A solar tracker is a device that orients a payloads can be toward the sun. Trackers are used to minimize the angle of incidence between the incoming sunlight and photovoltaic panel. This increases the amount of energy produced from a fixed amount of installed power generating capacity. In standard photovoltaic applications, it is estimated that trackers are used in at least 85% of commercial installations greater than 1MW from 2009 to 2012. This study is concerned about the structure design of a low coast and entry level dual axis solar tracker. This research purpose is to propose and verify a method to achieve higher product quality, lower costs, and far less physical testing. As a result of the new mechanism development, the volume of moving parts and the weight of main parts decreased by 46.8% and 20% respectively

It is necessary to secure the safety for the horizontal capacity of solar tracker system. Therefore, this study evaluates the structural capacity of the horizontal connections through the structural experiment under various variables.

Recently, the rotational solar tracker system is presented for the high electric efficiency. The horizontal rotation tracker is the structure for rotationg horizontally the most important part. However, it is difficult to secure the safety and maintenance in solar tracker systems. Therefore, this study suggests the reasonable structure type for horizontal rotational solar tracker through the strength reinforcement of the structure to ensure stability.

Solar tracker structure is usually installed outdoor. Therefore, the structure can be influenced by wind load and snow load. In this study, the safety evaluation is performed by analyzing the results according to structural modelling and analysis for solar tracker structure. Also, solar tracker structure module is presented under the various design variables.

This study presents the tracker structural composition system for the effective angle variation of solar module. Also, the structural performance is evaluated through the structural modelling and analysis and the field application is considered.
