Performance Evaluation of Standalone Solar Powered Water Irrigation System Using DC Pump

Abstract

In the present scenario, the demand for agriculture is increasing abruptly due to the population in the world. In agriculture, irrigation plays a major role. As it requires electricity supply to irrigate the field, farmers find it an additional expense towards the electricity cost and also it is challenging to provide the uninterrupted supply to farmers. Though our government provides subsidies, the demand for electricity throughout the world is increasing. Especially as we tend to rely on agriculture for our daily life and considering the hardship faced by the farmers, nowadays people tend to move towards solar power but the existing grid connected system may lead to high cost, need of more space, and needs proper maintenance. The use of DC pumps overthrows the struggles of farmers and to pave a way to increases agricultural practices. This system consist of array of 3 panels connected to the DC motor of 0.75 kW. The use of DC motor assists in storing the power generated by the system and can be used during night time or in case of emergency situation, providing uninterrupted power supply. This system serves the important advantage to the environment that it reduces CO2 emission as it eliminates the use of fuel for pumps to operate. As the system is designed autonomous, it also reduces space occupancy. The panel setup is placed in an appropriate location so that it could receive more radiation, as a result generates maximum power. The parameters like power, power quality and pumping rate has also been analyzed under varying atmospheric conditions under specific period of time. Thus this system provides the more efficient way to utilize the solar power and to generate maximum energy for use.
