The energy potential of the sun is immense. Despite the unlimited resource, harvesting it presents a challenge because of the limited efficiency of the photovoltaic cells. The best efficiency of most commercially available photovoltaic cells ranges between 15 and 20 percent. This paper seeks to identify a way of improving solar panel system efficiency by implementing a solar tracking method. The tracking mechanism rotates the solar panel such that it is positioned for maximum power output. The three ways of increasing the efficiency of solar panels are through increasing cell efficiency, maximizing the power output, and the use of a tracking system. Maximum Power Point Tracking (MPPT) is the process of maximizing the power output from the solar panel by keeping its operation on the knee point of P-V characteristics. MPPT technology will only offer maximum power which can be received from stationary arrays of solar panels at any given time. The technology cannot however increase the generation of power when the sun is not aligned with the system. Solar tracking is a system that is mechanized to track the position of the sun to increase power output by between 15 to 20 percent compared to stationary systems. It is a more cost-effective solution than the purchase of additional solar panels.
