Solar panels, also known as solar chips, are photoelectric semiconductor chips directly generated by sunlight. It plays a huge role in all fields of current energy and has been widely used. Next, Xiaobian will temporarily introduce how to identify the quality of solar panels and solar pv cable for you. I hope it will be helpful to you.
1. Look at the front
The surface of tempered glass needs to be looked at carefully, something that some solar panel manufacturers don't pay attention to. The stains on the surface should be cleaned in time, otherwise the efficiency of the battery will be affected.
2. Look at solar cells
In order to save costs, numerous irregular manufacturers even assemble damaged solar cells into what look like complete solar cells. In fact, there are huge risks. I may not see the problem early, but using it for a lengthy time is easy to break. Affect the whole solar panel. When the temperature is too steep, there will be a fire phenomenon, threatening people's safety.
3. Look at the back
The design of the back of the solar panel should indicate the safety technical parameters, such as: open output voltage, short circuit fault current, working voltage, etc., and then depend on the pressure effect control panel on the back of the solar panel. If a large number of bubbles or wrinkles appear after being pressurized, the solar panels are classified as unqualified.
4. Look at the junction box
The junction box is a kind of connector of the solar cell module. Its main function is to output the electric energy generated by the solar cell module manufactured by the cable through the cable. The strength of the junction box is also related to the efficiency of the solar panel. The junction box cover is firmly attached to the junction box, and the outlet lock head should turn freely and be tightened.
When buying solar panels, be sure to pay attention to the above four points. In addition, we must be able to choose according to the configuration we need.
