With the development of science and technology, some new energy and new products have gradually replaced traditional energy and old products. Just like the lights used in our households, from the previous kerosene lamps to the electric lights, until now, LED lights are more popular. LED lights are green and safe, is it possible to use it in addition to being used in the living room? Can it be extended to the outdoors as a street light?
In fact, many areas have already installed LED solar street lights. In some areas, people are still considering, street lamps are expensive equipment, and the price of solar street lamps is more expensive than the grid powered street lights. So is solar street lamp not worthy to use in large-scale?
On the contrary, although the price of solar street lamps is more expensive than the grid powered street lights, we still say it is more cost-effective. Why do we say this ? Let me explain it to you.
The initial investment cost of solar street lights will be higher than that of the city circuit lights. After all, whether it is solar energy or led, it is regarded as the result of the new era of science and technology. Naturally, it is more expensive than the traditional street lights that generate electricity. However, this is also limited to the initial stage. From the perspective of long-term development, solar street lights are more cost-effective than city circuit lights.
First of all, when installing solar street lights, there is no need to lay cable lines and dig through the channels, which saves a lot of manpower, material and financial resources.
Secondly, because there is no need to use cable, there will be no expensive electricity bills. Although the price of grid powered street lamp is cheaper than that of the solar street lamp, it will generate a high electricity bill during the process of use. Compared with the renewable solar energy, it is not conducive to the long-term stable development of urban and rural areas.
Finally, because solar street lights are not as complicated as the grid powered street lights and no redundant materials when installed, it naturally saves some of the subsequent maintenance costs.
It is worth mentioning that the service life of solar street lights is longer than that of grid powered street lights. The average service life of the grid powered street light is 10,000 hours, the solar panel service life of solar street lamps is 20 years, the battery life span up to 3-5 years, and the service life of LED lamps is 50,000 hours. From this point, the use of solar street lights is much more cost-effective than the grid powered street lights.
Solar street lights are not only safe and environment friendly, but also suitable for long-term development in terms of price.
