Anecdotal evidence suggests data friction costs are substantial. Harmonizing data would break additional barriers: • Increases access to capital by enabling automated risk assessment • Data clarity translates directly to business process scalability Soft costs are substantial Fig. 6 from U.S. Solar Photovoltaic System and Energy Storage Cost Benchmarks: Q1 2021, NREL/TP-7A40-80694, November 2021 Terms for GHI used by APIs offering irradiance data • G(h) • ghi (interval-beginning timestamp, unit of W/m2) • ghi (interval-end timestamp, unit of Wh/m2) • GHI • GHI (interval-beginning except at 1-minute resolution, then interval-ending) The OB Working Group (chaired by BluBanyan, Sunspec Alliance, Sandia) seeks to create an open data exchange standard for the distributed solar PV industry. A data exchange standard comprises: • A taxonomy • Tools to access reference data sets • A compliance test suite (future work) The Orange Button (OB) Initiative Vision: Harmonize solar data across the system life-cycle, from sales through operations What is a taxonomy? • “A taxonomy is… a semantic architecture - it is about naming things and making decisions about how to map different concepts and terms to a consistent structure.”1 • More than a dictionary or variable list because a taxonomy can provide hierarchical structure and can attach metadata to values • A taxonomy provides • Consistency (agreement on terms) • Connections (related terms can be grouped together into information objects), and • removes Ambiguity (terms can possess primitive data such as a timestamp and a unit) (credit to [1]). 1. https://www.earley.com/insights/why-taxonomy-critical-master-data-management-mdm • Open-source, public, free-to-use – JSON compliant with the OpenAPI 3.0 specification – Javascript style conventions – https://www.github.com/Open-Orange-Button/Orange-Button-Taxonomy.git • Editor at https://openobeditor.sunspec.org • Documentation at www.orangebutton.io (dated) Sender’s software uses OB terms to write data to a JSON file Receiver’s software uses OB terms to read data from a JSON file Taxonomy source code Data encoded to OB terms The Orange Button taxonomy The OB taxonomy provides common, reusable terms { “EnergyAC“: { “Decimals“: “1“, “EndTime“: “2020-02-08 09:59:59+07:00“, “StartTime“: “2020-02-08 09:00:00+07:00“, “Unit“: “kWh“, “Value“: 50.1 } } Examples of instance documents { “EnergyACArray“: [ { “Decimals“: “1“, “EndTime“: “2020-02-08 09:59:59+07:00“, “StartTime“: “2020-02-08 09:00:00+07:00“, “Unit“: “kWh“, “Value“: 50.1 } ] } Editor demonstration – PVSystem object Demo of AHJRegistry https://ahjregistry.sunspec.org/ Kimpton Monaco 15 W 200 S, Salt Lake City, UT 84101 Blu Banyan built - the award-winning fully-integrated business application for the solar industry, eliminating the biggest challenge of disparate and disconnected systems.
