"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"Art and his team were incredibly responsive, punctual, and did great work. Also, their price was about 50% lower than competitors. I'm no engineer, but their system to approaching foundations seems quite innovative. Our floor feels much harder as a result."

"Working with Mr. Guillen to design my bathroom was an incredible experience from start to finish. He listened carefully to my ideas and then elevated them beyond anything I could have imagined. What I ended up with is a spa-like retreat right in my own home ? calming, elegant, and thoughtfully designed. He paid close attention to both style and function, recommending clever storage solutions without sacrificing the clean, minimalist look I wanted. The tile choices, lighting, and fixtures he suggested came together beautifully, and I constantly get compliments from guests. His professionalism, punctuality, and genuine passion for what he does made the entire process easy and enjoyable. I never felt overwhelmed or out of the loop. I highly recommend him to anyone looking to transform their bathroom into something truly special."
