Solar irradiance and agroclimatology for any location on Earth — as an API over NASA POWER (Prediction Of Worldwide Energy Resources), derived from NASA satellite and reanalysis data. Get the solar resource needed to size and assess PV and CSP systems: global (GHI), direct-normal (DNI) and diffuse horizontal irradiance, clear-sky irradiance and the clearness index — either as long-term monthly climatology normals for quick site assessment, or as a daily time series for a date range (1981-present). The same call also serves meteorology — temperature, wind speed, relative humidity and precipitation — making it ideal for solar energy, agriculture, building-energy modelling and climate work. From cloudy Berlin to the Sahara, it turns a coordinate into bankable solar and climate data. A solar-resource / agroclimatology data source — distinct from PV-system energy simulation (PVGIS) and historical-weather records. Open data from NASA POWER.

Solar photovoltaic potential for any location on Earth, powered by the EU JRC PVGIS (Photovoltaic Geographical Information System). Estimate how much energy a solar PV system would produce at a given coordinate — yearly and month-by-month output in kWh, the in-plane solar irradiation and a breakdown of system losses (angle-of-incidence, spectral, temperature) — for any panel size, fixed tilt and azimuth; find the optimal panel tilt and orientation that maximises annual output; and read the long-term monthly global horizontal solar irradiation. Covers most of the world (excluding polar and open-ocean areas) from years of satellite-based solar data. Ideal for solar installers and calculators, renewable-energy planning, home-energy and roof-potential tools, and climate / sustainability apps. Open data from EU JRC PVGIS.
