Solar Exhaust Fan Versatility - The solar fan comes with an 8.2 -foot extension cord and can be installed in greenhouses, chicken coops, sheds, dog houses, window vents, barns, cowsheds, treehouses, attics, and anywhere else, suitable for indoor and outdoor environments.
NOTE - Fan speed is greatly affected by sunlight. When the solar panels are exposed to direct sunlight, the fan speed can reach 3200 RPM. In weak sunlight, the fan will slow down or even stop running. Solar fans do not have a built-in battery and can only work during the day.
