What We Do

Utility Companies

More than just developing a solar program, we’re a true partner to utilities and are fully engaged from time of launch throughout the entire customer experience.

Community Solar

We develop unique community solar programs that are cost effective and beneficial to both the utility and community.

Marketing Collaboration

We partner directly with the utility to execute programs that raise awareness within the community on the many benefits of adopting solar.


Our solar customer portal, which can be whitelabeled, easily integrates with the utility, automating solar credits directly to the customer.

Customer Service

We serve as the customer service front line to all community solar customers, relieving the utility from any increase in customer service inquiry load.

Our Work

Our mission is to make solar accessible to everyone and we do this with our innovative technology and ‘thinking outside the box’ programs.

3 Party Power Purchase Agreement with Client and Utility

Vitesco Technologies selected Big Sun Solar to build a large-scale solar project adjacent to their manufacturing facility in Seguin, Texas. Local utility, Guadalupe Valley Electric Cooperative (GVEC), approved a 3-party power purchase agreement (PPA) with Big Sun and Vitesco to help Vitesco reach their renewable energy goals. Through this agreement, Big Sun Solar will own and operate the solar project, and Vitesco will purchase the electricity generated to offset their energy consumption. 

Project Facts

  • The 2.6MWdc project will generate roughly 4,800 megawatt hours per year through 4,800 solarpanels meeting about 13 percent of Vitesco Technologies’ annual energy consumption at the Seguin facility.
