ESTI Meteo Tower

Comprehensive metrological solar resource data are essential for evaluating the results of the European Solar Test Installation (ESTI)'s outdoor exposure testing on PV modules. The ESTI meteo tower, located in Ispra (Italy), measures and records the following parameters:
  • Global irradiation on 0, 45, 60 and 90° planes
  • Diffuse irradiation 
  • Relative humidity
  • Wind speed
  • Wind direction
  • Rain gauge 
  • Ambient temperature
  • Local Barometric Pressure
The data are publicly available on the ESTI meteo tower website.
