A Solar Operated Air Cooler is an eco-friendly cooling device that uses solar power to run its fan and water circulation pump. It works on the evaporative cooling principle, where hot air is drawn through wet cooling pads, reducing its temperature before blowing it into the room. By using solar panels as the main power source, this system significantly reduces electricity costs and can be used even in off-grid areas.

This setup is ideal for rural homes, small shops, outdoor events, and locations with frequent power cuts.

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 energy for use when sunlight is low
4. DC Fan / Blower – circulates cooled air into the room
5. Water Pump (DC) – pumps water over cooling pads
6. Cooling Pads (Honeycomb/Grass) – provide large surface area for evaporation
7. Water Tank – stores water for continuous circulation
8. Frame & Enclosure – supports and houses all components
9. Pipes & Valves – direct water flow to pads
10. Wiring & Switches – control fan and pump operation
