Splitted solar street light VS integrated solar street lights

Splitted solar street light VS integrated solar street lights

As the world prepares for international warming and sustainable life, the popularity of solar lamps will only increase. Governments in several countries have begun to participate, and they have also provided subsidies to consumers interested in buying solar lighting in some parts of the world. In fact, in the LED lighting innovation and photovoltaic fields have developed substantial development.

There are several advantages to use solar lighting, not just economic benefits. They are highly reliable and suitable for settings. There are two different types of solar lights, most of them are running. One more solar street lights and split -type solar street lights are very special. It is very important to understand the differences between them, so we have beneficiated and disadvantages.

Lithium battery VS lead -acid battery?

The battery is a very important component for the storage and power supply of solar street lights. It determines the service life of street lights and standby time for rainy days.

The split solar street lights use lead -acid batteries, and integrated solar street lights use lithium batteries. The charging and discharge time of lithium batteries is three times that of lead-acid batteries, so lithium batteries have a longer service life (now TachyonLight uses highly efficient Lifepo4, which is more stable and has a service life of 5-6 years).

For lead -acid batteries, when the temperature is lower than 5 ° C, its capacity will be reduced. When the temperature is below -10 ° C, the electrolyte will be frozen and the battery will temporarily fail. For lithium batteries, when the temperature is not lower than -20 ° C, it can work well and the capacity will not decrease. When the temperature is lower than -20 ° C-30 ° C, the capacity will be reduced by 30 %.

Therefore, we can see that integrated solar street lights have a longer service life and have better performance when the temperature is low.

Install

The installation speed will affect the installation cost of the project.

From the installation diagram above, we can see that to install a split solar street light, we need to dig a pit for storing cages and batteries. Then, we need to install solar panels, lighting lights, and repair all suits. After all these kits, we must still wrap the internal wiring to make the entire system work normally.

For integrated solar street lights, only 3 simple installation steps are required: digging-screws of fixed lights-vertical rods to complete installation.

We must spend about 1-1.5 hours to install a split solar street light. For integrated solar street lights, solar cell panels, LED lights, batteries, smart sensors and controllers integrated in a box, it is very easy to install. They can be installed on a new rod or an old rod, even if the walls are available. It helps save a lot of installation time and cost.

cost

Costs involve two parts. The first is the cost of installing workers. Through the analysis of the above paragraphs, we know that the longer the installation time, the higher the cost of workers. In this regard, project owners and construction contractors tend to choose a lower cost method.

Another part of the cost is related to product materials. The gel battery for split solar outdoor lamps is huge.

For example, the 80W street lights use a 150A / H battery, which must match the 300W solar panel.

On the other hand, the lithium battery for 80W integrated solar lamps is 40 ~ 70A / h, which is small and can be built. The corresponding 36V 120W ~ 130W solar panel specifications can meet the needs of use. It can be clearly seen that the price of solar panels that use the same watt counts used in integrated solar lamps is half of the price.

intelligent control

The split solar lamp uses a large -capacity collagen battery, which can provide 100 % brightness all night. But the problem is how many people will show off in the early morning of the night? From this perspective, a 100 % brightness output configuration in the middle of the night is a waste.

Integrated solar lanterns usually use smart controllers. Based on big data analysis and flow judgment, the controller can intelligently adopt time control and/or artificial induction mode. It can be set to provide 100 % brightness output when there are many people, and automatically switch to the human body induction mode when there are fewer people or no one. These lights have infrared sensing functions, which can be automatically turned off during the day, and opened temporarily at night after charging.

They can also perform sensing within a distance of 7 to 10 meters, and detect the motion to automatically adjust their brightness.

In this way, the lighting effect will be achieved, saving electricity, and contributing to environmental protection.

Other comparison:

Splitted solar street lights:

Compared with all integrated solar street lights, the split solar street lights are more flexible. The solar panel can be adjusted according to the sunlight to absorb the maximum calories, but if the sunlight of the solar panel is insufficient, it can work a shorter time.

Because solar panels are not fixed in the traditional split solar panels, you can use any size of a battery board to store more electricity so that you can use longer in winter night. However, in general, it is limited by the size of the lamp.

One more solar street light:

Because these solar panels are installed on lighting fixtures, they are not very flexible compared to traditional solar street lights.

Because they are wireless, these lights can be installed on the entrance, periphery, small roads, parking lots, playgrounds, courtyards and even remote areas.

One -stop solar streets are lighter, tight in structure, fashionable, and increased money.

Always choose an integrated system, because they are rust, waterproof, maintenance -free, shockproof and low power consumption.

The total cost of the traditional solar street lights will be about 40 % -60 % higher than the multi -integrated solar street lights.

Investing in a multi -in -one solar street light seems to bring you the biggest benefit. Although the initial investment seems to be very high, in the long run, even if it is used in large quantities, this lighting can still provide a longer life cycle. Compared with the old -fashioned street lights, because there is no external wires in Hyundai’s multi -combined solar integrated lights, it has a very small risk of overheating, which also minimizes the hidden dangers of the accident.
