The 15W solar street light receives the light mainly through the battery panel, to realize the photoelectric conversion at the back, and successfully lights up the light source. If the 15W solar street light battery panel is not installed properly, it is likely to fail to achieve the desired lighting effect.
This installation not only refers to whether the components are loose, or whether there are any obstructions on the top but also its installation angle, some safety devices on the top, etc. it should not be careless. Then, what problems should be paid attention to when installing solar street light?
1、 Choose a border material
Solar energy frames are often made of steel. Some properties of this kind of materials are not very good. To ensure the use effect, hot galvanizing treatment is usually carried out to improve its corrosion resistance. However, to save costs, some solar street light manufacturers will use cold galvanizing treatment. The coating treated in this way is very thin, and the corrosion resistance is not good, so we should pay attention to distinguish Farewell.
If it's in some cities such as coastal areas, where the salt spray is heavy, it's better to choose stainless steel or aluminum alloy for overheating treatment, which has higher corrosion resistance and durability. If it's in a city like Yichang, the environment is relatively suitable, and the selection of the battery board frame can be based on your actual needs.
Besides, in addition to choosing a good frame material, it is necessary to ensure that the frame and the foundation are welded or installed firmly and that the solar panel can have sufficient strength and stability to withstand the weather such as strong wind or snow. After all, the place where the solar panel is installed is the best place without barriers.
2、 Find out the positive and negative poles of components
Secondly, pay attention to make sure the positive and negative poles of the battery board during installation, and pay attention to that the polarity cannot be connected wrongly. If it is connected wrongly, the battery board will not work, the charging point will not be filled, the indicator light of the controller will not be on, and even the diode will be burned seriously, so it must be noted.
Besides, the conductor should be as short as possible, reduce the internal resistance of the line, connect firmly, and do not increase the contact resistance, so that the working efficiency will be higher. Besides, the ambient temperature should also be noted. According to this temperature during installation, the temperature parameters of the conductor should have a margin.
3、 Installation of lightning protection device
When installing the battery board, also pay attention to the installation of lightning protection devices, especially suitable for cities with more thunderstorms, or lightning strikes nearby, which is easy to produce over-voltage and over-current, and the battery back is damaged by the lightning surge.
In general, the special photovoltaic power supply SPD is installed in the DC distribution cabinet (combiner box), and the battery board is well-grounded and protected against direct lightning. The solar street light from Nantai has always been skilled in this respect.
4、 Do not wear metal jewelry
When installing the battery board, it is better not to wear metal ornaments, to avoid the positive and negative poles of the battery board directly contacting the metal objects, or there may be short circuit, or fire, explosion, and other situations may occur in serious cases.
