How low light can the solar table fan operate normally?
Publish Time: 2024-12-05
The normal operation of a solar table fan depends on the intensity of light received by its solar panels. Generally speaking, solar table fans are designed to work efficiently under standard daylight conditions (usually sunlight on a sunny or cloudy day). However, they can also operate in lower light conditions, but with reduced efficiency.Light intensity and operation of solar table fanStandard daylight conditions: The intensity of direct or diffuse sunlight is typically around 1000-1200 watts per square meter (W/m²) on a sunny or cloudy day. Under these conditions, the solar table fan can operate efficiently, the battery panel can be charged quickly, and the fan can run continuously.Low light conditions: On cloudy days or indoors near windows, light intensity may drop to 100-500 watts/m2. Under such conditions, the solar table fan can still operate, but the charging speed will be significantly slowed down and the fan's running time will be shortened accordingly.Indoors, if the light intensity is lower than 100 watts/square meter, the solar table fan may not be able to charge properly and the fan will not be able to run continuously.Nighttime or Extremely Low Light Conditions: In total darkness, the solar table fan cannot be charged by the solar panel and therefore cannot operate.Design considerations for solar table fansBattery capacity: In order to operate under low-light conditions, some solar table fans are equipped with larger-capacity batteries, which can store more power when there is sufficient light for low-light or night use.Panel efficiency: High-efficiency solar panels convert electricity more efficiently at lower light intensities, allowing the table fan to run longer.Energy-saving design: Some solar table fans adopt energy-saving designs, such as low-power motors and intelligent control systems, to utilize power more efficiently under low-light conditions.The solar table fan can operate efficiently under standard daylight conditions, but can still operate under low light conditions (such as cloudy days or indoors), but the efficiency will be reduced. In a completely dark environment, the solar table fan cannot operate. In order to function normally under low light conditions, it is recommended to choose a solar table fan equipped with a large-capacity battery and a high-efficiency battery panel.
