Solarian Posted June 7, 2017 Share Posted June 7, 2017 Dear Sir,I imported ASCII meteo file without success. It says' The clearness index of the best days is very high with respect to the clear day model.' I don't have time shift or location problems. PVsyst is giving as a solution 'Please check the units or the solarimeter calibration' but I don't know how to do. So could you please help me regarding above problem?e-mail: onur.gunes@solarian.com.trBest RegardsOG Link to comment Share on other sites More sharing options...

André Mermoud Posted June 2, 2018 Share Posted June 2, 2018 Meteo data are subject to some "rules". For example, we have a model for the clear sky conditions, with an accuracy of 2-3% towards high values. The meteo data cannot be too high with respect to this model. If so, they are doubtful, you should choose another meteo data source. Link to comment Share on other sites More sharing options...
