1.What are the possible reasons for the product without voltage and current output?
Answer: If there is no voltage and current output of the LE series 100W Solar Panel products, the main reason is that the copper zone of between solar cells appears to be disconnected in multiple places, causing no voltage and current data.
The copper band connected between the solar cells is welded with a stamping copper tape structure to enhance the firmness and stress area of the copper band.
2.There are bubbles for LE 100W Solar Panel surface materials. What is the reason?
Answer: The 100W Solar Panel is installed on the yacht, and the surface may block the sun when in no use, causing the hot spot effect. The local surface temperature rises, which affects the adhesion of the product surface material and EVA.
When the ambient temperature decreases, the shrinkage causes local whitening. Therefore, avoid the product being blocked and placed with hard objects to cause damage to the cells during use.
3.What is the reason for no voltage output when we install the lightweight board to the RV?
Answer: There will be no voltage output installed on the RV in the market. It can be determined whether the copper tape is disconnected after the product is vibrated on the top of the RV.
If it is disconnected, it will be affected. The glass fiber material process we used in Sungold can prevent this problem occurs.
4. Is the diode of the LE series lightweight solar panels junction box easy to burn out?
Answer: The diode of the junction box will burn out due to excessive external reverse current. We generally standardize the protective measures of the product during use in the product manual.
5.Is the junction box used in the lightweight solar panel waterproof?
Answer: We use the glue-filled junction box to install the product, so it has excellent waterproof performance and can resist the impact of the external environment.
6.Why can you trust sungold solar’s solar panel products?
Answer:Sungold solar is a one of the leading chinese solar panel suppliers. Sungold solar focuses on manufacturing solar panels and keeps innovating processes. The products use specially developed patented materials and the latest solar cell technology to achieve higher conversion efficiency.
