When considering purchasing a solar fan, it is important to look at the wattage and duration of the fan. This information will help you determine the performance of the fan and how long it can run for on a single charge. Here are some examples of wattage and duration for different models of solar fans:
1. Standing Fans: A standing solar fan with a wattage of 20W to 30W can provide up to 8 hours of runtime on a single charge. These fans are ideal for larger spaces and can move a lot of air, making them perfect for outdoor use.
2. Table Fans: A table solar fan with a wattage of 10W to 15W can provide up to 10 hours of runtime on a single charge. These fans are ideal for smaller spaces such as bedrooms and offices and are designed to be portable.

It is important to note that the duration of the fan will depend on the intensity of sunlight and the capacity of the battery. Therefore, it is recommended to ensure that the solar panel is placed in direct sunlight to maximize the charging capacity of the battery. Additionally, it is important to ensure that the battery is fully charged before using the fan to ensure maximum runtime.
In summary, when considering purchasing a solar fan, one should look at the wattage and duration of the fan. Standing fans with a wattage of 20W to 30W can provide up to 8 hours of runtime on a single charge. Table fans with a wattage of 10W to 15W can provide up to 10 hours of runtime on a single charge.
