When the 21st century comes, people enter a modern era, a new era of new ideas, and technology plays an important supporting role in the daily life of each of us. We ca n’t do without it. Even the integrated solar street lights are so rich in technological factors. Solar energy is used in many fields and is also used in street lighting. The reason for such respect.
The first and most significant point is to save resources, low carbon and environmental protection. Solar street lights are a one-time investment and maintenance-free product. No external power supply is required, and no extra electricity costs. The reason why it is called maintenance-free is because the quality is sufficient. Well, the life is long enough. In the five or six years after installation and use, in addition to the faulty problems caused by the sloppy quality of the original accessories, you do not need to invest any manpower, and the return is good.
The second major reason is the reliability and stability of all in one solar street light. The failure rate is low, and the street lights of the independent system do not affect each other, and will not be affected by the power failure. The only external factors affecting it are the sun and temperature.
The third lighting effect is good. The bright and efficient lighting method makes the distance between each light pole still large. It can still ensure the lighting effect through the system’s own setting of the light switch time and light control time control control method, without manpower. manual setting.
However, because there is no industry standard or national standard in the solar street light market, many solar street light manufacturers do not have standard equipment. Therefore, when selecting solar street lights, you must configure them according to local actual conditions, but you cannot blindly configure them. The pursuit of configuration, after all, the price of solar street lights has a great relationship with the configuration, the higher the configuration, the more expensive the price, so we must consider various aspects, we must consider the issues to pay attention to when buying solar street lights.
The first solar led street light price problem:
The price of solar street light is a one-time investment. Compared with traditional street lights, the price will be higher, but specifically how much higher it is, it may not be necessary. Because the lighting equipment we use does not determine its price according to its first investment, it must also consider its later use costs.
As far as the product itself is concerned, the price of solar street lights is higher than traditional street lights; if the costs incurred during the construction process and the later costs are taken into account, the price of traditional street lights will be much higher than the price of solar street lights, and the larger the scale The larger the difference, the greater the price.
If the purchase cost, construction cost, later use cost, and maintenance cost are taken into account, it is more cost-effective to use solar street lights than traditional street lights. The initial investment in the installation of solar street lights is basically the same as the price of traditional lamps, but in the process of use, solar street lights do not consume electricity and can save a lot of electricity costs, while traditional street lights require electricity. The post-maintenance cost of solar street lamps is low, while the replacement and maintenance of traditional street lamps are frequent.
It is also necessary to consider the life of the entire lamp. For lighting products, life determines value, and value determines price. The life of solar street lights mainly depends on the life of the lithium battery and the driving circuit of the LED light source, so the price of solar street lights is also affected by the life of the lamps.
The above are the factors that affect the price of solar street lights. In general, the price of solar street lights must be measured according to various aspects. It may be costly in the early stage, but it can save a lot of electricity bills in the later stage, and it has the characteristics of simple maintenance, which is consistent with long-term considerations And the only choice for energy saving and environmental protection.
Second solar street light quality problem
The quality problems of integrated solar street lights are generally closely related to the quality of the accessories of solar street lights
1: The service life of the battery should also be considered in the application of the entire street light system. The general battery is guaranteed for three or five years, but the general battery will be dissatisfied with charging after one year or even half a year. Some actual charging rates are It may drop to about 50%, which will affect the normal night lighting during continuous rainy days, so it is especially important to choose a better battery. Now we normally use lithium batteries, which can be charged and discharged more than 500 times and have a service life of more than 8 years, which has more advantages than ordinary solar street lights.
2: Some engineering companies often choose LED lights as the lighting of solar street lights, but the quality of LED lights is uneven, and LEDs with severe light attenuation may attenuate 50% of the light intensity for half a year. So be sure to choose LED lights with slower decay. Our company now uses high-efficiency lamp beads with a luminous efficiency of more than 200 lumens and a lifetime of more than 5WH.
3: The choice of controller is often an issue that is ignored by everyone. The quality of the controller is uneven. Our company now uses all self-produced controllers to control quality and quality at the source.
4: Farther away from urban areas, we should also pay attention to anti-theft work. Many construction companies have not implemented effective anti-theft because of negligent construction, which led to the theft of accumulators, batteries and other accessories, which not only affected normal lighting but also caused unnecessary property loss. In the previous engineering cases, most of the stolen batteries were batteries. Placing the batteries buried in the ground with cement is an effective anti-theft measure. It is best to weld and strengthen the battery box when it is installed on the lamp pole. Now we are using lithium batteries, which are hung on the top of the light pole, which is more effective in preventing theft.
5: The controller is waterproof. The controller is generally installed in the lampshade and battery box, and generally does not enter water. However, in actual engineering cases, the connection lines of the controller terminals are often short-circuited because rainwater flows into the controller along the connection lines. Therefore, you should pay attention to bend the internal connection line into a “U” shape and fix it during construction. The external connection line can also be fixed as a “U” shape, so that rainwater cannot penetrate and cause a short circuit in the controller. Apply waterproof glue to the interface.
6: In the practical application of many solar street lights, solar street lights in many places can not meet the needs of normal lighting, especially in rainy and rainy days. In addition to using poor quality related components, another major reason is to reduce component costs blindly. , Do not design and configure according to demand, reduce the use of battery panels and storage standards, so the street lights in rainy days can not provide lighting. The company’s solar street lights have been tested and can be used for 20 consecutive days in rainy and rainy days.
Third: After-sales and maintenance of solar street lights
Recently, many customers have called us to ask whether the solar street lights we installed used gel batteries or lead-acid batteries. Now some solar street lights are off, and some solar street lights are turned on for a short time. How to repair these solar street lights? Can lead-acid batteries be replaced by lithium batteries? The five major components of solar street lights are: solar photovoltaic modules, lamp head light sources, controllers, batteries, and light poles. Light poles and photovoltaic modules have a service life of more than 20 years and will not be easily damaged. And the reason that the solar street light does not turn on is most often the failure cause of the light source, controller, and battery. Now I will explain the specific reasons for the failure of the solar street light and the reason why the solar street light does not light (professional maintenance solutions).
Causes of Solar Street Lights
First, solar street light battery failure damage (accounting for 80% of the cause of failure)
Solar street light battery: lead-acid battery (life is about 2 years), gel battery (life is about 3 years), lithium battery (life is 5 years 6 years).
Because the early solar street lights used lead-acid batteries (cheap prices), even after being used for 1 to 2 years, even if it is not damaged, the service life will be affected, which will affect the charging and discharging performance, resulting in shorter lighting time of solar street lights. , Solar street lights do not light up and other failure phenomena.
The controller of the solar street light controls the parameters such as the charging and discharging time of the solar street light and the voltage and power. If the quality is not hard enough, if it encounters natural environment rain or lightning strikes or other reasons, the controller will not work properly, which will cause the controller Damage. Of course, damage to the battery will also cause damage to the controller.
Third, solar street light lamp head light source failure damage (accounting for 10% of the cause of the failure)
The lamp head light source of the solar street light is generally not damaged. If it is considered to be damaged, let alone another thing, it is that the battery may be damaged at the same time, which may cause instant damage to the light source.
Reasons for Solar Street Lights Not Lighting (Professional Maintenance Solutions) Fourth, Solar Street Light Failure Solutions
(1) Maintenance and replacement of solar street light batteries: (recommended to find professional technicians to operate)
1: Remove the controller.
2: Dig a pit and take out the battery.
3: Put on the new battery cable, and connect the cable according to the original wiring method.
4: If the lead-acid battery is replaced with a lithium battery, professional technical engineers need to match the battery voltage and capacity, and then replace the dedicated controller and charger for the lithium battery, and debug them properly before they can be used normally.
Maintenance and replacement method of solar street light controller: (recommended to find professional technicians to operate)
1: Remove the controller.
2: Replace the controller with the matching model and debug normally.
Maintenance and replacement of solar street light source: (recommended to find professional technicians to operate)
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 end interface of the controller is in reliable contact.
2. The charging indicator LEDI (green light) flashes rapidly. The system voltage is too high. Check whether the battery is open or 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 load end wiring is reliable.
4. The load indicator LED3 (red light) flashes quickly and the load is not working. The load is short-circuited.
5. The load indicator LED3 (red light) flashes slowly and the load is not working. 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 light is used for outdoor lighting. It often encounters high temperature and rain, low temperature rain and snow. Solar street light controllers are usually installed in the light pole, which easily causes water to enter the controller and cause a short circuit. First observe whether there is water rust on the terminal of the controller. If there is a high possibility that the controller is damaged, the battery voltage is not measured. For example, in a 12V solar street light power supply system, the battery voltage is lower than 10.8V, and the battery is no longer charged. And need to be replaced. Then check whether there is voltage and current output under the normal working conditions of the SkyTeam battery board. If the battery board is not damaged, replace the battery board. None of the above, you should check the light source, only connect to the light source to see if it is lit, if not, replace the light source.
8. The lamp head flashes. The cause of this failure is poor line contact, the battery loses power, and the stored power is severely reduced. Replace the battery if the line is not defective.
9. The lighting time is short and the duration of rainy days is short. Usually, the storage capacity of the storage battery is reduced, which is caused by sufficient storage. Replace with a reasonable battery.
10. Solar street light source is not all on. Many solar street lights use dot-matrix LED light sources. In addition to the quality of the LED light source itself, some lamp beads can cause this situation. The solution is to replace the corresponding lamp beads, weld firmly or replace the entire street lamp head
