Did You Know?
Over 250,000 solar water pumps have been installed in Indian villages, providing sustainable irrigation and drinking water solutions!
A solar-powered water pump can reduce irrigation costs by up to 60% compared to diesel or electric pumps!
How Does a Solar Water Pump Work?
A solar-powered water pump uses energy from the sun to operate. Here’s how it works:
Solar Panels Capture Sunlight – The solar panel absorbs sunlight and converts it into electricity.
Power is Sent to the Pump – The generated electricity powers a DC water pump.
Pump Moves Water – The pump draws water from a well, river, or tank and directs it to your garden or home.
Storage Option – If needed, a battery stores extra energy for cloudy days.
No electricity bills, no pollution—just free and clean energy!

Materials Required
Component | Description |
Solar Panel | Converts sunlight into electricity |
Water Pump | Moves water from the source |
Battery (Optional) | Stores excess power for later use |
Wires & Pipes | Connects the system |
Charge Controller | Prevents overcharging of the battery |
Step-by-Step Guide to Building the System
Step 1: Set Up the Solar Panel
Place the solar panel in a sunny spot.
Connect the positive and negative terminals to a charge controller.
Step 2: Connect the Water Pump
Attach the pump’s power wires to the solar panel or battery.
Secure the inlet pipe in a water source (e.g., tank or well).
Position the outlet pipe to direct water where needed.
Step 3: Test the System
Ensure the pump starts when the sunlight hits the panel.
Adjust the pipe direction for the best water flow.

Programming the Pump (for Automated Systems)
If you want the pump to work only when water is needed, use an Arduino or Raspberry Pi. Here’s a simple code for automation:
import RPi.GPIO as GPIO
import time
PUMP_PIN = 18 # Define the pump’s pin
GPIO.setmode(GPIO.BCM)
GPIO.setup(PUMP_PIN, GPIO.OUT)
def pump_on():
GPIO.output(PUMP_PIN, GPIO.HIGH)
print("Pump is ON")
def pump_off():
GPIO.output(PUMP_PIN, GPIO.LOW)
print("Pump is OFF")
while True:
pump_on()
time.sleep(10) # Pump runs for 10 seconds
pump_off()
time.sleep(20) # Wait before turning on againThis makes sure your pump doesn’t run 24/7, saving water and energy!
Troubleshooting Common Issues
1. Pump Not Working?
Check if the solar panel is receiving enough sunlight.
Ensure all wires are connected correctly.
2. Water Flow is Weak?
Check if the pipes are clogged.
Use a stronger water pump if needed.
3. No Water at Night?
Add a battery to store solar energy for night use.
