Second, the technology is relatively simple problem, in the actual application also need to use a relatively high cost of investment to solve, including: first, centralized management of the problem, if you do not use electrical lines, it is difficult to achieve the street More important centralized management and remote monitoring, but if the re-allocation of electrical lines, not only increase the cost of the product in the "selling point" on the meaning and weakened; Second, the solar cell life, battery life and other control components often Are lower than the LED life of the problem, which brings the whole system to achieve the long life in fact also need to solve many problems, also will have a relatively high maintenance costs; third, because the system uses a DC battery, very easy to be stolen, So anti-theft is also a big problem with the system. In addition, there is a general installation of the height of the relatively high weight of solar cells to bring the design of the poles to improve the wind capacity
Will bring the cost increase, and so these problems are solar LED lighting system can not fundamentally solve the problem.
Finally, with the LED product costs continue to decrease, the use of electricity for the city of LED lights cost is increasing, combined with its life, energy saving and other aspects of the core advantages, stripped of high-cost solar energy system, the one-time investment costs Has been able to drop to the extent that marketability applications are acceptable. With the "energy saving" product concept and the advantages of the relevant government departments to promote the pace of application has begun from the "model to promote" to the true sense of the "marketing", follow the progress of technology, standards, extensive The prospect of the application is becoming clearer.
So, in the near future, solar energy may not disappear as the incandescent lamp, but it will not be fully popular. Yangzhou, as many street lamp manufacturers expected, LED lights are leading a revolution in the lighting industry, the 21st century is the era of LED.
Advantages of solar street lamps The main advantages include: ① energy saving, solar street lights is the use of natural natural light source, reducing the consumption of electricity; ② safe, commercial lighting lights may exist due to construction quality, material aging, power supply disorders and many other The cause of the security risks. And solar street lights do not use AC, the use of the battery to absorb solar energy, the low-voltage DC into light energy, there is no security risks; ③ environmental protection, solar street light pollution, no radiation, in line with modern green concept; ④ high-tech, solar The lamp is controlled by an intelligent controller, which can automatically adjust the brightness of the lamp according to the natural brightness of the sky within 1d and the brightness required by people in various environments. ⑤ Durable, the production technology of the vast majority of solar modules is sufficient to ensure that 10 More than the performance does not decline, solar modules can generate 25 years or longer; ⑥ maintenance costs are low, away from the remote areas of the town, in order to maintain or repair conventional power generation, transmission
