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:

TerminalCode
Authorization: Bearer YOUR_API_KEY
