Flexible solar panels: everything you need to know

From digital nomads to outdoor adventurers, flexible solar panels are a great option for providing clean, renewable energy wherever life takes you. But with so many options to choose from, how do you know which model is the best option for you?

In this article, we’ll go over what flexible solar panels are, how they differ from rigid solar panels, and which is best for your needs.

Flexible solar panels vs rigid solar panels.

A typical monocrystalline or polycrystalline solar panel is constructed with wafers of silicon that are typically slightly thicker than a human hair. Although relatively thin, the layer is rigid and breaks easily, requiring most solar cells to be protected by metal and glass envelopes.

Flexible solar panels belong to a family of solar products called “thin film panels”. The flexible panels are constructed with layers of silicon more than 300 times smaller than standard solar panels, allowing them to flex while maintaining their functionality.

The biggest hurdle for flexible solar panels is that they are much less efficient than rigid panels. Current rigid solar panels have an average efficiency of between 16 and 20%. However, flexible thin-film solar panels are only 7-15% efficient, meaning it will take more to produce the same amount of electricity as a rigid panel.

Flexible solar panels are probably not suitable for rooftop power generation, but they are a great option for anyone who needs lightweight, portable power. Durable and lightweight, flexible solar panels are ideal for small-scale mobile applications such as RVs, boats, and other power needs that don’t require a lot of power.

How do flexible solar panels work?

When it comes to solar technology, flexible solar panels work the same way as rigid panels. The question then is: how do solar panels work in general?

Solar panels convert the energy of photons (particles of light) into electricity through a process called the photovoltaic effect. When a photon strikes a solar module, its energy causes electrons to flow through the solar cells, producing an electric current.

The resulting electricity is direct current (DC), which is commonly used in battery-powered devices. For domestic or professional use, direct current is converted into alternating current with an inverter.

Types of solar panels.

The heart of a solar panel is the cell, so let’s start there.

Monocrystalline solar cells are made from a solid silicon crystal. Monocrystalline cells allow for a greater flow of electrons resulting in a smaller, more efficient panel. But they tend to be more expensive. Polycrystalline cells are made up of several individual pieces of silicon. They are not as efficient as monosolar cells, but polycrystalline cells have a lower price.

Thin-film cells can be polycrystalline or monocrystalline, but they are up to 300 times thinner than their rigid counterparts. Along with the obvious advantages of flexibility, thin-film panels can provide better low-light performance than rigid panels. However, they tend to be less effective overall.

But this is something that can be solved in a very short time thanks to perovskite, and in Poland the world’s first industrial line of perovskite-based solar panels has already been put into production. Photovoltaic panels coated with perovskite are lightweight, flexible and can be easily attached to almost any surface to generate electricity even inside buildings.

How much do flexible solar panels cost?

Flexible solar panel costs vary depending on size, quality, efficiency, durability, materials, capacity, features, and even brand. From $150 for a single 100-watt panel to $1,000 or more for multiple-panel units, there are flexible solar panel options for every need and budget.

How to choose the best flexible solar panel.

Now that you have an idea of ​​how flexible solar panels work and the best models available, you might be interested in buying one. When you’re ready to buy solar panels, here are some things to consider to narrow down the best options for your energy needs and budget.

Design and size.

To begin, determine the space where you plan to place your new flexible solar panel. If it is a relatively large space (the roof of a caravan, for example), you will have more options to choose from. If you’re dealing with a small space or an uneven surface, you’ll want to look for larger capacity, more efficient panels.

You will also need to consider whether the space you plan to install it in is flat or curved and if it presents any obstacles when setting it up. The good news is that a slightly curved surface is usually not a problem for flexible solar panels. If your installation area has a sharp curve, be sure to purchase a flexible solar panel with sufficient range of motion.

Power.

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

Efficiency.

In general, flexible panels are less efficient than rigid panels, but they tend to perform better in low-light situations. If you choose a less efficient panel, you will need more panels to produce the same amount of energy that a more efficient panel would produce.

Remember that where you live also influences the efficiency of solar panels.

Ease.

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

Sustainability.

If you’re looking for a flexible solar panel, chances are you need one that can withstand the rigors of the road, water, or trails.

Flexible solar panels are some of the strongest options on the market, with most offering excellent weather resistance, flexibility and construction calculated to withstand conditions that a rigid panel might not.

Cost.

Cost is often the limiting factor when choosing a flexible solar panel.

If you’re looking for something to power small electronics or keep batteries charged, you don’t have to break the bank. For less than $250, you can get a ready-to-install kit.

But a little more power comes at a higher price. Buy only what you need and expand it by chaining panels or expanding the system if your needs grow. You can still add panels to a parallel installation.

FREQUENTLY ASKED QUESTIONS: Flexible solar panels.

Are flexible solar panels any good?

Yes, modern flexible solar panels are a great sustainable alternative to rigid panels. They can take a lot of beatings, are adaptable, and provide plenty of power for small devices and batteries. The only downsides are that they are slightly less efficient than rigid panels and may not last as long.

Do flexible solar panels last as long as regular solar panels?

In general, no, flexible solar panels do not last as long as conventional solar panels. Rigid panels last between 25 and 40 years. The flexible panels retain their functionality between 15 and 25 years.

Can you walk on flexible solar panels?

Most flexible solar panels are passable. Check with the manufacturer if your panel can be walked on and if this will void the warranty.

What are the best flexible solar panels?

The best flexible solar panels have a high degree of flexibility, durability, and low-light conversion. A good example is the Renogy 175W flexible solar panel.
