3. Working principle of solar streetlights

Explanation of the working principle of solar street lights: During the day, solar street lights are controlled by intelligent controllers. The solar panels absorb solar light and convert it into electrical energy, During the day, the solar cell components charge the battery pack. At night, the battery provides power to the LED light source to realize the lighting function.

The DC controller can ensure that the battery pack is not damaged due to overcharging or over-discharging. At the same time, it has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.

7. Installation steps of solar streetlights

solar street light installation

(I) Foundation pouring

1. Determine the location of the standing lamp; survey the geological conditions. If the ground surface is soft soil within 1m2, the excavation depth should be deepened; at the same time, confirm that there are no other facilities (such as cables, pipes, etc.) below the excavation location, and there are no long-term sunshade objects on the top of the street lamp, otherwise the location should be changed appropriately;

2. Reserve (excavate) a 1m3 pit that meets the standard at the location of the standing lamp; position and pour the embedded parts, place the embedded parts in the middle of the square pit, place one end of the PVC threading pipe in the middle of the embedded parts, and the other end in the battery storage area.

Pay attention to keeping the pre-embedded parts The embedded parts, foundation, and original ground are on the same level (or the top of the screw rod is on the same level as the original ground, depending on the site requirements), and one side must be parallel to the road so that the lamp pole can be straight and not tilted after erection, and then cast and fixed with C20 concrete. During the casting process, the vibrator should be used continuously to ensure overall density and firmness;

3. After the construction is completed, the residual mud on the positioning plate should be cleaned in time, and the impurities on the bolts should be cleaned with waste oil;

4. During the solidification of concrete, watering and maintenance should be carried out regularly; the chandelier can be installed only after the concrete is completely solidified (generally more than 72 hours).

(II) Solar Panel Installation

1. Before connecting the positive and negative poles of the solar panel to the controller, measures must be taken to avoid short circuits;

2. The solar cell module must be firmly and reliably connected to the bracket;

3. The output wire of the module should not be exposed and should be tied with a cable tie;

4. The direction of the battery module should face due south, according to the compass direction.

(III) Battery Installation

1. When placing the battery in the control box, it must be handled with care to prevent the control box from being damaged;

2. The connecting wires between the batteries must be pressed on the battery terminals with bolts and copper gaskets must be used to enhance conductivity;

3. After the output wire is connected to the battery, a short circuit is prohibited under any circumstances to avoid damaging the battery;

4. The output wire of the battery must be connected to the controller in the pole through a PVC threading tube;

5. After the above is completed, check the wiring at the controller end to prevent a short circuit. Close the door of the control box after normal operation.

(IV) Lighting installation

1. Fix the components of each part: fix the solar panel on the solar panel bracket, fix the lamp head on the cantilever arm, then fix the bracket and cantilever arm to the main pole, and lead the connecting wire to the control box (battery box);

2. Before lifting the light pole, first check whether the fasteners of each part are firm, whether the lamp head is installed correctly, whether the light source works normally, and then check whether the simple debugging system works normally, loosen the solar panel connection wire on the controller, and the light source works;

3. When lifting the main light pole, pay attention to safety precautions, and tighten the screws. If the angle of the component facing the sun deviates, you need to go up Adjust the sun-facing end to face due south;

4. Put the battery into the battery box and connect the connection wire to the controller according to the technical requirements; first connect the battery, then the load, and then the solar panel; when wiring, be sure to pay attention to the wiring terminals marked on the controller. The positive and negative polarities cannot collide and cannot be connected in reverse; otherwise, the controller will be damaged;

5. Debug whether the system works normally; loosen the solar panel connection wire on the controller, when the light is on, connect the solar panel connection wire, when the light is off, and carefully observe the changes in the indicator lights on the controller. If everything is normal, the control box can be sealed.

8. How to choose solar street lights:

40w,60w,100w,120w solar street light

1. LED light source: Solar streetlights generally use LED light sources, and most of them use 1W high-power lamp beads. Generally, the power of one lamp bead is 1W, and the number of lamp beads is the number of watts;

2. Solar panels: Solar street light panels generally use single crystal and polycrystalline. The price of a single crystal is higher than that of polycrystalline. Generally, customers do not have professional measuring instruments when purchasing. It is recommended to use a size area to measure and weigh. The larger the size area, the larger the size of the panel is proportional to the power of the panel;

3. Battery: Solar street light batteries are generally divided into three types: lead-acid batteries, gel batteries, and lithium batteries. Currently, gel and lithium batteries are commonly used. The cost of lithium batteries is higher than that of gel, and that of gel is higher than that of lead-acid batteries;

4. Light pole: The height, shape, and parameters of the light pole are mainly considered. The higher the height of the light pole, the higher the corresponding parameters should be, and the price will also increase. The more complex the shape of the light pole, the higher the price will also increase.
