o the high peak has northern, eastern and southern oriented steep slopes
o the more red, the higher beam irradiance calculated by the r.sun command above
o the southern oriented footslopes show a high beam irradiance (as exptected)
o the southern oriented and very steep slopes around the peak show a similar low beam irradiance as the northern slopes (not expected)
I have issues to interpret the results, especially the last pattern:
o Could be the lower beam irradiance in the very southern oriented slopes nearby the peak due to the very steep slope?
o Do slopes with a high inclination (though southern oriented) reduce beam irradiance in the implemented model?
