We know and love Solar and Texas

Howard "Scot" Arey
Howard "Scot" Arey

Solar CenTex was started by Howard "Scot" Arey. Scot was a career Army officer with much of his time spent here at Fort Hood. After he retired, he joined Nexolon America in San Antonio first as the Chief of Staff, then promoted to the Executive Vice President position. There he helped commence that company's efforts to manufacture high-quality/high-yield solar modules for San Antonio. Scot's commitment to solar in Texas is based on his conviction that Texas' growing population is outpacing its electrical generation capacity. He served on the Texas Solar Energy Society board of directors and was elected its Chairman through 2015. At TXSES, he was able to advocate for programs and policies to support solar in Texas. Scot has a B.S. from the U.S. Military Academy at West Point, a M.S. in Manufacturing from East Carolina University, an M.S. in National Security Policy from the U.S. Army War College and is a certified NABCEP PV Installation and PV Technical Sales Professional. He, his wife Jennifer and their girls live in Harker Heights.

Sabrina Arnold received her bachelor’s degree in Cellular Biology and Chemistry from the University of Mary Hardin-Baylor. She worked in Anatomical Pathology at Scott and White for 3 years prior to working with Solar Centex and has been with the company since April of 2016. Not only is Sabrina one of Solar Centex’s Sales Representatives, but she is also the Director of Sales & Marketing. “I’ve always wanted to help people and help save the world. Helping people go solar is my way to do both.”


Chris Walhgren keeps the trains on time and the ship running straight. Our office manager, she is the one that answers phone calls, coordinates permits, makes sure licenses, registrations, insurance, etc are kept up to date... she keeps Scot going in the right direction too. And she is married to Fred (See below)!

Our Install Team Leaders

Fred Wahlgren is the senior project manager and he is an Army Veteran/Retiree. He keeps the guys working in the right direction and ensure projects are done right. He is the craftsman and problem solver for many of our unique "nobody-has-done-this-before-with solar" projects. Fred has been with Solar CenTex from day 1 of it being in business.
