As ordinary street lights require utility power supply, the low voltage transmission lines generally used are very long, which not only increases the power consumption of street lights, but also wastes electricity. These problems can be solved if wind and solar complementary street lights are used, so what is the meaning of wind and solar complementary? What is wind-solar complementary street light?

First, what is the meaning of wind and solar complementary
Wind-solar complementary is a new technology that utilizes solar cells and wind turbines to generate electricity, converting wind and solar energy into electricity, which is stored by batteries and then used for lighting. In many areas of China, wind and solar energy vary greatly with the seasons and are unevenly distributed in time and space. In summer, solar radiation is strong and solar energy resources are abundant; in winter, wind speed is high and wind energy resources are abundant. The use of a single wind or solar power generation is often insufficient to supply power in some months.
Wind and photovoltaic complementary technology makes use of the seasonal complementary characteristics of these two resources, and synthesizes solar cells and wind turbines into one system, which can give full play to its characteristics and advantages, maximize the use of solar and wind energy, thus overcoming the defects of power supply imbalance caused by seasonal changes in wind and solar energy, ensuring a balanced supply of power throughout the year, and making full use of natural resources. Wind power and solar photovoltaic power generation complementary lighting system provides a higher level of reliability.
Second, what is the wind and solar hybrid power plant
Wind and solar complementary power station, also known as distributed wind and solar complementary power station, using wind and solar complementary power generation system. Wind and solar complementary power station system mainly consists of wind turbine generator, solar battery array, intelligent controller, battery pack, multi-function inverter, cable, bracket and auxiliary components, the power will be connected to the conventional power grid. Wind power is utilized to generate electricity at night and on cloudy and rainy days when there is no sunlight, while solar power is utilized on sunny days.
With wind and sun working at the same time, it realizes the function of all-weather power generation, which is more economical, scientific and practical than using wind turbine and solar energy alone. Applicable to road lighting, agriculture, animal husbandry, planting, breeding, tourism, advertising, service industry, ports, mountains, forest areas, railroads, oil, military border stations, communication relay stations, highway and railroad signal stations, geological exploration and field survey workstations and other places where electricity is inconvenient.
Third, what is the wind-scope complementary street light
Wind and light complementary street light refers to the wind and light energy complementary street light. Light energy refers to the solar panel to receive sunlight and convert it into electricity. Wind energy refers to adding a fan (with power size) on the top of the light pole. When it is windy, wind energy is generated and converted into electrical energy. The converted electricity is stored in batteries and automatically lights up at night when it gets dark.

Fourth, the advantages of wind and solar hybrid street lights
environmental protection and energy saving: wind and solar hybrid street lights through the wind and solar energy to generate electricity, do not need to rely on traditional fossil fuels, thus reducing greenhouse gas emissions and the impact on the environment. It not only saves energy, but also helps to reduce carbon footprint.

Renewable Energy: Wind and solar energy are renewable sources of energy that do not run out and are not affected by fluctuations in energy prices. Using these energy sources to supply power helps to improve energy sustainability and reduce dependence on limited resources.
independent power supply: wind and solar hybrid street lights do not need to be connected to the traditional power grid because they can generate the required power on their own. This allows the streetlights to be independently powered and work even in remote areas or where there is no power supply.
reduce operation and maintenance costs: operating and maintaining traditional street lights usually involves the maintenance and repair of power lines, while wind and solar hybrid street lights have lower maintenance costs after the equipment is installed. They do not require regular electricity expenses, reducing energy costs.
increase urban aesthetics: the design of wind-solar hybrid street lights is usually more creative than traditional street lights, which can add a bright landscape to the urban landscape. Their design can be personalized according to the characteristics and needs of the region.
respond to disasters: in natural disasters or other emergencies, the traditional power supply may be interrupted, while the wind and solar hybrid street lights can continue to work to ensure the basic lighting and safety of the city.
As one of the series products of new energy application, wind-solar hybrid street light is recognized and accepted by more and more people for its incomparable advantages. Wind-solar complementary street light is not only a kind of landscape, but also the best life teaching material for the application of new energy and renewable energy knowledge. Promoting wind-solar complementary street light has good social and economic benefits.
The principle of wind-solar hybrid street lights is to use solar and wind energy to generate electricity, store electrical energy, and power the light source with batteries at night. Its advantage in places with sufficient wind and insufficient light is extremely prominent. Are wind-solar street lights really better than solar street lights? The following lighting gives you a specific analysis.
The advantages of wind-solar hybrid street lamps mainly include the following aspects:
. It is undoubtedly a good solution to make up for the lack of sunshine. Especially in mountainous areas, where there are many trees, solar panels cannot get good sunlight in many cases, but the wind in mountainous areas is very stable and strong, so many people choose wind-solar hybrid street lamps as their main lighting tools. In coastal areas and rainy areas, solar panels often cannot get enough sunlight to supply power, and wind-solar hybrid street lights have their advantages.
. If a place has good continuous wind, the wind turbine can continue to generate electricity at night, so that the battery power consumed at night is very small, so that a battery with a smaller capacity can be used, thereby reducing the wind and solar hybrid street lights cost.
But not all areas are suitable for wind-solar complementary street lights. If a place has insufficient wind, or the monsoon climate is obvious, half or less than half of the year has a suitable wind speed, then the use of wind turbines can only increase solar energy The cost of street lights does not play a significant role. Therefore, before using wind-solar hybrid street lights, it should be determined according to the local situation and the specific conditions should be analyzed in detail.
