With the concept of green and low-carbon deeply rooted in people's hearts and the continuous breakthrough of photovoltaic technology, solar lamps are accelerating to penetrate various scenes in urban and rural areas, from rural trails to urban parks, from outdoor landscapes to emergency lighting. With the advantages of "zero electricity bill, easy installation and smarter", they have become an important force to promote infrastructure upgrading and practice the goal of "double carbon", which not only illuminates the way for people to travel, but also lights up a new journey of green development.

Recently, all 200 high-brightness solar street lamps in Shagang Village, Dagou Town, Yangdong District, Yangjiang City have been put into use. The bright lights have dispelled the darkness in the countryside at night and won wide praise from the villagers. It is reported that most of the original street lamps in Shagang Village can not be used normally due to the influence of typhoon and long service life, which brings great security risks to villagers' travel at night. The first secretary in Shagang village took the lead in the investigation and applied to the dispatching unit for help. The donated 200 solar street lamps completely solved this livelihood problem. Before the construction, the staff went deep into 13 natural villages to investigate one by one, formed an accurate demand list, and determined the installation points in strict accordance with the principle of "three priorities and two avoidance" to ensure full coverage of lighting; During the construction period, village cadres spontaneously formed a "supervision team" to check the construction quality throughout the whole process and realize "installation on the same day and lighting on the same day".

The reporter learned that the solar lamps put into use today have got rid of the shortcomings of traditional products, such as "short battery life and low brightness", and the technical upgrade has brought about all-round improvement. Since 2025, perovskite solar cell technology has made a major breakthrough, and the conversion efficiency in the laboratory has exceeded 25%. The application of flexible photovoltaic materials has expanded the installation scene, allowing solar lamps to adapt to irregular surfaces. Taking the street lamp installed in Shagang Village as an example, it adopts the dual intelligent control mode of "light control+time control", the illumination radius reaches 20 meters, and it can be continuously illuminated for more than 4 days in rainy days, which is expected to save more than 70,000 yuan for the village collective every year. At the same time, many products are equipped with AI algorithm and Internet of Things technology, which can intelligently perceive illumination and people flow, dynamically adjust brightness and illumination duration, and realize remote monitoring and predictive maintenance.

Driven by the rural revitalization strategy, solar lamps have become the "standard" for upgrading rural infrastructure. In addition to Shagang Village, Zhouwan Village in Mahe Town, Hanchuan City, and many villages in Shangshi Town, Suizhou City, etc. have completed the installation of solar street lamps. 86 and dozens of street lamps not only ensure the safety of villagers' travel at night, but also enrich the rural nightlife. The villagers are chatting and dancing in the square dance under the lights, and the rural fireworks are becoming more and more intense. According to the relevant data of the National Energy Administration, by the first half of 2025, the installed capacity of household photovoltaic in China was about 180 million kilowatts, and the total installed capacity of solar outdoor lamps had exceeded 180 million sets, among which rural road lighting became the core application scenario, accounting for 38% of the market share.

In urban scenes, the application of solar lamps is also expanding. From landscape lighting in the park square to road lighting in industrial parks, from customized lamps in wetland parks to multifunctional smart poles in smart cities, solar lamps are deeply integrated with technologies such as building integration photovoltaic, 5G and environmental monitoring, and become an important node in the construction of smart cities. The market evaluation in the first quarter of 2026 shows that the mainstream solar garden lamps have achieved IP67 protection, which can resist extreme environments such as salt fog, high and low temperature, strong wind, etc. Some products also support customization, adapt to different landscape styles, and greatly improve the installation convenience.

Industry experts said that the solar lighting industry is in a critical stage of transition from "scale expansion" to "quality upgrading", and the triple engines of technological innovation, policy support and market demand jointly drive the development of the industry. It is estimated that the market scale of solar outdoor lamps in China will reach 21.8 billion yuan in 2025, up 17.8% year-on-year. In the next 10 years, the compound annual growth rate of solar street lamps will exceed 14%, and the market scale is expected to reach 35 billion yuan in 2030. With the continuous cost reduction and technological breakthrough, solar lamps will be further popularized, which will not only provide more efficient and environmentally friendly lighting solutions for urban and rural areas, but also inject lasting power into the construction of green energy system and the realization of "double carbon" goals.

1. Priority is given to the core parameters: it is recommended to choose products with photovoltaic conversion efficiency of more than 20%, and the endurance in rainy days should meet its own use scenarios. Outdoor products should give priority to IP65 and above protection levels;

2. Precautions for installation: Overhead installation shall be carried out by personnel with special operation certificates, and outdoor metal lamp poles shall be well grounded to avoid being close to dangerous buildings and existing telephone poles;

3. Key points of daily maintenance: regularly clean the dust of photovoltaic panels to avoid blocking and affecting power generation efficiency, establish a normalized inspection mechanism, handle faults in time, and extend the service life of products.
