![]() These methods represent the ratio of incident solar irradiation on a building or land to unobstructed solar irradiation received at the same location during the chosen period of time, day or year, respectively. There are some methods used for energy evaluation on urban structures and sizing of building sites. The distance between large buildings and their heights restrict the available direct sunlight. Settlements and architectures of the buildings have become more important in large cities during the progress of urbanization, particularly at the point of effective usage of the sun. However, distant or close mountains, fast growing trees, and tall buildings are considerable factors compared to temporary shaders. More often than that, the shading caused by snow affects only a couple of PV panel rows. In addition, some of the array arrangements established vertically or horizontally may reduce the effects of air conditions. Temporary shading elements such as leaves in forested areas, snow in mountainous areas, bird droppings, and air pollution are not significant factors as long as the system is self-clean. Some of the most important investigations in terms of improving the power system are the evaluation of the installation site, analysis of the shading resulting from the environmental obstructions, and weather conditions. One of the different studies on efficient improvement of PV power system is to use a new energy storage technology used in the plant due to wide range of power outputs, high storage efficiency, rapid response, low maintenance cost, and long lifecycle. On the other hand, efficiency of the solar power system can be increased through many measurements and investigations. By the way, PV panels and features of the installation site greatly affect the performance of solar power system. However, the evaluation of power losses in solar cells is a key issue in identifying technological and material problems. The importance of carbon-free energy generation was recognized solar electricity or photovoltaic (PV) technology has attracted attention as a potentially widespread approach to sustainable energy generation. The device is explained with an application on the installation area selected as a pilot site, Denizli, in Turkey. Thus, exposure duration of the PV panels to the sunlight can be measured effectively. In this study, the shading analysis tools are introduced briefly, and a new and different device is developed and explained to analyze shading effect of the environmental obstruction on the site on which the solar power system will be established. Afterwards, changes in solar data throughout the year must be evaluated along with the identification of obstructions surrounding the installation site in order to analyze shading effects on productivity of the solar power system. Shading analyzer systems are necessary for selecting the most suitable installation site to sustain enough solar power.
