This connector is used for the solar radiation transport between components. The variables in the connector are:
IrrDir direct solar radiation energy fluent rate in [W/m2], IrrDif diffuse solar radiation energy fluent rate in [W/m2], angleDegInc Incident angle of the direct solar radiation [deg], angleDegAziSun Azimuth angle of the sun [deg], angleDegHeightSun Height angle of the sun [deg]
According to the Modelica sign convention, a positive mass flow rate m_flow is considered to flow into a component. This convention has to be used whenever this connector is used in a model class.
