Fredy Posted September 22, 2016 Share Posted September 22, 2016 Good afternoonI'm comparing 3 different Meteo databases and in this 3 simulations i used all parameters losses modules inverters are the same just changed the Meteo,I get the following results: I don’t understand why Meteonorm VS PVgis have almost the same Global Radiation and the PR changes so much (81.6 - 82.2)?and Meteonorm VS Meteosat have the same difference on PR (81.6 - 82.2), with lower radiation and higher GlobINC i have more gain in (Hor / Inc) that i understandIs there some other parameter that affects this when using different Meteo files?Thank you for your support Link to comment Share on other sites More sharing options...
André Mermoud Posted October 1, 2016 Share Posted October 1, 2016 The main differences between these different runs probably come from the Diffuse part in these data. The transposition (i.e. the GlobInc/GlobHor ratio) is highly dependent on the Diffuse fraction, whatever the model used. Link to comment Share on other sites More sharing options...
