Design of solar tracking system based on sun contour for photo voltaic (PV) system in Kuwait

Abstract

Renewable energy is the path for a sustainable future. The development in this field is progressing rapidly and solar energy is at the heart of this development. The performance and efficiency limitations are the main obstacles preventing solar energy from fulfilling its potential. This research intends to improve the performance of solar panels by identifying and optimizing the affecting factors. In this thesis, a top-down approach of solar PV planning and optimization methodology is developed to enable high-performance at minimum costs. This research aimed at analysing a photo voltaic (PV) solar tracker design based on the advantage of efficient power tracking. The research further proposed a photo voltaic (PV) solar tracker design based on the advantage of efficient power tracking Objective of this research is to design PV tracking system with a low-precision, low-cost and high-availability solar tracking mechanism and control system. The design methodology considers the installation location (latitude and azimuth) as a starting point for establishing an adequate angular range, simultaneity the aspects of available technology and the knowledge accords to developer. Finally, the design technique is experimentally validated by the implementation of a solar tracker at latitude of 28° longitude of 109° and evaluates the efficiency on a specific day. According to result (MPPT efficiency above 95%) the feasibility of this type of solar tracker for latitudes close to or greater than 30° is highlighted, given that this tracking system costs significantly less than traditional commercial systems as slew drive with its incorporation of lower-resolution azimuth tracking mechanisms. It also increases collection efficiency, just as continuous or time-based dual-axis solar trackers do, without the more complex controls and mechanisms of these designs. The results of this research demonstrate the success of the proposed extension in achieving the objectives of this study and for future research work.
