  • Determine the difference between DNI measured with a pyrheliometer and the amount of direct radiation that can be used in your concentrating PV or thermal system.
  • Lower your CSP or CPV systems levelized cost of electricity (LCOE) by optimizing the receiver size: The optimal size of the receiver depends of the distribution of circumsolar radiation at a site. 
  • Understand the influence of CSR radiation on the efficiency of your CPV or CSP System.
  • Include CSR aspects in your pre-installation solar radiation measurement campaigns.
