cintiakagueyama Posted October 4 Share Posted October 4 Hi, When I simulate a project and generate and output file with all losses and energy, I noticed inconsistency between the LID loss infomed on the waterfall report, and the one I calculate based on the output file. I use EArrayNom and then discount all losses (degradation, irradiance, temperature, shading, spectral, quality), resulting in an Energy value, and then divide LID loss by it: LID loss (%) = LIDloss(mwh)/Energy(mwh) The LID loss in MWh being the sum of the LID loss column in the 8670 output file. But I cannot get to the same % loss result. An example: on Report, LID loss is 1%, but the calculated one is 0.931%. Is there another non accounted loss in between? How this % loss presented on the report is calculated? Thank you Link to comment Share on other sites More sharing options...
Michele Oliosi Posted October 5 Share Posted October 5 Hi, did you also check the same operation hour by hour ? Since you have the 8760 file is a good cross-check in principle. Let us know how it looks. Link to comment Share on other sites More sharing options...
