Feb 13, '23

Solar panel technology is constantly evolving. New products like flexible solar panels are bringing more ways for people to harness the power of the sun.

These products are durable yet foldable and portable so that you can use them however you want. Flexible solar panels are also very lightweight and can be used off the grid.

That being said, we get a ton of questions from our customers about the different types of flexible solar panels that are available and what differentiates them from one another.

That’s why we’ve created this guide. It features six of the best flexible solar panels for 2023. It’s perfect for RVers, campers, boating enthusiasts, and anyone who loves the outdoors.

So, without further delay, let’s get into it.

What is a Flexible Solar Panel?

Flexible solar panels can be easily bent, folded, or wrapped around different objects. This makes them a great fit for irregular roofs, such as RVs and boats. Many people also use them in off-the-grid applications.

These lightweight panels are made of flexible photovoltaic cells that convert solar energy into electricity just like standard solar panels. However, it is important to note that they are slightly less efficient.

Flexible solar panels are made with a technology called thin-film photovoltaics, which is translucent. That means you can also mount these panels on glass or use them directly as windows.

Types of Flexible Solar Panels

There are several different kinds of flexible solar panels available to choose from. Each offers its own pros and cons. We’ll look at some of the most common options in this section.

  1. Amorphous Silicon (a-Si) Flexible Solar Panels: These panels are made using a thin film of amorphous silicon, which is a non-crystalline silicon. They’re known for their low cost and versatility, which makes them a popular choice for various applications.
  1. CIGS Flexible Solar Panels:CIGS (Copper Indium Gallium Selenide) flexible solar panels are made using a thin film of CIGS photovoltaic material deposited onto a flexible substrate. They’re known for their high efficiency and flexibility, making them a popular choice in portable devices and wearable technology.BougeRV's CIGS solar panels are the best on the market today. We’ll list some of them below for your reference.
  1. Graphene Flexible Solar Panels:Graphene flexible solar panels are made using a thin film of graphene, a material known for its excellent conductivity and strength. They’re still in the development stage but have the potential to be highly efficient and long-lasting.
  1. Monocrystalline Flexible Solar Panels:These panels are made using a thin film of monocrystalline silicon, a highly pure form of silicon. They’re known for their high efficiency and durability. But they’re also more expensive than other flexible solar panels.
  1. Polycrystalline Flexible Solar Panels: These panels are made using a thin film of polycrystalline silicon, a less pure form of silicon. They’re known for their lower cost and good efficiency, making them a popular choice for various applications.

What to Look For in Flexible Solar Panels

Flexible solar panels are a relatively new technology, which means this may be your first purchase of them. If so, here are the factors to pay attention to while shopping.

Efficiency: Flexible solar panels generally have lower efficiency than traditional, rigid solar panels. However, some flexible panels have been developed with efficiencies of up to 20%, which is solid. The efficiency rate can vary depending on the technology used to create the panels.

Wattage: Flexible solar panels come in a range of wattages, and the size of the panel you need will depend on your power requirements. Higher-wattage panels produce more electricity than lower-wattage panels, but they will also take up more space.

Durability: Flexible solar panels are designed to be more durable and resistant to damage than traditional panels. If you plan on using these outdoors, you’ll want panels that are designed to withstand conditions like rain, wind, and extreme temperatures.

Flexibility: Make sure to check how flexible the panels are as well. Some might not be flexible enough to fit the shape or curvature of your intended installation surface.

Brand and Warranty: Research brands and look for panels from reputable manufacturers that offer long-term warranties. Make sure to read and understand the terms of the warranty as well, as it can vary from one manufacturer to another.

Size and Weight: Flexible solar panels are generally smaller and lighter than traditional, rigid solar panels. This makes them easier to transport and install. However, it’s important to note that this does not mean the panels produce less electricity.

Cost: Flexible solar panels can be more expensive than traditional, rigid solar panels. That means it's important to consider the cost – both upfront and over the lifetime of the panels – to determine which option is best for your needs.

One last thing to note is that flexible solar panels are not as efficient as traditional panels. They’re also not suitable for all applications. If you’re unsure about whether this kind of panel is right for you, don’t hesitate to reach out to the BougeRV team for some guidance.

This makes it less susceptible to external influences, which makes it a great option for outdoor enthusiasts who walk away from their RV or campsite for large portions of the day.

What do users like? Our user Smith said:

“Make a few brief comments. I am a loyal fan of CIGS. I once bought 100W CIGS. To my surprise, the product workmanship is really excellent! So I want to buy 200W CIGS, but the customer service told me that 200W CIGS solar panel with adhesive is very popular, and the next batch of goods will not be sold until the middle of December.

But recently, I found that bougerv has newly launched 200w cigs with holes. I did not hesitate to place three, and I'm afraid there is no stock. I ordered the goods the day before yesterday, and it is here today. The delivery is fast. Bougerv's product packaging is perfect. After I opened it, there was no damage.”

BougeRV also has several 100W flexible solar panels available. There are currently four models that we’d like to draw your attention toward.

“I bought two CIGS 100W Flexible Solar Panel to go with my 40a mppt Rover charger and a 50ah lithium ion phosphate, all from BougeRV, for my homemade camper. The panels are sturdy, well designed, and affordable. They come ready to go with MC4 connectors.

Even when the weather isn't idea (cloudy rainy days), I'm still getting more than enough power to charge my 50ah battery. The mppt charge controller is very efficient and able to utilize the panels efficiently. So far everything is working great.”


Are flexible solar panels any good?

Flexible solar panels, also known as "thin film" solar panels, can be a good option for certain applications. They are lightweight, durable, and can be bent or folded to fit onto curved surfaces, making them well-suited for use on boats, RVs, and other vehicles. They are also useful in situations where a traditional rigid panel would be too heavy or difficult to install.

However, flexible solar panels generally have lower power output and efficiency compared to traditional rigid panels. They also tend to degrade faster in extreme temperatures and are often more expensive in terms of cost per watt.

Can you walk on flexible solar panels?

Flexible solar panels are designed to be more durable than traditional rigid solar panels, but they are not meant to be walked on. Walking on the panels can cause damage to the cells and the encapsulation material, reducing the panels' performance and lifespan.

In general, you shouldn’t walk on solar panels because it can cause both physical damage and performance reduction. If you need to access the roof area where the flexible panels are installed, you should use a walkway specifically designed for that purpose. And make sure to have the proper equipment and safety measures to protect both the panels and the person.

Can flexible solar panels get wet?

Flexible solar panels can typically withstand exposure to rain and other forms of precipitation. But prolonged exposure to water can cause damage to the cells and the encapsulation material, reducing the panels' performance and lifespan.

Most solar panels are sealed and water-resistant but not necessarily waterproof. They are designed to keep water out but may not be able to handle standing water or heavy rain.

Manufacturers will typically specify the level of water resistance in the product's specifications, including the level of ingress protection (IP) rating. For example, an IP65 rating means that the product is dust tight and can withstand water projected by a nozzle.
