Comparison of Power Output from Solar PV Panels with Reflectors and Solar Tracker

In this paper, performance enhancement of solar Photo Voltaic (PV) panels has been experimented utilizing diffused reflectors and solar-tracker in other to determine the one with higher power output. An intelligent solar tracker and diffused reflector augmented systems were designed, developed and installed to compare the power output that can be generated from each of them when standing alone; and which system will achieve higher power output so as to reduce the number of PV panels required at any given time especially when cost is a major factor. For this comparative study, experimental readings were simultaneously taken from the panel, with sun tracker and the panel with diffuse reflectors aligned at 23.50 with the horizontal. Experimental results indicate appreciable increase in the overall power output of the solar panels. It is discovered that the power output of the panel with reflectors was higher from about 11 am till 2 pm, while the panel with tracking was higher at other times. The average power output of the system for a day is about the same. Looking at the cost of fabrication and the complexity of the tracking system, the reflector system is the better option
