I am looking for tilted global irradiance data for transposition modeling. I know NREL BMS has that kind of data. But having more datasets would be better.
Dazhi Yang Dazhi, it's funny I asked a similar question a few days earlier: https://www.researchgate.net/post/Radiometric_stations_with_measurement_of_tilted_irradiance_and_albedo
Unfortunately, nobody came up with an appropriate answer...
Toufik Sebbagh What is kaggle?
Younes Ajeddig The JRC/PVGIS datasets are purely modeled...

I am looking for measured data, i.e., not modeled TMY data.
There is also measured data, hourly, daily and monthly.
And the TMY is not modelized, the TMY is produced by taking multiples parts of multiples year but they are real data, not modelized.

errr. I have no idea why you say that. If it’s gridded data, it’s modeled. In your case, that’s modeled data for sure.

hi Chris, Kaggle hosts many machine learning competitions, where the problems usually come from the industry. Hence, there might be some solar data, but I have not checked, nor believe that there is any long-term high-accuracy dataset.
hi to all,
Chris Gueymard : additionally to what Dazhi Yang have answered, kaggle can offer public data platform. I just heared about it few days ago but haven't checked it yet.

COST Action PEARL-PV is a collaborative project funded by the EU which hosts a data repository for PV applications. The datasets include Spectral/broadband irradiance, PV performance, and meteorological datasets from many institutions across Europe. I am not sure if you find the datasets that you need, but it's definitely worth giving a try.

Hi Dazhi Yang
Generally, solar radiation is not given everywhere on the inclination surface. if you want to calculate it so you calculate by the apply empirical mathematical formula for which first you should have horizontal GHI, DNI, DHI. another way you can set up your measuring tools to the inclined surface whatever you want it. one more thing the best source is that you can take data from your nearest meteorological weather station, otherwise download from different solar energy resources like NSRDB (NREL), JRC Photovoltaic Geographical Information System (PVGIS) - European Commission.
