Nowadays, solar street lamps are widely used. The advantage of solar street lamps is that there is no need for mains power. Each set of solar street lamps has an independent system, and even if one set is damaged, it will not affect the normal use of others. Compared with the later complex maintenance of traditional city circuit lights, the later maintenance of solar street lights is much simpler. Although it is simple, it requires some skills. The following is an introduction to this aspect:
1. The pole fabrication of solar street lamps shall be well protected against wind and water
The fabrication of solar street lamp poles must be based on the different application locations. The size of the battery panel shall be used for different wind pressure calculations. The lamp poles that can withstand the local wind pressure shall be planned and treated with hot galvanizing and plastic spraying. The planning viewpoint of the battery module support shall be based on the local latitude to plan the best device viewpoint. Waterproof joints shall be used at the connection between the support and the main pole to prevent rain from flowing into the controller and battery along the line, Short circuit burning device is formed.
2. The quality of solar panels directly affects the application of the system
Solar street lamps must use solar cell modules provided by enterprises certified by authoritative institutions.
3. The LED light source of the solar street lamp should have a reliable peripheral circuit
The system voltage of solar street lamps is mostly 12V or 24V. Our common light sources include energy-saving lamps, high and low pressure sodium lamps, electrodeless lamps, ceramic metal halide lamps, and LED lamps; In addition to LED lamps, other light sources require low-voltage DC electronic ballasts with high reliability.
4. Application and Protection of Battery in Solar Street Lamp
The discharge capacity of the special solar photovoltaic battery is closely related to the discharge current and ambient temperature. If the discharge current is added or the temperature drops, the battery utilization rate will be low, and the corresponding capacitance will be reduced. With the increase of ambient temperature, the battery capacity is added, otherwise it is reduced; The life of the battery is also being reduced, and vice versa. When the ambient temperature is below 25 ° C, the battery life is 6-8 years; When the ambient temperature is 30 ° C, the battery life is 4-5 years; When the ambient temperature is 30 ° C, the battery life is 2-3 years; When the ambient temperature is 50 ° C, the battery life is 1-1.5 years. Nowadays, many local people choose to add battery boxes on lamp poles, which is not advisable in terms of the impact of temperature on battery life.
5. Solar street lamp should have an excellent controller
It is not enough for a solar street lamp to have only good battery components and batteries. It needs an intelligent control system to integrate them into a whole. If the controller used has overcharge protection and no over discharge protection, so that the battery is over discharged, it can only be replaced with a new battery.
The above post maintenance skills for solar street lamps will be shared here. In a word, if you use solar street lamps for road lighting, you can’t just install the photovoltaic lighting system in place once and for all. You should also provide necessary maintenance, otherwise you will not be able to achieve the long-term brightness of solar street lamps.
