JDSOLAR battery assembly bracket
1) Inclination design
In order to make the solar cell module receive as much solar radiation energy as possible in one year, we have to choose an optimal tilt angle for the solar cell module.
The discussion about the optimal tilt angle of the solar cell module is used in different regions according to different regions.
2) Wind resistance design
In the solar street light system, a structural problem that needs to be paid more attention to is the wind resistance design. The wind resistance design is mainly divided into two major parts, one is the wind resistance design of the battery component bracket, and the other is the wind resistance design of the lamp post. The following analysis is made separately according to the above two.
Wind resistance design of solar cell module bracket
According to the technical parameter data of battery module manufacturers, the solar cell module can withstand upwind pressure of 2700Pa. If the wind resistance coefficient is selected to be 27m / s (equivalent to a ten-level typhoon), according to non-viscous fluid mechanics, the wind pressure of the battery assembly is only 365Pa. Therefore, the component itself can withstand 27m / s wind speed without damage. Therefore, the key consideration in the design is the connection between the battery assembly bracket and the lamp post.
In the design of the street lamp system, the connection design of the battery assembly bracket and the lamp post is fixedly connected by a bolt rod.
Windproof design of street lamppost
The parameters of JDSOLAR street lamp are as follows:
Panel tilt angle A = 16o pole height = 5m
The design selects the width of the welding seam at the bottom of the lamp post δ = 4mm.
The surface of the weld is the destruction surface of the lamp post. The distance from the calculation point P of the resistance moment W of the destruction surface of the lamp pole to the action line of the panel load F on the lamp pole is
PQ = [5000 (168 6) / tan16o] × Sin16o = 1545mm = 1.545m. Therefore, the moment of wind load on the destruction surface of the lamp pole M = F × 1.545.
According to the design maximum allowable wind speed of 27m / s, the basic load of the 2 × 30W dual-lamp solar street light panel is 730N. Considering the safety factor of 1.3, F = 1.3 × 730 = 949N.
Therefore, M = F × 1.545 = 949 × 1.545 = 1466N.m.
According to the mathematical derivation, the resistance moment W = π × (3r2δ 3rδ2 δ3) of the circular ring-shaped failure surface.
In the above formula, r is the inner diameter of the ring and δ is the width of the ring.
Resistance moment of failure surface W = π × (3r2δ 3rδ2 δ3)
= π × (3 × 842 × 4 3 × 84 × 42 43) = 88768mm3
= 88.768 × 10-6 m3
Stress caused by wind load acting on the failure surface = M / W
= 1466 / (88.768 × 10-6) = 16.5 × 106pa = 16.5 Mpa << 215Mpa
Among them, 215 Mpa is the bending strength of Q235 steel.
Therefore, the width of the weld selected by the design meets the requirements. As long as the welding quality can be guaranteed, the wind resistance of the lamp post is no problem.
JDSOLAR controller
The main function of the solar charge and discharge controller is to protect the battery. Basic functions must have overcharge protection, overdischarge protection, light control, time control, anti-reverse connection, charging trickle protection, undervoltage protection, waterproof protection, etc.
1) Device selection
In the selection of devices, there are currently single-chip microcomputers and comparators. There are many schemes, each with its own characteristics and advantages. The corresponding scheme should be selected according to the needs of the customer group, which will not be elaborated here.
2) Surface treatment
This series of products adopts the new technology of electrostatic coating, mainly based on FP professional building material coatings, which can meet the requirements of customers on the color and environment of the product. Climate environment. The processing technology is designed to be coated on the basis of hot-dip zinc, which greatly improves the performance of the product and reaches the most stringent AAMA2605.2005 requirements. Other indicators have reached or exceeded the relevant requirements of GB.
3) Charging trickle protectionWhen the JDSOLAR solar panel charges the battery, after the battery reaches the peak voltage, if the high-voltage charging continues, it will easily cause the battery to lose water or runaway; if the battery stops charging, the battery will not be saturated. This controller immediately reduces the voltage by 1V after charging to the peak voltage, and then enters the trickle charging state, which ensures that the battery can be stabilized in a full state, and at the same time avoids water loss or runaway. It protects the battery, also improves the number of times the battery is charged, and has a longer service life.

JDSOLAR solar street light configuration calculation
Calculate current
Such as: 12V battery system; 2 30W lamps, a total of 60 watts.
Current = 60W ÷ 12V = 5 A
Capacity calculationSuch as: street lamp lighting time of 9.5 hours per night, the actual full load lighting is 7 hours (h);
Example 1: 1 LED light
(For example, when 100% power is turned on at 7:30 in the evening, it will be reduced to 50% power at 11:00 in the evening, and then 100% power after 4:00 in the morning, and turned off at 5:00 in the morning)
Example 2: 2-way non-LED lamp (low-pressure sodium lamp, electrodeless lamp, energy-saving lamp, etc.)
(For example, if the two circuits are open at 7:30 in the evening, the first channel will be closed at 11:00 in the evening, the second channel will be opened at 4:00 in the morning, and closed at 5:00 in the morning)
Need to meet the lighting needs of 5 consecutive rainy days. (5 days plus the lighting of the night before the rainy day, total 6 days)
Battery = 5A × 7h × (5 + 1) days
= 5A × 42h = 210 AH
In addition, in order to prevent the battery from overcharging and overdischarging, the battery is generally charged to about 90%; the discharge remains about 5% -20%. So 210AH is only about 70% -85% of the real standard in the application. In addition, the actual loss must be measured according to the load. The actual operating current is affected by the constant current source, ballast, and line loss. It may increase by about 15% -25% on the basis of 5A.
Peak calculation of JDSOLAR solar street lamp
The cumulative lighting time of street lamps per night needs to be 7 hours (h);
★: The average daily exposure time of the solar panel is 4.5 hours (h);
The minimum reserve of 20% of the demand for solar panels should be relaxed at least.
WP ÷ 17.4V = (5A × 7h × 120%) ÷ 4.5h
WP ÷ 17.4V = 9.33
WP = 162 (W)
★: The daily sunshine time of 4.5h is the sunshine coefficient of the middle and lower reaches of the Yangtze River.
In addition, in solar street light components, the line loss, the loss of the controller, and the power consumption of the ballast or constant current source are different. In practical applications, it may be about 15% -25%. Therefore, 162W is only a theoretical value, which needs to be increased according to the actual situation.
JDSOLAR solar street light installation steps
Foundation pouring
Determine the position of the standing lamp; survey the geological situation, if the ground surface is all soft and soft, then the excavation depth should be deepened; at the same time, make sure that there are no other facilities (such as cables, pipes, etc.) below the excavation position, and the top of the street lamp is not long Shade objects, otherwise it is necessary to change the position appropriately.
Reserve (excavate) 1 m 3 pits in accordance with the standard in the position of the standing lamps; perform positioning and pouring of embedded parts. The embedded parts are placed in the middle of the square pit, one end of the PVC threading pipe is placed in the middle of the embedded parts, and the other end is placed in the storage place of the battery (as shown in the above figure). Pay attention to keep the embedded parts, the foundation and the original ground on the same horizontal plane (or the top of the screw and the original ground on the same horizontal plane, depending on the site needs), one side should be parallel to the road; this can ensure that the lamp pole is erected and the rear end is right Not skewed. Then use C20 concrete to cast and fix it. During the pouring process, the vibrating rod should not be used to vibrate to ensure the overall compactness and firmness.
After the construction is completed, clean up the residual sludge on the positioning plate in time, and clean the impurities on the bolts with waste oil.
In the process of solidification of concrete, it should be regularly watered and cured; only when the concrete is completely solidified (generally more than 72 hours) can the pendant lamp be installed.

After completing the above, check the wiring of the controller to prevent short circuit. Close the door of the control box when it is normal.
JDSOLAR solar street light fixture installation
Fix the components of each part: the solar panel is fixed on the solar panel bracket, the lamp head is fixed to the pick arm, and then the bracket and the pick arm are fixed to the main pole, and the connection cable is led to the control box (battery box).
Before lifting the lamp pole, first check whether the fasteners in each part are firm, whether the lamp head is installed correctly, and whether the light source is working properly. Then check whether the system works normally in the simple commissioning; loosen the solar panel cable on the controller and the light source works.
When lifting the main light pole, pay attention to safety precautions; the screws are absolutely fastened, if the angle of the component's sun is different, you need to adjust the direction of the sun toward the south.
Put the battery into the battery box, and connect the cable to the controller according to the technical requirements; connect the battery first, then the load, and then connect the solar panel; when wiring, be sure to pay attention to the wiring and the terminal marked on the controller. If the connection is wrong, the positive and negative polarities cannot collide and cannot be reversed; otherwise the controller will be damaged.
Whether the debugging system is working properly; loosen the solar panel connection cable on the controller, the light is on; connect the solar panel connection cable, the light is off; at the same time carefully observe the changes of the indicator lights on the controller; box.
Precautions for installation of JDSOLAR solar street light
If the user installs the lamp on the ground by himself, the precautions are as follows:
Solar street lights use solar radiation as energy. Whether the sunlight shining on the photovoltaic cell components is sufficient will directly affect the lighting effect of the lamps. Therefore, when choosing the installation location of the lamps, the solar battery modules can radiate sunlight at any time period without leaves And other obstructions.
When threading, be sure not to pinch the wire at the connection of the lamp post. The connection point of the wire should be firmly connected and wrapped with PVC tape.
When using, in order to ensure beautiful appearance and the battery module can better receive the solar radiation, please clean the dust on the battery module once every six months, but do not rinse with water from bottom to top.
Use defects of JDSOLAR solar street lamp
With the use of solar street light technology, solar street lights appeared in the market. However, in the actual research and application of LED street lights, the inherent defects of solar LED street lights cannot be avoided and are difficult to overcome:
The first to bear the brunt of this system, which has "energy-saving and environmental protection" as its main selling point, is that it has a large waste of resource allocation. Because street light products have mandatory standard requirements, which include the "power shortage rate" indicator, it does not allow landscape lighting products to work without rainy days. In this way, from the technical design point of view, the collection and storage of energy must be based on the most unfavourable climatic conditions (seasons with short sunshine hours, continuous rainy days, etc.). In this way, under most usage conditions, Most of the energy configuration (solar cells) and power storage devices are idle. Not only is the system cost necessarily high, but it is also contrary to the theme of energy saving and comprehensive utilization of the system itself.
In addition, some seemingly technically simple problems also need to be solved with relatively high cost in practical applications, including: First, the problem of centralized management, if you do not use electrical wiring, it is very It is difficult to achieve centralized management and remote monitoring, which are more important for street lamps. However, if electrical circuits are reconfigured, it will not only increase costs, but also weaken the meaning of products in "selling points"; second, the life of solar cells, battery life and other The lifespan of the control components is often lower than the lifespan of the LED, which brings about many problems that need to be solved to achieve the long life of the entire system, and it also generates relatively high maintenance costs; third, because the system uses DC batteries , It is very easy to be stolen, so anti-theft is also a big problem of the system. In addition, the weight problem of solar cells with a relatively high installation height leads to an increase in the windproof capacity of the lamp pole design and an increase in cost. These problems are all problems that cannot be fundamentally solved by solar LED lighting systems. .
Corresponding to this, as the cost of LED products continues to decrease, the cost performance of LED street lamps using city power is continuously improving. Combining its core advantages in life and power saving, after stripping off high-cost solar systems , The one-time investment cost can be reduced to a level acceptable to market applications. In line with its advantages in the concept of "energy-saving" products and the promotion of relevant government departments, the pace of application has begun to move from "demonstration and promotion" to "market promotion" in the true sense. The prospects for applications are becoming clearer.
In the foreseeable future, independent LED street lighting has gradually entered into a better situation, but the combination of application with solar energy is no longer a hot spot.
Of course, to say that this technology is no longer a hot spot is not to say that it is meaningless or has no prospects for development. On the one hand, the application advantages of solar LED lighting in some specific occasions (islands, scenic hilltops, remote locations, etc.) are still obvious, including demonstration applications also have a positive significance, so technical research is still very meaningful; on the other hand, in landscape lighting (yard Lights, lawn lights, etc.), as well as the application of centralized mining and power supply in the solar system regional network that may be promoted in the future, its technology and market have great development prospects.
JDSOLAR solar street lamp common failure treatment method
1. There is voltage on the solar panel, but it cannot be charged, and the LEDI green light is off. Check whether the solar panel interface of the controller is in reliable contact
2. The charging indicator LEDI (green light) flashes rapidly. The system voltage is overpressure. Check whether the battery is open or whether the battery is connected reliably. Or the charging circuit is damaged
3. The load indicator LED3 (red light) is on, but the load is not working Check whether the wiring at the load end is reliable
4. The load indicator LED3 (red light) flashes quickly, and the load does not work, the load is shorted
5. The load indicator LED3 (red light) flashes slowly, and the load does not work The load power is too large
6. LED2 shows red, and the load is not working. Battery voltage protection, please charge
7. The whole light is off. Solar street lights are used for outdoor lighting, and often encounter high temperature and rain, low temperature rain and snow weather, and the solar street light controller is usually installed in the lamp post, which is easy to cause the water to the controller short circuit phenomenon. First observe whether there is water rust on the terminals of the controller. If there is a high possibility that the controller is damaged, no battery voltage measurement is performed. For example, the 12V solar street lamp power supply system. If the battery voltage is less than 10.8V, the battery has no storage. , Need to be replaced. Then check whether there is voltage and current output under normal working conditions of the folding solar panel. If the battery board is not damaged, replace the battery board. The above is no problem, you should check the light source, only connect the power supply to the light source to see if it is lit, and replace the light source if it is not bright.
8. The lamp head flashes. The cause of this failure is poor line contact, battery power loss, and the amount of stored electricity has dropped significantly. Replace the battery if there is no problem with the line.
9. The lighting time is short, and the duration of rainy days is short. Usually, the storage capacity of the storage battery is reduced and the storage capacity is sufficient. Just replace the reasonable battery.
10. The solar street light source is not all bright. Many solar street lamps use dot-matrix LED light sources. In addition to the quality problems of the LED light source, some virtual welding of lamp beads will cause this situation. The solution is to replace the corresponding lamp beads, weld firmly or replace the entire street lamp head.

JDSOLAR Solar Street Light Product Highlights
In terms of working principle, solar street lights use solar energy as the light source, and the solar panel will charge the battery during the day. At night, when lighting is needed, the battery will start to supply power to the light source. It does not need to lay complex and expensive power supply lines in use, so that it can be installed in any environment in any venue, its battery uses natural light, can be recycled, no external power supply, the source is green and environmental protection, when the sunlight is insufficient to a certain extent, solar street lights The switch can be adjusted automatically, which truly achieves unattended and all-weather work.
Compared with the traditional high-voltage power supply incandescent street lamp, JDSOLAR solar street lamp is very different in product characteristics, material structure and power supply line. Solar street lights are a kind of traffic and road condition lighting that our country uses solar energy as a new energy source for street lights. In urban life, street lights play a very important role and are the eyes of our travel and nightlife.
In terms of product features, JDSOLAR solar street lights use solar energy on the light source. During the day, it can use the solar circuit board to charge the battery in the street lamp. At night, the battery can supply power to the lamp, which can fully meet the needs of lighting. The solar power source used by the solar street lamp is green and environmentally friendly, and it can be seen everywhere in the nature. This saves the materials required for laying the power supply line, saves a lot of manpower and material resources, and improves the construction efficiency. In addition, solar street lamps are environmentally friendly, energy-saving and consumption-reducing, have a long service life, and have a stable product structure. They have very good social and economic benefits.
