Composite materials have become the buzzword of researchers and industrialists owing to its potent advantages over conventional metals. In particular, glass epoxy composite has gained more significance due to its light weight, enhanced properties and low cost, finds wide application of automobile and Aircraft industry. In this paper a detailed review of literature works is described. The primary aim of this paper is to compare glass fiber reinforced plastic with steel leaf spring. In automobile sector steel leaf spring is used in suspension system, which can be replaced by composite material owing to its high strength to weight ratio. Also, composite materials have more elastic strain energy storage capacity. © Research India Publications.

This review paper concentrates on the issues related to the electromagnetic interferences (EMI) generated by the switching devices used in the power processing circuits of isolated or utility connected photovoltaic (PV) energy conversion systems. The EMI generated due to the fast switching devices are normally classified into conducted EMI (150kHz-30MHz) and radiated EMI (30MHz-1GHz). The conducted EMI is further categorized as common mode (CM) and differential mode (DM). This paper also presents an overview of mitigation techniques and the possibly implemented techniques in the EMI issues of PV Systems. © Research India Publications.

The efficiency of photovoltaic panel can be increased if it is placed in such a manner that incidence angle is null or almost small in respect to solar irradiation. This can be obtained by tracking the sun for movable structure and by proper selection of inclination angle for fixed structure and positioning of LDR. A case study is presented for deciding the optimum inclination angle for maximizing the output power of fixed structure PV panel in Ariyalur region of Tamil nadu state (India). To examine the effect of inclination angle on the output power of the PV panel, three PV panels have been installed at 30°, 40° & 45° angle of inclination.The values of open circuit voltage Voc and short circuit current Isc were measured on hourly basis for twelve month in the year 2014.The observation have been analyzed for finding the optimum angle of inclination of PV panel. Inclination angle is selected by LDR group output. © Research India Publications.
