Abstract
Renewable energy solutions are becoming increasingly popular. Photovoltaic (solar) systems are but one
example. Maximizing power output from a solar system is desirable to increase efficiency. In order to maximize power
output from solar panels, one needs to keep the panels aligned with the sun. As such, a means of tracking the sun is
required. This is definitely a more cost effective solution than purchasing additional solar panels. It has been
estimated that the yield from solar panels can be increased by 30 to 60 percent by utilizing a tracking system instead of
a stationary array. In this paper, a prototype for a microcontroller based multi-function solar tracking system is
described, which will keep the solar panels aligned with the sun in order to maximize efficiency. The maximum power
point tracking (MPPT) data can be transmitted in real time to other solar systems in need of this data.
