Anyone operating a PV system wants to know what it will generate tomorrow. pvnode gives that answer — precise, at 15-minute resolution, available worldwide.

The forecast engine runs deep physical models: module technologies, spectral effects, horizon and row shading, snow behaviour, inverter clipping, and more. Not as a premium feature — included in every plan by default.

Developers integrate the REST API directly into their applications. Those without coding experience use pvnode Studio: configure a system visually, export data as CSV, XLSX, or JSON. Already integrated into SOLECTRUS, EVCC, and ioBroker.

The optional Nowcasting add-on recalculates the forecast every 10 minutes using live satellite data — for applications where real-time accuracy matters.
