Sungold Flexible Solar Panel LE-M2-180W
No racking required, energy efficient, and environmentally friendly. If you want to get powerful power without sacrificing fuel and economics, this will be a good choice.
SUNGOLD LE-M2-180W is a lightweight solar panel. The surface of the solar panel is made of ETFE material, which is anti-corrosive and weather resistant. 180W Flexible solar panels are used for RVs, they are easy to install and can provide power for yachts, campers, tents, etc.
The surface of this 180W solar panels is made of strong ETFE material, which has a longer lifespan compared to standard semi-flexible solar panels. So these special lightweight solar panels are very wear-resistant and less prone to cracking, delamination and corrosion. The panel’s slightly textured coating creates an anti-reflective surface that allows the panel to absorb more light, increasing efficiency. The ETFE material improves the weather resistance of the solar pv modules as a whole.
The 180W monocrystalline solar panel also uses an innovative 10-bus solar cell, which is more efficient than the 3, 4, or 5-bus solar cells used by most other solar panels, which is more than 0.3%-1.5%. This has led to smaller solar panels as a whole, which are very suitable for applications with limited space. These solar cells are also the best choice for application in a warm climate, because they can work normally even at high environmental temperatures.
The cable has a waterproof MC4 connector, which can be used to easily connect to your existing system and use it to connect multiple solar pv modules or connect 4mm2 to extend the cable. At the same time, it is also paired with a bypass diode to reduce the hot spot effect.
The LE-180W mono pv module has a very durable ETFE surface and is made of monocrystalline 182 (10 grid busbar) solar cells. It is one of the innovative products of lightweight solar panels using monocrystalline cells .

If there is no voltage and current output of the LE series 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.
When the solar panel is installed on the yacht, during no use, due to the sunshade, a hot spot effect will occur. The local surface temperature of the solar panel increases, which affects the adhesion of the surface material and EVA. When the temperature drops, the local surface will turn white , the bubbles disappear. Therefore, when using it, it is best to avoid using it in covered occasions.
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.
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.
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.
Sungold solar is a one of the leading chinese solar panel manufacturers.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.

What are the possible reasons for the product without voltage and current output?
If there is no voltage and current output of the LE series products, the main reason is that the copper zone between solar cells appears disconnected in multiple places, causing no voltage and present 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.
There are bubbles for LE 180W surface materials. What is the reason?
When the 180W solar panel is installed on the yacht, during no use, due to the sunshade, a hot spot effect will occur. The solar panel’s local surface temperature increases, affecting the adhesion of the surface material and EVA. The local surface will turn white when the temperature drops and the bubbles disappear. Therefore, when using it, it is best to avoid using it on covered occasions.
What is the reason for the no voltage output when we install the lightweight board to the RV？
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.
Is the diode of the lightweight solar panel’s junction box easy to burn out?
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.
Is the junction box used in the lightweight solar panel waterproof?
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.
