A weather station is a system integrated by sensor or measure devices of different typology whose goal is to measure the time variability of the weather conditions from a specific site, through a discrete sampling of physic variables called observations.

Currently, the Instituto de Sistemas Fotovoltaicos Concentration (ISFOC), owns a net of automatic-measuring weather stations, being operative 24 hours a day. 365 days a year. ISFOC automatic weather stations are designed to measure and characterise of the solar radiation, ranging all its components, from global to direct and diffuse, although they focuses on the energy directly coming from the solar disc, the Direct Solar Radiation (DNI), the one feeding the CPV technology. This measuring network's main goal is to support the research activity of our Institute, in the common fiel of the Meteorology and the Concentration photovoltaic Technology (CPV). ISFOC automatic weather stations are in compliance with the Spanish R&D General Plan targets dor Solar Concentration Photovoltaics, issued by the own Institute in 2008 in regard with Castile- La Mancha region needs. Those are listed below:

  • Knowing and quantifying the solar resource of Castile- La Mancha, by analysing its spatial and temporal complexity.
  • Developing methodologies for the short-term prediction of the solar resource (hourly and daily).
  • Contributing to improve the Spanish national network of measuring stations for solar radiation, by creating an integrated database of solar radiation observations, by ranging all its components (global, direct and diffuse) as well as the solar spectrum measures, being this element really important for understanding and improving the high-efficiency cells' performance (>40%)

ISFOC automatic measuring network is made up by four weather stations installed next to the ISFOC CPV plants, in Castile-LA Mancha(Spain).
