Abstract: Many people are using non renewable energy sources in high amount of their needs. Some Minerals are exhausting with the high usage, so it is obvious to depend on the renewable sources like solar & wind etc. In this paper a solar energy based water pump system with different time slots are proposed. The solar energy is converted into electrical energy by photovoltaic cells and it charges the battery. During Day time battery stores the energy. In this project AT89S52 microcontroller are used. For this microcontroller the program is written for giving different time slots. One 16*2 LCD display is using to see the status of system. For adjusting contract display one variable resistor called ‘preset’ is used. One sensor is used to observe the water level and to send data back to the microcontroller. The manual ON/OFF control of the system can be avoided with this sensor. This is a new method to operate motor / machine for a small duration. Buzzer gives a beep sound. A transistor is used to drive the relay during on time period; relay is used to control the pump. A switching diode is used to control the reverse EMF. The proposed system has the advantage of automatic switch off for the given time. This will be the one of best solutions for smart solar irrigation for farmers. In addition, this solar system controls the flow of water across the field.
