Description

LE-M2-220W flex solar panels have a solid ETFE surface, which is made of single crystal 182 (10 grid bus) solar cells. This 220W flex solar panels are very suitable for long-term outdoor use.

It provides free electricity for a 12V solar system or 24V system, supplying various applications, such as RVs, cars, camping cars, and ships, or for solar lighting systems, and spare solar power generation system.

This flex solar panels can also provide direct power supplies for applications that are not sensitive to input voltage/current changes (such as electric motors or pumps) and various grid-connected applications.

Product Features

LE-M2-220W Flexible Solar panel

Glass fiber back panel and surface ETFE coating

ETFE coating

The surface of this 220W semi-flexible mono solar panel is designed with ETFE material, which has a longer lifespan compared to standard semi-flexible solar panels. So these best photovoltaic panels are very wear-resistant and less prone to cracking, delamination and corrosion. The semi-flexible solar panel’s lightly textured coating creates an anti-reflective surface that allows the panel to absorb more light, increasing efficiency.

High -quality 10 bus solar cell

The 22W best semi flexible solar panel also features 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. It makes a smaller overall solar panel, ideal for applications where space is limited. These solar cells are also the best choice for applications in warm climates as they work well even in high ambient temperatures.

High -quality 10 bus solar cell
Easy to use and flexible

Easy to use

The cable comes with a waterproof MC4 connector for easy connection to your existing system, for connecting multiple panels together or attaching a 4mm2 extension cable. Also paired with bypass diodes to reduce hot plate effects. Polymer technology allows flexible solar modules to be mounted directly on curved surfaces without additional structural support.

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

The product is installed on the yacht.The panel is not be used on the shore, there are hidden dangers to cover the sun on the surface and cause heat spot effect. when local surface temperature rises, which affect the bond of product surface materials and EVA. Conversely, when the temperature drops, the solar panel shrinks, causing localized whitening. Therefore, when using, avoid the product be blocked and no placed with hard objects to damage cells.

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.

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 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 220W surface materials. What is the reason?

Answer: The marine solar 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 battery 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 was established in 2008, is a one of the leading chinese solar panel manufacturing 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.
