Helio Solar Power LLC

Helio Solar Power's mission is to create value for our customers by developing lasting relationships through transparency, ethical business practices, and affordable green energy solutions.

Some solar companies are cheaper than us. That's a fact. They may even offer the same panels and inverters. So what's the difference?

The difference is our approach and delivery. Most solar companies consider homeowners a number or statistic. "How many can they sell and install in a month?" We have an entirely different business model. Solar is a long-term investment and needs more than a quick install. We believe that creating a lasting partnership with our customers is imperative for the success of our company.

With over 10 years of experience, Helio Solar is more than a certified installer. We are a service provider that will continue to play an active role with our clients system management and maintenance even after installation.

We are solar experts. We educate, we provide solutions for our customers, and we provide the highest warranty in the industry. We are experienced roofers, electricians, general contractors, and engineers, all trained to provide lasting solutions for energy independence.

Don't settle for a lower number. Invest with a company who puts their clients needs first and is willing to work hard to earn their trust.

Highly recommended

My wife and I are confident that we’ve made the right choice. William has been a big help during the installation. Every time we needed help with something, it was easy for us to reach him through email or call. Besides, Helio's install crews were perfect! They quickly finished installing our panels just in time for our scheduled trip. Great service and their communication through the process was flawless. We already recommended them to our son.

Professional Service

This is my second home with solar panels. From the beginning I was impressed with Helio Solar compared to the other solar companies in St. Louis. The installation crew was very professional and respectful with regards to my property. From start to finish, the entire Helio team kept me informed. Thank you for a great job.

Outstanding Communication

Before Helio, I signed with another solar company. To say the least, it was a nightmare experience. My calls were never answered, I kept getting excuses, and I was tired of all the lies. A friend of mine went with Helio Solar two months after I signed with the previous company. Her system was already commissioned and I was still waiting on engineering. It left such a bad taste in my mouth that I was about to give up on solar entirely. My friend said she had a great experience, but I also think she just wanted the referral fee. Nevertheless, she talked me into speaking with one of the owners at Helio Solar. I am glad I did. It's crazy how open and honest communication made all the difference. I was assigned an account rep, Debra, and she was fantastic. She kept me abreast on every stage of the process. My system was installed within 3 weeks. The install crews were very professional and the final install looked great. We had severe rain and snow after they installed it. I forced my poor husband to climb into the attic and check to see if there was any leaks, dry as a bone. It's been 6 months since my system was commissioned. They still call every other month and check in on me. Great service.
