Checking the quality of data is an essential step in achieving relevant simulation results. PVSyst proposes 4 graphs to do this evaluation :
- the time shift of monthly best days with respect to the clear day model (available on the "Check data quality" tab),
- the cloud of hourly Kt in the morning and in the evening (with the possibility to challenge shifts),
- the daily irradiance profile graph of monthly best days, and their comparison with the clear day model profile.
- and finally the ranking of days according to their clearness index.
To understand how to use those graphs, fully read our Guidelines one Data Quality Check and on Time Shift.
It is also recommended to read also our note on horizon in *.MET files.
