Two interactive and practical methods for optimization of tracker allocation in a given land

The purpose of this paper is proposals of two interactive methods of tracker allocation effective to relatively smaller installation. Interaction helps designers to consider every detail of the limitation and possibly more accurate approach to the project of narrow land space rather than blindly relying mathematical optimum calculation. One is Overlay of skewed rectangular mesh method. This is a simple implementation of classical optimization calculation to interactive environment. Another is Butterfly method. The idea of using butterfly pattern was first invented by Spanish engineer, Dobon, and often called Dobon’s butterfly in European regions. The original definition is the contour plot on the influence shading from a single tracker. We have improved this method for interactive design tool.
