What are the 'unspoken rules' of the solar street light industry

Every industry has its own 'hidden rules'. The solar street light industry is certainly no exception; having been in this industry for so long, all kinds of people have seen it. In order to provide customers with a fair and reasonable reason, I will disclose a few points for you below: First of all, solar street light uses high-power LEDs, so for it, heat dissipation is the most important. If the LED heat dissipation is not handled well, it will seriously affect its light decay. So how to look at the heat dissipation of the LED? First, the lamp beads are welded on the aluminum substrate, and thermal grease is used in the middle; second, the attachment surface of the aluminum substrate is the aluminum plate, that is, the secondary heat dissipation; third, the yellow aluminum is used The profiles are dissipated three times. You can take samples of Baoding Spectrum for verification. The second is the controller. In order to earn more profits, some suppliers use the non-waterproof controller as a waterproof controller, taking the fake as the real one and shoddy. Then there is the quality of solar panels, which are generally guaranteed by major manufacturers such as Yingli in China. They are all polysilicon, and some are monocrystalline silicon. Remember: domestic monocrystalline silicon technology is not familiar with it, even if you buy monocrystalline silicon. It is definitely not pure monocrystalline silicon! The only way to solve these problems is to visit the door in person, find the right manufacturer, find a good manufacturer, guarantee the quality and quantity, so that the scope of the quality guarantee is easy to talk about; don't buy it in some small workshops , otherwise the consequences will be your own. Generally, solar street lamps are installed in villages, and the government of the town pays for them. The street lamps are installed for the villagers based on the concept of serving the people. However, there are inevitably corrupt and bribery people. The ones who benefit the most are some officials. , do good deeds with rebates.
