  • FTP API - The service can deliver regularly updated PV simulation, solar radiation and meteorological data to remote FTP directories. This service provides the most comprehensive set of input parameters. Request processing is asynchronous (client registers a request, server handles the request later, client then checks for the response) and can be done regularly (e.g. once per day, per month) or occasionally. Both request and response are CSV delimited text files, thus they can easily be automated and processed in batch mode. For pricing and setting up FTP user account, please contact us. FTP API is also suitable for forecasting.
  • WS API Time Series - This standard Web service is aimed for quickly serving operational and forecast data (PV simulation, solar radiation and meteorological data) in synchronous manner (client waits for server to finish response). Due to performance reason the amount of data within single response is currently limited to period of max. 31 days regardless to data time step. Both request and response are XML documents.  WS API request parameters (represented as XML elements and attributes) are formally described by XML Schema Definition documents (XSD). By using  the schema, request or response can be verified programmatically. For this service we provide two endpoints, standard SOAP or more light REST-like access. Look for more technical information here Authentication and billing is based on API key registered with the user. Please contact us to discuss details and we will prepare a quotation.
  • WS API Long-term Averages - Standard XML-based Web service provides long-term averaged PV simulation, solar radiation and meteorological data with global coverage. The service is targeted for site prospection and feasibility. The service imitates the click on Calculate button in interactive Solargis pvPlanner application. Request and response for the service is not described in this user guide. Technical information can be found here.

Description of data available through WS API Time Series and FTP API

Solargis historical, operational and nowcasting data is seamlessly integrated with forecasting data coming from post-processed Numerical Weather Prediction model outputs. The response can be complied from different data. See the example bellow of :

We regularly update light orange regions with Solargis operational data. In the dark orange areas Solargis nowcasting data is available. Solargis historical records are also available.

Daily update affects two days - yesterday and day before yesterday. Monthly update covers the whole previous month as soon as completed. The purpose of the updates is described in this article. We gradually expands the spatial coverage of Solargis API. For the gray areas on the map, please use Solargis climData online shop. 

 

Meteorological data

Meteorological data comes from post-processed numerical weather models and is available globally. The DAY-1 and DAY-2 values are taken from NOAA GFS (resp. ECMWF IFS) data source (forecasted value). The meteorological data from GFS model are later updated with data from the NOAA CFS v2 data source (re-analysed archive data). Meteorological data for period DAY-3 or earlier can be considered as definitive.
