AUTOMATIC SOLAR TRACKING SYSTEM TO MAXIMIZE POWER EXTRACTION

In this technological world the need for renewable energy resources has been very essential rather than nonrenewable resources, because cost of the non- renewable resources sums to be a larger one and it will not provide an eco-friendly environment. So, in this concept we introduce the Parabolic Solar Tracking System instead of the flat solar tracking system which is very common in our day today life. By implementing parabolic solar tracking system, which uses the multi-junction solar cells with parabolic mirror reflectors the efficiency can be improved up to 39.2% compared to the single-junction cells. This enhanced feature is due to the infinite number of junction in the multi-junction solar cell and the shape of the reflectors that is designed. The dual-axis tracking system is controlled by PIC 18F4550 microcontroller depending upon the control signal given by LDR.
