pvnode is a photovoltaic data API. Each endpoint accepts a set of system parameters and returns modeled PV data — as a time series, aggregated values, or a full system simulation, depending on the endpoint.

A basic request only requires location, slope, and orientation. The API also supports more detailed configurations: horizon profiles, row shading, tracker systems, module technology (PERC, TOPCon, CdTe), temperature coefficients, albedo, cable losses, and more. All parameters are optional beyond the basics — add them when precision matters.

All endpoints follow the same pattern: a single GET request with query parameters, a JSON response. No SDKs required, no setup beyond an API key.
