What aspects should be considered when choosing solar street lights

　　 There are many components of solar street lights. To ensure the lighting quality of solar street lights, it is necessary to ensure the quality and matching degree of each component. Then how can we buy a value-added solar street light? Here is a brief introduction from the staff of Changhui Solar Street Light Manufacturer:

　　1. Light pole: The inside and outside of the hot-dip galvanized and sprayed light pole are galvanized together, and the inside should be silver light, while the cold galvanized spray paint is used for galvanizing only the outside. It will turn yellow and change color. The spray paint is thin and easy to scratch off, but the spray paint is thicker and cannot be scratched off;

　　2. Solar street light controller: The solar street light controller should have basic functions such as overload protection, reverse discharge protection, overcharge/discharge protection, load power-on recovery settings, etc. The LED light source should be considered when choosing a solar street light controller Constant current output, output time control, temperature compensation, wireless loss compensation, charging mode, etc. In addition, the use environment of solar street lights must also be considered. Some areas are relatively humid, and the corrosion of the controller must be considered. If the controller is not waterproof, after a long time, the plug buckle is easy to corrode and rust and cause a short circuit, which affects the normal use of the system. Therefore, it is recommended to use a waterproof controller in humid areas;

　　3. Storage battery: The storage battery stores the electric energy generated by the conversion of solar panels into light energy, and then releases it when lighting is needed at night. Currently widely used are lead-acid maintenance-free batteries, ordinary lead-acid batteries and alkaline nickel-cadmium batteries. A battery with too small capacity cannot meet the needs of night lighting; a battery with too large capacity is always in a state of power deficit, which affects the life of the battery and also causes waste.

　　The ratio of battery capacity (Ah) to load capacity (Ah) is preferably 3-6 times or more. The area with fewer consecutive rainy days is about 3 to 4 times, and the area with more consecutive rainy days is about 5 to 6 times. In addition, the battery connection should also be considered. When connecting in parallel, the impact of the imbalance between the individual cells should be considered. The number of parallel groups should not exceed 4 groups, and corresponding measures should be taken according to the actual situation.
