Which is better, solar street lights or mains street lights? Which one is more cost-effective? Based on this question, many buyers are puzzled and don't know how to choose. Let's carefully analyze the advantages and disadvantages between the two to see which lamp is more suitable for our needs.

1. Working principle:
① The working principle of solar street lights is that solar panels collect sunlight, and the effective lighting time is from 10 am to 4 pm (taking summer in northern China as an example), converting light energy into electrical energy, and storing the electrical energy in the battery through the controller. When the sun sets and the light becomes dim, the controller will automatically activate the street light and start lighting.
② The working principle of mains street lights is to connect all the main lines of street lights in series from the ground or underground in advance, and then connect them to the street light lines, and then use the time controller to uniformly set the lighting time of the street lights, what time to turn on the lights, and what time to turn off the lights.

2. Scope of application: Solar street lights are very suitable for remote areas with scarce power resources. Since some areas are affected by factors such as the environment and construction difficulties, solar street lights are the most suitable choice in this case; there are also some rural areas and highway central isolation areas. In this case, if the main line is overhead, it is easy to cause damage to the lamps or excessive aging of the wires to cause circuit breakage due to factors such as sun exposure, thunderstorms and electric shocks. If it goes underground, it will also require high pipe jacking costs and labor costs. At this time, solar street lights become the best choice.

Similarly, in areas with sufficient power resources and convenient ground line connections, city street lights are a good choice.

3. Service life: In fact, the two are similar. City street lights generally provide a 3-5 year warranty and regularly check and replace the lamp heads. In the solar street light industry, due to the continuous development and upgrading of batteries, it is now completely possible to achieve a 5-year warranty. In fact, the batteries used by Solway are top domestic brands with a cycle count of up to 5,000 times and a lifespan of up to 8-10 years. Combined with the operation of the entire solar lighting system, Solway has enough confidence to provide customers with a 5-year warranty for the entire lamp.

4. Configuration of lamps: Whether it is a mains circuit lamp or a solar street lamp, LED light sources have also made great breakthroughs, reaching up to 210LM/W to help reduce wattage and save electricity bills, energy saving, environmental protection, and extend life. Although solar street lights do not require electricity, the initial investment will be slightly higher.

5. Disadvantages of each:

① Disadvantages of solar street lights

Considering the problem of battery life on rainy days, it is necessary to configure enough solar panels and batteries, and the cost will increase accordingly. This is the main reason why the initial investment of solar street lights is higher

② Disadvantages of mains circuit lamps:

The current of LED light sources cannot be adjusted, resulting in full power during the entire lighting period. In the second half of the night when too much lighting brightness is not needed, it is still full power, wasting energy.

Secondly, maintenance: As long as there is a problem with the main cable of the lamp, it is difficult to deal with it (underground and overhead are very troublesome). If a short circuit occurs, it must be checked one by one. If it is light, it can be connected and repaired, and if it is heavy, the entire cable needs to be replaced.
