Pros and Cons of Flexible Solar Panels

Flexible solar panels are becoming more popular as they become cheaper to produce by the day. Not only that, but they also have many benefits that make them an attractive option for homeowners.

However, there are some downsides that you should consider before buying flexible solar panels.

In this article, we’ll cover all the pros and cons of flexible solar panels so you can decide if they’re right for your home. Let’s get started!

What Are Flexible Solar Panels?

Before getting into the pros and cons of these panels, let’s first look at exactly what they are. Flexible solar panels are similar to standard photovoltaic cells in converting the sun’s energy into usable electricity. In this respect, you could call them a type of photovoltaic power system.

However, their design is what makes them unique. Flexible solar panels are made from ultra-thin, bendable material that can be attached to nearly any surface. They don’t have to remain flat against your roof or ground to produce electricity. Instead, you can curve or roll them up to follow the shape of whatever surface you attach them to.

This also means you can pull them in and out of the sun as it moves across the sky, maximising their exposure. They’re even strong enough to stand up against wind and rain when attached to a vertical surface!

With that said, let’s examine their main pros and cons.

Pros of Flexible Solar Panels

Why would you want to use flexible solar panels instead of standard ones? Well, quite a few benefits make them an attractive option for homeowners. Here are just a few:

Portability

Thanks to their lightweight and thin design, flexible solar panels are easier to transport, so you can relocate them if necessary. This is great for putting them in a sunny spot on days when you need extra power or moving them to a shadier spot when you don’t need as much power.

Flexible solar panels are also rolled up or folded when not in use, making them easy to store!

Versatility

You can attach flexible solar panels to nearly any surface, which gives you a great deal of flexibility when placing them. They even come in different colours and shapes to choose one that best suits your needs.

In addition, the placement of these panels allows you to use whatever surface they’re attached to to gather solar energy. For instance, if you attach them to the roof of your shed, you could then use that roof as a partial shelter for storing your lawnmower and any other tools!

Convenient Installation

One of the greatest benefits of using flexible solar panels instead of standard ones is that they’re much easier to install. This means you sometimes don’t need the help of an experienced professional to get them set up in no time!

All you have to do is find a surface that gets plenty of sunlight throughout the day, then attach these panels to it using magnets or some other adhesive (yes, they have adhesive backing!).
This also means you could attach them to a fence or backyard shed to turn it into a mini power station.

Once you’ve done that, flip the switch, and they should start working like a charm!

Low Cost

Since flexible solar panels don’t require a complicated mounting system, they’re often much cheaper than standard ones. On top of that, their manufacturing costs are dropping faster than standard solar panels, so you can expect to save even more in the long run.

This is great news for homeowners on a tight budget who want to add extra power to their homes!

Semi-Transparency

One of the greatest benefits of adding flexible solar panels to your home is that they’re semi-transparent. This means you can place them against a window or any glass and still be able to see through them. This is great because you don’t lose the view while gaining extra power.

Cons of Flexible Solar Panels

While flexible solar panels have plenty of benefits, a few drawbacks should give you pause before making a purchase. Let’s take a look at some of them:

Their Adhesiveness Makes Them Less Secure

While the adhesive backing makes it easy to attach these panels to any surface, this same property means they’re not as secure. If they get bumped or moved out of place, they can come loose and slip off their given surface. And once they reach the ground, you may never be able to retrieve them.

Less Durability and Shorter Lifespan

Flexible solar panels are more likely to suffer damage than standard ones because their material makes them thinner, weaker, and more fragile. This means they can crack or break more easily, dramatically reducing their lifespan. On average, their lifespan is around 10 to 15 years, half of what you’d get with rigid solar panels.

Subpar Warranties

Flexible solar panels come with shorter warranties than ridged solar panels. Sometimes, you’ll only get a ten-year warranty instead of a standard 25+ years! This is because the warranty is tied to the lifespan of the panels, not your home or how you use them. Because they won’t last as long, the company can’t offer you a lengthy warranty either.

This not only means that their durability is in question but also makes them less valuable.

They Can Be Toxic

The chemicals used to make some flexible solar panels are more harmful than those used in standard panels. They’re also harder to recycle and dispose of at the end of their lifespan.

For instance, CdTe panels contain toxic cadmium, and while “safe” levels of exposure exist, prolonged exposure could be dangerous. So, if your kids play near these panels or you frequently touch them with your hands, there might be a higher risk for cadmium poisoning than other types of solar panels.

Plus, when it’s time to dispose of them, they could also be very harmful to the environment, so make sure you dispose of them properly to avoid that.

Low Efficiency

Lastly, the biggest problem with flexible solar panels is that they’re less efficient than standard ones. Their average efficiency rates fall between 10% and 17%, while you can expect efficiency between 16% and 23% with rigid panels.

That means you have to buy more panels to produce the same amount of electricity, increasing your cost.

Case Study: Implementing Flexible Solar Panels in a Residential Setup

Background

A homeowner in the UK sought to install solar panels on their curved, metallic roofing. The unique architecture of the home made traditional solar panels impractical, prompting the exploration of flexible solar panel solutions.

Project Overview

The objective was to install a solar panel system that could efficiently generate electricity while conforming to the roof’s curved surface. The homeowner was particularly interested in the aesthetic appeal and ease of installation offered by flexible solar panels.

Implementation

• Assessment and Planning: Our team conducted an assessment to determine the best placement for the flexible panels, ensuring maximum sunlight exposure throughout the day.
• Selection of Panels: Flexible solar panels with high efficiency and a suitable aesthetic were selected. The panels chosen were semi-transparent, allowing light to filter through while providing shade to the underlying area.
• Installation Process:
  • Surface Preparation: The roof was cleaned thoroughly to ensure proper adhesion of the panels.
  • Adhesive Application: The panels were secured using a specialized adhesive suitable for metal surfaces, ensuring a strong bond without damaging the roof.
  • Wiring and Connectivity: The panels were wired to a central inverter located inside the house, converting the DC electricity generated into usable AC electricity.

Results

• Energy Production: The flexible solar panels achieved an efficiency rate of approximately 15%, providing sufficient energy to power most of the home’s lighting and small appliances.
• Aesthetic and Functional Benefits: The semi-transparent nature of the panels added an attractive feature to the home’s exterior while also providing shade and reducing heat absorption on the roof.
• Cost Efficiency: The total installation cost was lower than a traditional solar setup, primarily due to the ease of installation and the lack of need for a mounting system.
