Analysis of a Solar Panel under Different Days during a Year at GIET, Gunupur

ABSTRACT The focus of this paper is to study solar energy utilization and specifically how to use the solar energy for low scale household purposes with optimum output. The energy yields from photovoltaic panels for rooftop applications. Consideration is given as to how this energy is generated and where losses most commonly occur. The various statistical data and graphical studies of the outputs of solar panels and the batteries were taken into consideration. This are analyzed for an optimized household operation on the beginning scale. The solar cells find its application in a wide scale .Various toys, calculators and watches do use solar power for their operation. Remote lighting system is also another wide scale application of solar cells. In various remote areas it is also used for water pumping and water treatment. Solar cells find its wide scale applications in solar cars and in large ships. Being a silicon based device, it is easily available for its base products. Photo-Voltaic cell consists of a p-layer and an nlayer. It is the primary constituent of a photovoltaic cell. When sunlight falls on the p-n layers of the photo-voltaic cell, the photons contained in the sunrays strike the p-n layer and an electric current flows due the generation of electron-hole pairs. This just explains the basic working of a photo-voltaic cell at a glance. Being self-sufficient in its operation the study of solar radiations, being observed in this approach, shows that the solar radiations was low during the initial period of a day. Gradually the radiations reached to the peak and became gradually low afterwards. The battery charging current depended solely on the panel voltage and battery terminal voltage. Photo-Voltaic cell cuts the leading edge of the today’s energy focus in an environ-mental friendly way should summarize the content of the paper.
