How to judge the good and bad of solar panels

Solar panels, also known as solar chips, are photoelectric semiconductors generated directly from sunlight. Solar energy is a green and sustainable new energy. Various fields are actively developing the application of solar energy, and in many areas, solar panels are currently playing a huge role and are widely used. Of course, with the development of solar energy applications, the solar panel market is also gradually expanding. The market is large and will inevitably have some uneven product problems. In this article, Findy Solar, a professional solar panel manufacturer, will share the methods to identify good and bad solar panels.

 

To determine the good or bad of solar panels, we can observe from four aspects.

• Front side

• Battery

• Backside

• Junction box

 

1. Look at the front 

Need to look carefully at the surface of the tempered glass, which is where some solar panel manufacturers do not pay attention. The stains on the surface should be cleaned up in time. Otherwise, it will affect the efficiency of the battery.

 

2. Look at the battery

Many irregular manufacturers even assemble damaged solar cells into seemingly complete cells to save cost. There is a great risk. Problems that may not be seen in the early stage but it is easy to break down after a long time of use. Affect the entire solar panel. When the temperature is too high, a fire will threaten people's safety.

 

3. Look at the back

Solar panel back design should be marked with technical safety parameters, such as open-circuit output voltage, short-circuit fault current, operating voltage, etc., and then depends on the solar panel back pressure effect control board. If any bubbles, wrinkles, and other traces appear after pressurization, then this type of development solar panels are classified as unqualified. Battery panel

 

4. Look at the junction box 

A junction box is a kind of connector for a solar cell module. Its main role is to manufacture solar cell module-generated electricity through the cable's output. Whether the junction box is solid is also related to the efficiency of solar panels. The junction box cover and junction box firmly fit, and the outlet lock should turn freely and tighten.

 

When you buy epoxy solar panels, you can pay attention to the above 4 points. This way, you will not mistakenly purchase poor-quality solar panels. Of course, choosing a reliable quality manufacturer can also avoid this problem, so to save you the trouble of custom solar panels, just contact Findy Solar.
