Our Mission

Our mission is simple: help homeowners make informed decisions about solar by providing honest recommendations, quality installations, and exceptional customer support.

We believe education creates confidence. When homeowners understand their options, they can choose the solution that best fits their property, budget, and long-term energy goals.

Christopher Gersch founded RxSun in 2018 to bring the same expertise, integrity, and innovation that had fueled his commercial energy companies to homeowners across the Midwest. As one of the energy-focused companies within the Altimus Capital family, RxSun was created to make residential solar more accessible, affordable, and transparent for families looking to take control of their energy future.

Having come from humble beginnings himself, Chris has always believed that every homeowner deserves the opportunity to lower energy costs while making a long-term investment in their home. That vision has driven RxSun’s growth into one of the nation’s fastest-growing residential solar companies, earning recognition on the Inc. 5000 list for multiple consecutive years.

Today, RxSun continues to help homeowners achieve energy independence while reflecting the values that unite every company within the Altimus Capital family: innovation, trust, and creating a lasting positive impact.

Feeding America

Powering Homes.
Feeding Families.

At RxSun, we believe every solar installation should create an impact beyond clean energy. That’s why we’ve partnered with Feeding America® to donate 1,000 meals for every residential solar system we install. Together with our homeowners, we’re helping provide meals to individuals and families facing food insecurity while investing in a cleaner, more sustainable future.

When you choose RxSun, you’re doing more than lowering your energy bills and reducing your carbon footprint—you become part of a mission that strengthens communities. Every completed project helps support Feeding America’s nationwide network of food banks, allowing your investment in solar to make a meaningful difference both at home and across the country.

One solar project. 1,000 meals. A lasting impact.
