Nice Job!

I started my process earlier this year and originally met with Marlis. I have an older home in which she was very knowledgeable about the electrical needs. Because Marlis was educational and upfront, there were NO hidden costs. I appreciate their process and transparency. Any one that I would speak to at the company was always upbeat and professional. Great Job!

Awesome Team!

I have had my system a little over six months now and could not be happier. Everything that Cameron had discussed with us was done perfectly along the way. He certainly took the time to educate me and my wife on the process and product. CellSun is Local, Honest and Prompt!

Wow!

There are not many solar companies out there that will provide you with Marlis and her team at CellSun will. Not only was Marlis exceptional at answering all of our questions, the install team was so nice and professional. You will be very happy with your project from this company!

Excellent Team

I had the pleasure of being able to see a few installations happen in my HOA as my home was being built. Happy to have been referred by my community to meet with CellSun and Cameron for my solar needs. They did a fantastic job, fast and very neat!

High Quality Installation!

I had the pleasure of working with Marlis and the rest of the CellSun solar team and cant tell enough people to take the time to meet with Marlis! The education and understanding that she provided us with for our solar project was unlike any other company. Strongly recommend this company for your solar project!

Great overall!

Not your typical review, but I actually chose to go with another company initially and made a mistake! I came back to work with Marlis after being led to believe something that was not. The reason I came back to CellSun was their commitment to be the best and they did that. I needed an install before the end of year for tax purposes and they made it happen! I would not always trust what you read or hear, do yourself a favor and save time and meet with the team at CellSun!
