K Nethra, et. al.


Solar photoelectric technology is one of the most eminence resources of sustainable energy. However, the contemporary solar photoelectric system has consequential hindrance, such as high cost compared to fossil fuel energy resources, intermittency and low efficiency.  Apprehending maximal energy from the sun by using photoelectric system is formidable. Various aspects that influence the energy yield of such system comprises of photoelectric material, geographical position of solar illumination, angle of sun prevalence, weather and ambient temperature, orientation of the panel. Photovoltaic panels are used to convert the sun’s radiation to electrical energy, but since these cells are placed at a fixed angle, the efficiency is low so has to overcome this, we go with the tracking system. In this paper, dual axis solar tracking system with data logger is been implemented. Hardware part includes solar panel, LDR’s, two geared DC motors, resistors, transistor, relays etc, and  the software part has an Arduino programming used for tracking system and  for logging the voltage and current column.
