# .AixLib.BoundaryConditions.WeatherData.Old.WeatherTRY.RadiationOnTiltedSurface.RadOnTiltedSurf_Liu

Calculates solar radiation on tilted surfaces according to Liu

## Information

#### Overview

The RadOnTiltedSurf model calculates the total radiance on a tilted surface.

#### Concept

The RadOnTiltedSurf model uses output data of the Sun model and weather data (beam and diffuse radiance on a horizontal surface for TRY format, or beam normal and global horizontal for TMY format) to compute total radiance on a tilted surface. It needs information on the tilt angle and the azimut angle of the surface, the latitude of the location and the ground reflection coefficient.

The input InDayAngleSun is not explicitly used in the model, but it is part of the partial model and it doesn't interfere with the calculations.

#### Example Results

The model is checked within the weather example as part of the weather model.

## Revisions

- March 23, 2015 by Ana Constantin:
  Adapted solar inputs so it cand work with both TRY and TMY weather format
- May 02, 2013 by Ole Odendahl:
  Formatted documentation appropriately
- March 14, 2005 by Timo Haase:
  Implemented.
