Shawllar’s Flexible Solar Panels to ‘Power the RV World’

[embedded content]

EDITOR’S NOTE: The following release is from Shawllar Energy, a tech-driven, clean energy solutions provider and an established industry leader focusing on smart energy and distributed smart photovoltaic systems with the world’s leading back contact MWT (metal wrap through) technology as the core. The parent company of Shawllar Energy is GoodWe Power Supply Technology Co. Ltd., which is a listed company of Shanghai SE, and has been focused on solar energy inverters and energy storage industry for more than 10 years.

Flexible Modules, RV’s Choice of Future

Flexible photovoltaic (PV) modules have a relatively short history compared to traditional rigid solar panels. The first flexible solar cells were developed in the 1960s by the United States for use in space applications. However, the first commercially available flexible solar panels were not introduced until the 1990s.

The initial flexible solar panels were made using amorphous silicon, which is a thin-film PV technology that can be deposited on a flexible substrate. However, these early amorphous silicon modules had low efficiency rate and were not very durable.

In the early 2000s, new materials and manufacturing processes were developed that allowed for the production of more efficient and durable flexible solar panels. Metal wrap-through (MWT) and interdigitated back contact (IBC) are two different solar cell technologies that aim to improve the efficiency and performance of photovoltaic cells.

Today, flexible solar panels are used in a variety of applications, including on boats, RVs, and other mobile applications, as well as for building-integrated solar installations where traditional rigid panels are not feasible. This article will introduce why we believe flexible modules will be the future for RV market and why SHAWLLAR should be your first choice!

The PV module products for RV market has gone through the transition from rigid panels to flexible panels then back to rigid for a while now. The design trend of the recreational vehicles is to develop towards light weight and low center of gravity due to safety concerns and the growing need for more and more home appliances in the vehicles.

In the early stage of the development of thin-film modules, this type of product accounted for about 30% of the market share in the 1980s due to its low-cost advantage; however, the lack of ability to break through the efficiency bottleneck, combined with the significant reduction in the price of crystalline silicon, led to the gradually decreased market share of thin-film modules. Mediocre efficiency level and higher production cost became the main factors for the elimination of thin-film modules.

With the continuous breakthrough and innovation iteration of flexible module technology, MWT , as the new generation of back contact technology after IBC, is a more suitable technical solution for producing flexible modules. The full name of MWT technology – Metal Wrap Through is a technical route to obtain high-efficiency, high-reliability, low-cost, and eco-friendly PV modules by preparing both positive and negative electrodes on the back side of the cell.

As a major photovoltaic manufacturer, Shawllar Energy, equipped with the latest European 4.0 fully automated industrial production line, applies the core MWT technology to the fluorine back sheet materials, only to produce the advanced and reliable flexible solar panels. The MWT technology applied in the Shawllar RV photovoltaic system has been the only technology that participating in the VIPV ROUND-ROBIN TEST (vehicle integrated photovoltaic cycle experiment) of Toyota Motor over the past 5 years.

 The inevitable choice of light weight trend of RV

Compared with flexible solar panels, rigid modules are obviously heavier, weighing about 70Kg per 1000W. And due to the additional height of rails, it will lead to potential increased wind resistance and less stable center of gravity, especially when driving through corners and mountain roads.

The flexible module is lighter in weight and thinner in thickness. With only 14Kg per 1000W, it can be easily installed close to the roof, which greatly reduces the impact on the center of gravity without bringing additional wind resistance. The flexible module can also be installed on different kinds of curved rooftop, which is suitable for a variety of RV models with increased installation capacity.

From the aspects of the above comparison, we can see that the advantages of flexible modules are very obvious. Flexible modules perfectly meet the future RV design concept, but only qualified flexible modules are the choice of the future.

Professional manufacturing, comfortable experience

So what kind of module is considered a qualified flexible module?

A good photovoltaic system should meet the following 6 requirements:

1. Qualified raw material and product quality
2. Use fluorine-contained back sheet
3. Being strictly tested and obtain one of the three certifications: CQC, TüV and CDC
4. Adopt light weight and ultra-thin module features
5. Higher efficiency with smaller area for the same amount of power
6. Standardized production line with advanced technology and guaranteed worry-free after-sale warranty

In the continuous market exploration and achievements, SHAWLLAR ENERGY has innovated and upgraded flexible technology to meet market demand. Today’s SHAWLLAR flexible solar panels have dispelled the key concerns of most RV riders, met their electricity needs, and gained extensive praise from customers and RVers at home and abroad.

Shawllar Energy’s flexible solar panels are one of the few in China that have passed TüV test in Germany. The product strictly adopts fluorine back sheet produced by the top two listed companies in PV industry, which has excellent weather resistance, UV resistance, high temperature resistance, high humidity resistance, salt spray resistance and other properties, and has long-term outdoor environment damage resistance. The junction box is also made of IP68 waterproof grade material, so there is no problem at all when immersed in water.

High quality and innovation has always been the technical pursuit of Shawllar Energy, Shawllar’s flexible photovoltaic products have successfully obtained TüV, CE, FCC, RoHS and UKCA certifications. High quality and pioneering technology has long been recognized by the industry, Shawllar Energy has proved its excellent quality to the world!

Shawllar Energy not only has strict control over product quality, but also has more extreme pursuit on our service system. Shawllar Energy ‘s flexible solar panels offer a 5-year product warranty and a 12-year linear power warranty, which guarantees that the product will still hold more than 80% of power generation efficiency after 12 years of sale.

Focused on R&D of outdoor power supply system, Shawllar Energy is on the mission to offer the best vanlife experience, and power the RV world.
