Control panel to set:

  • - timestamp
  • - buildings parameters: lenght, width, height, type of roof, slope aspect
  • - cloud coverage
  • - prevalent material for the calculus of reflection
  • - grid parameters

Irradiance analytic surface of the ground. Cyan rays and brown dots indicate shadows area due to ground obstruction. Purple rays and dots indicate the shadows areas due to buildings obstruction. The grid values indicate solar irradiance.

Roof's irradiance analytic surface. Each sheet of roof has different color, because irradiance is calculated using a model which considers the angle of incidence, aspect, slope, ground and buildings obstruction.
