Using modules donated by Freedom Solar, Hays Energy Services worked with me to build this beautiful 5kW system for David Power and family in, Katy, Texas, at a greatly reduced cost. Mr.Power and family will see a rapid return on investment with greatly reduced energy bills this summer!

Testimonials

a year ago
Clay McKelvy designed, built, and installed an off-grid solar system for us in a remote and rugged part of the Texas Panhandle canyon country a few years ago. It was no easy task, and he did it on his own, flawlessly. The luxury of electricity is sometimes taken for granted until we experience life without it. Because of Clay’s designs and hard work, our small campsite building in the canyon country was transformed overnight into a comfortable treasured get-away that we can now visit year round. Clay is strikingly smart, genius really, with everything related to science and technology, but his genius mind is not the only reason he is the best at what he does. He is a true artist, and he brings an artist's heart to his work, always. He is a perfectionist, and he is the hardest worker anyone will ever meet. My husband and I are forever grateful for his fantastic creation. Thanks for everything Clay!
