I. The Magic of Converting Sunlight into Electricity

The core secret of solar-powered fans lies within the photovoltaic panels: When sunlight hits the silicon crystals, photons

act like small hammers, knocking out electrons, resulting in direct current. This process is similar to photosynthesis in plants,

except that it produces electrical energy instead of oxygen. A 20W photovoltaic panel can generate approximately 1A of

current on a sunny day, sufficient to power a small fan to operate continuously. 

II. The Wondrous Journey from Electrical Energy to Wind Energy

The generated current undergoes three transformations: 

Voltage stabilization treatment: The controller is used to prevent voltage fluctuations from damaging the motor. 

Energy storage: Excess electrical energy is stored in the battery for future use (for models with energy storage capability) 

Power conversion: The motor converts electrical energy into magnetic force, causing the fan blades to rotate at a speed of

800 to 1500 revolutions per minute. 

III. The Intelligence of the Green Fan

Compared to traditional fans, the solar-powered version possesses three survival strategies: 

Self-sufficient: With 4 hours of sunlight, it can operate for 8 hours. 

Smart sleep mode: Most models automatically enter standby mode when there is insufficient light. 

Module Design: The photovoltaic panel and the fan can be installed separately. It is suitable for special scenarios such as

outdoor camping and situations with insufficient power supply.
