Abstract
In recent days, solar energy is one of the key sustainable power sources and is picking up its prominence rapidly. When the Sun's rays strike the solar system perpendicularly, the system gains the most energy. Solar energy can be made more feasible by amplifying its efficiency. Thus, solar tracking helps to track the sun and make the setup to receive the irradiation perpendicular at all time. In order to yield a real time solution and to maximize the energy efficiency, solar systems are continually tracked. In this paper solar tracking is designedfor a Parabolic Linear Fresnel Collector (PLFC) system. It is a modified solar collector which is a combination of Parabolic Trough Collector (PTC) and Linear Fresnel Collector (LFC). It combines the features of both PTC and LFC which is compact and efficient.Many individual Linear Fresnel mirrors are pivoted with their midpoints in a parabolic profile. The centre plate is employed with a geared stepper motor. All the discretised Fresnel mirrors are interlinked with a linkage mechanism and therefore rotating movements of the stepper motor make all the mirrors to pivot simultaneously. In this paper, a solar tracking system is designed for the PLFC system, the tracking is based on an embedded tracking design. MAT-lab software is used to calculate the tracking angle of the Fresnel mirrors with respect to Sun’s position using Sun Position Algorithm. The Arduino microcontroller and a stepper motor are used to pivot the Fresnel mirrors according to the instant tracking angle. The objective of this paper is to track the discretised plates of modifiedPLFC solar system based on the sun’s position. The proposed solar tracking helps to increase its efficiency by pivoting the mirrors to receive maximum solar irradiation.
