The Advantages and Disadvantages of Solar Street Light
Advantages
1、Energy-saving: Solar street light generates electricity by absorbing solar power, which saves the electricity bill.
2、Safe: AC power supply lighting fixtures have safety risks due to various reasons such as construction quality, raw materials embrittlement and disorder of the power supply system. Solar street lights do not use AC current so there is no safety risk.
3、Environmentally-friendly: Solar street light causes no pollution and radiation, which conforms to modern low-carbon and environmental awareness.
4、Durable: The components of solar street light can keep good performance for ten years. And the solar panels can last for twenty-five years.
5、Low Maintenance Cost: In the remote area, the cost for power transmission and distribution is quite high. So, the cost for traditional street light is higher. Instead, solar street light only requires regular maintenance and save the utility electricity bills.
6、Easy Installation: To install a solar street light is easy and convenient. Customers can choose and adjust the size of solar street light based on their needs.
7、Independent Power Supply System: Off-grid solar street light system is freer and more independent in obtaining power.
Actually, it is known that the biggest advantage of solar street light is environmentally-friendly and energy-saving. It will be applied to China and the whole world. With the popularization of solar power, people will tend to reduce the use of other power. The application of solar power will make our world more beautiful.
Disadvantages
1、The project cost of solar street light is relatively high. The project cost of solar street light is higher than traditional street light because the components of solar street light include solar battery and solar panels. The solar street light requires huge investment which will bring economic pressure although the maintenance fee is low.
2、The solar street light may not work when there is no sunlight.
The working principle of solar street light is that solar panels convert sunlight into electricity. The electricity power is then stored in solar rechargeable batteries. The battery will supply power to the light at night. Solar street lights can not be applied to areas where there is insufficient sunlight. If solar street lights encounter continuous rainy days, the electricity will not be generated and the lights are unlikely to work.
3、The solar street light is likely to be stolen.
The components of solar street light are somewhat valuable. If the solar street lights are installed in the sparsely-populated area, the thieves will steal the components except lamp-post and then sell them to earn money.
In conclusion, solar street light can save the installation fee, project cost and electricity bills. Although it has some disadvantages, but the advantages of solar street light are more than traditional street light. We believe that the solar street light will be applied widely and become the ideal lighting system in both big cities and countries in the future.
