Solar PV (PVGIS) API

degraded 3,489 Subscribers

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.

Solar Resource API

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.

Sunrise & Sunset API

Sunrise, sunset, solar noon, day length and the civil, nautical and astronomical twilight phases for any latitude/longitude and date — plus a multi-day range. Useful for agriculture, solar energy, photography, outdoor scheduling, smart-home automation and astronomy apps.

Carbon Intensity API

Great Britain\x27s electricity grid carbon intensity as an API, from the official National Grid ESO Carbon Intensity service. Get the live national carbon intensity in grams of CO2 per kWh with its index (very low to very high), the current generation mix showing exactly how much of the grid is gas, wind, solar, nuclear, biomass, hydro, coal and imports right now (with the renewable and zero-carbon percentages worked out for you), today\x27s half-hourly intensity timeline, the carbon intensity of all 18 GB regions, the intensity and fuel mix for any UK postcode, and the gCO2/kWh emission factor of each fuel type. This is exactly the data you need to shift EV charging, heat pumps, laundry and batteries to the greenest, cheapest half-hours. Perfect for smart-home and energy apps, EV-charging schedulers, sustainability dashboards, carbon-aware computing and climate tools. Covers Great Britain. No accounts, no upstream key.

Power Plants API

The WRI Global Power Plant Database as an API — 34,900+ power stations across 167 countries (~5,700 GW total capacity). Look up any plant by its WRI/GPPD id (e.g. WRI1000452 → Three Gorges Dam, 22,500 MW hydro); search by name, country, fuel type or capacity range; or find every power station within a radius of any coordinate (great-circle distance, optional fuel filter). Each record carries the installed capacity (MW), primary fuel (Solar, Hydro, Wind, Gas, Coal, Nuclear, …), country, latitude/longitude, commissioning year and owner. Ideal for energy dashboards, ESG/climate analytics, grid and infrastructure tools.
