Solar led street lamp manufacturer to teach you how to correct purchase

The composition of solar LED street light. 1, solar panels, divided into two kinds of monocrystalline silicon and polycrystalline silicon, monocrystalline silicon conversion efficiency is high, polysilicon conversion efficiency is lower than that of the single crystal silicon. But when it comes to power, monocrystalline silicon and polycrystalline silicon of 100 w, 100 w is a concept, just the volume of a polysilicon

solar led street lamp. 1. Solar panels are divided into monocrystalline silicon and polycrystalline silicon, monocrystalline silicon conversion efficiency is higher, the polysilicon conversion efficiency is lower than single crystal silicon. But when it comes to power, 100 watts of monocrystalline silicon and 100 watts polycrystalline silicon is a concept, in addition to the volume of a polysilicon will be bigger. 2. Battery energy storage is divided into two types: the traditional lead-acid battery and lithium battery. Lead-acid batteries, batteries, life than lithium-ion batteries, and memory, can't discharge 100%, just 75% of the depth of discharge, not recommended to use now. Lithium battery into battery and lithium iron phosphate ternary lithium battery. Lithium iron phosphate battery certainly is more expensive than the ternary lithium. Purpose is the same. Here we recommend the ternary lithium battery. The key is why we do not recommend lithium iron. Due to lithium iron price is a third higher than ternary lithium, as long as lithium iron on the market for solar energy, they are made by remove the battery, old batteries and remove the batteries, so that we can guarantee the price and life. So, when you see the lithium iron is much cheaper than lithium ternary battery, you will know that it must be a removable battery. 3, controller, different, different quality. Main brands also have problems, mainly depends on the overall planning of assembly. 4, lamp shell, the water is very large. The lamp is made up of small pieces, and now is made of die-casting aluminum and ABS plastic. Different people have different views on the same thing. Die casting is better, resistance to the typhoon. Street lamp material led street lamp manufacturers of solar street light products have special team of after-sales service guarantee.
