Abstract: A sustainable energy supply is required in Malaysia to meet the increasing electricity demand with rapid growing in population and economy. Photovoltaic solar panel is most suitable alternative way to generate electricity in Malaysia where most of its location receives large number of solar radiation throughout the year. However, fixed solar panel is more preferred than tracking panel because it is cost effective. In present work, the power output and efficiency of single-axis tracking solar panel is compared with fixed solar panel by experimentally in East Coast Malaysia. A single-axis tracking panel produces higher power output than fixed panel up to 28W. During this time, the average efficiency of tracking panel was about 66.70% and fixed panel was 39.96%. Hence, the percentage increment on average power output using tracking panel reached up to 66.92% compare to fixed panel during this period. The tracking panel module efficiency was higher than fixed panel for the same period and can reach up to 28.9% at 6.00p.m. In conclusion, single-axis tracking panel is more efficient than fixed panel in premeridian and postmeridian. Thus, it produces higher power output than fixed panel which means it utilize the most of available solar radiation effectively and this will reduce payback period of the initial investment cost.

Abstract: The performance of photovoltaic (PV) system depends upon the orientation and the site climatic conditions. Solar PV tracking systems align the modules perpendicular to the incoming solar radiation. In this paper, six locations with latitudes 0° through 55° were selected to investigate the PV system performance using single-axis (horizontal and vertical) and two-axis tracking systems compared to the fixed south-oriented PV system. It was found that single-axis (vertical axis) tracker optimally tilted is the most promising for sites near the equator and achieves around 19% more energy output over the fixed south-oriented solar panel system. Moreover, it is considered simpler compared to the two-axis tracking system. It is true that the two-axis tracking system could harvest around 4% more energy than the vertical axis tracker optimally tilted system for sites near and far from the equator. However, such increase in energy may not sound feasible as the two-axis system is consuming more power for tracking and considered more complicated compared to the vertical axis tracking system. The novelty of this work is that, it introduces a new concept for the optimum tilt for the single-axis (vertical axis) tracking system.
