Introduction:
Solar energy is the most abundant source of energy in the World. Solar
Power is not only an answer to today’s energy crisis but also an
environmental friendly form of energy.
Photovoltaic generation is an efficient approach for using the solar energy.
Solar powered irrigation system can be a suitable alternative for farmers in
the present state of energy crisis automatic irrigation system using solar
power which drives water pumps to pump water from bore well to a tank
and the outlet valve of tank is automatically regulated using controller and
moisture sensor to control the flow rate of water from the tank to the
irrigation field which optimizes the use of water.

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.
Submersible Pump:
This solar system contains a submersible pump, a water tank, an
irrigation pump, associated water pumps.
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.

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 depends 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.

Applications:
Agriculture livestock watering / crop irrigation, home gardens and drip
irrigation systems.
Domestic portable water for remote homes, campgrounds.
Pond water management and water transfer.
Water supply for villages in developing world.
equivalent voltage this is given to a sensing circuit which has a
reference voltage that can be adjusted by the farmer for setting different
moisture levels for different crops.
18. Advantages:-
Highly sensitive , low cost and reliable circuit.
Works according to the soil condition.
Complete elimination of manpower.
Can handle heavy loads up to 7A.
System can be switched into manual mode
whenever required.

19. Disadvantages:-
This is applicable for only large farms due to high
initial implementation cost.
Have limited life after installation due to the
detoriation of the plastic component in a hot ,
arid climate when exposed to ultraviolet light.

Conclusion:
By using the automatic irrigation system it optimizes the usage of water
by reducing wastage and reduce the human intervention for farmers
The excess energy produced using solar panels can also be given to the
grid with small modifications in the system circuit which can be a
source of the revenue of the farmer, thus encouraging farming in India
and same time giving a solution for energy crisis.
Solar pumps also offer clean solutions with no danger of borehole
contamination.
Solar Powered Auto Irrigation System is very helpful to Engineering
Students.
