ABOUT SOLAR PLEXUS
A family-owned solar and renewable energy company built on trust, reliability, and community.
Our Story
HOW IT STARTED
Solar Plexus LLC began in downtown Missoula in 1994 as a small family-owned retail shop focused on renewable energy equipment.
​
Founded by Mary Hamilton and Lee Tavenner and joined by Rip Hamilton in 2000, the business grew through genuine care for customers, quality installations, and a commitment to help Montanans live more sustainably.
​
Over the years, Solar Plexus became not just a store — but a trusted guide for families, ranchers, and businesses transitioning to clean energy. Today, we continue our mission with the same values: honesty, craftsmanship, and a focus on long-term reliability.
The Founders — Mary & Lee
THE FOUNDERS
Mary and Lee laid the foundation for what Solar Plexus is today.
Their vision was simple: create a dependable, people-first company that brings renewable energy solutions to everyday Montanans.
​
With decades of hands-on experience, they became early pioneers of solar technology in the state — always prioritizing education, transparency, and building long-term relationships with customers.
