Design, implementation and cost analysis of a solar powered water pump for multistoried building

Electric motors are used to pump water in multistoried building. Total power consumed by those motors is huge in urban area. By implementing a renewable energy source to run those motors can save energy from national grid. The purpose of this paper is to provide information about planning and installation of solar powered water pumping systems by using Thin Film PV (Photo Voltaic) Module. 20 panels of 95 Watt are mounted by using movable concrete pillar for flexibility. A 3D design was created by using SketchUp 3D to bring perfection in mounting solar panels. A three phase inverter is used to operate with higher output voltage of Thin Film PV Module. To avoid starting torque and maintenance cost, a three phase 2 HP AC water pump is used for pumping water. A four storied building is considered to lift water from reserve tank on ground. The system has been tested successfully in delivering 500 liter water in 17 minutes to the over head reserve tank at broad sunlight. Total cost for installing this project is also analyzed in this paper.
