Pros and Cons of Rigid and Flexible Solar Panels

Are rigid or flexible solar panels better? Or should you use both?


Incorporating solar panels into your caravan or camping set-up is an excellent way to produce power on the go without requiring access to grid power. With solar panels, you can travel off-grid and get away from the crowds at powered campsites. 

12V or 24V solar panels convert energy from the sun into electricity to be stored in your auxiliary batteries. You can then discharge this electricity to power your appliances, including fridges, stovetops, coffee machines, lights, and other home conveniences while on the road.

There are two types of solar panels that you can incorporate into your set-up - flexible solar panels and rigid solar panels. Which type should you choose? Which is better? Or should you incorporate both into your system? 

While both can harness the sun’s energy, they differ significantly in design, efficiency, durability, and long-term value. We’ll discuss the pros and cons of rigid and flexible solar panels so you can decide how you would like to utilise solar energy. Read more to compare solar blankets vs solar panels.

Difference between flexible panels and rigid panels

A flexible solar panel, as the name suggests, is bendable and lightweight. These panels are often used in portable applications, such as camping, boating, or temporary setups. There are a few types of flexible panels, including solar blankets, which can be folded or rolled up for storage, and thin-film panels that can be attached to curved surfaces.

On the other hand, rigid solar panels are the traditional, framed panels that are often roof-mounted to caravan, motorhome, or boat decks. They are designed for permanent installation and provide high efficiency and longevity. Another option within the rigid panel range is a solarcase, which consists of a rigid panel encased in a portable, foldable design. A solarcase successfully melds the durability of a rigid panel with easy storage capability like that of a flexible solar panel.

Pros and cons of flexible solar panels

Pros

  • Easy to store - Flexible panels can be rolled up or folded, making them convenient for transport and storage.
  • Lightweight - Their low weight makes them easy to carry and set up, especially for outdoor adventures.

Cons

  • Less powerful - Flexible panels typically generate less power compared to rigid panels of the same size.
  • Fragile - Without a solid frame, these panels are more prone to damage, such as cracking, punctures, or delamination over time.
  • Shorter lifespan - They degrade faster due to exposure to the elements, reducing their efficiency and longevity.
  • Requires frequent setup - Since they aren't permanently installed, you'll have to set them up and position them every time you need solar power.

Pros and cons of rigid solar panels

Pros

  • More powerful and efficient - Rigid panels have higher efficiency ratings, meaning they generate more power for the same amount of sunlight.
  • Sturdy and durable - Built with a solid frame and tempered glass, they can withstand tough Australian weather conditions, sand, and salt.
  • Long lifespan and warranty - Most rigid panels are supported with longer warranty periods than their flexible solar panel counterparts, ensuring long-term performance and value.

Cons

  • Permanent installation required - Rigid panels are typically mounted on rooftops or structures, requiring installation effort. However, if you need portability, a solarcase offers a compact alternative. 
  • Heavier and harder to store - Due to their solid construction, rigid panels are bulkier and less convenient to transport compared to flexible panels.

Should you combine flexible and rigid solar panels into your setup?

Sure, but we’ll tell you what we tell all our customers. If you’re serious about solar energy, investing in a permanent setup will give you the best return. For those who need portable solar, a solarcase provides a much better alternative—offering durability, efficiency, and ease of use. In the long run, rigid panels simply make more sense: they last longer, generate more power, and are built to withstand the test of time.
