How to distinguish the quality of small solar panels? 6 Tips

Solar panels, also known as solar chips, are Semiconductor Optoelectronics wafers that use solar light to generate electricity. It acts as an important role in every field of new energy. It is widely used, as long as it is used in photovoltaic products.  The quality of the small solar panels components are directly related to the energy efficiency of the products used.

Nowadays, there are many solar panel manufacturers yet the poor-quality products are also mixed in. Indeed, it is not easy to select a good quality solar panel.

DEL ILLUMINATION will tell you how to distinguish the quality of them.

1. Check the front side

First and the foremost, we must carefully inspect the surface of tempered glass, which is also the part where some solar panel manufacturers missed to observe. If the silica gel is accidently dropped on the surface of the tempered glass, it must be removed in time. If it is not removed, the power generation efficiency of the panel will be affected.

2. Check the cell

Many unqualified manufacturers will assemble with the damaged cell to save the cost. The seemly complete cell is in fact with great risk. It may be safe in the initial stage, but the spliced cell will easily break under in the long-term and influence the usage of entire panel. When the temperature is too high, it will cause fire and threatens the life safety of pedestrians.

3. Small solar panels: Check the backside

The back of the solar panel should be marked with technical parameters, such as: open circuit voltage, short circuit current and working voltage. Secondly, check the loading pressure on the back of the solar panel. If bubbles and wrinkles appears after the loading, then such solar panels are classified us unqualified.

4. Check the junction box

The junction box is a connector of the solar cell module, and the main function of the solar photovoltaic junction box is to derive the electrical energy produced by the solar cell module through the cable.  Whether the junction box is firm or not is also related to the efficiency of the solar panel. The cover of the junction box should be firmly and closely attached to the junction box, and the lock of the outlet cable lock should be able to rotate and tighten freely.

5. Brand reputation

When evaluating the quality of your small solar panels, it is important to consider the reputation of the brand that produces it. Reputable small solar panels brands build their reputation over time by producing high-quality products and providing excellent customer service.

Small solar panel brands that have a good reputation invest heavily in research and development to create durable, efficient, and reliable products that can withstand various environmental conditions. To assess brand reputation, it is essential to look beyond marketing materials and seek feedback from other customers through online reviews or recommendations from friends and industry professionals.

6. Warranty

A warranty is a key factor to consider when evaluating the quality of small solar panels. It is essentially a promise from the manufacturer that their product will perform as expected, and that they will provide support or replacement in case of any issues.

When it comes to small solar panels, warranties typically cover two main aspects: workmanship and performance. Workmanship warranties typically cover defects that arise during manufacturing, such as faulty wiring or damaged components. Performance warranties, on the other hand, guarantee that the panel will generate a minimum amount of power over a certain period of time.

It is important to carefully review the warranty terms and conditions before purchasing your small solar panels. This will help you understand what is covered, how long the warranty lasts, and what steps you need to take if you need to make a claim.

Conclusion

Be sure to pay attention to the above 6 main points when purchasing solar panels. In addition, you should select according to your needs so that the quality of the chosen small solar panels can be more assure.
