Usage defects of solar street lamps

With the use of solar street lamp technology, solar street lamps have emerged in the market. However, in the actual research and application of LED street lamps, the inherent defects of solar LED street lamps cannot be avoided or overcome:
The first thing to bear is that in this system, which focuses on "energy conservation and environmental protection", there is a significant waste of resource allocation. Because street lighting products have mandatory standard requirements, including the "power failure rate" indicator, it does not allow them to stop working in rainy days, as landscape lighting products do. In this way, from a technical design perspective, the collection and storage of energy must be based on the most unfavorable climatic conditions (seasons with short sunshine periods, continuous overcast and rainy days, etc.). As a result, under most usage conditions, most energy configurations (solar cells) and power storage devices are idle, and not only is the system cost inevitably high, Moreover, it runs counter to the theme of energy conservation and comprehensive utilization that the system itself is intended to represent.
In addition, some seemingly simple technical problems need to be solved with relatively high cost investment in practical applications, including: First, the problem of centralized management. If electrical lines are not used, it is difficult to achieve centralized management and remote monitoring that are important for street lamps. However, if electrical lines are configured again, not only will the cost increase, but the significance of the product in terms of "selling point" be weakened; Secondly, the lifespan of solar cells, batteries, and other control components is often lower than the lifespan of LEDs, which leads to many problems that need to be solved to achieve the long lifespan of the entire system, and also leads to relatively high maintenance costs; Third, because the system uses DC batteries, it is very easy to be stolen, so theft prevention is also a major problem for the system. In addition, the weight issue of solar cells with relatively high installation heights can also increase the cost of improving the wind resistance of the lamp pole design, and these issues are issues that solar LED lighting systems cannot fundamentally solve.
Correspondingly, as the cost of LED products continues to decrease, the cost performance of LED street lamps using municipal power is continuously improving. Combining its core advantages in terms of life span, power saving, and other aspects, after stripping out high-cost solar systems, its one-time investment cost can be reduced to a level acceptable for market-oriented applications. With its advantages in the concept of "energy-saving" products and the promotion of relevant government departments, the pace of application has begun to move from "demonstration and promotion" to a true sense of "market promotion". With the subsequent progress of technology and improvement of standards, the prospect of widespread application is becoming increasingly clear.
In the foreseeable future, independent LED street lighting has become increasingly attractive, but the combined application of solar energy is no longer a hot spot.
Of course, to say that this technology is no longer a hot topic is not to say that it is meaningless or has no development prospects. On the one hand, the application advantages of solar LED lighting in some specific occasions (islands, scenic peaks, remote locations, etc.) are still obvious, including the positive significance of demonstration applications, so technical research is still very meaningful; On the other hand, in terms of landscape lighting (courtyard lights, lawn lights, etc.) and the application of centralized power supply within the regional network of solar energy systems that may be promoted in the future, its technology and market have great prospects for development.
