Incredible experience with this business. They handled basically everything for me and answered every question I had without a problem. Everything was explained fully and I truly believe the whole experience could not have gone any better. Not to mention the absurd amount of money I saved a month by switching to solar! Thank you SunMark for everything you have done for me!

Mark was awesome! I knew nothing about solar (just knew my electric bill was too high and needed to do something about it) and mark was patient and answered all of my questions in a way i could understand. He even removed trees in my yard so i could get more sun to the panels. My electric bill doesn’t pain me to look at anymore lol. If ur looking for solar, SunMark is definitely the way to go. A decision like this is much easier when you are dealing with someone who truly knows what they’re doing

The team at SunMark Solar did a fantastic job. They are very thorough and explain the process step by step. Even after the panels were installed and we had some issues getting the service turned on … they stepped right in to resolve the issue. Customer Service with them is top notch and would recommend them for your solar panel needs

I couldn't be more satisfied with the service I received from Sunmark Solar. From start to finish, the entire process was smooth and hassle-free. The installation was quick, easy, and the final result looks fantastic.
Not only did they install the solar panels, but they also went above and beyond by replacing my roof and removing two trees that were in the way—all for a great price. Their team was professional, efficient, and made sure everything was done to the highest standard.
I highly recommend Sunmark Solar to anyone considering going solar. Their attention to detail and commitment to customer satisfaction is truly impressive.
