However, even after many advantages these solar panels offer, people often have questions like, What is the life of flexible solar panels? When to use them? Can they be installed anywhere? Can we cut them? Are they affordable? Are flexible solar panels worth it? Etc.
In this handy guide, we will tell you everything about flexible solar panels, from their uses, advantages, and disadvantages to different types. We will also provide answers to all your questions and provide some tips that will help you make informed decisions. Let’s start by learning what exactly are flexible solar panels.
Understanding Flexible Solar Panels
Before moving ahead, let’s try to understand what exactly flexible solar panels, how they are they in comparison to traditional rigid solar panels. Are they better or not?
What is a flexible solar panel?
The flexible solar panels contain materials that are flexible and can be bent in a flexible way without breaking. They are much thinner than rigid panels and very easy to carry and mount on uneven surfaces.
What is the difference between flexible and rigid solar panels?
The major difference between flexible and rigid solar panels is their ability to bend and adapt to different shapes. Flexible solar panels are light and hence easy to install on curved surfaces. However, rigid solar panels are heavy and can be installed on flat surfaces. To learn in detail, here is a table of differences:
| Feature | Flexible Solar Panels | Traditional Rigid Solar Panels |
| Flexibility | Bendable and adaptable to different surfaces | Rigid and designed only for flat surfaces |
| Weight | Lightweight and portable | Heavier and requires solid mounting |
| Installation | Easier to install on curved or irregular shapes. | Requires specific mounting structures to install. They can’t be curved or reshaped. |
| Efficiency | Generally less efficient (lower power output) | Higher efficiency (better power output) |
| Durability | Shorter lifespan and more prone to degradation | Longer lifespan and better durability |
| Applications | Ideal for boats, RVs, backpacks, and tents | Commonly used in homes, solar farms, and large installations |
| Cost | More expensive per watt | Generally more cost-effective per watt |
| Heat Dissipation | Less effective in heat dissipation | Better at dissipating heat |
When to use flexible solar panels?
Flexible solar panels can be used in places where there is limited space and weight-constrained situations, such as in a boat, a camper, or a backpack. They are also good-choice homes with irregular surfaces/roofs or rooftops of cars. They are great for temporary installations where there are size constraints for traditional solar panels. So, if are moving temporarily to a house or want portable solar systems, you must use flexible solar panels.
How Many Types of Flexible Solar Panels are There?
Now that we know what is it and when to use it, let’s learn about types of flexible solar panels. There are three types of flexible solar panels: silicon crystalline, thin-film, and organic with different technologies. Knowing about them will help you choose the right one for your energy needs.
- Silicon Crystalline Flexible Solar Panels: These panels are silicon-based and flex up to 30 degrees but are relatively light. They can be used in multiple applications with greater efficiency than their flexible counterparts.
- Thin-Film Flexible Solar Panels: These flexible solar panels have photovoltaic materials applied to surfaces such as aluminum sheets, or to fabrics. As such, they are highly portable, in that they can be rolled for storage. However, they are mostly very inefficient and less durable compared to silicon crystalline panels.
- Organic Flexible Solar Panels: This is a panel primarily made of organic material and graphene electrodes to facilitate performance. They are thin, flexible, and light; however, they are still under development, improving their efficiency and life.
Besides them, there are flexible solar panels called the Perovskite solar cells. They are a new generation of solar technology that has a special crystal structure that helps absorb sunlight with increased efficiency. They also weigh very light and may be made in flexible forms to use for flexible solar panels.
One reason why perovskite solar cells attract interest is their production cost, which is much lower than that of traditional solar cells. In fact, they have the possibility of converting more energy than the latter. Their elasticity makes it possible to be laminated on various materials.
