Simplifying the Exchange of Solar Project Data

Orange Button Data Standard

Orange Button logo

Collecting and reporting project data contributes up to 30% of solar project costs, making data exchange more expensive than solar hardware.

With funding from the U.S. Department of Energy, SunSpec Alliance joined with Smart Electric Power Alliance, National Renewable Energy Laboratory, kWh Analytics, Solar Energy Industries Association, and more than 500 industry practitioners to simplify the exchange of solar project data using the Orange Button data standard.

Orange Button is an open data exchange standard for the distributed solar PV industry. Comprised of information models, a standard taxonomy, a standard Application Program Interface (API), and supporting compliance test suites, Orange Button enables the free flow of data between information systems used in the solar asset lifecycle to decrease long term costs and increase innovation.

Market Benefits of the Orange Button Data Standard

Drive Down Soft Costs for Residential, Commercial, and Utility Projects

Accessible Project Data

Data standards enable investors, project developers, and asset managers to instantly share data without time consuming manual data entry and validation.

Lower Project Costs

A standardized solar data format significantly lowers the cost of capital by reducing process inefficiency throughout the project development and operational lifecycle.

Extensible for New Technologies

Stakeholders can add data fields to extend Orange Button, incorporating energy storage and other distributed energy resources.
