Sungold High Efficient Solar Panels LE-M2-120W

Sungold High Efficient Solar Panels LE-M2-120W

SUNGOLD LE-M2-120W is a lightweight solar panel and its thickness is only 4mm. This LE series 120W high efficient solar panels are powerful, waterproof, lightweight, and durable. Its surface uses ETFE material, the biggest feature is ultra-light, 50% lighter than the same wattage rigid solar panel. The LE series 120 watt monocrystalline solar panel is easy to install and can provide electricity for RVs, sea ships, tents, etc. No bracket, energy saving, and environmental protection. If you want to get a strong motivation without sacrificing the fuel economy, this will be a good choice.

Description

The LE series high efficient solar panels have 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. It breaks a traditional view that ordinary cells can only be used as rigid solar pv modules.

The high efficient solar panels are suitable for using in long-time outdoor and can provide free power for 12V/24V solar system and a variety of applications such as RVs, caravans, campers, boats, solar lighting systems, off-grid and backup solar panel systems. The solar panel can also provide direct power for applications that are not sensitive to input voltage/current variations (such as motors or pumps) and various off-grid applications.

 

Product Features

LE-M2-100W Flexible Solar panel

Glass fiber backpanel and surface ETFE coating

Glass fiber backpanel and surface ETFE coating

The surface of this 120 watt 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.

High -quality 10 bus solar cell

The 120 watt 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.

waterproof MC4 connector

Easy To Use

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.

FAQ

 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.

1.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 high efficient solar panels 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 120W surface materials. What is the reason?

Answer:The high efficient solar panels 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 solar panel 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 light 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 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.
