What is a Flexible Solar Panel?

Flexible solar panels have other names:

  • Portable/Transportable Solar Panels
  • Lightweight Solar Panels
  • Stick On Solar Panels
  • Soft Solar Panels
  • Bendable Solar Panels
  • Semi-Flexible Solar Panels

No matter what the name is, these flexible solar panels have the same function, convert solar energy into power. Flexible solar panels are usually made of polycrystalline or monocrystalline cells, both of which are designed to collect sunlight and turn them into usable energy.

In terms of function and purpose, flexible solar cells are not that different from traditional ones, except they’re lighter. The easy installation and set up also makes it more cost effective.

Flexible Solar Panels vs Traditional/Hard Solar Panels – What’s The Differences?

This flexible solar panel review can easily highlight the difference between these two types of solar panels.

  • Setup: flexible solar panels are installed via Velcro, zip ties or adhesive. Traditional solar panels need structural or solid fixing.
  • Material Composition: soft solar panels are comprised of plastic or other lightweight materials. Rigid solar panels are made of aluminum, glass or other materials.
  • Susceptibility: traditional solar panels are vulnerable to cracks and breaking. Flexible solar panels on the other hand, are susceptible to scraping and pointy objects.
  • Versatility: traditional solar panels only work on flat surfaces, while flexible solar panels can be installed on different types of surfaces.
  • Efficiency: the efficiency level varies. It depends on the specifications and not whether it is flexible or traditional.
  • Weight: traditional solar panels weigh more because of the materials it uses.
  • Ease of Installation: flexible solar panels are easier as they’re lighter. They’re also the option if you want to equip your vehicle with solar power.

Traditional and soft solar panels differ in other ways, but the stuff above are the most important characteristics.

What is a Flexible Solar Panel Used For?

The primary purpose of a flexible solar panel is provide you with another energy source. But its uses and benefits extend beyond that.

  • Solar power is used as a source of renewable energy. Unlike oil, sunlight isn’t going to run out for billions of years. You can use solar energy over and over and it’s not going to run out.
  • A source of clean energy: flexible solar panels do not cause pollution. They’re just as effective as oil, coal and other sources but without causing pollution.

What Does a Flexible Solar Panel Do?

A flexible solar panel is used as an alternative to aluminum, glass and other hard solar panels.

Bendable, flexible and semi-flexible solar panels are installed on homes, RVs, camp sites, tents and other structures. Like rigid solar panels, they convert sunlight into electrical power.

Flexible solar panels come in various styles, but they serve the same purpose, generate power. The fact that they’re bendable or flexible means it is suitable for unusually shaped surfaces, something rigid solar panels can’t handle.

A flexible solar panel has many uses, but basically it’s going to save you money and serve as an alternative energy source.

Types of Flexible Solar Panels

Ways of mounting flexible solar panels depend on the type you buy. These devices come in various styles but the most common are the following.

  • Bendable: a bendable solar panel may be curved up to 30 degrees, though some are limited to 10 degrees. Bendable solar panels are most suitable for irregular surfaces and those with curvatures.
  • Semi-Flexible and Flexible: these solar panels are flexible to a degree but you cannot curve or bend them.
  • 50 Watt Solar Panels: bendable, flexible or semi-flexible solar panels with a maximum of 50 watts of power.
  • 100 Watt Solar Panels: bendable, flexible or semi-flexible solar panels with a maximum of 100 watts of power.

The type of solar panel to get depends on your preference and where you plan to install it. You also need to consider if you’ll be installing the panels on an RV.

Flexible Solar Panel Bits & Accessories

Flexible panels work great on their own, but sometimes you need some accessories to enhance its functionality. Here are the top accessories and attachments you can get your solar panel.

  • Cable Extension: you’ll need this if the cable on your flexible solar panel isn’t long enough.
  • Cable Connectors: solar panels have connectors, but it won’t hurt to have an extra pair of MC4 cables lying around.
  • Solar Charge Regulator Display: this device sets the withdrawal and addition of electric currents. This is also an important feature for discharges, charges and overshooting.
  • Solar Panel Assembly Tool: you’ll need this to install and uninstall the solar panels. The panels may be bundled with one already though.

You’ll probably come across other accessories, but these are the essentials. If you buy a well made flexible solar panel these accessories may already be included.

How to Choose a Flexible Solar Panel

Here are some of the factors you may want to consider.

  • Energy Extraction Efficiency: how efficient is the panel in obtaining sunlight? This tells you how useful the panel is in real life situations.
  • Installation: look for solar panels that are easy to set up. Think also of the size and if you plan on adding more in the future. Is a DIY installation possible or is a professional required?
  • Degree of Flexibility: some panels are really flexible while others don’t bend as much. The choice depends on the type of roof you have and your preferred style.
  • Wattage: there are two options, 50W or 100W. Higher wattage means more power and better performance.
  • Resistance Level: what resistance do the panels provide against snow, rain, hail, air, heat and water?
  • Weight: the panel’s weight becomes an issue if you’ll be doing the installation.
  • Junction Box: the junction box should be protected and sealed.
  • Surface Adherence: what surfaces can you put the panel on? This question becomes important if you plan to install the panels on your RV, tent, cabin or other surfaces.

Features to Look for in a Flexible Solar Panel

Flexible solar panels for home use come in different styles, shapes and sizes, but the structure and configuration varies.  Here are some features you’ll want to check out.

  • Solar Cell Type: the majority of flexible panels are made of monocrystalline as they’re very efficient. Some of the better models have electrical connectors and components that improve its solar gathering capability.
  • Power: look up its power output online or at the rear of the panel. The key figures are volts, amps and watts.
  • Quality: buy only flexible panels that have been evaluated in Standard Test Conditions. This provides assurance the panels match the minimum requirements.
  • Front and Back Materials: most flexible panels have a solid white back and laminated front layer. Some flexible panels use ETFE (Ethylene Tetrafluoroethylene) as it is more durable.
  • Durability: while flexible panels are flexible, that doesn’t mean you should bend them incessantly.
  • Portability: lightweight flexible panels are easier to set up and more comfortable to transport. It’s for this reason why ETFE has become more popular now.
  • Cleaning and Maintenance: a well made flexible panel won’t need a lot of cleaning so it’s more convenient to use.
  • Anti- Heating Elements: some flexible panels generate a lot of heat during operation. Look for those that have aluminum backing to reduce heat.
  • Connectors and Connections: MC4 connectors are ideal for DIY flexible panels. As for cable length it can be 10 inches or 6 feet, it varies.

Flexible Solar Panels Advantages and Disadvantages

Flexible solar cells continue to gain popularity, but are they really worth getting? Let’s examine the pros and cons.
