The importance of renewable energy sources is increasing in our world. Solar energy is the most natural, unlimited, ergonomic, environmentally friendly, useful and available everywhere source among of the renewable energy sources. The installed capacity of solar energy in electricity generation is increasing rapidly all of the countries. The most important part of photovoltaic power installed projects is cost-effective of projects for these systems installations because millions of dollars are being invested to it. This study is crucial in this respect. An example of location is determined and is designed for photovoltaic installation according to the European Commission Photovoltaic Geographical Information System for the city of Van where is the east of Turkey. Needs of the system, system equipments, design style and how it should be established are indicated and worked while considering the geographical coordinates of the location. A detailed study has been prepared taking into consideration all these data. It is a fact that such a system designing would serve as an example for all photovoltaic applications in the world.

In this study, an open-loop, two axes movable photovoltaic (PV) solar tracker is designed and analyzed as detailed. Its performance over a fixed tilted (37o) PV system is evaluated theoretically and experimentally for the climatic condition of Denizli, Turkey. Two DC actuators motors are used for the movement of the solar tracker. In addition to the experimental data, a computer program in Visual C#2005 that uses the equations for the solar radiation values of fixed and moving systems is developed. The performance difference of a fixed tilt PV panel and a two-axis moving PV panel was compared for months of May and June and it was found that the energy generation increases nearly 64% for tracking system when it is compared with fixed PV system. Moreover, the performance improvement values for each month are obtained by using the developed and designed computer program.
