We can see street lights everywhere in our daily life. They illuminates the parks, streets, roads, highways, etc. The most common types are traditional street lights and solar road lights. Solar road lights have obtained more popularity these years. The cost of non-renewable energy sources is still rising and new breakthrough of solar road light technology make some people turn to solar road lights from traditional street lights. It's confusing for some people to know the difference between solar road lights and conventional street lights. We will guide you to know the differences in this paper.
Scope of application
Solar road lights are suitable for areas where power resources are scarce. Some areas are affected by factors such as environment and construction difficulties. It is more difficult to install conventional street lights. Solar road light is a better choice. There are also some rural areas and highway central isolation areas, exposed to factors such as sun exposure, thunderstorms and electric shocks, which can easily cause damage to the lamps or excessive aging of the wires and cause short circuits. If you install traditional street lights, you need to dig holes and bury the wires, which is more troublesome. Similarly, in areas with sufficient electric energy resources and convenient line connections, both conventional street lights and solar road lights can be selected.
2. Installation comparison
The installation of conventional street lamp is complicated: there are complicated operating procedures in general lighting street lamp projects. First, cables must be laid. Here, a large number of basic works such as excavation of cable trenches, laying of concealed pipes, threading in the pipes, and backfilling must be carried out. Then carry out a long-term installation and debugging, if any of the lines has a problem, a large area of rework is required. In addition, the terrain and lines are complex, and the labor and auxiliary materials are costly. Solar road lights are easy to install. When installing, there is no need to lay complicated lines, just make a cement base and fix it with stainless steel screws.
3. Cost comparison
Street lighting project managers are always trying to lower the cost such as the installation, maintenance, electricity bills. Solar road light is a great option for them. It's easy to install compared with conventional street lights. No need to lay cables, trench holes, etc. Cost of manpower and material resources can be saved. After installation, solar road lights need almost no maintenance. The high electricity bills of conventional street lights and the complicated wiring require long-term uninterrupted maintenance. Especially in the case of unstable voltage, it is inevitable that the sodium lamp is fragile, and with the extension of the age, the aging of the line and the maintenance cost increase year by year. Electricity can be a huge cost of street lighting. Using solar road lights, no electricity bills will be generated. The cost will be recovered in 5-6 years, and more than 1 million electricity and maintenance costs will be saved in the next 3-4 years.
4. Safety comparison
Solar streetlights use 12-24V low voltage, stable voltage, reliable operation, and no hidden dangers, they are ideal products for ecological communities and road administration departments. The conventional street lamps have high potential safety hazards, and road reconstruction, landscape engineering construction, and the cross construction of water and gas pipelines will all affect the installation of conventional street lamps.
5. Environmental protection comparison
The solar road light is pollution-free and non-radiation, which conforms to the modern green environmental protection concept. By directly absorbing solar light, the sunlight is converted into electric energy and stored in the battery. In the evening, the electricity will be used to power up the solar road light under the command of controller. Solar energy is clean and environmentally friendly. Unlike conventional street lights, the electricity comes from fossil fules such as coal, oil.
6. Lifespan comparison
The lifespan of solar road lights is much longer than that of ordinary street lights, such as the main component of solar lamps-solar battery components have a lifespan of 25 years; low-pressure sodium lamps have an average lifespan of 18,000 hours; low-pressure three-color energy-saving lamps have an average lifespan of 6,000 hours; The average life of high-brightness LED is more than 50,000 hours; the life of solar battery is 4-7 years. The performance of the battery directly affects the operation and service life of solar road lights.
