A Solar Powered Pesticide Sprayer is an eco-friendly agricultural device that uses solar energy to operate a pesticide spraying pump, eliminating the need for manual pumping or fossil fuel-based sprayers. The system consists of a solar panel that charges a battery, which in turn powers a DC motor-driven pump to spray pesticides, herbicides, or fertilizers.

This technology reduces farmer fatigue, ensures consistent spraying pressure, and lowers operational costs while being environmentally sustainable. It is ideal for small to medium-scale farms and can be used for spraying crops, orchards, and plantations.

Parts Used:

1. Solar Panel – converts sunlight into electrical energy
2. Charge Controller – regulates voltage/current to protect the battery
3. Battery (Li-ion or Lead-acid) – stores solar power for continuous operation
4. DC Motor Pump – delivers liquid pesticide at constant pressure
5. Spray Tank – holds pesticide or liquid to be sprayed
6. Spray Nozzles – ensures uniform spray distribution
7. Pressure Regulator – maintains consistent output pressure
8. PVC Pipes & Hoses – for liquid flow
9. On/Off Switch – controls pump operation
10. Trolley or Backpack Frame – for portability
