Substituting for the rigid glass and aluminum frame of regular panels, a flexible material houses the photovoltaic cells inside flexible solar panels. The versatile and innovative design of flexible solar panels makes them easy to fit on irregular or curved surfaces.

Available in a wide range of shapes and sizes, flexible solar panels are classified into the following types.

1. Thin-film solar panel.

Because thin-film flexible solar panels are the least powerful and least efficient compared to monocrystalline and polycrystalline solar panels, they’re the most affordable and make sense for light-duty power needs. These solar panels are thinly layered with photovoltaic materials, such as amorphous silicon, CIGS (copper indium-gallium-selenide), and CdTe (cadmium telluride). Thin-film solar panels don’t contain silicon wafers. Thus, they are less durable and have a shorter lifespan than their crystalline silicon solar cell counterparts.

2. Polycrystalline solar panel.

Polycrystalline solar panels cost a bit more than thin-film panels but are cheaper than monocrystalline solar panels. They produce a good amount of power at their price point among flexible panel types, although they're not the most efficient. Unlike mono panels, polycrystalline panels are made with fragments of silicon cells. This creates imperfections that end up reducing the efficiency of these panels.

3. Monocrystalline solar panel.

Monocrystalline solar panels are the most energy efficient. Made from quality material, monocrystalline solar panels are durable and generate the most electricity out of all photovoltaic panels on our list. Silicon wafers are the key component of monocrystalline panels, allowing maximum sunlight absorption. As you might expect, these panels are the most expensive.

The table below lists the advantages and disadvantages of thin-film flexible solar panels and crystalline silicon flexible panels.

Flexible Solar Panel Pros and Cons
Advantages Disadvantages
Thin-Film Solar Panel Lightweight You will need more solar panels to generate a sufficient amount of electricity
Easy to bend Not so energy-efficient
It can be attached to all kinds of surfaces
Crystalline Silicon Solar Panel (Mono- and Polyflexible) Longer lifespan Expensive
More energy efficiency Less flexible
Higher energy conversion

Things to Consider Before Buying Flexible Solar Panels

Consider the following factors when comparison shopping for the right flexible solar panel for your needs.


Keep in mind that power is the main reason you are purchasing flexible solar panels. While a 100-watt flexible solar panel can power a small workstation or boat for three to four hours, high-wattage flexible solar panels would be the better choice for RVs. If you only want to use the solar panel to charge your smartphone, a 20-watt panel would be enough. Remember, the higher the wattage, the higher the price.


Wattage significantly influences the cost of flexible solar panels. Good quality, 100-watt monocrystalline flexible solar panels can cost you $120 to $125. However, the price of a high-capacity solar panel can range from $275 to $600. Note that these are the prices of only one flexible solar panel, and you might need multiple panels to power your RV or campsite.


Because of their shorter lifespan, flexible solar panels have limited warranties. High-quality flexible solar panels are backed by a five-year warranty, which includes workmanship, repairs, power production guarantee, and much more. Contrast this with the conventional solar panels that power homes—they often come with 20- or 25-year warranties.


While most flexible photovoltaic panel kits already come with inverters, lithium batteries, power outlets, and charge controllers, some manufacturers sell the panels solo. Therefore, it’s important to consider the included components to ensure that you get the best flexible solar panels for your budget.


You might need to carry the flexible solar panels in your backpack while you hike. Therefore, make sure that they weigh no more than 5 pounds. The weight of the flexible solar panels increases as the wattage increases. A 300-watt panel weighs 8 pounds, for example, while a 100-watt panel weighs 4 pounds.


If you are looking for long-lasting flexible solar panels, choose the ones manufactured of durable polymer substances, as they can last up to 10 years. The most common polymers used for the production of flexible solar panels include:

  • ETFE (ethylene tetrafluoroethylene): Longer life, improved sunlight absorption, and protection from corrosion
  • PET (polyethylene terephthalate): Dust-resistant and lightweight

Tip: You can read the owner’s manual to learn about the durability of flexible solar panels.


The majority of flexible solar panels have an efficiency rating of 10% to 15%. However, premium-quality flexible solar panels can provide energy efficiency as high as 25%.
