Sites & Data
The V2 API consists of three building blocks that build on each other. You configure a site once and then query it for forecasts and historical data.
The three building blocks
Sites & Strings
A site describes your PV system: coordinates, one or more PV strings (orientation, tilt, power) and optional configuration (module technology, shading, inverter, tracker). Elevation, timezone and horizon shading are determined automatically.
Forecasts
A PV power forecast for a site — by default just the power (pv_power),
optionally with weather, irradiance, clear-sky reference, per-string values and a
variability band.
Historical Data
Past PV yields and weather data over freely selectable time ranges — as a rolling window
(period) or with a fixed start/end date.
You'll find the complete endpoint, parameter and field reference in the API Reference.
Authentication
All V2 endpoints use bearer token authentication:
