How to distinguish the quality of solar street lamp panels?
As a new energy source, solar energy has the advantages of safety and no hidden dangers, energy saving and no consumption, environmental protection, easy installation, automatic control and maintenance, etc. Therefore, solar street lights have been widely used in road lighting. Solar street light is composed of LED light source (including driver), solar panel, battery, solar street light controller, street light pole (including base) and auxiliary materials and wires. Today we are mainly talking about solar panels. Solar panels are the main factor that directly affects the efficiency of solar street lights to absorb light energy. Let’s teach you how to distinguish the quality of solar street light panels.
1. Look at the conversion rate: a high conversion rate is the guarantee of stable income! This conversion efficiency is invisible on the surface, and the component parameters need to be compared.
2. Look at the welding process: see if there is any missing welding during the string welding of the cells, this can be seen directly from the appearance.
3. Look at the solar street light manufacturers: look at the component suppliers, whether they are mainstream brands in the industry, and the quality assurance and after-sales service of large-brand components are guaranteed.
4. Look at the quality of the frame: Is it strictly rectangular? Is the error too large?
5. Look at the quality of the pressure on the back: whether there is any unevenness in the pressure, or bubbles, wrinkles, etc. It is not difficult to find bubbles and wrinkles, they can be seen in the sun.
