solar power automatic irrigation system ppt
In the field of agriculture, use of proper method of irrigation is important because the main reason is the lack of rains & scarcity of land reservoir water. The continuous extraction of water from earth is reducing the water level due to which lot of land is coming slowly in the zones of un-irrigated land.
Another very important reason of this is due to unplanned use of water due to which a significant amount of water goes waste. For this purpose; we use this automatic plant irrigation system. The system derives power from solar energy through photo-voltaic cells. Hence, dependency on erratic commercial power is not required.
In this project we use solar energy which is used to operate the irrigation pump. The circuit comprises of sensor parts built using op-amp IC. Op-amp’s are configured here as a comparator. Two stiff copper wires are inserted in the soil to sense whether the soil is wet or dry.
A microcontroller is used to control the whole system by monitoring the sensors and when sensors sense dry condition of soil, then the microcontroller will send command to relay driver IC the contacts of which are used to switch on the motor and it will switch off the motor when the soil is in wet condition.
The microcontroller does the above job as it receives the signal from the sensors through the output of the comparator, and these signals operate under the control of software which is stored in ROM of the microcontroller. The condition of the pump i.e., ON/OFF is displayed on a 16X2 LCD which is interfaced to the microcontroller.
Further the project can be enhanced by interfacing it with a GSM modem to gain control over the switching operation of the motor.
In recent days, agriculture field farmers are facing many problems in watering their plants to keep their crops green in summer season. It’s because they don’t have correct idea about the availability of the power. Even if the power is available, they have to wait until the pitch is properly watered. Thus this process restricts them to stop doing other deeds. But, there is a solution, i.e., automatic solar submersible pump control panel for irrigation. In the trial of solar based plant irrigation using submersible pumps, PV cells are used to generate electricity, which is stored in rechargeable batteries. These batteries produce power for the system operation. A submersible pump controller is used to pump a water from a boor well to a storage water tank. Then, the water is drawn by a submersible pump at the slope’s toe, where the installed sprinklers water the crops or plants.
Automatic Solar Submersible Pump Control for Irrigation
These systems work in the sunlight. When sun shines the water pumping process is a sensible way of solar electric power utilization throughout the summer, as the water necessity is the highest. These pumps provide a reliable water source for plantation. For any solar based pumping system, the capacity to drive water is a function of three variable such as power, flow and pressure.
Solar Panel
These panels are designed with solar cells composed of semiconductor materials. The main function of Solar panels is to convert solar energy into DC electrical energy generally of 12V, which is further used for the rest of the circuit. The number of cells required and their size depends on the rating of the load. The collection of solar cells can produce maximum electricity.But, the solar panel must place exactly at right angles to the sun rays.
The Source
Water sources are available in the form of springs, drilled wells, rivers, ponds, etc.
The Submersible Pump
This solar system contains a submersible pump, a water tank, an irrigation pump, associated water pumps. In the site trial, the submersible pump is kept in a stainless steel case, which is placed in a well pit at the junction of the open channel and the natural stream course. The pump controller pumps water to the water tank at a particular time period as set in the control unit. This system is designed with 450W of power, which is capable of pumping 2000 liters of water within 60 minutes. This power capacity takes into account the height difference between the water tank and the solar submersible pump.
The PV Panels
The photo voltaic cells depend on the size of the pump. A panel is esteemed in watts of power it can produce. This solar submersible pumping system should be operated with a PV array of capacity in the range of 200 to 500 watts peak, and measured under some standard test conditions. A plenty of modules in series & parallel could be used to get the necessary PV power array power o/p. The o/p power of the PV modules which are used in the PV array under standard test conditions should be a min of 74 watts peak.
Charge Controller
A solar charge controller is very important device in any solar-power system. It is used to maintain proper charging voltages of the batteries. The charge controller controls current and voltage from the solar panel and charges the battery, and also stops the charging of the battery from over and undercharging conditions.
Battery
The Battery is an electric device, that is used to store current which is produced from the solar panel and supplied to the corresponding loads. The number of batteries required depend on the load requirement.
Inverter
The main function of the inverter is that it converts the battery’s voltage to AC voltage in order to activate then loads. Therefore, it helps us to run many electronic devices, home appliances and computers. There are numerous types of inverters available in the market today.The characteristics of typical inverters include high switching frequency, high conversion frequency and less harmonic content, and so on.
