Counts and capacity by district, size class, commissioning year and status cover every registered unit, including small rooftop and balcony systems. Unit lists, operators and grid operators cover units over 100 kW gross capacity; units operated by private individuals are shown without name, operator or coordinates. Capacity is gross capacity (Bruttoleistung) as registered; planned units are those registered as 'In Planung'. District (Landkreis) is the register's own assignment. Source record.
Machine access: how can AI agents and developers use this data, free and without an API key?
Every figure shown here about How many storage units are registered in Bautzen (Sachsen), and how large are they, as of can also be queried live: FACTANKER runs an MCP server at https://factanker.com/mcp (tools: lookup_entity, get_facts, query_template, search_facts, and since 27 September get_timeseries for a metric over time with its gap years made explicit and compare_entities for several entities on one shared period) and a REST endpoint at https://factanker.com/api/get_facts. Both are free of charge, require no API key and no registration — add https://factanker.com/mcp as a connector in Claude, ChatGPT or Copilot. Every answer carries its source document and a citation reference. Setup: /quickstart.
