How Do Flexible Solar Panels Work?

As far as solar technology goes, flexible solar panels work in the same way that rigid panels do. The question then becomes: How do solar panels work in general? Solar panels convert the energy of photons (light particles) into electricity through a process called the photovoltaic effect.

When a photon hits a solar module, its energy causes electrons to flow within the solar cells, producing an electric current. The resulting electricity is direct current (DC) power, which is commonly used in battery-powered devices. For household or commercial use, the DC power is converted into alternating current (AC) electricity with an inverter.

Types of Flexible Solar Panels

The heart of a solar panel is the cell, so let’s start there. Here are how the types of flexible solar panels differ:

• Monocrystalline cells are made of a solid silicon crystal. Mono cells allow greater electron flow, resulting in a smaller, high-efficiency panel. But they tend to be more expensive.
• Polycrystalline cells are made from many individual shards of silicon. They’re not as efficient as mono solar energy cells, but poly cells come at a lower price point.
• Thin-film cells can be poly or mono, but they are up to 300 times thinner than their rigid counterparts. Apart from obvious benefits of flexibility, thin-film panels can provide better low-light performance than rigid panels. However, they tend to be less efficient overall.

What Are the Benefits of Flexible vs. Rigid Solar Panels?

A typical monocrystalline or polycrystalline solar panel is constructed of silicon wafers that are generally a bit thicker than a strand of human hair. Although it’s relatively thin, the layer is rigid and easily broken, requiring most solar cells to be protected with metals and glass casings.

Flexible solar panels belong to a family of solar products called “thin film panels.” Flexible panels are constructed with silicon layers over 300 times smaller than those of standard solar panels, allowing them to be flexed and still retain their functionality.

The greatest obstacle for flexible solar panels is that they’re much less efficient than rigid panels. Today’s average rigid solar panels are about 16-20% efficient. Thin-film flexible solar panels, however, are only 7-15% efficient, meaning you’ll need more of them to produce the same amount of electricity a rigid panel would produce.

Flexible solar panels probably won’t fit the bill for rooftop energy production, but they’re a great option for anyone needing lightweight and portable power. Durable and lightweight, flexible solar panels are ideal for small-scale, mobile applications such as for RVs, boats and other energy needs that don’t require large power outputs.

How Much Do Flexible Solar Panels Cost?

Flexible solar panel costs vary depending on size, quality, efficiency, durability, materials, capacity, features and even brand name. Ranging from $150 for a single 100-watt panel up to $1,000 or more for multiple-panel units, flexible solar panel options exist for any on-the-go need and budget.

At the end of the day, it’s not essential to buy the absolute best solar panels on the market, but we don’t advise trusting your off-grid power to any old cheap model you see on Amazon.

What Should You Look for When Choosing a Flexible Solar Panel?

Now that you’ve got an idea of how flexible solar panels work and the top models available, you may be interested in making a purchase. When you’re ready to buy solar panels, here are a few things to keep in mind to narrow down the best options for your power needs and budget.

Design and Size of Flexible Solar Panels

To start, determine the space you plan to place your new flexible solar panel. If it’s a relatively large space (an RV roof, for example), you’ll have more options to choose from. If it’s a small space or an irregular surface, you’ll want to look for more efficient, high-capacity panels.

You’ll also need to consider if the space you plan to install on is flat or curved and whether it contains obstacles or obstructions. The good news is a slightly curved surface is usually no problem for flexible solar panels. If your installation space has a pronounced curve, make sure you purchase a flexible solar panel with enough range of motion.

Wattage for Flexible Solar Panels

The higher a solar panel’s wattage, the more electricity it can produce under the same conditions. To accurately calculate how many solar panels you need, compare the daily output of the solar panel with the needs of the appliances or devices you want to power with solar energy.

Flexible Solar Panel Efficiency vs Standard Solar Panels

Overall, flexible panels are less efficient than rigid ones, but they do tend to perform better in low-light situations. If you choose a less-efficient panel like the flexible solar panels, you’ll need more panels to produce the same amount of energy a more-efficient panel would.  Where you live also plays a role in solar panel efficiency. Check the Renewable Resource Data Center for sunlight information for states and major cities.

On avg a standard solar panel will produce 20% energy efficiency while a flexible one might produce 8% less than that. Nothing inherently wrong with that, but do expect to buy more flexible panels for the same energy output.

Installation Process for Flexible Solar Panels

Thankfully, flexible solar panels are extremely easy to install. Many flexible solar panels on the market come with adhesive backing and plug-and-play components, making it easier than ever to install your new solar system.

Durability of Flexible Solar Panels

If you’re in the market for a flexible solar panel, chances are you need it to stand up to the rigors of the road, water, or trail. Flexible solar panels are among the toughest options on the market, with most offering excellent weatherproofing, flexibility, and calculated construction to stand up to conditions a rigid panel wouldn’t.

Flexible Solar Panel Pricing

Cost is usually the limiting factor when choosing a flexible solar panel. If you’re looking for something to power small electronics or keep your batteries topped off, you don’t need to break the bank. For less than $250, you can get a ready-to-install kit ready.

But a bit more power comes with a larger price tag. Purchase only what you need, and scale up by stringing panels together or upgrading your system if your needs grow.
