Flexible or Rigid, that’s a question. Flexible solar panels Vs rigid solar panels have always been a challenge to consider when choosing solar panels. This article will analyze the advantages and disadvantages of flexible solar panels and rigid solar panels to help you choose the best solar panel for your solar project.
What Is the Difference Between Flexible Solar Panels and Rigid?
The main differences between flexible solar panels and rigid solar panels are their appearance, construction, and use scenarios.
Flexible solar panels generally use thin-film solar cell technology and can change shape by curling and folding. They are lightweight, thin, and flexible, and are suitable for use on surfaces that need to be curved or curved, such as sailboats, campers, tents, etc. However, compared to rigid solar panels, flexible solar panels generally have a lower conversion efficiency and are less durable and stable, and are easily damaged by environmental influences.
Rigid solar panels generally use silicon crystalline solar cell technology, which generally does not break due to bending due to its sturdy structure, and also has a relatively high conversion efficiency and can work under low light conditions. Rigid solar panels are suitable for installation on fixed planes, such as roofs and solar power stations. However, the disadvantages are their large size, heavy weight, and high cost.
Pros of Flexible Solar Panels Vs Rigid
What Are the Pros of Rigid Solar Panels? Flexible solar panels usually use thin-film solar cell technology, which can adapt to various curved or irregular surface shapes, are lightweight and flexible, and are suitable for outdoor travel, camping, and other scenarios. Rigid solar panels, on the other hand, usually use silicon crystalline solar cell technology, which is highly efficient in conversion, durable, easy to install, and can be used for a long time under various harsh weather conditions. Below we will detail the respective advantages of flexible solar panels and rigid solar panels.
|Flexible Solar Panels
|Rigid Solar Panels
|High conversion efficiency
|Easy to carry
|Easy to install
Pros of flexible solar panels:
- Adaptable: Flexible solar panel adopts thin film solar cell technology, which is lightweight and flexible and can adapt to various curved or irregular surface shapes, such as ships, tents, luggage, etc.
- Easy to carry: Flexible solar panels are light and thin, easy to carry and install, and suitable for outdoor travel, camping, and other scenarios.
- Flexible installation: Flexible solar panels can change their shape by curling and folding, so they are relatively flexible in installation and suitable for various scenarios with irregular surfaces.
- High safety: Flexible solar panels use flexible organic materials, unlike rigid solar panels that are easily broken, making them safer to use.
Pros of rigid solar panels:
- High conversion efficiency: Rigid solar panels usually use silicon crystalline solar cell technology, which has high conversion efficiency and can work under low light conditions.
- High durability: Rigid solar panels have a strong shell that can withstand various harsh weather conditions and long-term use, and have a long service life.
- Easy to install: Rigid solar panels have a regular shape and are generally easy to install as they only need to be fixed on a stand.
- Good stability: The silicon crystalline solar cell technology used in rigid solar panels is relatively mature and has long-term stability and can output energy stably.
Cons of Flexible Solar Panels and Rigid

|Higher temperature impact
Cons of flexible solar panels:
- Insufficient durability: Flexible solar panels are usually made of organic materials, which have relatively low durability and anti-aging ability, and are prone to light attenuation after prolonged use, reducing the performance of the panels.
- Easily damaged: Since flexible solar panels are relatively thin, they are susceptible to physical damage, such as scratches and tears, and these damages can cause the performance of the panels to decline.
- Higher price: The manufacturing process of flexible solar panels is relatively complex, so the price is higher.
Cons of Rigid Solar Panels:
What Are the Cons of Rigid Solar Panels?
- Higher weight: Compared to flexible solar panels, rigid solar panels are heavier and less suitable for scenarios where they need to be carried.
- Installation limitations: Because of the regular shape of rigid solar panels, they cannot adapt to the shape of various curved or irregular surfaces and require the use of fixed brackets for installation, which is relatively more complicated.
- More brittle: Rigid solar panels use silicon crystalline solar cell technology, and although they have strong durability, their shells are relatively fragile and easily damaged by impacts, drops, and other physical damage.
- Higher temperature impact: In high-temperature environments, the conversion efficiency of rigid solar panels is reduced, so heat dissipation is required.
Flexible vs. rigid solar panels: Which is better?
With the popularity of solar energy, more and more people need flexible solar panels instead of standard rigid solar panels. So what’s the difference between flexible and rigid solar panels and how do you choose a solar panel?
There are pros and cons to both types of solar panels. Flexible solar panels are sometimes superior to rigid solar panels.
Are rigid solar panels more efficient than flexible solar panels?
Rigid solar panels last five times longer than flexible solar panels. Solar panels do not become obsolete after they reach their 25-year life expectancy; rather, their efficiency decreases until they can only provide about 80% of the electricity they were able to provide when they were first installed.
Are flexible solar panels worth buying?
Yes, flexible solar panels are the best long-lasting alternative to rigid solar panels. They can withstand a lot of abuse, are versatile, and have enough power for gadgets and batteries.
The only downside is that they are not as efficient as rigid solar panels and may not survive as long.
Why do flexible solar panels fail?
Flexible solar panels are exactly what their name suggests: solar panels that bend. But “flexible” isn’t folding. Instead, they can usually be bent to some degree. If bent too much, the internal cells and electrical structure can still fail.
After understanding the applicable scenarios and advantages and disadvantages of flexible solar panels and rigid solar panels, we can find that they each have their own characteristics and are suitable for different environments and needs. In the actual selection, you need to consider various factors according to the specific situation in order to choose the most suitable solar panel for you.
