Variant Menu:
System Definition > Collector Array > Parameters > Shading
Define the parameters for shading here.
On the Parameters page, enter a new reference for each modified shading.
You can also choose Shading from Above if the collectors are, for example, mounted on a facade with roof overhangs, etc.
- Upper Limiting Angle: If the solar altitude is higher than the upper limiting angle, the entire collector array is shaded.
- Lower Limiting Angle: If the solar altitude is lower than the lower limiting angle, the collector array is not shaded. If the solar altitude is higher than the lower limiting angle and lower than the upper limiting angle, irradiation on the collector surface is proportionally reduced. Azimuth angle entries are referenced to the south, with East as -90° and West as +90°.
