Sungold Best Flexible Mono Solar Panels LE-M2-270W
SUNGOLD LE-M2-270W products are mono solar panels, only 4mm thickness, functional, waterproof, lightweight, and durable. Its surface uses ETFE material, and the biggest feature is ultra-light, 50% lighter than the glass solar panel with the same power.
Equipped (two 20SQ045 diode, 900mm/4mm² single-core cable+MC4 connector), the LE series mono solar panels are convenient to install and can provide electricity for RVs, sea ships, tents, etc. If you want to get a strong motivation without sacrificing the fuel economy, this will be a good choice.
LE-M2-270W mono solar panels have a solid ETFE surface, which is made of 182 (10 gate bus) solar cells. It’s really suitable for a long-term outdoor application, supply free electricity for 12V/24V solar system, like RV, Caravan, camper van, boats, or solar lighting system, off-grid solar system or back-up solar systems.
The flexible mono solar panels can also be used for those are not sensitive to the input voltage/current application(such as electric motors or pumps) and various on-grid systems.
The surface of this 270W flexible etfe solar panel is designed with ETFE material, which has a longer lifespan compared to standard semi-flexible solar panels. So these special semi-flexible mono crystalline solar panels are very wear-resistant and less prone to cracking, delamination and corrosion. The lightly textured coating of solar photovoltaic panels creates an anti-reflective surface that allows the panel to absorb more light, increasing efficiency.
The solar photovoltaic panels also feature an innovative 10-busbar solar cell that is more efficient than the 3, 4, or 5-busbar solar cells used by most other solar panels and is able to extract more energy from the same surface area. This results in a smaller overall solar panel, ideal for applications where space is limited. These mono crystalline solar panels are also the best choice for applications in warm climates as they work well even in high ambient temperatures.
The cable has a waterproof MC4 connector that can be used to easily connect to your existing system for connecting multiple panels together or connecting 4mm2 extension cables. At the same time, it is also equipped with a bypass diode to reduce the hot plate effect.
The LE-M2-270W best flexible marine solar panels has so durable ETFE surface and is made of monocrystalline 182 (10 grid busbar) solar cells. It is one of the innovative products of lightweight solar panel 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
The product is installed on the yacht, and the surface may block the sun when it is not in 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.
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 focuses on manufacturing of solar panels and keeps innovating processes. The products use specially developed patented materials and the latest solar cell technology to achieve higher conversion efficiency.

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 mono solar panels, 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 series 270W surface materials. What is the reason?
Answer: The product is installed on the yacht, and the surface may block the sun when it is not in 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
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 focuses on manufacturing of solar panels and keeps innovating processes. The products use specially developed patented materials and the latest solar cell technology to achieve higher conversion efficiency.
