EVALUATION OF SOLAR PHOTOVOLTAIC WATER PUMPING SYSTEM AND IMPROVING ITS EFFICIENCY FOR DEVELOPING AN ENERGY STORAGE DEVICE

Abstract

An electricity demand in India is now at an all-time high. Agriculture accounts for 21.5 percent of total electricity use; according to sectoral demand patterns. Technology is becoming increasingly popular. PV cells are utilized to power electrical equipment because of their high energy output. Solar energy is a clean and inexpensive energy source. Solar powered water pumping is an important technology for conserving vital resources such as water and electricity. This experiment is to calculate the efficiency of solar pump and panel. It is evaluated by calculating the input and output energy of the pump and panel. By comparing the efficiencies of pump and panel we can be able to estimate the amount of loss of energy. For conserving the energy, we can also install battery and charge controller for the use of pump in dark without solar energy. It conserves energy even while the pump is working. At the time of 2-3pm the efficiency of solar panel is about 55-60% and for the pump is 50-55%. By installing the storage device, we can save 2-5% of the energy wastage. This proves to be a better implementation for conserving the energy and the use of pump at any time.
