Solar street light configuration calculation

With the increasing shortage of traditional energy sources, the application of solar energy will become more and more extensive, especially in the field of solar power generation, which has developed into a mature sunrise industry in just a few years.

1: One of the most important factors restricting the application of solar power generation is the price. Take a two-way Solar Street Light as an example. The two-way load is 60 watts in total. (Efficient illumination of the middle and lower reaches of the Yangtze River is 4.5h/day, nightly. 7 hours of discharge, increase the 20% reserve of the battery board) The battery board needs about 160W, calculated according to 20 yuan per watt, the cost of the battery board is 3200 yuan, plus the battery pack cost of 180AH is also 1800 Left and right, the one-time input cost of the entire street lamp is much higher than the city circuit lamp, which has caused the main bottleneck in the field of solar street lamp application.

2: The service life of the battery should also be considered in the application of the entire street lamp system. The general battery warranty is three or five years, but the general battery will be charged dissatisfied after one year or even six months. Some actual charging rates are It may fall to around 50%, which will definitely affect the normal nighttime illumination during continuous rainy days, so it is especially important to choose a better battery.

3: Some engineering companies often use LED lights as the lighting for solar street lights, but the quality of LED lights is uneven, and LEDs with severe light decay may attenuate 50% of the illuminance in half a year. Therefore, we must choose LED lights with slower light decay, or use induction lamps, low-pressure sodium lamps, etc.

4: The choice of controller is often a problem that is ignored by the engineering company. The quality of the controller is uneven. The market price of the controller of 12V/10A ranges from 100-200 yuan, although it is the lowest value of the entire street lamp system. Part, but it is a very important part. The quality of the controller directly affects the component life of the solar street lighting system and the procurement cost of the whole system. One: the controller with lower power consumption should be selected, and the controller will work 24 hours a day, if its own power consumption is large, To consume some of the power, it is best to choose a controller that consumes less than 1 milliamp (MA). Second, to choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the panel, especially in the winter or under-light period, the MCT charging mode is about 20% higher than other. Third: The controller with two adjustable power should be selected. The controller with power adjustment has been widely promoted. It can automatically turn off one or two illuminations during the night when pedestrians are scarce, save electricity, and can also adjust the power for LED lights. . In addition to selecting the above power-saving functions, you should also pay attention to the controller's protection function for components such as batteries. For example, the controller with trickle charge mode can protect the battery well, increase the battery life, and set the controller undervoltage protection. For the value, try to adjust the undervoltage protection value to ≥ 11.1V to prevent the battery from being over-discharged.

5: From the farther away from the urban area, you should pay attention to anti-theft work. Many engineering companies have not carried out effective anti-theft because of negligence in construction, resulting in the theft of components such as batteries and battery panels, which not only affects normal lighting, but also causes unnecessary property loss. At present, most of the stolen houses in the engineering case are batteries, and the battery is buried in the underground with cement pouring. It is an effective anti-theft measure in the light pole.

It is best to weld the battery box to the welding reinforcement.

6: The controller is waterproof. The controller is usually installed in the lamp cover and battery box. Generally, the water will not enter the water. However, in the actual engineering case, the connecting line of the controller terminal often causes a short circuit because the rainwater flows into the controller along the connecting line. Therefore, during construction, it should be noted that the internal connecting wire is bent into a "U" shape and solidified, and the external connecting wire can also be fixed to the "U" type, so that the rainwater cannot be dripped into the controller to short-circuit, and the inner and outer wires can also be used. Apply waterproof glue to the interface.

7: In the practical application of many solar street lamps, solar street lamps in many places cannot meet the normal lighting needs, especially in rainy days. In addition to the use of poor quality related components, another major reason is to reduce component costs. The design is not designed according to the requirements, and the use standard of the battery board and the battery is reduced, so that the street lamp cannot provide illumination in the rainy day.
