Solar street lamps manufacturer's profit space and the relationship between the market price dynamic | | industry lighting: solar led street lamp manufacturers in the countryside2

Solar market now mixed yulong, true artificial, shandong solar street lamp factory lighting lamps manufacturer to you today about the solar lamps and lanterns of what. A, solar lamps and lanterns. 1, solar panels, divided into monocrystalline silicon and polycrystalline silicon

solar market now is a combination of jade and dragon, true and false. Today, solar street lamps factory in shandong street lamps factory will explain to you the composition of solar lamp. A, solar 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, but the volume of a polysilicon will be bigger. 2. Battery energy storage is divided into two types: traditional lead-acid gel and maintenance-free battery and lithium battery. Lead-acid batteries, batteries, life than lithium-ion batteries, has the memory at the same time, the discharge is not 100%, only 75% of the depth of discharge, is not recommended. 3, controller, different manufacturers, different quality. Main brands also have problems, mainly depends on the overall planning of assembly. 4, lamp shell, the water is very large. The little lamp is made from die-casting aluminum and ABS plastic now. In addition, solar street lamp manufacturers in shandong are briefly introduced how to determine the quality of the product. First comparative brightness and illumination time. The brightness is difficult to define with the naked eye, integrating sphere is the only accurate measurement of luminous efficiency value. To the naked eye is compared commonly brightness. Second, compare the size of solar panels, basic size can also act as a simple judgment method to steal. Or for solar, measuring current and voltage, we can calculate the power basically.
