Collector type:

Select the desired collector model


 

Slope [°]:

[°]

Type the angle in degrees
between the collector and the horizontal plane


 

Azimuth [°]:

[°]

Type the angle (in degrees) between the horizontal projection of the collector normal and the local meridian. By convention, a value of 0 indicates South; the angle sign has no relevance in the present model.
