Ryan Holtz

Owner & Off-Grid Specialist

Ryan graduated from West Point with a degree in Mechanical Engineering.

Ryan got started by studying with Solar Energy International and the Solar Living Institute. He loves developing and sharing solar technology. Ryan has taught solar energy classes at Coconino Community College, Willow Bend Environmental Center and all around Arizona. Some of Ryan’s favorite moments in solar work are watching a solar customer’s meter spin backward for the first time, and providing solar power to Navajo and Hopi families living off-grid who have never had electricity in their homes.

One of Ryan’s main goals is to make solar energy accessible to everyone by offering solar options that are affordable and easy to use. He acknowledges there are some hurdles to widespread solar energy use, but believes that with a little ingenuity like the Plug and Play Solar Kits, it will soon become a normal part of everyone’s daily life.

In his free time, Ryan is often outdoors. He enjoys mountain biking, running, disc golf, hiking and camping.  His favorite thing to do is sit around a campfire with his wife, Carolyn, and their dog Tully.

Jim Corning

Founder

Jim Corning’s professional life revolves around aviation, energy, and engineering. He was a student at MIT in the 1970s, and saw firsthand how the oil shortages of the ‘70s plunged our country into a place of scarcity. Since then, he has worked in the oil industry on the Arctic coast, built electric motorcycles, organized sustainable living fairs, taught classes on solar electric systems, and helped Ryan Holtz start up Prometheus Renewables. Jim’s goal is to help Americans find a way to energy abundance, and it gives him great pleasure to see Prometheus’ clients harvesting their own clean solar power, right at home.

When Jim charges his Chevy Volt with solar power, he enjoys the abundance of driving on sunshine. It’s very liberating.

When he’s not working, Jim loves hiking, mountain biking, flying and backpacking around the beautiful mountain west with his wife Holly.
