  Hello everyone,nI am confused about the calculation of surface incident radiation. I have a glass outer surface in solar collector. The sun irradiation should be maximum 1400 as I set it constant. But when I get the surface incident radiation I found it varies and increase with the calculation reached to 2500 w/m2 !nso what does that mean please?nThanks n

  Hello,nThe Surface Incident Radiation is the net incoming radiation heat flux on a surface and for that, it is only defined on surfaces. Surface Incident Radiation is the total radiant load hitting the surface (which will subsequently be absorbed, transmitted, and reflected).nKarthikn
