By using geometric analysis method and the Matlab software simulation
the vertical section parabolic model of a 5kW disc type solar collector was established
and the model parameters were set.The three dimensional model for this collector was built up by the Solidworks software and optical simulation and focal spot analysis on this 3D model were performed via the TracePro software.The simulation results show the opening diameter of the vertical section parabola of the 5kW disc type solar collector is 8m.The theoretical concentration ratio of the collector turns the largest when the focal length of is 4.812 6m.The actual permissible error angle of the system is lower than 0.58°.
