They did all the work to complete with Permission to Operate
Kokosing Solar designed my system. They did all the paperwork with the electrical utilities company. They made sure once the install was completed that it was inspected. The electrical company gave me permission to operate an export, my extra solar generated power to the electrical grid. I am very happy with the end result. They are professional and have done very good work.

Kokosing Solar (Athens) is amazing. They have wonderful customer support (thank you Christina ) whether you call or email them they always are polite and get back with you right away. Their attention to detail is impeccable. Eric, their head technician, came out to service our Solar Edge inverter/safety switch because the fuses kept blowing. He was very thorough, knowledgeable and found that the fuse box did have some loose connections, and some wires in the inverter box were hooked up wrong from a previous installer. He was also able to get our solar edge app up and running and transfer the past owners into our name. We now see a blue and green light that means we are producing solar and it’s communicating with our Wi-Fi app. We are still learning about solar and how it works. When we purchased our home recently, we acquired the solar panels, so it’s definitely been a learning process. Kokosing Solar, knows a lot about our system “Solar Edge” so we will definitely be using them for as long as we have our solar panels. Thanks again, Kokosing Solar for getting our inverter up and running again.

After Installation Service is terrible
We had a 30 panel system installed by Third Sun. They did a good job and the system has worked well. Last year one of the panels went bad and we contacted them about the warranty. The panels are from LG. . We were told when we contracted with Third Sun that if there was a warranty issue, we could go through them. When I reminded them of this they said they would look into it only to send an email a few days later saying they could not get in touch with LG. They basically said that it was our responsibility to contact LG but would not even supply any information about how to do that. The next issue has come up recently. When we purchased the panels we specifically asked what the cost would be for them to remove and replace the panels if we had to have the roof replaced. They told us that is would cost around $4,000. We are now having that done, so I contacted them and the price they now give me for removing and replacing the panels is over $19,000. Even given inflation this is outrageous. After the government tax rebates that is only a few thousand less than the original cost of the whole project and I suspect that we could put an entirely new system in for not much more than that. The message is beware of this new incarnation of Third Sun. Whatever integrity the original company had is apparently gone, so do not expect any help or service from them after installation. We are not only committed to solar but also in another area of the solar business, so we are well informed about costs. Kokosing is not a company with which we would advise doing business.
Response from Kokosing Solar (Previously Third Sun Solar)
Thank you for taking the time to share your experience. We sincerely apologize for any inconvenience and frustration you've encountered regarding the warranty process for your solar panel and service inquiry. First, we want to clarify the situation regarding LG. While LG has stopped production of solar panels, they continue to manufacture solar batteries, which is why they are still listed on our website. LG no longer makes solar panels, and the information we received from LG was that we can get the homeowner a few hundred dollars to replace the panel. In August of 2023, the quote was declined by the customer, until he needed further service work done. Regarding your concerns about the cost of removing and replacing your panels during a roof replacement, we understand your disappointment with the service cost. After a review of our files, we were not able to find the quote for $4,000 deinstallation and reinstallation. Even back in 2016, $4,000 for this scope of work would have been too low to cover our costs given the site complexities. Since your initial installation in 2016, the industry has seen significant changes in labor rates, operational costs, and material costs. While we acknowledge your disappointment with the pricing, we assure you that our aim is not to overcharge but to cover our operational expenses and maintain the quality of our services. As a fellow participant in the solar industry, we understand the importance of trust, honesty, and fair pricing. As the company has transitioned from Third Sun Solar to Kokosing Solar, rest assured that the majority of the solar team and leadership team have remained the same. The commitment to our integrity and commitment to our clients is unwavering and has only been bolstered by the transition into the Kokosing group of companies. We value your feedback and will use it to improve our services moving forward. Once again, we apologize for any frustration or inconvenience you've experienced. Please feel free to reach out to us directly at solar@kokosing.biz if you would like to further discuss your concerns or if there's anything else we can assist you with.

Kokosing is fantastic to work with!
It was great working with EVERY person at Kokosing. Everyone was easy to work with, knowledgeable, and responsive! The installers/electricians are experienced. They knew exactly what to do and made everything look great. The salesman (John Miller) presented and explained options, which none of the other solar companies mentioned to me (unless I asked them). John quoted microinverters, while more expensive, were better for my L-shaped layout. Also, Kokosing was unique in proactively quoting 405w panels, which means a more compact design (less roof area needed).

Up and Running!
Very transparent process from start to install. Forthright, friendly and responsive to any and all questions or inquiries during sales, planning and installation. No hard sale re: sale of system. Installers were cordial, efficient and timely. System went on line a week ago. The monitoring capability via "Enlighten" is a great tool.

My family and I had a great experience from beginning to end with Third Sun Kokosing Solar. The crew were friendly, professional and very helpful. During our first full month of operations (a sunny September 2022), our AEP electric bill was cut in half. Since the weather has turned more cloudy and rainy, we're still producing about 25 to 35% of our electric every month. The battery backup up also covers us partly into the night. I am very happy with out new solar system.

Awesome company...lives up to their word and delivers quality. Just had my system installed earlier this week. The crew was professional, clean, and did a GREAT JOB! The project manager has kept me well informed and the process from start to power on has been very smooth and much easier than I had expected. Third Sun took care of the coordination with the power company setting up Net Metering and I am now putting energy on the GRID. I am even impressed with power generation on cloudy days, with production above my consumption (it is fall, so the A/C isn't running, but the days are also shorter and the sun is lower). The application to monitor the system is VERY easy to use and I marvel at watching the dashboard on my laptop as I am able to monitor how much power I am consuming, how much power I am pulling from the grid, how much power I am producing, and how much NET power I am putting back on the grid, making my meter run backwards. THANK YOU Third Sun Solar.

Knowledgeable, professional, and communicative. I'm really happy with their work and glad I went with Third Sun even though they were a little more expensive than my other option. Worth it for their expertise. I know the transition to Kokosing was bumpy internally but from the outside it did not affect me much at all, and that was impressive in its own right. I will be recommending them to everyone I know who is interested in solar.

Solar power in the not-always-sunny midwest.
Third Sun solar installed our system in August of 2020. We contacted several Ohio-based companies and they were all quick to respond and offer a proposal. We chose Third Sun based on their established track record. It has been a very positive experience and the results exceeded projections. Currently, we are offsetting 100% of our electrical needs with the solar system. This, in Dayton, Ohio which is not the sunniest place in the world. Go Solar!

We chose Third Sun Solar after meeting with 2 other companies. We are very happy to say we made the right choice. They were the most knowledgeable, thorough, professional, and service oriented. Jake, Gordon, and team worked through rain and a blizzard to complete our amazing installation. Ernie and Christine proactively communicated all permitting and designs from start to finish. Installation, inspection, meter swap, and power generation were completed within only a few weeks. Highly recommended!

Love our new solar array from Third Sun
It's been a dream of mine for over twelve years to have a solar array on my home. It's come true! The wife gets oak flooring and I got solar panels from the sale of our old home. I was a little quicker to act, but yours truly will be doing the flooring. From start to finish the process was perfect. I especially liked the salesperson's candid explanation that the other company was quoting too large an array for Janet's and my needs. Our 10 kW array will almost offset our use and the gap can be made up with better energy efficiency measures. I improved the efficiency of it over 60%. Our new home is much better, so every percent will be a challenge. Thanks Third Sun for making it fun to go Green!

Great commercial installation
Great people, great customer service, and great installation. Third Sun was very helpful from the design and plan stages, to helping us apply for and get a REAP grant, to installation. Since the installation, the system just runs on its own and generates money-saving electricity. We hardly even notice it’s there, other than looking great on our roof.

Easy as a Sunny Day!
From the beginnning of our "dream" of going solar, Third Sun provided great information, and patiently worked with us to complete the instatallation. The owners are actively involved in promoting solar locally and regionally. and they truly live their philosophy. Their off-the-grid home has been on numerous tours, and they are active in helping everyone share in this mission to lessen our carbon footprint. The installation was fast and efficient, and all of the workers were friendly and patient, even with a pesky, inquisitive homeowner. Having waited and planned for this over many years, the installation was a perfect culmination of the "dream".

Super pleased!
Working through the Columbus Solar Initiative, we were fortunate to link with Third Sun Solar. The initial look at our home was completed by a most courteous and pleasant young man who answered a lot more questions we had thought about since signing up. The installation crew was there on time, actually early, set up and completed the work in one and a half days. Everything was absolutely cleaned up from the ground and nothing around the house was disturbed. We are grateful and pleased with everyone we worked with through the process, even the billing was pleasant. Cannot say enough good things about this crew. And the system is working beautifully.

All our contacts with Third Sun have been positive. From introduction and inquiry to assessments to estimates (technical and financial), to appointments to installation, Third Sun has been clear in communication, thorough in explanation, and responsive to questions. Installation schedules were clear well in advance (with notice that there is a significant weather-dependency factor), and the installation itself (in mid January) took a day and a half (we did have a fairly simple layout to deal with); they arrive late morning on a Monday, on Wednesday morning the system went into operation after a city inspection. There have been no problems - zero - in the six months since. All our calls to them, through the entire process to the present, have been returned quickly and all questions answered completely. Great people to work with, and a great product. Also, it's fun to monitor the system online.

I contacted several solar companies and was extremely pleased with the response from Third Sun Solar. From initial contact through installation I could not have been more pleased. I worked 38 years in the utility business and have rarely had as good of an experience with a vendor as I have with Third Sun Solar. If you are considering a solar installer you need to at least call TSS.

We are very pleased by the quality of work and product line. Third Sun also re-worked their schedule a little to make sure all work was completed before 12/31/2016, so that we could apply for the tax credits available for 2016. The electrician took pride in his work inside the house too...the work is clean and looks professional.

We cannot say enough about Third Sun, The communication from start to finish was exceptional. All our questions and concerns were answered in a timely manner. We had some zoning hurdles to overcome and Third Sun helped supply info to get through the process. They came to the site visit and to the install day on the agreed time. The installation was very clean and professionally done, even the county inspectors that came for the final inspection said it was one of the best looking installs they had seen. We would highly recommend Third Sun to anyone looking to go solar.

My first house
Buying my first home was stressful enough and from the start we planned on going solar. Third Sun did a great job of making sure that stress wasn't part of the that process. The 10kw system that we installed was another large investment but we couldn't be more pleased with the process . From start to finish the level of professionalism was spot on. Our home is all electric and we knew it would be an energy monster. From that first day the system was switched on it has helped us tame that beast. The system was insalled in Oct. and we have watched our bill drop each month with May and June at $0 and July $2.15. To say that we are happy is an understatement. Thank you Third Sun.

One year system recap
I was very pleased with the one year recap of my system. It was estimated at @ 79% and came in at 81% of electric usage covered. My electric out-of-pocket costs were reduced 80%, included in this figure, 8% came from carbon credits. Installation went the smoothest in the entire process and concerns were dealt with promptly. I would recommend to others looking to install a solar system that it is important to get very accurate historical information pertaining to your electric usage when in the costing/design stage.
