Solar powered street lights are street lights powered by solar energy. Solar street lights use solar panels, which use solar energy as an alternative energy source. The solar panels are installed on poles or lighting structures. These panels charge rechargeable batteries, which power the solar powered street lights at night. So, how are solar powered street lights panels installed? What should be considered? Let's take a look together!
Steel is often used to make solar panel frames. However, some of its properties are not that great. To ensure its effectiveness, galvanizing is usually done to improve its corrosion resistance. However, in order to save costs, some solar powered street lights manufacturers use cold galvanizing, which results in a very thin coating that has poor corrosion resistance. It's important to differentiate between galvanizing methods.
If you are in a city with heavy salt spray, it is best to choose stainless steel or aluminum alloys that have been heat-treated for better corrosion resistance and durability. If you are in a city like Yichang with a suitable environment, you can choose your solar panel frame according to your actual needs.
In addition to choosing the right frame material, it is important to ensure that the frame is firmly welded or installed to the foundation, so that the solar panels have enough strength and stability to resist weather conditions such as strong winds or snow, as the solar panel installation location is best without any obstructions.
When installing solar panels, lightning protection devices should also be installed, especially in cities with more thunderstorms. Otherwise, nearby lightning strikes can easily cause overvoltage and overcurrent, which can damage the battery back of the solar panel.
Generally, install the photovoltaic special power supply SPD on the DC distribution cabinet (junction box), ground the solar panel with the same potential and provide direct lightning protection. Commercial solar powered street lights have been doing quite well in this regard.
When installing, it is important to understand the positive and negative poles of the solar panel and make sure that the polarity is not reversed. If the polarity is reversed, the solar panel will not work, it cannot be charged, and the controller's indicator light will not light up. In serious cases, the diode may even be burnt out, so be sure to pay attention.
In addition, the wires should be kept as short as possible to reduce the internal resistance of the circuit. The connection should be firm to prevent an increase in contact resistance, which can result in higher work efficiency. Also, pay attention to the ambient temperature. When installing, the wire temperature parameters should be kept with some margin.
When installing solar panels, it is best not to wear metal jewelry to avoid direct contact between the positive and negative poles of the solar panel and metal objects, which could cause a short circuit, or even a fire or explosion in serious cases.
