Industrials and project developers of solar power plants (photovoltaic, solar concentrating technologies) have identified the surface solar irradiance (SSI) and its components as an essential variable for their business development. Policy-makers need the SSI to set up energy policies at local to national levels. Such projects address:
- The solar resource prospective with solar maps integrated in GIS.
- The long-term solar resource assessment for a specific site with time series of SSI for technical sizing and yield report simulations.
- The monitoring of existing solar power plant for operation and maintenance.
- The multi-horizon forecast for energy storage, planning or participation to electricity spot market.
In-situ pyranometric sensors are deemed to provide the best possible assessment of the SSI at a given location. They serve as a reference to assess the quality of the two other components: satellite-derived and numerical weather models.
A new platform has been deployed and it enables (i) visualisisation of sensor locations on a map, (ii) visualisation of measurements as time series as plots and in tabular form, (iii) display of sensor metadata at different levels of detail, (iv) computation and statistical representation of time series according to the types of in-situ measurements (eg. solar 2D view, wind roses) and (v) download of observation data for offline processing.
It is based on the 52°North SWE (Sensor Web Enablement) solution respecting OGC SOS (Sensor Observation Service) standard and GEOSS recommendation on interoperability.
