XBRL US, in partnership with the SunSpec Alliance and the solar industry have developed a draft taxonomy for solar financing called the Orange Button Taxonomy. This taxonomy is available for review and comment until March 12, 2018.

Participate in the Orange Button Taxonomy Public Review


The U.S solar industry has grown by an average of 68% per year for the past decade (Source: SEIA). Rapid expansion in the solar energy industry highlights the need to streamline the collection, management and exchange of solar datasets to reduce market inefficiencies and lower costs for consumers.

Taxonomy Review Software Sponsor

Orange Button, which is a U.S. Department of Energy Solar Energy Technologies Office-funded program, was launched to set data standards for the solar industry. The initiative seeks to make solar energy cost-competitive with other forms of electricity by funding cooperative research, development, demonstration, and deployment projects by private companies, universities, state and local governments, nonprofit organizations, and national laboratories to drive down the cost of solar electricity to $0.06 per kilowatt-hour.

The XBRL data standard is uniquely suited to transport financial datasets that are needed to communicate distributed solar financial disclosures. As part of the SunSpec Alliance project team, XBRL US leads a working group to build out financial terms for the solar energy taxonomy, leveraging elements from the U.S. GAAP Taxonomy and from existing data standards in the solar industry.
