Sensor data

Sites can have sensors attached to them that report measurement data. Today, this API exposes readings from irradiance sensors (units: W/m²), typically installed alongside a rooftop PV system.

Typical use cases

• Compare measured irradiance against a PV resource's actual output to estimate what production should have been during a curtailment window.
• Feed irradiance time series into your own PV performance models or billing calculations.
• Cross-check forecasting accuracy against measured ground-truth conditions.

What the API does not do

• No aggregation. Only raw readings are returned. Hourly, daily or monthly rollups are for the client to compute (for example with pandas resample).
• No server-side gap filling. Intervals with no reading are omitted from the response. If you need a regular time grid, reindex client side.
• No CSV or bulk export. JSON over HTTP only.

Getting started

• Reading sensor data walks through the endpoint, parameters, and pagination pattern with a pandas example.
