About the SunSpec Alliance

The SunSpec Alliance is a California-based non-profit trade alliance that unites over 180 leading companies from around the world to advance standards for Distributed Energy Resource (DER) interoperability, cybersecurity, and grid resiliency. Our members include solar, energy storage, electric vehicle (EV), EV charging, software, and service providers from North America, Europe, Asia, Australia, and the Middle East.

SunSpec standards streamline the integration and operation of residential, commercial, and utility-scale DER systems across the smart grid. These standards reduce cost, foster innovation, and accelerate the transition to a clean and secure energy future.

From foundational interoperability standards like SunSpec Modbus and IEEE 2030.5/CSIP profiles to cutting-edge cybersecurity frameworks and certification programs, SunSpec provides the tools the industry needs to ensure compliance, reliability, and market scalability.

SunSpec members actively shape the technical agenda and collaborate in working groups that produce specifications, test procedures, and certification pathways.
