Differences between API TMY PVGIS - PVGIS 5.1/5.2

[ManPC]

Hello everybody! 

I would really appreciate some help related to the following issue between the monthly values obtained by API PVGIS TMY (tool in PVSyst) and the data from PVGIS web:

 

I noted that the monthly values obtained by PVGIS API TMY do not correspond to the PVGIS 5.1 or 5.2 version.

Why the values are not equal -at least between API and PVGIS 5.1- (in some months is equal or nearly, but, would not it be the same data/results?)

PVSyst is using a different/older version of API PVGIS when importing the monthly data?

 

Thank you for your support.

Manuel.

Hi,

Which version of PVsyst are you using? In the latest version you can import from the 5.1 or 5.2 API, a button allows you to choose between both.

In previous versions of PVsyst, PVsyst was using a given set of years, whereas for a while the choice was not given in the PVGIS website (and didn't match the PVsyst one). I think now you can see the years considered when using the PVGIS website.
