up with a solution for both. We have an off grid system that will pay for itself in no time. Well done men!

Roger L. | 08/14/2014

Satisfied Customer

First of all, thank you once again gentlemen. I still find it fascinating how this technology works and having our 15kw system producing most of the electricity we use at our building is amazing. We received IRS tax credits, saving hundreds of dollars monthly and helping our planet, which is something our business has been focused on doing for the past few years. It was a pleasure working with Ray who is very passionate and knowledgeable when it comes to solar energy. I had a great experience and will recommend Solar One to everyone looking to install a solar energy system.

Vivian Marie | 08/13/2014

Very Professional Company

My best friend recommended Solar One to me after having her system installed by Ray and his crew. My husband and I are grateful to have chosen the right company for the job. The whole process from designing the system, getting the permits and installing the system went very smooth. Thanks guys!

Sharon C | 08/13/2014

Very Good Service

We hired Florida Solar One to install a system at our winter home in the keys. We are very happy with our choice. The system works great and we run our AC everyday now and have a battery back up in case of hurricanes. The system is great and the people are very nice.

LHPMom | 08/06/2014

Solar Solutions

I called not knowing what kind of system I needed to power my home and their team patiently sat on the phone with me talking through all of my options and possible tax credits. My husband called Ray and scheduled a site survey. Ray came out promptly and suggested a 4k system for our energy needs and we haven't looked back since. Thanks to Ray and his team for their patience and professionalism.

Donpedro305 | 08/06/2014

Great job

Very professional.. Finished the install on time.. Very helpful with completing the rebate forms for FPL..

Chad Ad | 08/04/2014

Very Happy Customer

Ray Johnson installed a system for me two years ago and I am glad he did. Solar is a new thing so I wanted proof of how it worked – not charts and slick brochures. He presented a no non-sense energy analysis with a turn-key price that was lower than almost all the others I spoke to. When done he showed me my working solar panels on his smart phone then programmed mine so I can watch now too! I can actually watch the energy being generated in real time. Very high tech and impressive

Chuck A | 08/04/2014

One Stop Shop

Great service. They helped me buy my equipment, get a permit and then installed the system. They did everything they said they would.

CA | 08/03/2014

Great Company

We hired Florida Solar One to install a system under the FP&L rebate after a bad experience with two other solar companies. They had the project approved for permitting in three days where the others wasted months. The installation team was clean, attentive and the system makes more power than promised. Highly rated!

Sun catcher | 03/17/2013

True Solar Professionals

It is our pleasure to write a review for Florida Solar One. As a globally recognized solar educational training college only the finest equipment installed by the most qualified professionals would do. Choosing Florida Solar One as our contractor was a perfect choice. They installed SolarEdge Inverters with Suniva panels which have proven to harvest more energy than we ever thought possible. We now enjoy thousands of dollars of free energy every month. The staff is made up of seasoned professionals who understood how to make the right material selections to build an amazing system that has already been proven to outlast Hurricane Sandy. It was great to have air conditioning and power when others had none. Best of all their prices were better than all other competitors and the systems were installed in one short week. Highly recommended!
