All you should know about solar lights-8 Q&A Collection
What does solar lights mean?
Solar lights amazon are electric lights that are converted into electrical energy by solar panels. In the daytime, even in cloudy days, this solar generator (solar panel) can also collect and store solar energy. As a new kind of safe and environmentally friendly electric light, solar light has attracted more and more attention.
How do solar lights save money?
Solar lights amazon use clean renewable energy, which can reduce carbon dioxide emissions compared to traditional high-pressure sodium lights. If all 20 million street lights are converted to solar street lights, 25.8 million tons of carbon dioxide emissions can be reduced, which is equivalent to 10.3 billion US dollars in carbon dioxide emission reduction costs. Therefore, investing in the solar street light industry can produce greater social benefits. From the perspective of economic benefits, according to forward-looking calculations, based on 4m street lights and 8m street lights, after using solar street lights, 4m street lights and 8m street lights save about 2,190 kWh of electricity each year.How do solar lights function?
The working principle of the solar light is simple. The solar cell is made by using the photovoltaic effect principle. During the day, the solar cell panel receives solar radiation energy and converts it into electrical output. It is stored in the battery through the charge and discharge controller. At night, when the illumination is gradually reduced to about 101ux, The open circuit voltage of the solar panel is about 4.5V, the charge and discharge controller will act after detecting this voltage value, and the battery will discharge the lamp cap. After the battery is discharged for 8.5 hours, the charging and discharging control action, and the battery discharge is over. The main function of the charge and discharge controller is to protect the battery.What are the advantages about solar lights?

Are solar lights as good as wired lights for exterior home landscape lighting?
Solar street lights amazon are quite different from ordinary wired lights The main differences are as follows. The advantages of solar lights are very obvious.
1. The components are different. Solar street lights are composed of solar panels, solar panel brackets, lamp holders, light sources, solar street lamp controllers, batteries, lamp poles and ground cages; ordinary wired lights are composed of lamp holders, light sources, controllers, lamp poles, Consists of external cables and ground cages.
2. The energy supply is different. The main energy supply of solar street lights comes from the electric energy converted by sunlight during the day, while the different ordinary wired lights mainly rely on external mains power.
3. The current and voltage are different. The DC power used by solar street lights is only 12V or 24V, which does no harm to people.Ordinary wired lights use AC power with voltages of 220V and 380V, which is very harmful to people, especially when spontaneous combustion occurs. Disasters or long periods of non-maintenance may cause leakage.
4. The installation method is different. The installation of solar street lights is simple. Like lithium solar street lights, you only need to dig a foundation pit and then assemble the last vertical pole on site. The installation method of ordinary wired lightsis very complicated. In addition to the foundation pit, cable ducts must be dug. , Backfilling, assembling lights, layout systems, etc.
5. The control methods are different. Each solar street light is a separate system, and all components are in or on the light pole; ordinary wired lights need several lights to establish a control room, which is controlled by the control room.
6. Repairs and maintenance are different. If the solar street lamp is damaged, repair the other, and the rest will not be affected. Routine maintenance is not required; if an ordinary wired lights is damaged, in addition to checking the damage, it is necessary to check the entire circuit and control room for more repairs. Complex and require regular maintenance to avoid leakage accidents.
How to install solar street lights?
How to determine the installation location of solar street lights?
The installation of solar street lights amazon in several steps, digging pits, assembling, and poles are simple and convenient. Each step is broken down into a small project, and sometimes you may not know where to start. For example, when digging a foundation pit, you have to consider how big and deep the pit needs to be. There is a scientific assembly sequence when assembling the lamps and lanterns. Then it will be much smoother. Ignoring some small details may also cause the lamps to not light up. Remember these installations. Standard, easy to install street lights. Today's Xingchi New Energy solar street light manufacturers summarize and organize to share with you:
1. Determine the installation location
The installation site should avoid the shadow of obstacles such as houses, trees, etc., so as not to reduce the power generation efficiency of solar panels and cause short working hours. If you are in the northern hemisphere, when installing the "solar integrated street light", make the solar panels face the south or the direction with a better light-receiving surface as much as possible to obtain the maximum energy. If it is in the southern hemisphere, it is better to make the solar panels face north or the light-receiving surface when installing. According to actual engineering needs, choose the best installation location and install solar street lights along the road.
2. Mining the foundation
Determine the size of the excavation according to the requirements. The foundation construction should first follow the requirements of local laws and regulations and geological surveys. If the surface is soft soil, the excavation depth should be deepened.
3.install street lights
1. Except the packaging and check the accessories;
2. Connect the external waterproof connector to test whether the light can work normally;
3. The rear seat of the lamp is fixed at the appropriate height of the lamp post;
4. Please clean up the dirt on the surface of the solar panel in time after installation, and be careful not to block the solar panel with objects.
5. Complete installation and regular maintenance
4. pouring street lamp base
After curing for 2-4 days, proceed to the next step. During the concrete curing process, it should be watered and maintained regularly, and can be installed after the concrete is fully cured.
In order to ensure aesthetics and the battery pack can better receive solar energy, the dust, leaves or other impurities on the battery pack can be cleaned every six months. In areas with severe dust or harsh environment, maintenance frequency can be appropriately shortened.
How to install solar street lights? The above is about the assembly process of solar energy-saving street lights.

At the same time, solar smart street lights are easy to install and transport
What are the best outdoor solar lights?
How to choose solar lights and lamps correctly to avoid risks
The solar energy market is now mixed with jade and dragons, true and false. Today, I will explain to you how to buy suitable solar lamps.
1. The composition of solar lights amazon.
1. Solar panels are divided into 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 the same concept, but the volume of polycrystalline silicon will be larger.
2. The battery energy storage part is divided into two types: traditional lead-acid gel maintenance-free battery and lithium battery.
Lead-acid batteries, conventional batteries, have a life cycle inferior to that of lithium batteries. They also have memory properties. They cannot be discharged at 100%, and have only 75% depth of discharge. It is not recommended now.
Lithium batteries are divided into lithium iron phosphate batteries and ternary lithium batteries. Lithium iron phosphate batteries must be more expensive than ternary lithium batteries. The use is the same, and a ternary lithium battery is recommended here.
The key point is why iron-lithium is not recommended, because the price of iron-lithium is 1/3 higher than that of ternary lithium. As long as the solar energy is made of iron-lithium, they use disassembled batteries. Old batteries are only used for disassembled batteries. In order to guarantee the price, the life span is basically not guaranteed. So, if you see that iron-lithium is cheaper than ternary lithium, you know that it must be a disassembled battery.
3. The quality of the controller is different from different manufacturers. Big brands also have problems, mainly depending on the mastery of the plan of the assembly plant.
4. The lamp housing has a lot of moisture. This lamp of the editor now has die-cast aluminum and ABS plastic materials. The benevolent see benevolence, and the wise see wisdom. Die-casting is better and resistant to typhoon.
2. Classification of solar street lamp schemes.
1. Constant light control time control scheme
The traditional solution is always on. Many manufacturers are making a fuss here. After the light is turned on for 1 to 2 hours, the time control is adjusted to half power, and then the power is turned on again for a while. This can be extended if the hardware indicators are not up to the standard. The life of the lamp.
2. Human body induction scheme
People come all light, people go 10%. In this way, the configuration is reduced, the cost is reduced, and the battery life is extended.
Third, the category of solar street lights.
1. 5~15W induction small street light, this light is human body induction, cost-effective, of course, many businesses advertise as 20W, 40W, 60W, this is a lie, how can a small solar panel generate 60W of electricity Then, the actual maximum editor can achieve 20W, no matter how high it is, it will be overloaded. This small lamp is good for rural areas and other places. It is to ensure that electricity is generated toward the sun.
2. 20~50W induction street lamp, this lamp is human body induction. The real power is increased in configuration, so it is used in rural areas where long battery life is required, and the cost is also low.
3. 20~80W conventional time-controlled light-controlled street lamps, this lamp is a more common product, but most manufacturers steal the indicators. The solar panels are reduced a little and the batteries are reduced a little, and the profits are huge. The indicators can only be compared and tested, and it is difficult to see with the naked eye.
4. 20~80W integrated lamps. This lamp is mostly used for engineering foreign trade export. It is easy to install and can be lighted when fixed, saving manual installation costs.
Fourth, how to identify the quality of the product
1. Compare brightness and lighting time. The brightness is difficult to define with the naked eye, and only the integrating sphere can accurately measure the light effect value. The brightness is generally lower to the naked eye.
2. Using one stage, the basic unstable solution can expose the problem in less than one month.
3. Open the battery box and look at the battery. Check whether the capacity is up to standard. Fully charge with a charger, and then discharge with a large load. With time and discharge power, you can calculate whether the battery capacity is the specified index. All battery measurements nowadays are based on being fully charged and empty. No tester is accurate.
4. Comparing the size of solar panels, the basic size can also be used as a simple method to judge whether to steal the index. Or when facing solar energy, measuring current and voltage can basically calculate power.
