Konstantina Posted October 29, 2013 Share Posted October 29, 2013 Dear Andre,the value of irradiance that appears in the simulation result (the first number in the diagram of the report) in kWh/m2 is the horizontal irradiance without any losses at all?There are not cloud losses? And if I want to find the cloud losses how can I find them, there are in the meteo databases?Thank you very much. Link to comment Share on other sites More sharing options...
André Mermoud Posted October 30, 2013 Share Posted October 30, 2013 The meteo data are the irradiance as measured at ground. They include the cloud losses of course...If you want to evaluate the cloud losses, you have to calculate the "Clear day" model ("Tools" / "Tables/Graphs of solar parameters") and do the difference.
