Energy plays a fundamental role in the daily works of humans. Over the last few decades, there is tremendous growth in energy consumption in the world. As solar energy is an ultimate source of clean energy that can help overcome air pollution and global warming. Hence, Solar energy can be a solution to tackle the increase in demand for energy and solve environmental issues. The conversion of solar energy into electrical energy efficiently depends on the location, orientation, and type of photovoltaic cells. It has gained much attention in the world, and the studies carried out on this subject have gained more and more significance. The problem of converting energy efficiently and the extraction of solar energy effectively is not new for engineers. The problem for the extraction of solar energy efficiently can be solved by using the tracking system. The tracking systems are very efficient and effective as it tracks the sun throughout the day. The purpose of this study is to calculate the average total irradiation falling on the tracking surface and then determine the percentage increase in average total irradiation for single and dual-axis tracking surfaces with the fixed surface. The average total irradiation is calculated using isotropic models with the help of Solcast data in a Matlab program. The Matlab program helps to analyze, compare, and determine the increase in irradiation falling on the tracking surface. The study also focuses on a comparative study of the three isotropic models for the average monthly irradiation at Jodhpur. As a result, it was found that single and dual-axis tracking surface shows an average of approximate 12.17% and 21.2% increase in average monthly total irradiation compared to a fixed surface. The comparative study shows that the Badescu and Liu&Jordan isotropic models are much more accurate.The study also focuses on solar energy potential in solar trees. It has two advantages over the flat configuration. First, the three-dimensional space can be utilized to increase the area to capture more solar energy. Second, a single solar tree can be used to produce more energy than a fixed configuration. The study of solar tree structure needs to be studied to improve solar energy utilization. In this study, the Solar PV tree structures are designed based on the Phyllotaxy arrangement of the leaf. The three designs of solar PV tree structures are made in Solidworks. The solar tree structure design of model 1 is based on a whorled phyllotaxy arrangement, model 2 structure design is based on an alternate phyllotaxy arrangement, and the model 3 structure design is based on a spiral phyllotaxy arrangement. The model of the solar tree structure is built, and static calculation is performed in Solid works. The design feasibility for three models of the solar tree structure is verified and compared by evaluating weld stress. As a result of the study, it was observed that the Model 3 with a spiral phyllotaxy arrangement has the least amount of stress and bending moment on its weld. Hence, it was concluded that the structural design of the solar tree for Model 3 based on a spiral phyllotaxy arrangement is safe based on the strength and rigidity criteria.
