The best flexible solar panels work by providing low-cost, off-grid power on-the-go, making it ideal for boats, RVs, cabins, and other outdoor locations and activities like camping and hiking.

Sometimes, when homes cannot use the traditional, rigid solar panels due to uneven roof or other reasons, flexible solar panels serve as a pretty good alternative.

In the solar industry, flexible solar panels are called "thin film panels." This is because they are made from layers of one or more photovoltaic (PV) material on top of glass, metal or plastic. These layers end up over 300 times smaller than the standard silicon-based solar panels.

The design of flexible solar panels makes them a lot more lightweight, portable and flexible, while keeping the durability and energy-efficiency of traditional silicon panels.

What better way to understand the capabilities of flexible solar panels than to check out the current models offered in the market today. We've handpicked several interesting models that may fit your requirements:

1. SunPower 100 Watt Flexible Monocrystalline High Efficiency Solar Panel

SunPower 110 Watt Flexible Solar Panel

Factors To Consider When Buying the Best Flexible Solar Panels

The prices of flexible solar panels only include the solar panel kits. For this to work, you'll need a solar controller, deep cycle battery, battery connectors, and other optional accessories like extended solar panel wires. 

Like other types of solar panels, these super-thin, flexible solar panels have their own pros and cons. As such, you have to weigh these considerations before buying one of the best flexible solar panels we've compiled above:

  • Power - When choosing flexible solar panels, check those with high power outage, since the higher watts produced means you'll need fewer panels. Note that the power of flexible solar panels would also depend on application: Is it to power a camper at night, or simply to recharge gadgets? Flexible solar panels usually go around 100 to 400 watts.
  • Efficiency - The efficiency of flexible solar panels refers to the amount of sunlight the unit could convert into usable electrical energy. Generally, it is best to find a model with energy efficiency of 11% to 20%.
  • Semiconductors - One of the biggest differences between flexible solar panels and the thicker traditional ones is the production process. With flexible solar panels, a mix of semiconductors is sprayed on to an underlying layer. The three most common semiconductors are 1: Amorphous silicon (a-Si), 2: Cadmium telluride (CdTe), and 3: Copper, Indium, Gallium Deselenide (CIGS). You'll determine which semiconductors are used on a particular flexible solar panel once you see the suffix attached to the model name.
  • a-Si is the oldest and most commonly used, but it is notorious for aging quickly after direct sun exposure
  • CIGS is newer and uses Gallium to slow down the aging of solar cells
  • Flexibility - This refers to the maximum angling the panel could curve without breaking. Generally, 30 degrees is more than enough flex range for most applications.
  • Warranty - Even the best flexible solar panels do not last as long as rigid ones. As such, warranties usually go for 1 to 2 years. However, there are gems that may offer 5-year warranties, so watch out for these brands.

Other considerations like size and weight are also important, especially since every project is different and has varying requirements.

Wrap Up: Which is the Best Flexible Solar Panels for Me?

Note that this list of best flexible solar panels just touches the tip of an iceberg - there are dozens of other models that would be perfect. However, we stuck to 100-watt models to cater to beginners looking to give flexible solar panels a shot and these 7 could definitely deliver.

For those on a budget, ultra lightweight Richsolar 100-watt 12-volt flexible solar panels is one of the most inexpensive, yet durable and efficient flexible solar panels around. But if you're looking for a kit that could be used in virtually any possible application, check out the high-efficiency GIARIDE 100-Watt Flexible Solar Panels.

Our top pick is Renogy's RNG-100DB-H 100-Watt 12-Volt Extremely Flexible Monocrystalline Solar Panel, since it is relatively affordable, powerful and has the most features out of all models we handpicked. Plus, this kit offers the longest warranty.

Make sure to weigh the considerations listed above, and if you can't get past the technical stuff, go with the one with the best warranty, since it is often a good indicator that the company is confident about their product's durability.
