With “divine” functions, especially without consuming electricity, this type of solar fan immediately caused a fever in the market and was sought after by many people. Mr. Nguyen Hung – an employee of an electronics store in Ho Chi Minh City – said that at this point, the demand for cooling fans has begun to increase sharply, in which the solar fan line is the best-selling model. . As at the beginning of summer, his shop sold about 300 solar fans, at the peak of last year’s heat, he sold up to 800 units. Many fan models are having super cheap prices to attract buyers Similarly, Mr. Hoang Van Binh – an employee of an electrical appliance store in Thanh Xuan (Hanoi) – also said that in recent years, the price of electricity has tended to increase, people have the need to buy and use electricity. Use energy-saving appliances and take advantage of natural energy sources. Therefore, from May, customers looking to buy solar fans are busier. Currently, he only has 15 more fans to sell out. According to him, this type of fan is often suitable for low-rise houses, level 4 houses rather than high-rise buildings and apartments like in the city. Because the fan and solar panels are separate, it is necessary to choose a location to mount the panels to catch the sun (roof, rooftop, balcony, front yard, …) then connect to the fan set. Therefore, with high-rise buildings, moving equipment is quite difficult. But Binh also admitted, when it rains, the charging capacity of the fan will be poor, so in the prolonged rainy season solar fans will not be able to promote their full benefits. At that time, the fan can still be used by the grid as usual. Talk to PV. VietNamNet, Mr. Le Van Kien – a technical staff member of an electrical appliance store in Khuat Duy Tien (Thanh Xuan, Hanoi) – shared, when buying a solar fan, it is necessary to pay attention to the lifespan of the panels. The origin of the battery is unclear, poor quality will make the fan’s performance worse, the fan runs erratically, the lifespan is reduced, and it pollutes the environment. Moreover, the life of the battery is usually only 2-3 years, then it has to be replaced at a considerable cost. In addition, the capacity of the battery will determine the operating time of the fan, the battery is designed with a high capacity, the better the charge will be and vice versa. Limit the selection of multi-function rechargeable fans that are equipped with lights, alarms or clocks… because these features consume power from large batteries, making it easier for the battery to fail faster. Users should not be greedy, but buying low-quality fans will have many potential risks, so consider when choosing and need to choose to buy products of reputable brands and addresses.
