In recent years, with the double-carbon strategy taking root, the green energy industry is booming. As an important combination of new energy and lighting, solar lighting has gradually replaced traditional grid lighting with its core advantages of energy saving, environmental protection, convenience and zero energy consumption, and has been widely used in various scenes such as cities, villages and industrial parks, and has become an important force to promote the green transformation of outdoor lighting and help build a new energy system.

The continuous efforts at the policy level have built solid support for the development of the solar lighting industry. The "14th Five-Year Plan for Modern Energy System" jointly issued by the National Development and Reform Commission and the Energy Bureau clearly proposes to promote the deep integration of renewable energy such as solar energy with lighting, architecture and other fields, accelerate the energy-saving transformation of outdoor lighting, and promote solar lighting products. Various localities have also introduced supporting policies to increase support for solar lighting projects: promoting full coverage of solar lighting on rural roads in many places in the north to solve the lighting problems in remote villages; Southern cities incorporate solar lighting into the construction of smart cities and apply it to public areas such as parks, squares and pedestrian streets; By installing solar lighting, the industrial park can reduce the electricity cost of enterprises and help the construction of green factories. The data shows that up to now, the cumulative installation of solar lighting in China has exceeded 120 million lamps, covering more than 90% of administrative villages and 80% of industrial parks in the country, saving over 30 billion kWh of electricity and reducing carbon emissions by over 25 million tons.

The iterative upgrading of technology has made solar lighting get rid of the industry pain point of "insufficient brightness and unstable battery life", and its competitiveness has continued to improve. Nowadays, the photoelectric conversion efficiency of solar photovoltaic modules has been steadily improved, and the efficiency of monocrystalline silicon modules has exceeded 24%, which is nearly 5 percentage points higher than that of five years ago. With the continuous optimization of energy storage battery technology, the energy density and cycle life of lithium iron phosphate battery are greatly improved, which can realize stable lighting for 7-10 days in continuous rainy days, and completely solve the problem of solar lighting "depending on the weather". At the same time, with the integration of intelligent control technology, solar lighting has been intelligently upgraded, with functions such as light control, time control and remote control. Users can flexibly adjust the brightness and set the switching time through the mobile APP, and some high-end products also have functions such as fault alarm and energy consumption monitoring, which greatly reduces the operation and maintenance costs. In addition, the durability of the product is also significantly improved. The protective design of waterproof, lightning protection and high and low temperature resistance enables it to adapt to extreme environments in different regions, and its service life can reach 8-12 years.

With the continuous expansion of application scenarios, the value of solar lighting is fully released. In the field of rural revitalization, solar street lamps and solar courtyard lamps have solved the problems of insufficient power grid coverage and high lighting cost in remote rural areas, illuminated the villagers' travel routes, and also helped improve the rural living environment; In urban construction, solar landscape lights and solar projection lights are applied to parks, green spaces and urban landmarks, which not only save energy and protect the environment, but also add bright colors to urban night scenes and become the "landscape" of urban green development; In the industrial field, solar lighting is widely used in outdoor places such as mining areas, ports, logistics parks, etc., and it is convenient to install without laying cables, effectively reducing the operating costs of enterprises; In the field of emergency, portable solar lighting has become the first choice for emergency lighting in earthquake, flood and other disaster sites because of its advantages of flexible movement and independent power supply.

Industry experts said that the current solar lighting industry is in the golden period of rapid development. With the continuous innovation of technology and continuous support of policies, the industry will gradually transform into intelligence, scene and high-end. In the future, solar lighting will be further integrated with technologies such as energy storage and Internet of Things, and more application scenarios will be expanded, which will not only play an important role in outdoor lighting, but also gradually penetrate into indoor auxiliary lighting, emergency rescue and other fields, injecting more light power into green and low-carbon development. At the same time, the industry also needs to strengthen standardized management, solve the problems of virtual parameters and uneven quality control, and promote the high-quality development of solar lighting industry.
