aid: solcast name: Solcast description: >- Solcast is a solar and renewable energy data company, acquired by DNV in 2023, that provides high-resolution, satellite-derived solar irradiance, PV power, weather forecasting, and historical climate data via a developer API. Its data covers live, forecast, historical, and typical meteorological year (TMY) datasets for rooftop PV, advanced PV, grid aggregations, and soiling models globally. type: Index position: Consumer access: 3rd-Party image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - Solar - Energy - Forecasting - Irradiance - Weather - Renewable Energy - PV Power created: '2025-05-02' modified: '2026-05-02' url: >- https://raw.githubusercontent.com/api-evangelist/solcast/refs/heads/main/apis.yml specificationVersion: '0.19' apis: - aid: solcast:solcast name: Solcast API description: >- The Solcast API provides live, forecast, historical, and typical meteorological year (TMY) solar irradiance, PV power, and weather data derived from a global fleet of weather satellites. It supports rooftop PV power, advanced PV power (for registered sites), grid aggregation data, and soiling loss models (Kimber and HSU). Authentication uses an API key. Data is available in JSON and CSV formats with 5- to 60-minute granularity anywhere on the planet. humanURL: https://docs.solcast.com.au/ baseURL: https://api.solcast.com.au tags: - Solar - Forecasting -
