Alternative Energy On Sources

With alternative energies still sitting on the back burner, new and improved systems are needed to pique interest and help move them further into the limelight. Solar energy is an abundant, clean, alternative energy that can improve environmental pollution. The rapid increase in population and economic development has created potential problems such as an energy crisis and global warming. There is a growing demand for renewable energy needed worldwide, and the utilization of it could be a solution to environmental problems.

Systems built to auto-track the sun would harvest more energy that could be used in place of fossil fuels, which, in turn, would lessen any economic problems created by humanity’s dependence on them.

This project will focus on increasing the efficiency of a solar panel module by implementing a GPS receiver to track the position of the sun which in return gives the ability to produce more power than other tracking devices employing light sensing diodes or gases. The diodes and gases used in these other methods are not produced cleanly and are also fragile and more sensitive.

The growing demand for renewable energy is seen worldwide and systems that auto track the sun will allow increased sunlight exposure as well as amplify the production of energy. The physics of the PV cell is very similar to the classic p-n junction diode. The use of solar energy is through photovoltaic conversion, the PV cell converts the sunlight directly into DC current by the PV effect. A PV panel is a packaged interconnected assembly of PV cells.

To maximize the power output from the PV panels they are kept in an optimum position, perpendicular to the solar radiation during the day.

If compared to a fixed panel, a mobile PV panel, driven by a sun tracker, will consistently show a boost in the energy gain. A GPS solar tracker proves to be the best at harvesting the most energy since it relies on proven equations and technology to track the sun. A dual-axis GPS guided solar tracking system is ideal for maximum production of energy, it follows the sun’s path and faces it at a critical absorption angle at all times. The efficiency is increased by using the GPS chip to acquire the systems latitude, time, and day of the year. These values are then sent to the microprocessor and applied to the four astronomical equations that predict the location of the sun. The system then adjusts accordingly. Finally, as the production of clean energy increases by people, the utility companies will be able to use any of the extra energy produced to boost the consistency of power distribution during the grids peak operating hours.
