How many years is the life of the lithium battery for solar street lights

Now most of the solar lithium batteries on the market are divided into two kinds, one is the ternary lithium battery, the general service life is about 5 years, in fact, the number of cycles is generally within 1000 times, generally after 3 years the battery capacity will gradually decrease, and then the attenuation is very serious. There is also a lithium iron phosphate battery, and the number of cycles is in.

About 2000 times, but the low temperature effect of lithium iron phosphate batteries is very poor, and it is generally best used in high-temperature areas, with a life span of about 6-8 years.

First of all, the application of solar street lights mainly relies on solar panels, and usually the voltage of solar panels is 17.

5V and 36V are the two mainstream voltage specifications on the market. Why is it talking about the voltage of this solar panel? This is because of the voltage design of the solar panel, which charges 12V and 24V batteries respectively.

Of course, you can also connect multiple batteries in series, so that the solar panels can also be connected in series for charging.

The solar panel generates direct current, and after charging into the battery, the voltage of the battery is of course 12V, 24V, and 36V, which are several specifications commonly used in solar street lamps.

At present, the light source of solar street lights on the market is specially designed for making solar panels, so the conventional voltage is, 12v 24v 36 This is the mainstream, of course, there are higher ones, such as 48v 72v and so on.

Of course, lithium batteries are battery packs that can be connected in series into several times the voltage, but solar street lights generally have 12V24V.

How long is the lifespan of solar source lights? The life of solar street lights is affected by solar panels, lithium batteries, and street lights.

The controller and the LED light source decide.

Normal service life of solar panels: more than 20 years.

Lithium battery life of solar street lights: more than 5 years.

LED light source service life: more than 50,000 hours.

Solar street light controller: more than 3 years.

On the whole, there is no problem with solar street lights for 4-5 years, and the warranty of solar street lights of most manufacturers is 3 years, which is mainly related to the street light controller.

Solar street lights.

The lifespan of the BAI is mainly determined by the solar panels of the solar street lamp, the storage DAO pool and the LED light source.

Actually, these parts are answered.

It's working all day, and there's an electric current passing through.

The normal service life of solar panels can reach about 25 years, the battery is expected to attenuate, the normal service life is 5-8 years, and the LED light source is of good quality and the installation and wiring are correct, and there is no problem with 10 years. The battery of the solar street lamp can be replaced, and the battery life can be used normally when it is replaced with a new battery.

Actually, there are a lot of them now.

The quality of the street lamp that bai uses electricity

It's not good, because of long-term exposure to air, DAO has endured bad weather from wind and sun, so its wiring, lampshades, and even light bulbs will be greatly affected. At present, the use of high-tech and technology research and development of this kind of solar street lamp, the solar cells used are made of good technology that can ensure that the performance will not be reduced for more than 10 years, and some of the best solar modules can even generate electricity for more than 25 years.

It can be used, and two 30 watts can be attached.

There shouldn't be any problem.

Why don't you light up.

Hold on. It's a bit big, you choose a 30w one to try.

I lit it up with a light bulb on the battery.

How many volts is your battery?

It is estimated that the current is too small.

Your battery has a lot of current.

If your battery is also 12 pays, it means that you have a problem with the solar battery.

The lifespan of solar street lights is about ten years. Solar energy is an inexhaustible, clean, pollution-free and renewable green and environmentally friendly energy. Using solar power generation, incomparable cleanliness, high safety, relative breadth and sufficiency of energy, long life and maintenance-free and other advantages that other conventional energy sources do not have, photovoltaic energy is considered to be the most important new energy in the 21st century.

Principle:

The working principle of solar street lamp: under the control of the intelligent controller during the day, the solar panel is irradiated by the sun, absorbs the solar light and converts it into electricity, the solar cell module charges the battery pack during the day, and the battery pack provides power to the LED light source at night to realize the lighting function.

The DC controller can ensure that the battery pack is not damaged due to overcharge or overdischarge, and has the functions of light control, time control, temperature compensation, lightning protection, reverse polarity protection and so on.

How long do solar street lights last?

The sales of solar street lamps are rising rapidly, and many rural areas regard solar street lights as an important choice for outdoor lighting. However, there are still many people who are worried about its service life, thinking that it is a new type of product, the technology is not mature, and the service life is short. Even if solar street lamp manufacturers give a three-year warranty, there are still many people who have concerns about this.

Today, the technician of the solar street lamp manufacturer will take you to scientifically analyze how long the service life of the solar street lamp can reach.

Solar street light is an independent power generation lighting system, which is composed of batteries, street light poles, LED lamps, panels, solar street light controllers and other components. There is no need to connect to the mains, and the light energy is converted into electricity through the solar panel during the day and stored in the solar battery, and the battery supplies power to the LED light source at night to make it glow.

1. Solar panels.

We all know that solar panels, it is a complete set of power generation equipment, it is composed of silicon wafers, and the service life is very long, which can reach a life of about 20 years.

Second, LED light source.

The LED light source is composed of at least dozens of lamp beads containing LED chips, with a theoretical life of 50,000 hours, and the normal life can reach about 10 years.

3. Street lamp poles.

The street lamp pole is made of Q235 steel coil rod, and the overall hot-dip galvanizing treatment has strong hot-dip galvanizing anti-rust and anti-corrosion ability, so at least 15 are guaranteed not to rust.

Fourth, the battery.

At present, the main batteries used in domestic solar street lamps are colloidal maintenance-free batteries and lithium batteries. The normal service life of gel batteries is 6 to 8 years, and the normal service life of lithium batteries is 3 to 5 years. Some manufacturers guarantee a gel battery life of 8 to 10 years, and a lithium battery life of at least 5 years, which is completely exaggerated.

In normal use, 3 to 5 years is the time to replace the battery, because the actual capacity of the battery in 3 years and 5 years is much lower than the initial capacity, affecting the lighting effect, replacing a battery is not too high, and then buy it from the solar street lamp manufacturer.

5. Controller.

Generally, the controller has a high waterproof sealing level, and there is no problem with normal use for several years.

In general, the key to the service life of solar street lamps lies in the battery, when buying solar street lights, it is recommended to configure the battery to be larger, the life of the battery is his cycle discharge life, the complete discharge is about 400 to 700 times, if the capacity of the battery is only enough to discharge every day, then the battery is easily damaged, but the capacity of the battery is several times the daily discharge, that means that there can be a cycle in a few days, which greatly increases the life of the battery. Moreover, the capacity of the battery is several times that of the daily discharge, which can ensure that the continuous rainy days are longer.

The service life of solar street lamps also lies in the necessary maintenance at ordinary times, in the early stage of installation, it is necessary to strictly follow the construction standards, and try to make reasonable matches in the configuration, increase the capacity of the battery, so as to extend the life of solar street lights.

Let's take the most general street lamp on the side of the road as an example, his life span is only about five years, because the lamp is not LED, so it is easy to damage, and it will be broken in five years.

I have been in the lighting industry for 10 years, solar lamps and lanterns mainly look at the battery and solar panels, the battery has an aging problem, this problem is difficult to solve, basically a lamp with two years is no problem, the solar panel is just to charge the battery, this solar panel has no problem for 3-5 years, the general solar street lamp, less than 50 ampere battery, 1 ampere = 1000 mAh capacity, the brightness in the second half of the night is very low, now the online wattage is too serious, a lamp standard of several kilowatts, If you really have that much wattage, your battery capacity is so small, how long can it be on?

The life of the solar street lamp depends on his accessories, the life of his accessories is not the same, the longest life of the solar panel can reach 25 years, the life of the light pole has 10-12 years, the normal life of the light source has 5-7 years, the life of the lithium battery has 3-5 years, after which the battery will have a certain capacity attenuation, although it can also work normally, but the light time and brightness will have a certain impact.

At present, there are two main packaging forms of solar cells, lamination and dispensing.

The lamination process can ensure that the working life of the solar cell is more than 25 years, although the epoxy glue is beautiful at that time, the working life of the solar cell is only 1 2 years. Therefore, for low-power solar lawn lights below 1w, in the absence of excessive life requirements, you can use the epoxy packaging form, and for the solar lamps with a specified service life, it is recommended to use the laminated packaging form. In addition, there is a silicone gel used to encapsulate solar cells with drops, and it is said that the working life can reach 10 years.

Solar Garden Light Life—Solar Garden Light Battery Capacity.

It's time to pick and choose.

Due to the solar photovoltaic power system.

The input energy is extremely unstable, so it generally needs to be equipped with a battery system to work, and solar lamps are no exception, and the battery can only work. Generally, there are lead-acid batteries.

NI-CD batteries, NI-H batteries, their capacity selection directly affects the reliability of the system and the system**. The selection of battery capacity generally follows the following principles: firstly, on the premise of being able to meet the night lighting, the energy of the solar cell module during the day should be stored as much as possible, and at the same time, it should also be able to store the electrical energy that meets the needs of continuous rainy night lighting.

The battery capacity is too small to meet the needs of night lighting, and the battery capacity is too large, on the one hand, the battery is always in a state of power loss, which affects the life of the battery and causes waste at the same time.

It can be seen that the influence of solar cells on the use time of solar garden lights is still relatively large, which reminds users that if they want to make solar garden lights use for a long time, then they should try to choose a battery with a good closed form of solar cells and a relatively ideal battery capacity, and it is also necessary to use solar garden lights in a scientific and reasonable way, so as to extend their use time.

Solar street lights use LED power supply, the biggest feature of LED light source is that it has a long life, up to 50,000 hours, assuming that it is used for ten hours a day, then the life span is at least 10 years.

In fact, the quality of many street lamps that use electricity is not good, because they are exposed to the air for a long time and withstand the bad weather of wind and sun, so their wiring, lampshades, and even bulbs will be greatly affected. At present, the use of high-tech and technology research and development of this kind of solar street lamp, the solar cells used are made of good technology that can ensure that the performance will not be reduced for more than 10 years, and some of the best solar modules can even generate electricity for more than 25 years.

Look at the material and quality you bought, I bought the solar lamp of Four Seasons Muge, The reason why I like it is that I know that Four Seasons Muge itself specializes in solar energy. If you're satisfied, give it a big thumbs up.

Using automotive-grade power cells, the lithium battery life of solar street lights is more than 15 years.

In recent years, lithium batteries are not like at the beginning, there are only energy storage level lithium batteries, and the battery life of energy storage level is only 3-8 years, like the 18650 ternary battery cells on the market, only 200-300 cycles, which is similar to the lead-acid battery life, only 2-3 years. The 32650 battery cells at the energy storage level can grow for 4-5 years.

Nowadays, many car batteries are used in echelons, and high-end solar street lamp manufacturers of high quality directly take new car cells to make the life ratio of lithium batteries for solar street lights. Good echelon power battery, more than 1000 cycles, more than 10 years of life.

There are also lithium iron and lithium power that are now powered, such as BYD C20 cells, which have a charge and discharge of 70% at -20 degrees. Our factory has been using lithium battery solar energy in Xinjiang, Inner Mongolia and Qinghai for 3 winters, and there is no after-sales service.
