This folder contains meteorological and panel production data and metadata from the solar PV project - Southerly Winds Increase the Electricity Generated by Solar Photovoltaic Systems, available at: https://www.sciencedirect.com/science/article/abs/pii/S0038092X20303303?dgcid=author

The project aim was to improve our understanding of meteorological effects on solar panel electricity output in a field-based setting while demonstrating how differences in exposed surface area under northerly and southerly winds can affect the efficacy of surface cooling with implications for electricity output. 

The meteorological data was obtained from Westmill Solar Park, Oxfordshire, where 4 logging stations were set up in areas near the perimeter of the site. 
Westmill Solar Park has a rated capacity of 5MW. The location is latitude 51.619672 degrees and longitude -1.645495 degrees.
The site operator provided electricity output and two sets of PV panel temperature readings, which were averaged for analysis; the electricity output value equals the amount generated by the whole solar park over the 15 minute period up to the measurement time.

Folder contents:

Metadata_Northerly_and_Southerly_Wind_Groups.pdf = A file containing a description of how wind groups were determined.
Solar_Park_Equipment_Metadata.pdf = A file containing details of the equipment used to measure the meteorological variables.
Wind_Direction_Matches_with_Corresponding_Meteorological_and_Panel_Data.csv = A file containing the wind direction matches. Ambient temperature, wind speed, relative humidity, total and diffuse PAR values were categorised into bins. Northerly and southerly wind subsets were compared and paired if the bin codes for all corresponding variables (ambient temperature, wind speed, relative humidity, total and diffuse PAR) matched.
Panel_and_Meteorological_Data_at_Solar_Noon.csv = A file containing all instrument readings at solar noon (UTC) for a period of 1 year between 27th June 2013 and 27th June 2014.

Measurement and format details:

Ambient temperature and relative humidity measured at 0.5m height at 4 locations.
Total PAR (Photosynthetically Active Radiation) and diffuse PAR measured at 1.3m height at 1 location.
Wind speed and wind direction measured at 1.5m height at 1 location.

Date and Time format dd/mm/yyyy HH:MM in UTC.
