Here’s how you can build a solar-powered irrigation working model with a DC water pump, solar panel, water tank, and paper cups for plants.
Materials Needed:
Solar Panel (6V-9V, 1W-5W) (to power the pump)
DC Water Pump (3V-6V) (to lift water to the tank)
Plastic Bottle (Water Tank) (for storing water)
Paper Cups (to hold plants)
Tubes or Straws (for water flow)
Water Tank Stand (Cardboard or Plastic Pipe) (to hold the tank)
Switch & Wires (to control the pump)
Glue, Tape, Scissors (for assembly)
Steps to Build:
1. Set Up the Water Tank & Stand
- Cut a plastic bottle to make a water tank.
- Place it on a stand made from cardboard or plastic pipes to keep it elevated.
- Attach a small hole with a tube at the bottom to release water.
2. Install the DC Water Pump
- Place the DC water pump inside a small container filled with water (represents a well or reservoir).
- Connect a tube from the pump to the water tank so that the water can be lifted.
3. Connect the Solar Panel
- Connect the solar panel to the water pump using wires.
- Ensure the solar panel gets direct sunlight or a bright light source.
- Add a switch to control the flow of electricity.
4. Set Up Drip Irrigation
- Punch small holes in a tube or straw coming from the water tank.
- Place the tube over the paper cups (plants) so that water slowly drips to the roots.
How the Model Works:
The solar panel absorbs sunlight and generates electricity.
The DC pump lifts water from the reservoir to the water tank.
Water flows through tubes from the tank to the plants using gravity.
Drip irrigation provides water efficiently to plants in paper cups.
