As the world prepares for international warming and sustainable living, the popularity of solar lights will only increase. The governments of several countries have begun to participate, and in some parts of the world are also providing subsidies to consumers interested in purchasing solar lighting. In fact, there have been substantial developments in LED lighting innovation and photovoltaics.
There are several advantages to using solar lighting, not just economic benefits. They are highly reliable and suitable for setup. There are two different types of solar lights, and most of them are in operation. All-in-one solar street lights and split solar street lights are very special. It is very important to understand the differences between them, so we have both benefits and disadvantages.
The battery is a very important component for the storage and power supply of the solar street lamp. It determines the service life of the street lamp and the standby time in rainy days.
Split solar street lights use lead-acid batteries, and integrated solar street lights use lithium batteries. The charging and discharging time of lithium batteries is 3 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 ℃, its capacity will be reduced. When the temperature is lower than -10°C, the electrolyte will freeze 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℃-30℃, the capacity will be reduced by 30%.
Therefore, we can see that the integrated solar street light has a longer service life and has better performance when the temperature is lower.
Installation speed will affect the installation cost of the project.
From the installation diagram above, we can see that to install split solar street lights, we need to dig some pits for storing cages and batteries. Then, we need to install solar panels, lights, repair all kits, after all these kits, we still have to wire internally to make the whole system work properly.
For the integrated solar street light, only 3 simple installation steps are required: dig the cage-fix the screw of the light-erect the pole to complete the installation.
We have to spend about 1-1.5 hours to install split solar street lights. For integrated solar street lights, solar panels, LED lights, batteries, smart sensors and controllers are all integrated in one box, which is very easy to install. They can be installed on new or old poles, even on walls. It helps to save a lot of installation time and cost.
The cost involves two parts. The first is the cost of the installer. Through the analysis of the above paragraphs, we know that the longer the installation time, the higher the cost of workers. In this regard, both project owners and construction contractors tend to choose a lower cost method.
The other part of the cost is related to product materials. The gel battery used for split solar outdoor lights is bulky.
For example, an 80W street lamp uses a 150A/H battery, which must be matched with a 300W solar panel.
On the other hand, the lithium battery used for the 80W integrated solar lamp is 40~70A/H, which is small and can be built-in. The corresponding 36V 120W~130W solar panel specifications can meet the needs of use. It can be clearly seen that the price of a solar panel with the same wattage used by an integrated solar lamp is half the price of a split type.
The split solar lamp uses a large-capacity colloidal battery, which can provide 100% brightness all night. But the question is, how many people will show off in the early hours of the night? From this point of view, the 100% brightness output configuration in the second half of the night is a waste.
Integrated solar lanterns usually use smart controllers. Based on big data analysis and human flow judgment, the controller can intelligently adopt time control and/or human induction mode. It can be set to provide 100% brightness output when there are too many people, and automatically switch to the human body sensing mode when there are few people or no one. These lights have an infrared sensor function, which can be automatically turned off during the day and turned on once when the night falls after charging.
They can also sense within a distance of 7 to 10 meters, and detect movement to automatically adjust its brightness.
In this way, it will achieve lighting effects, save electricity, and contribute to environmental protection.
Compared with all integrated solar street lights, split solar street lights are more flexible. The solar panel can be adjusted according to the sunlight to absorb the maximum heat, but if the solar panel has insufficient sunlight, it can work for a shorter time.
Since the solar panels are not fixed in the traditional split solar panels, you can use any size panel to store more electricity so that it can be used for longer nights in winter. However, in general, it is limited by the size of the luminaire.
Since these solar panels are installed on lighting fixtures, they are not very flexible compared to traditional solar street lights.
Since they are wireless, these lights can be installed at entrances, periphery, paths, parking lots, playgrounds, courtyards and even remote areas.
The one-stop solar street is lighter in weight, compact in structure, stylish in design, and added value for money.
Always choose an all-in-one system because they are rust-proof, waterproof, maintenance-free, shock-proof and have low power consumption.
The total installation cost of traditional solar street lights will be about 40%-60% higher than all-in-one integrated solar street lights.
It seems that investing in all-in-one solar street lights can bring you the greatest benefit. Although the initial investment seems to be high, in the long run, even in large-scale use, this kind of lighting can still provide a longer life cycle. Compared with old-fashioned street lights, modern all-in-one solar integrated lights have a very small risk of overheating because they have no external wires, which also minimizes the potential for accidents.
