GSM Module Operated Solar Powered Water Pump

This paper deals with the design of solar tracking system to harness maximum solar energy that is converted into electrical energy which in turn is used to power the irrigation system. The designed single axis solar tracker device, on the basis of LDR sensor values, orients the PV panel in accordance with the position of the sun. The irrigation pump can be controlled in GSM mode. GSM mode the farmer at his own discretion can send a message to ON and OFF the water pump without actually going to the field
