Job description

About Buffalo Solar

At Buffalo Solar, our mission is bold and crystal clear, power 1,000 businesses with clean, reliable solar energy by 2035.

We specialize in commercial and industrial rooftop solar solutions that help companies cut operating costs, lock in predictable energy expenses, and meet long-term sustainability goals. Every project we deliver is designed to perform as a true business asset, driving savings, stability, and growth for decades to come.

Founded in Buffalo, NY, Buffalo Solar was built from the ground up by Founder and CEO, Tyler Uebelhoer. With more than a decade of experience as an electrician and construction professional, Tyler recognized solar as the industry where he could make the biggest impact, not just for businesses, but for the economy and communities of Western New York. What started in his South Buffalo living room in 2015 has evolved into a modern solar development and EPC company serving organizations across New York, Pennsylvania, Massachusetts, Connecticut, New Jersey, and beyond.

Over the past 10 years, Buffalo Solar has grown from a local startup into a trusted regional partner, yet our approach remains hands-on and personal. From the first consultation through post-installation support, we stay closely connected to every client to ensure their system is reliable, efficient, and built for long-term value.

We care so deeply about the businesses we serve that we developed our own in-house 15‑Year Peace of Mind Warranty, providing unmatched protection that separates us from the rest of the industry.

Our vision is ambitious but simple, 1,000 businesses powered by Buffalo Solar by 2035. We have already come a long way from our beginnings in Western New York, and we are just getting started.

Buffalo Solar is a growing commercial solar and energy company serving businesses throughout New York and the surrounding region. As our commercial project volume continues to grow, we’re expanding our team and preparing for our move into the new Center for Energy Empowerment in Alden, NY.
