Abstract
The increasing interests in using renewable energies are coming from solar thermal energy and solar photovoltaic systems to the micro production of electricity. Usually we already have considered the solar tracking topology in large scale applications like power plants and satellite but most of small scale applications don’t have any solar tracker system, mainly because of its high cost and complex circuit design. From that aspect, this paper confab microcontroller based one dimensional active micro-module solar tracking system, in which inexpensive LDR is used to generate reference voltage to operate microcontroller for functioning the tracking system. This system provides a fast response of tracking system to the parameters like change of light intensity as well as temperature variations. This micro-module model of tracking system can be used for small scale applications like portable electronic devices and running vehicles.
Highlights
Renewable energies can technically contribute to practically all sectors of energy demand, that is, fuel for transportation, electricity, and low temperature heat for space heating and hot water and, to a limited degree, to high temperature process heat
While many solar energy tracking projects are large-scaled [9] having complex design with maximum power point calculation [10], [11] as well as solar panels are body mounted and fuzzy based [12], the tracking system is controlled by the photovoltaic sensors and its accuracy is determined by the accuracy of mechanical model [13], [14] and combination of integrated circuit as well as large array sensor system [15]
Single axis or one dimensional solar tracker is a device having one degree of freedom that orients the solar panel to the direction of incident rays of sunlight for in one dimensional rotation for obtaining maximum power for longer duration
Summary
Renewable energies can technically contribute to practically all sectors of energy demand, that is, fuel for transportation, electricity, and low temperature heat for space heating and hot water and, to a limited degree, to high temperature process heat. This paper proposes an active micro-module solar tracking system focusing on cost effective circuital setup with less complexity based on LDR sensor with its maximum accuracy as well as microcontroller as function of ADC converter and comparator to attain maximum energy storage with less power consumption and having fast tracking response for small scale www.ijacsa.thesai.org (IJACSA) International Journal of Advanced Computer Science and Applications, Vol 5, No 1, 2014 applications as well as portable devices witsih maximum performance corresponding to different parameters.
