A Solar-Powered Seed Sprayer is an eco-friendly agricultural device designed to spray seeds efficiently across a field using renewable solar energy. The system uses solar panels to power a motor-driven spraying mechanism that evenly distributes seeds, reducing manual effort and saving time for farmers. It can also be adapted to spray fertilizers or pesticides, making it a versatile farming tool.

By using solar energy, the device eliminates the need for fuel or grid electricity, making it highly beneficial for rural and off-grid farming operations.

Parts Used:

1. Solar Panel – converts sunlight into DC electricity
2. Charge Controller – regulates voltage/current and protects the battery
3. Battery (Lead-Acid / Li-ion) – stores solar power for continuous operation
4. DC Motor – drives the seed spraying mechanism
5. Seed Hopper – holds the seeds before spraying
6. Spray Dispenser Mechanism – controls seed flow and spreads them evenly
7. Frame & Wheels – for mobility across the farm
8. Switches & Wiring – to control the motor operation
9. Optional: Nozzle system for fertilizer/pesticide spraying
