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.
