At FLS Solar Technologies our mission is to provide products that help make solar energy mainstream.
We are solar providers who create solutions for solar users. Our company consists of solar installers, solar engineers and solar designers. The products we make are designed by our own staff and our products are tried and tested in the field by our own installers.
We create solar solutions that make solar design, installation, monitoring and maintenance easier for the consumer.
Our flagship product is SunRex which is a Solar Thermal Monitoring device that can transmit data to our online app that provides real time production statistics.

With over a thousand installations completed, FLS Energy is committed to making solar mainstream. As one of the most experienced solar thermal design-build company in the U.S., we know firsthand the limitations of current solar thermal monitoring systems. That's why we are excited for FLS Solar Technologies to launch SunRex, a web-based solar thermal monitoring system that provides real-time, array level information (including temps, pressure, flow rates, glycol % and PH level) to accurately display and track energy production.
With SunRex you can monitor your system remotely, 24/7 from any web browser. Whether you have one panel or 1,000, SunRex helps you ensure system performance, capture energy production and monetize RECs – saving you money and time from day one.
