Designed to provide high volumes of solar resource data quickly and effectively at a competitive price. Prospect for solar sites establish feasibility, or get a second opinion.
CLOUD AND IRRADIANCE TRACKING
Tracking the world's clouds in the finest detail
Designed for Solar, from the ground up. Never rely on generic weather model data again. Solcast's real time and forecast data tracks and forecasts real clouds at a resolution of 1-2km and 5 minutes. Our irradiance and PV power data is updated every 5 to 15 minutes. Aerosol and albedo effects are explicitly treated.
INTEGRATE
Integrate with your PV design workflow
Multiple file formats supports included CSV and JSON. Includes up to five API calls a month and several unmetered locations for developing your integration. Direct downloads through the API Toolkit available.
DATA ACCESS
Quickly access key irradiance and weather data via API
Provides GHI, DNI, DHI, GTI, Temperature, and wind speed. Global tilted irradiance for fixed and single access tracking systems supported.
VALIDATION
Dataset supported by independent global validation
Monthly and annual average data has low uncertainty and a quantified error range, making the data suitable for resource assessment, yield analysis, financial modelling, and any application requiring climatological irradiance data.
