A study on Optimization of Tilt Angle of the Solar Panel using Soft-Computing and Solar Tracking method is presented in this paper. Radiations being of different types provide different power outputs from the panel at different tilt angles. Thus the tilt angle, if optimised can yield more power from the same panel. An analysis on the optimisation of the tilt angle was done. In the first phase, the tilt angle was optimized on a monthly basis using genetic algorithm and it was found that a significant power gain can be obtained. The optimum tilt angles were noted for Kolkata, India [Lat. 22.56670 N, Lon. 88.36670 E]. In the second phase of this study, a dual axis solar tracker was developed following the soft computing based result. During the application of this tracker, a noteworthy power gain was achieved, when compared to the panel kept at no tilt with respect to the ground. The readings for this study were taken at Techno India, Kolkata, India [Lat. 22.5760N, Lon. 88.4280E]. The tracker provides an additional safety to the panel from shadows reducing the possibility of the hot-spot effect significantly.
