Weather monitoring

The Sheffield Solar Farm has its own pyranometer, an SPN 1 Sunshine Pyranometer from Delta-T Devices, which measures both direct and diffuse radiation.


Features of the pyranometer are:

  • Measures solar radiation and sunshine duration
  • Global (Total) and Diffuse irradiance in W.m-2
  • DNI (Direct-Normal Irradiance) calculation
  • No moving parts, shade rings or motorised tracking

The SPN1 Sunshine Pyranometer is a meteorological class solar radiation measurement instrument with a built-in heater, and is designed for long-term outdoor exposure.
