Solar street lights are a widely chosen lighting tool for many cities' illumination projects. They are primarily marketed for their energy-saving and environmental-friendly features, with minimal resource waste issues. However, from a technical standpoint, the collection and storage of energy require ideal climatic conditions. Not only do the system costs inevitably remain high, but they also conflict with the theme of energy-saving and comprehensive utilization that the system is supposed to embody.

Solar streetlights are becoming increasingly common, but their flaws and technical shortcomings in actual research and application are unavoidable and challenging to overcome.蓄电池in solar streetlights typically have an average lifespan of 500 charge-discharge cycles, making the initial investment for solar streetlights higher compared to traditional streetlights. Additionally, maintenance costs are significantly higher, requiring repairs or management approximately every year or six months, which can amount to about a third of the initial investment. Moreover, light source damage necessitates timely replacement. Therefore, simply installing the photovoltaic lighting system once after the completion of a solar streetlight project is not a one-time solution; ongoing maintenance is essential to ensure long-term illumination. Beyond this, seemingly simple technical issues also demand higher cost investments to be resolved in practice.

① Challenges with centralized management: It's difficult to achieve important centralized control and remote monitoring for solar street lights without electrical wiring, but adding electrical wiring not only increases costs but also diminishes the product's selling points.

The issue of solar street lamp batteries, battery life, and other control components typically having shorter lifespans than LEDs poses challenges in achieving a long lifespan for the entire system, and also results in higher maintenance costs.

③ Due to the use of DC batteries in the system, they are highly susceptible to theft, making anti-theft a significant issue. Additionally, the weight issue associated with installing solar panels at a higher height affects the wind resistance design of the lighting poles, which in turn increases costs. These and other issues are not fundamentally solvable by solar LED lighting systems.
