Hi, I am comparing pv sol pvsyst and sam, i gave them same metherologival file custom made for the same system(inverter and modules are same). but in Sam and pv syst i put in Dhi(diffuse horizontal irradiance) and not in pv sol and i put all losses that i can in all software to 0. Now difference in result from pvsyst and sam is small but difference betweem them and pv sol is big around 17 percent can that be because of DHi because pv sol calculates it by itself??
This is for my master thesis.
Thanks
