For the sake of applying the new energy and making the street lighting available to remote areas, the street lights keep developing. Solar street lights are the new trend, and later people developed all-in-one solar street lights. Traditional LED street lights have a cheap price; solar street lights can save energy; и all-in-one solar street lights can additionally save on installation costs. Then which one on earth is the most economically friendly street light? В этом отрывке, we will compare the solar street light price and costs of installation, электричество, and maintenance for these three types of lights. Давайте перейдем к этому!
Introduction of traditional, solar, and all-in-one solar street lights
The traditional white LED street light has a luminous efficiency as high as 80 лм/Вт, so it can save 50% к 60% of the energy consumption of the high-pressure sodium lights. Более того, these LED lights can work for 10 годы, таким образом saving on replacement and maintenance costs.
Solar LED street lights add солнечные панели, special батарейки, and other components on the basis of traditional street lights. В настоящий момент, the solar street light price is relatively expensive, which is about 3 times that of general street lights, but its late maintenance cost is low. Because the solar street light adopts distributed circuit control, the switch and energy conversion of the street light are all intelligently controlled without manual operation, so the maintenance cost is reduced.
The integrated lamp head (солнечная панель, controller, литиевая батарейка, and light source) is easy to install and maintain. Trench digging and wiring are not required for these street lights; однако, the light pole must be erected on the embedded portion (concrete foundation).
Prices of solar, all-in-one solar, and traditional street lights
The new LED technology makes the price of traditional LED street lights higher than that of the old high pressure sodium street lights. The price of a whole set of HPS street lights is normally $150-250, while that of LED street lights is around $400-700. The reason is that these two have totally different principles for producing electricity, and LED street lights use materials of better quality.
In order to make use of the solar energy and solve the problem of electricity shortages, solar lights have more high-tech components, such as the solar panels and the batteries. Поэтому, the solar street light price is relatively higher than that of LED street lights, which can be three times more expensive.
As for all-in-one solar street lights, due to their all-in-one design, panel power and battery capacitors are generally relatively small, and the cost is relatively lower than solar street lights. Кроме, it saves the cost of installing and fixing the panel bracket, the cost of the battery box, и так далее. Most of their applications are in places where the lighting requirements are not too high.
Costs of installation
Two main aspects of the installation costs for the traditional street lights are the costs of transformers and cables. С, for the same brightness, LEDs need less power than HPS street lights, their cable load flow will also be lower. This means that the cross-sectional area of a copper cable is small, and the smaller this area, the cheaper it will be. The cables for LED street lights can be 10 times cheaper than HPS street lights. As for the transformers, LED street lights will also need fewer of them than HPS street lights, saving 60% of the costs.
Things will be a lot easier with solar уличные фонари. The costs of installation for them can only include the construction of the base and the wages for the workers to install and test the lights. For other items like digging, pipelines, кабели, transformers, и так далее, the costs will be zero.
The integrated solar street lamp device is simple and does not require laying cables. The only thing to do to install the all-in-one solar lights is to make a cement base and then fix the lights with stainless screws. Compared with ordinary solar street lights, it also does not need to dig holes to bury batteries, saving installation costs.
Costs of electricity
Traditional street lights
When the other conditions are the same, the cost of electricity is totally determined by the power. So the power bill of the traditional HPS lights will be 2-3 times more expensive than that of the LED street lights. This cost is the product of the power, working hours, number of lights, and the cost per kilowatt-hour.
Solar street lights & All-in-one solar street lights
The costs of electricity will be zero as they obtain the power from the sunlight.
Costs of обслуживание
The cost of maintenance is related to the lifespan of the lights. Для traditional светодиодные уличные фонари, the good ones can have a service life of 10 годы. But once it breaks down, normally you will need to buy a new lamp, because there are many standards of the LED lights. It is a large part of the maintenance costs. Still, it costs much less than HPS lights because the lifespan of some HPS lights is only one year. Besides changing the lamp, you will also need to consider the costs of maintaining the cables and other equipment.
The lifespan of the batteries largely determines the cost of maintenance for solar уличные фонари. The batteries have a shelf life, and once they expire, their performance will not be as good as before. Changing a battery may cost you $50-100, depending on what types of batteries you have.
If the all-in-one solar street lights are not working, you don’t need to buy an entire new one. You can check the components of the light and figure out where the problem is.
Are solar street lights worth it?
Even though the solar street light is expensive at the beginning, it will save the power bill for you. For maintenance, sometimes you will only need to change the batteries. Their function of lighting up the streets with sunlight is what makes them worthy. If you cannot afford it, you can choose LED street lights. They are energy-saving, долгоиграющий, and more familiar to most people.
Выводы
The solar street light price is more expensive than that of traditional street lights, but it will save on the costs of running, установка, and maintaining the lights. If the solar street lights work well, their total costs will be lower than those of traditional street lights. But LED street lights are also a good choice since the technology is more mature. You can find LED street lights of the highest quality at Mokolight, the best Chinese LED light manufacturer with an experience of more than 17 годы. The LED lights with the most competitive prices are the best choice for your street lights!
