Which one is the most practical, solar street light or ordinary street light? This topic has always been controversial. It is said that which is good. According to the current situation, solar street lights are in full swing in the current market. For a time, many companies who want to install street lights do not hesitate to choose solar street lights. Is there really a substantial difference in the use of the users?
First, let's understand the cost problem between the two.
According to the 6-meter pole, a set of ordinary 6-meter street lights is equipped with a 20w LED lamp, and the cost is about 700 yuan (medium quality) with embedded parts.
The same set of 6-meter solar street lights, equipped with a 20w LED lamp, an 80Ah battery, an 80wp solar panel, an embedded part, and a controller, the total cost is about 1900 yuan (medium configuration , Medium quality).
It can be clearly seen that the price of solar street lamps is 1.7 times that of ordinary street lamps. Let's put the price aside for the time being, and then compare the service life of the two.
The service life of ordinary street lamps is determined by LED lamps, because the components of ordinary street lamps are nothing more than lamp poles and lamp caps. It can be said that no matter how bad the quality of the street lamp pole is, it will not be a problem for 15 years. The theoretical life of LED lamps is 100,000 hours, even if it can only be used for 50,000 hours, it will be safe and sound within 15 years.
The service life of solar street lights is not simply determined by the LED lamp holder, but the battery. Many battery manufacturers give a warranty of 3 years, and the longest service life is 5 years, which means that from installation to use after 5 years, The working capacity of the battery will be greatly reduced or completely lost. The cost of replacing a battery is at least about 500 yuan (including labor).
Seeing here, everyone should have a general understanding. These data are just to let everyone know some necessary knowledge. Don't follow blindly. As a solar street light manufacturer, we hope that more and more people use solar energy. Street lights are good, but whether it is out of sympathy or social interest, these issues still need to be made clear to everyone.
Personal suggestion, if the construction wiring is not too difficult, try to choose ordinary LED street lights, it can be said to be done once and for all. For areas like mountain villages or areas where it is inconvenient to dig trenches for wiring, solar street lights must be the first choice for lighting products.
