360 DEGREE SOLAR SUN TRACKER

Abstract

This paper presents the design,
implementation, and performance evaluation of
a 360-degree dual-axis solar sun tracker, aimed
at enhancing the efficiency of photovoltaic (PV)
systems. The proposed system continuously
aligns solar panels with the sun’s position
throughout the day, maximizing energy capture
and addressing the increasing demand for
renewable energy solutions.
The tracker employs a dual-axis mechanism,
enabling both horizontal and vertical movement
for optimal solar exposure. A control system,
integrated with light-dependent resistors
(LDRs), ensures precise angular adjustments
under varying environmental conditions. A
microcontroller-based tracking algorithm
facilitates real-time positioning, improving the
adaptability and scalability of the system for
residential and commercial applications.
The design was modelled and simulated using
advanced computational tools, followed by the
development of physical prototypes for
experimental validation. Performance analysis
demonstrates a significant increase in energy
efficiency, with tracked solar panels generating
up to 40% more energy compared to fixed
installations. These findings highlight the
potential of the proposed tracking system in
optimizing solar energy generation and
promoting sustainable energy solutions.
