At present, solar street lights have been widely used in many areas, especially in the construction of new rural areas. The advantage of solar street lights is that they do not need to be connected to the mains, each set of solar street lights can operate independently, even if one of them is damaged, it will not affect the normal use of other street lights. Compared with traditional city circuit lights, the later maintenance of solar street lights is relatively easy and the cost is relatively low. Although the post-maintenance work is simple, it requires a certain skill
1. The poles of solar street lights should be waterproof, windproof, and corrosion-proof.
The configuration of the poles of solar street lights needs to be calculated according to the different application scenarios and the size of the required battery panels to calculate the wind pressure resistance requirements, usually hot-dip galvanized plastic spraying is used for surface treatment.
The viewpoint of the battery module bracket planning is based on the local latitude to plan the best device viewpoint. Use waterproof connectors at the connection between the bracket and the main pole to prevent rain from flowing down the line to the controller and battery, causing short circuits between electrodes and burning devices. .
2. The quality of solar panels determines the service life of street lights
The specifications of solar street lamp panels must meet the actual needs of lighting, because the quality of the solar panels directly determines the solar energy absorption efficiency of the street lamp and the lighting life of the street lamp.
3. The LED light source of solar street light must have a reliable peripheral circuit
The system voltage of solar street lights is mostly 12V or 24V. Our commonly used light sources include energy-saving lamps, high and low pressure sodium lamps, induction lamps, ceramic metal halide lamps, LED lamps; in addition to LED lamps, other light sources require high-reliability low-voltage DC Electronic ballast.
4. Application and protection of batteries in solar street lights
The discharge capacity of the solar photovoltaic battery is closely related to the discharge current and the ambient temperature. When the discharge current increases or the temperature drops, the battery utilization rate will be low, and the corresponding electric capacity will be reduced. As the ambient temperature rises, the battery capacity is increasing, and vice versa, it decreases; the battery life is also decreasing, and vice versa. When the ambient temperature is below 25°C, the battery float life is 6-8 years; when the ambient temperature is 30°C, the battery float life is 4-5 years; when the ambient temperature is 30°C, the battery float life is 2- 3 years; when the ambient temperature is 50°C, the floating charge life of the battery is 1-1.5 years. Nowadays, many local places use the practice of adding battery boxes to light poles. From the perspective of the influence of battery operating temperature on lifespan, it is undesirable.
5. Solar street lights must have an outstanding controller
Solar street lights have good battery components and batteries. It needs an intelligent control system to integrate them into a whole. The controller we used at the beginning has overcharge protection and no overdischarge protection, so that the battery is overdischarged. I had to replace the battery with a new one.
The above post-maintenance techniques for solar street lights are shared with you. Often, solar outdoor lighting projects have to play a sustained and stable role, and the post-maintenance work is far greater than the pre-construction work.
