12 m solar lighting standards

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

the yulong solar market now is mixed, it is true, is false. Today, shandong solar street lamp lighting factory will introduce the composition of solar lamp. 1. The composition of solar lamp. 1. Divided into monocrystalline silicon and polycrystalline silicon solar panels. Higher conversion efficiency of monocrystalline silicon and polycrystalline silicon conversion efficiency is lower than that of single crystal silicon. But when it comes to power, 100 watts of monocrystalline silicon and 100 watts polycrystalline silicon is the same 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. Traditional lead-acid batteries, battery, in the life cycle than lithium-ion batteries, and have a memory, not 100% discharge, but only 75% of the depth of discharge, so now is not recommended. 3. The quality of the controller by manufacturer. Big brands will also have a question, mainly depends on the mastery of assembly solutions. 4, lamp shell, the water is very large. Shaw lamp now is to use aluminum material and ABS plastic die casting. In addition, solar street lamp manufacturers in shandong are briefly introduced how to determine the quality of the product. First of all, the more brightness and illumination time. Brightness is difficult to define with the naked eye, integrating sphere is the only accurate measuring light efficiency value. Brightness and roughly equivalent to the naked eye. Secondly, compare the size of solar panels, basic size also can be a simple way to determine whether to cut corners. Or solar, measuring current and voltage, basically computing power.
