Historic Data API

Historical irradiance, weather and power data, from 2007 to 7 days ago at 1-2 km and 5 minutes resolution.

---

The module HistoricClient has the following available methods:

Endpoint	Purpose	API Docs
GetRadiationAndWeather	Get historical irradiance and weather estimated actuals for up to 31 days of data at a time for a requested location, derived from satellite (clouds and irradiance over non-polar continental areas) and numerical weather models (other data). Data is available from 2007-01-01T00:00Z up to real-time estimated actuals.	details
GetRooftopPvPower	Get historical basic rooftop PV power estimated actuals for the requested location, derived from satellite (clouds and irradiance over non-polar continental areas) and numerical weather models (other data). Attention hobbyist users If you have a hobbyist user account please use the Rooftop Sites (Hobbyist) endpoints.	details
GetAdvancedPvPower	Get historical advanced PV power estimated actuals for the requested location, derived from satellite (clouds and irradiance over non-polar continental areas) and numerical weather models (other data).	details
