Properly purchase integrated solar lamps to avoid the risk of bad solar lamps manufacturers.
Integrated solar lamps are the carrier of solar energy utilization and an effective means to improve our current energy use. With the progress of the times and the enhancement of people's awareness of environmental protection, the market for solar lamps has been expanding and the number of solar lamp manufacturers has been increasing. Therefore, the solar lamp market is now mixed and the price of solar lamps is also true.
Integrated solar lights, solar lamps
So how should our ordinary users simply and conveniently choose practical and cost-effective integrated solar lighting products? Pursuing practicality has always been the foothold of consumer consumption. On this basis, choosing products with relatively low prices for solar lamps is even more popular among consumers, but relatively low prices mean that they have to withstand relatively poor product quality. So we must find a balance before the two, which requires us to have a certain understanding of integrated solar lights. Below we will talk about how to avoid such risks from the following points.
First, the composition of solar lamps.
1. Solar panels are divided into two types: monocrystalline silicon and polycrystalline silicon. The conversion efficiency of monocrystalline silicon is high, and the conversion efficiency of polycrystalline silicon is lower than that of monocrystalline silicon. But when it comes to power, 100W monocrystalline silicon and 100W polycrystalline silicon are a concept, but the volume of polycrystalline silicon will be larger.
2. The battery energy storage part is divided into two types: traditional lead-acid colloid maintenance-free battery and lithium battery.
Lead-acid batteries, conventional batteries, life cycle is not as good as lithium batteries, but also has memory, can not be 100% discharged, only 75% of the depth of discharge, is not recommended. Lithium batteries are divided into lithium iron phosphate batteries and ternary lithium batteries. Lithium iron phosphate batteries must be more expensive than ternary lithium. Use is the same, ternary lithium battery is recommended here. The main point is why lithium iron is not recommended, because the price of iron lithium is 1/3 higher than that of ternary lithium. As long as lithium iron is used for solar energy on the market, they are all disassembled batteries. In order to ensure the price, the life expectancy is basically not guaranteed. So, if you see that iron-lithium is cheaper than ternary lithium, you know that you must use a disassembled battery.
3. Different controllers and manufacturers have different quality. Big brands will also have problems, mainly depending on the mastery of the assembly plant's plan.
4. The lamp housing, this moisture is very large. Xiaobian's lamp is now die-cast aluminum and ABS plastic. Benevolence sees benevolence, wise sees wisdom. Die casting is better and resistant to typhoons.
Second, the classification of solar lighting solutions.
1. Constant light control time control scheme
The traditional scheme is always on. Many manufacturers make articles here. After turning on the light for 1 ~ 2 hours, the time control is adjusted to half power, and then the power is changed again after turning on. Endurance of lamps.
2. Human body induction scheme
People come all bright, people walk 10%. This configuration is reduced, costs are reduced, and battery life is extended.
Again, the category of solar lamps.
1. 5-15W induction small street lamp, this lamp is human body induction, cost-effective, of course, many businesses advertise as 20W, 40W, 60W, this is deceptive, how can a small solar panel emit 60W electricity Well, the actual maximum editor can achieve 20W, and even higher, it will overload and deceive people. This small lamp is good in rural areas and other places.
2. 20-50W induction street lamp, this lamp is human body induction. Real power, increased configuration, so that it is used in rural areas where long battery life is required, and the cost is low.
3. 20-80W conventional time-controlled light-controlled street lamp, this lamp is more commonly used products, but most manufacturers steal indicators. The solar panel is reduced a little, the battery is reduced a little, the profit is huge. The indicator can only be compared and tested, and it is difficult to see it with the naked eye.
4. 20-80W integrated solar lamp. This lamp is mostly used for export of engineering foreign trade. It is easy to install and can be lit when fixed, eliminating the cost of manual installation.
Fourth, how to identify the quality of solar lamps
1. Compare brightness and lighting time. The brightness is difficult to define with the naked eye. Only the integrating sphere can accurately measure the light effect value. The naked eye generally compares the brightness.
2. Using one stage, the basic instability program can expose problems in less than one month.
3. Disassemble the battery box, check the battery, and check whether the capacity reaches the standard. Fully charged with a charger, and then discharged with a large load, with time and discharge power, you can calculate whether the battery capacity is the specified index. At present, all battery measurements are based on full and empty, and any tester is inaccurate.
4. Comparing the size of solar panels, the basic size can also be used as a simple method to judge whether to steal indicators. Or for solar energy, measuring the current and voltage can basically calculate the power.
Integrated solar lights, solar lamps
Finally, the tricks that unscrupulous solar lamp manufacturers like to use
1. The concept of stealing replacement lamps
Praise good lamps, batteries, solar panels, and big brands of lamp beads are also divided into 369, etc., only suitable for good, at the same time using the integrating sphere to measure the light effect, you know whether it is good or not. The lithium iron battery is very good, but most of the disassembled batteries with old batteries are not better than ternary lithium. The lithium battery is protected by a protective plate and will not explode. No matter how good the solar panel is, it also divides the technology and standards made by the manufacturer. The actual measured power is the positive solution.
2. Indicators for replacing lamps
The index of the luminaire target is very large, but the actual use is very small. It is difficult to see if it is not professional, and it can only be detected with the cooperation of instruments or other manufacturers. Therefore, for every penny you pay, you should pay attention to the price difference.
3. Dumping peers
Merchants say that they are good, stepping on the quality of peer products. Don't easily believe that only actual measurement is true. Many peers have low prices, but they are actually stealing indicators. Basic manufacturers make batteries, 12V / 1AH is not less than 7 yuan, the cost can only be pulled down by stealing indicators. So don't easily believe in self-proclaiming.
In summary, good lamps can only be checked out with time. Try to choose a professional manufacturer, don't look at the scale, it depends on whether the boss knows the technology, otherwise it is not good to master the plan, the solar bomb is made.
In general, the current situation of the solar lamp market is caused by the development of the industry and the lack of supervision, and it is difficult to improve in the short term. Therefore, as the final consumer, we still have to understand and compare the consultation with multiple parties, only in this way we will not be deceived.
