With the gradual popularization of solar street lamps, there are more and more solar street lamp manufacturers making solar street lamps, and the situation of each manufacturer is also uneven. Therefore, many customers do not know how to choose solar street lamps that are suitable for their needs. However, upon closer inspection, you can really see some tricks. Let's start with the price of solar street lamps. What should we pay attention to

Firstly, it is important to look at the solar panels of solar street lights: The prices of solar panels have been relatively low in the past six months, and there are many options available. It is recommended to buy high-quality ones in large quantities. And we cannot blindly make maps cheap, because many ultra-low priced battery panels in the market are made of inefficient chips and fragments.

Secondly, it depends on what type of street lamp holder is used, and the prices of different grades of quality will vary greatly. Generally, LED lights are used, but those that are poorly purchased have severe light attenuation and become darker after a short period of time. Therefore, do not rely solely on the cheap price of solar street lamp holders at that time, and their performance may not be as good as that of solar street lamp holders at a good price point.

Thirdly, it depends on the solar street lamp battery: the price fluctuates slightly. The quality is related to the maintenance cost in the future, and replacing old batteries for the project is also a significant cost. Therefore, the battery of solar street lights is an issue that cannot be ignored.

Fourthly, it depends on the height of the solar street lamp pole: 5-12 meters or even higher; The inner and outer diameters also determine the wall thickness and flange; Is it hot-dip galvanized and painted; The amount of materials used also determines the price.

Fifth, it depends on the fact that there are currently not many specialized controllers for solar street light controllers. Although the controller occupies a relatively core position in the entire system (if the controller does not pass the standard, efficiency is not limited, it may also burn out the battery panel, affect the battery, and more likely damage the load), the following are some specific information:

The selection of solar street light controllers is generally based on the current, and the current mainly depends on the ratio of battery panel power to battery voltage and the ratio of load power to battery voltage, whichever is higher. For example, if the load is 60W, the battery panel is equipped with 100W, and the battery voltage is 12V, 60W/12V=5A, 100W/12V=8.333A, so choose a 12V10A solar controller~~. Of course, you also need other functions, so you need to clarify your requirements. For example, if you want to keep the load working when the battery runs out of power, you can use a complementary controller with mains power; If you want the lamp to have full power for the first 5 hours and half power for the second half of the night, then you need to choose a controller with half power; You need to switch off the load automatically from dark to 0:00, and then from 4am to dawn. You can choose a dual period controller; Also, your system has two loads. If you want separate controllers, you can choose a dual controller!
