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 Gh 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 0959590700“, “StartTime“ “2020-02-08 0900000700“, “Unit“ “kWh“, “Value“ 50.1 } } Examples of instance documents { “EnergyACArray“ [ { “Decimals“ “1“, “EndTime“ “2020-02-08 0959590700“, “StartTime“ “2020-02-08 0900000700“, “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.
