Solar fans are smarter and more energy-efficient

As people pursue environmental awareness, solar fans have become the best choice for people. Why are solar fans so popular? What are the specific advantages that attract people to choose them? What is the difference between it and traditional fans? There are many types of solar fans on the market, and many people don’t know how to choose. The following content will share with you the relevant issues of solar fans.

How does a solar fan work?

A solar electric fan is a device that converts solar energy into electrical energy and drives the motor to work. The specific working principle is as follows:

Solar panels: A solar electric fan is equipped with a solar panel inside, which consists of multiple solar cells. When sunlight shines on the panel, the light energy is absorbed by the panel and converted into DC power.

DC power storage: The DC power generated by the solar panel needs to be stored so that it can continue to work at night or on cloudy days when it cannot receive sunlight. Usually, a solar electric fan is equipped with an energy storage device, such as a lithium battery, to store electricity.

Inverter: Since the electricity generated by the solar panel is DC power, and the motor usually requires AC power to work, it is necessary to convert DC power into AC power. An inverter is an electronic component that can convert DC power into AC power and is usually embedded in the control circuit of a solar electric fan.

Motor: After the inverter converts DC power into AC power, it will be supplied to the motor of the electric fan. After the motor receives the power, it will generate wind by rotating the blades.

In summary, the working principle of the solar electric fan is to convert sunlight into DC power through solar panels, convert DC power into AC power through inverters, and finally supply it to the motor to drive the blades to rotate and generate wind.

Do solar fans really work?

Solar fans can be a good choice in some cases, but their effectiveness depends on a few factors:

Environmentally friendly: Solar fans use free, renewable energy and do not produce emissions, helping to reduce your carbon footprint.

Low running costs: Apart from occasional maintenance, there is almost no additional cost.

Portability: Many solar fans are small and easy to carry, suitable for use in places without power, such as camping, picnics, or during power outages.

How long can a solar fan last?

The operating time of a solar fan depends on the size and charging time of the solar panel, as well as the power and usage time of the fan. Generally speaking, after a full charge, a solar fan can be used continuously for about 4-8 hours.

Solar fans convert solar energy into electricity through solar panels and then store electricity through built-in batteries to drive the motor to operate, achieving the effect of a fan. Therefore, the size of the solar panel and the charging time directly affect the fan's operating time. At the same time, the power and operating time of the fan is also one of the influencing factors. Generally speaking, the power of a solar fan is between 3-10W, and the operating time is also about 4-8 hours.

What is the difference between a solar fan and a regular fan?

The main difference between a solar fan and a regular fan is how they are powered:

Solar fan:

• Use solar panels to convert sunlight into electricity.
• Usually used outdoors, such as on a terrace, garden, or camping site.
• No socket required, energy-saving and environmentally friendly.
• Reliant on sunlight, may not work on cloudy days or at night.

Regular fan:

• Use a socket to connect to the power supply.
• Usually used indoors, but there are also outdoor electric fans.
• The power is usually higher and the wind volume is larger.
• Can be used at any time, regardless of weather.
• Requires electricity consumption, which will incur electricity bills.

Which solar fan is the best?

It is recommended to use an ITEHIL solar fan, which is portable and can be taken to any place, such as a workshop, garage, camping trip, fishing, exploration, etc. It is very convenient and practical. At the same time, there are 4 wind speeds to choose from. You can adjust the wind speed according to the temperature of different environments so that you can enjoy the unlimited cooling provided by solar energy anytime and anywhere.

ITEHIL portable solar fan is affordable and popular among people. It can be powered by solar energy for 14 hours, and it can be extended to 10 hours if an AC power plug is used. You don’t have to worry about the weather because the ITEHIL portable solar fan can always accompany you. Therefore, the ITEHIL portable solar fan is your first choice.

What should I look out for when choosing a solar fan?

When choosing a solar fan, there are a few key factors to look out for:

Panel size and efficiency:

• Size: Larger panels absorb more sunlight and provide more power.
• Efficiency: Highly efficient panels convert more sunlight into electricity and provide stronger wind.
• Angle adjustment: The panels of some solar fans can be angled to maximize solar absorption.

Wind force and gear:

• Wind force: Choose the right wind force for your needs.
• Gear: Multiple gears can adjust the wind force to meet the needs of different situations.

Battery capacity:

• Capacity: The battery capacity determines how long the fan can run without sunlight.
• Charging time: Understand the battery charging time so you can schedule your use time.

Durability and waterproof rating:

• Material: Choose a fan with durable, non-damaged materials.
• Waterproof rating: If you need to use it outdoors, choose a solar fan with a waterproof rating.

Brand and after-sales service:

• Brand: Choose a reputable brand with reliable product quality.
• After-sales service: Understand the after-sales service policy so that you can get repairs in time when needed.
