Strata History & Culture

Pioneering an Industry, Building a Reputation for Excellence

Founded in 2008 in Chapel Hill, North Carolina by Markus and Cathy Wilhelm, Strata Solar first focused on the residential solar thermal market, later moving into commercial rooftop PV, before becoming a leader in full-scale utility solar projects.


Strata’s unique, scalable approach made it easy for multiple projects in a region to be completed in a short amount of time, quickly elevating North Carolina to #2 in the country for installed solar capacity. Regularly ranked among the industry’s leading solar companies, Strata is consistently recognized for its commitment to quality, safety and for simply making solar work.

Our experience working directly with utilities and local communities gives our customers the confidence they seek when choosing a solar partner.

Raising the Bar

After widespread success in its home state of North Carolina, Strata Solar has expanded into new markets, bringing the experience of developing and building more utility-scale solar farms than anyone in the industry.

Strata takes a leadership role working with the policy makers who are advancing opportunities for more clean energy in local regions. By working directly with legislators and regulators to create opportunities for solar to compete in energy markets, we are driving a cleaner energy mix and stabilizing energy rates, all while saving electricity customers money. We are proud of our reputation for finding collaborative solutions and making it work for all parties.

Strata has become known for its long-term thinking and actionable strategies. Our ‘First Time Right’ training program is a corporate mindset that transcends all divisions within Strata. We've learned valuable lessons from leading the success of solar in North Carolina, and as we scale, we're implementing a total quality management program for guaranteed continued success.

The success of Strata comes completely from its people, who share a passion for bringing more solar to more communities and reducing our reliance on less sustainable energy sources.
