Firstly，How to choose a household wind turbine. Household wind turbines are devices that can generate electricity by utilizing wind energy. When choosing a home wind turbine, the following factors need to be considered : 1.Economic cost: The purchase and installation costs of household wind turbines need to be considered, generally not suitable for households with low electricity consumption. 2.Geographical environment: Household wind turbines need to be placed in sufficiently spacious and exposed areas to the wind, and it doesn't cause noise pollution to neighbors. 3.Daily electricity demand: When choosing a domestic wind turbine, it is necessary to consider the daily electricity demand of the household and the resulting electricity consumption. Secondly，Wattage requirements for household wind turbines Different households have different needs for electricity. Generally speaking, household wind turbines below 2000 watts can meet the daily electricity needs of most households. But if there are many household appliances used or if high-power appliances are frequently needed, then you need to consider buying more powerful household wind turbines. When considering the wattage demand of household wind turbines, we also need to pay attention to the following aspects: 1.Wind energy source: The output power of wind turbines is directly related to wind speed,The appropriate equipment needs to be selected according to the full degree of wind energy in the location. 2.Time: Wind energy has a time limit,so when choosing a household wind turbine,It is necessary to consider the average wind speed and household electricity time in the location to consider how much power to buy wind turbines. 3.Seasonal variation: Seasonal variations can also affect the output of wind turbines. To sum up，The wattage demand of household wind turbines is related to various factorssuch as the actual electricity demand of the household and the wind energy adequacy of the location.But what specific power of household wind turbines do you need to purchase,It also needs to be considered in light of the actual situation.

With the improvement of people's awareness of environmental protection and the wide application of renewable energy, we believe that many friends have seen wind turbines during their travels. Today, let us tell you the more details about vertical axis wind turbines. According to the principle of vertical axis wind turbine,The speed of the wind turbine increases rapidly，its power generation rising speed is correspondingly faster, and the power generation curve becomes full. Under the same power conditions, the rated wind speed of the vertical axis wind turbine is smaller than the horizontal axis wind turbine, and the vertical axis wind turbine generates a large amount of electricity when operating at low wind speed. From the mechanical analysis, the higher power of the vertical axis wind turbine, the the longer of the blades, the longer the distance between the center point of the parallel rod and the center point of the generator shaft,the worse the wind resistance ability, therefore, the triangular vector method can make up for some of the above shortcomings. In the structure, we use the design of straight blade and triangular double fulcrum for vertical axis wind turbines, and the main stress points are concentrated in the hub, which solves the problems of blade falling off, breaking and blade flying out. The blades of vertical axis wind turbine form a circle according to the same Angle difference, so the design purpose can reduce the pressure on the center support. In addition, a series of auxiliary equipment such as gear boxes, reduction boxes and transmission devices can be placed on the working platform relatively close to the ground, reducing the weight of the fan itself, reducing the construction and maintenance costs of the fan to a certain extent, and the vertical axis wind turbine can be used in building integration, which is conductive to urban construction. Therefore, the overall performance index is high. If you are interested in vertical axis wind turbines or have any questions, you can leave messages or private messages in the background.

Wind energy and solar energy as pure renewable green energy, more and more people pay attention to, the complementarities of the two in time and region make the wind-solar complementary power generation system has a good match in resources, wind-solar complementary power generation system is an independent power system with good resource conditions, and wind-solar complementary street light is a significant application of wind-solar complementary power generation system. The wind-solar complementary street light system is to change the grid power supply of traditional street lights into a wind-solar complementary power generation system that converts wind and solar energy into electricity. The system structure block diagram is shown in the figure. The system consists of wind generator set, solar photovoltaic array, rectifier circuit, voltage regulator circuit, unloader and energy-saving street lamp.The overall working principle of the system is as follows: the three-phase AC from the wind generator set is rectified after the DC and the DC from the photovoltaic array is charged after the voltage regulation circuit, and the battery supplies power to energy-saving street lights. From the perspective of power generation and consumption, the system mainly consists of four parts: power generation, power transformation control, power storage and power consumption. The power transfer is shown in the figure.
With the continuous improvement of China's road traffic network, some remote areas have also built roads, but the use of ordinary street lights in these areas requires the laying of special lines, which will consume a lot of manpower and material resources, so the characteristics of independent power supply of wind and solar complementary street lights are very suitable for use in these areas. The power supply of mobile communication base stations, the electricity consumption of remote mountain villages and the electricity consumption of border posts can all be solved by wind-solar complementary power generation technology, so the study of wind-solar complementary street lamps has wide significance.
