Photovoltaic power generation is gradually becoming an important energy structure reform direction in various countries
In order to achieve the goal of carbon peaking and carbon neutrality, the development of new energy has been accelerated in an all-round way. Recently, the National Energy Administration issued the "Notice on the Development and Construction of Wind Power and Photovoltaic Power Generation in 2021". Increase year by year to ensure that non-fossil energy consumption accounts for about 20% of primary energy consumption in 2025. In the medium and long term, carbon peaking, carbon neutrality, and non-fossil energy will account for about 25% of primary energy consumption by 2030. The target is clear, and photovoltaics will play an important role in carbon emission reduction in the future. Important direction of energy structure reform.
Solar street light is a small independent solar photovoltaic power generation system, which consists of solar panels, energy storage devices, lamps, controllers, etc. Solar energy is provided by photoelectric conversion, and solar street lights are pollution-free, noise-free, radiation-free, environmentally friendly, and easy to install, bringing obvious and usable advantages to the construction of municipal projects.
Below we will briefly list a fewApplication cases of solar street lights in energy conservation, emission reduction and carbon neutrality.
1. Technical transformation of solar cells for street lamps in some sections of Yuhang District, Hangzhou
The urban management department of Yuhang District, Hangzhou has upgraded and transformed some street lamps. The CIGS ultra-thin flexible thin-film solar cell technology used on the surface of the street lamps is seamlessly bonded and perfectly matched with the pole body. Combined with grid-connected and off-grid energy storage technology, the pole body can be In wet, dusty, foggy and other conditions, it can generate electricity efficiently and become the core element of the entire rod body. At the same time, combined with the latest Internet of Things, big data and artificial intelligence technologies, it becomes a truly green and zero-energy block.
2. Ningbo's first modern urban carbon neutral comprehensive demonstration area
On June 11, Ningbo's first modern urban carbon-neutral comprehensive demonstration zone started construction in Wandi Village, Yinzhou District. It is understood that it is planned to build a modern urban comprehensive demonstration area of "carbon neutrality, bright service, digital intelligence, and rural revitalization" in 2 to 3 years. In order to build a modern urban carbon-neutral comprehensive demonstration area, more projects will be started here in the future. In the future, it is also planned to build street lamps with integrated light and storage in the demonstration area.
3. “One Belt, One Road” National Green Energy Saving Project
Countries co-constructing the Belt and Road Initiative have made some useful attempts in promoting green development through cooperation. For example, in the Sino-Egypt TEDA Suez Economic and Trade Cooperation Zone established in 2016, all the main roads in the 2-square-kilometer project in the first phase of the expansion area were installed with "wind energy + solar energy" street lights, becoming the first park in Egypt to use green energy street lights on a large scale.
In tropical countries, there is a large market for solar street lights. In addition, many African countries have introduced energy-saving and environmental protection programs in recent years. Project parties who contract government orders will look for Chinese suppliers on the international station. For more than ten years, solar street lights made in China have arrived in Africa across the ocean, absorbing solar radiation during the day and storing it as electrical energy, and discharging at night to illuminate the streets and campus dormitories in Africa.
