Frequently Asked Questions
Schools and Educational Institutions
Can solar lights be used in cold climates?
Yes, our solar lights are designed to work in various weather conditions, including cold climates, with some models performing well at temperatures as low as -20°C.
Commercial and Industrial Parks
What maintenance is required for solar lights?
Minimal maintenance is required, typically involving periodic cleaning of panels and checking the battery and light fixtures.
Battery and Analysis
Do batteries need to be fully charged for long-term storage?
What are the possible reasons why batteries and battery packs cannot be discharged?
2) Insufficient charging or no charging;
3) The ambient temperature is too low;
4) The discharge efficiency is low. For example, when a large current is discharged, an ordinary battery cannot discharge electricity because the internal material diffusion speed cannot keep up with the reaction speed, causing the voltage to drop sharply.
What are the advantages of lithium polymer batteries? What are the advantages?
2) Can be made into a thin battery: with a capacity of 3.6V and 400mAh, its thickness can be as thin as 0.5mm;
3) Batteries can be designed in various shapes;
4) The battery can be bent and deformed: the polymer battery can be bent up to about 900 degrees;
5) Can be made into a single high-voltage battery: a battery with liquid electrolyte can only produce a high-voltage polymer battery by connecting several batteries in series;
6) Since it is liquid-free, it can be combined into multiple layers within a single chip to achieve high voltage;
7) The capacity will be twice that of a lithium-ion battery of the same size.
What is an external short circuit and what effect does it have on battery performance?
Transportation and Highways
How do solar lights perform in areas with heavy traffic pollution?
Solar panels may require more frequent cleaning in high pollution areas to maintain efficiency, but the system's durability ensures reliable performance.
Solar Street Light Lulin
Can Lulin solar street lights be used in areas with limited sunlight?
Yes, Lulin solar street lights are equipped with high-efficiency solar panels that are capable of charging the battery even in cloudy or low-light conditions. While the performance may vary based on the amount of sunlight received, the system is designed to store enough energy to ensure reliable performance during the night, even in regions with limited sunlight.
Battery Types and Applications
What is a fuel cell? How to classify?
The most common classification method is according to the type of electrolyte. Based on this, fuel cells can be divided into alkaline fuel cells, which generally use potassium hydroxide as the electrolyte; phosphoric acid fuel cells, which use concentrated phosphoric acid as the electrolyte; proton exchange membrane fuel cells, which use concentrated phosphoric acid as the electrolyte. A fully fluorinated or partially fluorinated sulfonic acid proton exchange membrane is used as the electrolyte; a molten carbonate fuel cell uses molten lithium-potassium carbonate or lithium-sodium carbonate as an electrolyte; a solid oxide fuel cell, Solid oxides are used as oxygen ion conductors, such as yttria-stabilized zirconium oxide films as electrolytes. Batteries are sometimes classified according to battery temperature and are divided into low-temperature fuel cells (operating temperature below 100°C), including alkaline fuel cells and proton exchange membrane fuel cells; medium-temperature fuel cells (operating temperature between 100-300°C), including Bacon-type alkaline fuel cells and phosphoric acid-type fuel cells; high-temperature fuel cells (operating temperature between 600-1000°C), including molten carbonate fuel cells and solid oxide fuel cells.
Battery fundamentals and basic terms
What is the electrochemistry of lithium-ion batteries?
The main component of the positive electrode of lithium-ion battery is LiCoO2 and the negative electrode is mainly C. When charging,
Anode reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Negative reaction: C + xLi+ + xe- → CLix
Total battery reaction: LiCoO2 + C → Li1-xCoO2 + CLix
The reverse reaction of the above reaction occurs during discharge.
OEM&ODM
What is your minimum order quantity (MOQ) for OEM services?
Our standard MOQ for OEM solar lights is 100 units. For ODM or special mold development, please contact our team.
Solar Street Light Luyan
How do Luyan solar street lights reduce environmental impact?
Luyan solar street lights are an eco-friendly lighting solution because they use solar power, a renewable energy source, to generate electricity. By relying on solar energy, they eliminate the need for grid electricity, helping to reduce carbon emissions and decrease the overall carbon footprint. Additionally, the energy-efficient LED lights consume less power, ensuring that the system uses minimal energy while providing bright, reliable illumination.
