Investors, developers, software providers are encouraged to participate

September 12, 2017, SAN JOSE, Calif. — SunSpec Alliance and XBRL US announced today the launch of a 30-day public review period for the initial draft of Orange Button data standards for solar financing. The digital dictionary of terms, called a taxonomy, was developed as part of the U.S. Department of Energy SunShot Initiative’s Orange Button SM program that aims to make it easier to aggregate and share solar data, facilitating more efficient and cost-effective financing of distributed energy projects.  SunSpec Alliance heads the Orange Button project team that is tasked with establishing an open, easy-to-adopt, solar data architecture, and standards.

“Standardizing data collection is a critical means to reduce the soft costs of solar financing,” said Tom Tansy, Chairman of SunSpec Alliance, “All solar energy stakeholders owe it to themselves and their businesses to review the standards and give us feedback. Every participant has a chance to influence the final standards that will be the industry norm in solar financing. That will benefit participants’ companies, and ultimately, the entire industry.”

The XBRL data standard was chosen for Orange Button because it is a free, open, global standard, uniquely suited to financial data. XBRL US is a nonprofit standards developer that built XBRL data standards for public companies, mutual funds, and credit rating agencies, under contract with the U.S. Securities and Exchange Commission. XBRL US leads the effort to build the financial portion of Orange Button standards, leveraging elements from the U.S. GAAP Taxonomy for public companies, and from existing solar data standards.  

Public companies in the solar industry, such as electric utilities, investors, and solar developers, already format their financials in XBRL which will ease the path to Orange Button adoption. The value of standards increases as more companies use them.  A growing number of companies and applications are adopting, implementing, and facilitating this initiative, such as Sunnova Energy Corporation and Wells Fargo, among others. In Oracle’s Enterprise Performance Reporting Cloud Service, the Disclosure Management capability enables the creation of XBRL files based on the Orange Button taxonomy.

“XBRL is the ideal standard for Orange Button given the need for consistent, comparable financial information in solar financing,” said Campbell Pryde, President and CEO, XBRL US, “XBRL US, along with SunSpec, has a strong interest in the success of Orange Button, and we look forward to continuing to develop, refine and expand on the taxonomy to cover more use cases, and to continue to meet the needs of the industry as they evolve.”

Orange Button standards represent the life cycle phases of solar financing, including feasibility, design, construction, finance and operations. Content available during the public review includes the digital dictionary of data fields and definitions, which can be easily viewed, and commented on, through a review tool called Yeti, contributed to the Orange Button program by CoreFiling, a global supplier of XBRL-enabled financial reporting software.
