What are the standards of each part of the qualified solar street light?

The solar street light consists of a light pole, a light source, a solar cell module, a battery and a solar controller. The quality judgment standards of each component are as follows: Light pole: high-quality steel, thickness ≥3.0mm, high strength, hot-dip galvanized inside and outside, surface electrostatic spraying, good corrosion resistance; color, height and specifications can be selected according to design requirements; Light source: high-power, high-brightness LED light source, light-emitting angle of more than 110 degrees, using constant voltage and constant current drive circuit, after special heat dissipation treatment, stable performance, super long service life of up to ten years, the surface lamps are made of cast aluminum, and the shape has A variety of options are available; Solar cell modules: crystalline silicon solar cell modules, with a conversion efficiency of over 17%, of which the solar cell modules are made of high-quality panel glass, low-iron, ultra-white suede tempered glass, and the light transmittance is over 90%. Low-iron ultra-white means that the iron content of this glass is lower than that of ordinary glass, thereby increasing the light transmittance of the glass. At the same time, from the edge of the glass, this glass is also whiter than ordinary glass, which is greenish from the edge. Suede means that in order to reduce the reflection of sunlight, the surface of the glass is subjected to anti-reflection treatment by physical and chemical methods, so that the surface of the glass becomes fluffy, thereby increasing the incidence of light. The purpose of tempering is to increase the strength of the glass, resist the impact of wind, sand and hail, and protect the solar cells for a long time. Effective use time of more than 25 years. Batteries: mainly 12V valve-regulated lead-acid maintenance-free batteries for solar energy, with small internal resistance, large capacity, high charge and discharge performance, and can be used safely in the working environment of -40°C to 55°C; Solar street light controller: optional It is equipped with a light-controlled/time-controlled multi-function controller, and the control time can be set at will. Perfect intelligent control system. For details, please visit: http://www.chz-lighting.com.
