Fetch monthly radiation data from PVGIS website (by API)
between start and end year (limit years are from 2005 to 2020).
Fetched variables are Hrad = horizontal plane irradiation and
DGratio = ratio of diffuse to global radiation (in horizontal plane).
! YOU NEED AN INTERNET CONNECTION TO ACCESS THE DATA BY API !
Usage
get_monthly_radiations(latitude, longitude, start_year = 2005, end_year = 2020)

Arguments
- latitude
latitude of the plot
- longitude
longitude of the plot
- start_year
positive integer between 2005 and 2020 - start year on which to fetch monthly data
- end_year
positive integer between 2005 and 2020 - end year on which to fetch monthly data
Value
Monthly horizontal radiation (Hrad) and diffuse to global ratio (DGratio)
averaged between start_year and end_year
