What Are Flexible Solar Panels? (Complete Guide)
Flexible solar panels are transforming the way people access renewable energy, especially in remote locations or off-grid environments. Unlike traditional rigid solar panels, these lightweight alternatives can bend and contour to uneven surfaces, offering more versatile applications.
In this article, you will learn what flexible panels are, how they are used, and how to choose the right one for your needs to help you use this type of solar panel more wisely. Read on!
What Are Flexible Solar Panels?
Flexible solar panels are thin-film solar devices built to bend and adapt without cracking. Made from materials like cadmium telluride or amorphous silicon and protected by protective plastic layers, these panels offer a portable and easy-to-install alternative to rigid systems.
Additionally, as the flexible solar module technology continues to advance, these panels are becoming more efficient, reliable, and affordable. In fact, experts project that the global flexible solar panels market will reach $914 million by 2030.
Benefits of Flexible Solar Panels
Flexible solar panels offer unique advantages that make them ideal for a variety of uses.
Versatile Installation for Various Surfaces
One of the benefits of flexible solar panels is their ability to bend and fit onto irregular surfaces. Whether it's an RV roof, a boat, or even a backpack, it adjusts easily on an RV without the need for complex equipment. You can use industrial silicone adhesive, zippers, grommets, or Velcro straps instead of screws. The slim design makes it easier for users to carry on the go and set up.
Reliable in Harsh Weather Conditions
Durability is another reason why there are more and more flexible solar panels in Canada. Designed with resilient materials and protective layers, these solar panels can withstand wind, hail, snow, and UV exposure. In climates like Canada’s, where the weather can change suddenly, having panels that resist UV rays and moisture is especially beneficial.
Low Maintenance
Flexible solar panels have fewer mounting parts and no fragile glass layer, so they’re less likely to break or need repairs. Occasional surface cleaning is usually enough to keep them running efficiently for outdoor and mobile use.
How Are Flexible Solar Panels Used?
Flexible solar panels are commonly used in places where traditional rigid panels are impractical. Their smaller size and bendable design make them especially useful for outdoor activities such as camping and hiking or on RVs and boats in remote locations.
Here are a few typical use cases:
RVs: A flexible solar panel is ideal for vehicles with curved or limited roof space. Unlike rigid panels, these can be directly mounted in the small available space and are less affected by wind while driving.
Camping and Hiking: Its lightweight and portable panels are easy to carry and can charge small electronics like phones, GPS devices, or digital cameras, which don’t need a lot of energy.
How to Choose Flexible Solar Panels?
When choosing the right flexible solar panels, you should understand your needs and the features that matter most. Here are a few ways to help you get the one:
Check the Bending Angle
First, check their ability to contour to surfaces. Not all portable solar panels bend the same. Some can flex up to 30 degrees, while others allow a full 360-degree bend. Know your surface and select a panel with the bending capacity that fits it best.
Consider Installation Simplicity
Ease of installation can save solar costs. Portable panels offer this advantage over traditional solar panels. However, even though installation is claimed to be easy, you still need clear installation guidelines and instructions, as well as solar panel kits such as adhesives or Velcro to facilitate installation.
Evaluate Power Output
When choosing solar panels, it is important to consider the power output. Power output determines how much energy your panels can generate, which directly affects how many devices you can run simultaneously. For activities like camping, you may need higher wattage. However, higher wattage in flexible PV panels usually costs more.
Understand Panel Longevity
The longevity of a panel depends on its material. Panels made of glass and aluminum tend to last longer. In general, plastic panels degrade faster than those made of glass or aluminum, but high-grade plastics like ethylene tetrafluoroethylene (ETFE) offer better corrosion and rust resistance and perform well in damp environments. Choose a panel based on where and how often you’ll use it.
Factor in Size and Weight
Smaller, lightweight panels are easier to carry and store, especially for hikers or campers. While a panel weighing between four to eight pounds might be manageable for RV installations, it can become quite burdensome if you're planning to carry it during hiking trips. Portability is key for on-the-go use, so lighter options are often preferred for more mobile applications.
Check the Efficiency Rating
Efficiency shows how well a panel converts sunlight into usable energy. Most flexible panels offer around 15–18% efficiency, which is usually enough for smaller setups like RVs, boats, or portable charging. If you're after higher efficiency but still need something easy to carry, consider foldable panels. For example, the EcoFlow 110W Portable Solar Panel combines flexibility with up to 23% efficiency, making it a great choice for those who want strong output without giving up portability.

Conclusion
Whether you are off-grid adventuring or seeking backup power solutions, flexible solar panels offer a lightweight, portable, and durable option. Their bendable design, ease of installation, and resilience make them ideal for a range of applications, from camping to boating.
As Canada's demand for clean energy continues to rise, flexible panels are gaining popularity for their adaptability and performance. Make sure to evaluate your energy needs and environmental conditions before making a purchase.
FAQs
Are flexible solar panels worth it?
Yes, flexible solar panels are worth considering if you are looking for lightweight, adaptable, and easy-to-install energy options. They are especially practical for outdoor adventures, off-grid travel, and areas where mounting rigid panels is a challenge. Their compact, bendable design makes them an efficient choice for modern portable power solutions.
Do you need an air gap under flexible solar panels?
An air gap beneath flexible solar panels can aid cooling and potentially enhance performance. However, it's not a strict requirement. Most flexible solar panels are built to work efficiently even when installed directly on a flat surface, maintaining safety and performance under normal outdoor conditions without any complex mounting arrangements.
What is the life expectancy of flexible solar panels?
The average lifespan of flexible solar panels typically ranges from 5 to 15 years. This depends on various factors such as frequency of use, environmental exposure, and the overall build quality of the panel. With proper care and maintenance, high-quality models may last even longer and continue to perform efficiently.
