Battery Less Solar Photovoltaic Power Generation System To Supply Electrical Power To Utilities Throughout Day

Abstract: The invention relates to the solar assisted open well water pumping setup along with a small hydro turbine can develop a sustainable energy technology, which eliminates batteries from solar photovoltaic power system and also effectively utilize the depth of the open wells. In this configuration, when solar power is available, the electrical power is fed directly to the local electrical loads and the excess electrical power is used to pump the water from the open well and is collected in a ground level reservoir tank. When the amount of solar power is low or unavailable, the water stored in the reservoir tank is allowed to flow into the well through a water turbine of low power output capacity. The depth of the open well can be effectively utilized as the head required for the turbine operation. Water turbine rotates and drives a generator which produces electricity. After power generation the water is collected back into the well. Thus the excess solar power is stored and reproduced without using battery. This scheme taps the available resources and generates power at the load centre reducing electrical losses, thereby providing a sustainable renewable power generation for agriculture.
