PV production data with ancillary PV and meteorological data including solar radiation measurements from FMI's open-air solar laboratories in Helsinki, Kuopio and Sodankylä (Finland) starting from August 2015 and ending Dec 2021

The data is described in Karhu et al. (2025) (to be submitted to Geoscience Data Journal).

The data files (*.csv) are PV system specific i.e. each data file contains all meteorological ancillary-PV and PV production data from one of the four different systems specifically. Each data file has a header explaining the variables (separated with ';'). The variables are somewhat different from site to site.

In addition to the data files there is a compressed tar archive containing hourly taken photographic images of the modules of the FMI's open-air solar laboratory in Sodankylä:
