Solar street light manufacturers teach you how to choose solar street lights correctly

The composition of solar street light. 1. Solar panels are divided into two types: 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 a concept, but the volume of polycrystalline silicon will be larger. 2. The energy storage part of the battery is divided into two types: traditional lead-acid colloid-free protection battery and lithium battery. Lead-acid batteries, conventional batteries, the life cycle is not as good as lithium batteries, but also has memory, can not be 100% discharge, as long as 75% of the 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 the 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 iron-lithium is used for solar energy in the market, it is used to disassemble the battery, and the old battery only needs to use the disassembled battery. Only the price can be guaranteed, but the lifespan cannot be guaranteed at all. Therefore, when you see that iron lithium is cheaper than ternary lithium, you know that it must be a disassembled battery. 3. Controllers, manufacturers are different, the quality is different. Big brands will also have problems, which mainly depends on the planning mastery of the assembly plant. 4. The lamp shell has a lot of moisture. This light fixture of the editor is now made of die-cast aluminum material and ABS plastic material. The benevolent sees benevolence, and the wise sees wisdom. Die-casting is better, resistant to typhoons. The solar street light products produced by solar street light manufacturers are guaranteed and have a dedicated after-sales service team.
