No solar fan is required, just purchase a multifunctional solar power supply.
The battery panel is placed in a place where the sun can shine and is connected to the multifunctional power supply of the nest with a cable. Use the 220V AC output port of the power supply directly. connect a regular fan.
The specific power and cost depend on the usage time and power of the fan
How much electricity can a solar fan generate per second
The small fan on the head of the new energy-saving street light is in fact used to dissipate heat from the solar panels. Solar panels are an important part of new energy-saving street lights. They absorb sunlight and convert it into electrical energy to provide lighting energy for street lights. However, solar panels generatecertain amount of heat during their operation. If the heat cannot be dissipated in time, the working efficiency and service life of solar panels will be affected.
Therefore, in order to solve this problem, designers installed small fans on the heads of the new energy-saving street lights. This small fan can generate airflow through its own rotation, drawing heat away from the solar panel, thereby dissipating heat. In this way, the temperature of the solar panel can be effectively reduced and maintained within a suitable operating temperature range.
The design of the small fan is also very clever. It generally uses lightweight and efficient DC motors with low power consumption and low noise. At the same time, the blades of the small fan have also been optimized to improve the wind intensity and dissipation effect.thermal ion. In addition, the small fan is also dustproof and waterproof to cope with various harsh outdoor environments.
By installing small fans, new energy-saving street lights can better protect solar panels and improve their efficiency and lifespan. At the same time, the energy-saving design of the small fan also conforms to the concept of energy saving and environmental protection, thereby reducing energy waste. Therefore, the existence of small fans not only serves to dissipate heat from solar panels, but also improves the performance and reliability of the entire street lighting system.
In short, the small fan on the head of the new energy-saving street light is used to dissipate heat from the solar panel. It generates a flow of air to remove heat from the solar panels and keep them cool.within an appropriate operating temperature range. The small fan is cleverly designed and has energy-saving, dust-proof, waterproof and other functions, which improves the performance and reliability of the entire street lighting system.
I want to make a solar powered fan and use a regular 3V motor. I wonder if I can use a battery in the middle to charge it before using it and it will be able to be used
It mainly depends on the photovoltaic panels of the solar fan. How big is it, is it monocrystalline or polycrystalline, and where is it placed? Generally, the solar fan is equipped with a 15W board after generating electricity. , it charges the battery, stores the energy, then discharges the battery to work.
15W*1 hour*0.7=10.5WH is equivalent to generating 0.0105 kilowatt hours of electricity in one hour and 0.0000029166 kilowatt hoursof electricity in one second, which represents a negligible amount of electricity.
The design is quite reasonable. Go to Taobao to buy solar cells that can power your fan motor for a day (the bigger, the better), then connect according to the voltage of your fan, then pass a diode with a large enough current ( not used by some solar panels) and a battery with a voltage consistent with your fan (the bigger the better, at least enough for nighttime use) and then connect it to the fan. Come on, OK!
