Finding the Best Flexible Solar Panels - Buying Guide

If you’re not that familiar with flexible solar panels, shopping for one may prove to be a challenging task. Like with all other products, there are certain things you need to keep in mind. In the following paragraphs, we’ll provide an overview of important features you need to look out for.

Things to Consider When Choosing the Best Product

Usage

When shopping for a flexible solar panel, one needs to consider what they will be using it for. Are you an avid camper, and need a flexible solar panel for your tent? Or are you, perhaps, an RV enthusiast and need one of these devices for your van’s roof?

Here’s an example – you own a travel trailer and often drive through desert-like areas with high temperatures. In that case, you’ll need a model that withstands high heat. A panel that uses amorphous silicon cells would be the best choice – such models perform better in extreme temperatures. The performance of monocrystalline panels, on the other hand, decreases with high heat.

Or, let’s say you have a large, clean surface on which you want to install a solar panel. For such purposes, models like Uni-Solar PVL-136 PowerBond are the best. They feature a peel-and-stick installation and are the ideal solution.

Versatility

Another important thing to consider is your future model’s versatility. However, flexible solar panels are already versatile by nature and have wide applicability. Nevertheless, there are still some certain bells and whistles that can make your model more versatile.

Ultra-flexible panels, for example, can be installed literally anywhere. Their construction makes them perfect for use on-the-go – you’ll never find yourself in a situation in which you won’t be able to use them. Similarly, waterproof panels allow one to use them in wet/moist conditions. Heavy rainfall won’t be able to damage your model’s sensitive electronics.

Another feature that can make a flexible solar panel versatile is the presence of convenient accessories. If you, for example, purchase a model that comes with a kit of chords of different lengths, you’ll never have to buy any extension cables. The same can be said for units that come together with assembly tools.

Technology

Most of today’s solar panels are made up of blocks of polycrystalline or monocrystalline silicon. These are sliced down into tiny substrates, each of which makes up an individual solar cell. As you can already guess, these are then put together to make a solar panel.

Thin-film, on the other hand, is made differently. The process is similar to that of the printing press – various materials are deposited into a special, bendable substrate. It’s a less expensive method of making PVs (photovoltaics), but also the one that produces less efficient solar cells.

Despite this disadvantage, thin-film panels have a huge benefit – they’re fully bendable, and can even be rolled up in some cases. They’re the ideal option for charging portable electronics.

If you need more power, however, (you want to install your panel on a boat or RV, for example), select a model made of bendable crystalline solar. These are less flexible than their thin-film counterparts (only up to a 30-degree angle) but can still be installed on most curved surfaces.

Efficiency

When talking about the efficiency of these devices, the term refers to how fast a particular model can convert sunlight into electricity. As you can see in our roundup of the market’s most popular flexible solar panels, efficiency varies from one model to another – some are more efficient than others.

However, most units don’t move out of the 10% -25% range. The higher this percentage is, the faster you’ll be able to use the energy harnessed from the sun. Flexible panel technology has gotten significantly better in the last decade, so even the budget-oriented models offer impressive efficiency.

If you’re planning to use your model to charge only smaller electronics, such as smartphones and tablets, efficiency doesn’t have to be among your top priorities. You will, however, need one with a high conversion rate if you’re planning to use it for charging your RV’s battery, for example.

Important Features to Look For

When buying a flexible solar panel, two essential factors you need to consider are size and weight. These will mostly depend on how and where you want to use the device. If you, for example, want to use your panel on to go, for charging smaller electronic appliances, choose a model that's compact and lightweight. This is particularly important if you're a hiking enthusiast - you don't want to add any extra weight to your backpack. If you intend to use it in a larger space, however, feel free to purchase a larger, more powerful unit.

The primary aim of purchasing one of these devices is obtaining free electricity. Therefore, it's crucial to look out for models with higher power output. A unit with more watts (W) will let you harness more energy from sunlight. DOKIO 300w Panel Kit, for example, offers top performance for a flexible solar panel. An important thing to mention here is that most flexible models aren't that good for home rooftop solar projects. While powerful enough for smaller, mobile projects, they don't provide the same amount of energy as their stationary counterparts. For RVs or boats, on the other hand, they're a perfect fit.

Durability is a very important factor. The reason behind this is in the fact that flexible models are often used for mobile solar projects, where they often experience physical wear and tear. As you already know, this is not something that occurs on stationary roofs, at least not in the same amount. For that matter, we recommend choosing a model with durable construction. Make sure to select a unit that's resistant to things like dust, rain, and extreme temperatures. Moreover, try to obtain a panel that's waterproof - its junction box needs to be sealed and protected from moisture.

The efficiency of the cells present in your model will depend on its type. As we already mentioned, monocrystalline panels provide a higher conversion rate than their thin-film counterparts. However, they're not as flexible - most models can be bent only up to a 30-degree angle. Remember that models with a higher efficiency rating can convert more sunlight into usable electricity. The future usage of your flexible solar panel should dictate its efficiency - it's as simple as that. You'll wish to have a highly efficient model if you're planning to use it for something more than just charging your phone.

Obviously, flexibility is the primary selling point of these products. As they're bendable, they can be installed on curved surfaces, such as the curved roofs of travel trailers. Once again, flexibility depends on the type. Thin-film models are more flexible, and can sometimes even be rolled up. A good example is the Uni-Solar PVL-136 Powerbond, which comes rolled up in a box. However, most of the models in our roundup aren't that flexible. Still, each one of them can be easily installed on all sorts of curved and irregular surfaces. Based on monocrystalline technology, they're also more efficient.

How to Install Flexible Solar Panels?

After deciding which flexible solar panel to purchase, the next question will be how you can install it. Fortunately, you won’t require any professional help – it’s something you can easily do by yourself.

Most of the time, installing a flexible solar panel is exceptionally easy. It’s a simple and straightforward process once you choose the place where you want it installed. You will, however, need to make sure that it doesn’t fall off in case of bad weather, such as a hailstorm or heavy snowfall.

Most of the models we’ve analyzed come with pre-drilled grommets. While some people don’t mind drilling any surface to install the panel, some individuals aren’t that comfortable with it.

This is especially true when it comes to RV roofs and boats. If that’s the case, remember that you can always purchase a backing of plywood. Rather than drilling holes through your vehicle, screw the panel to the plywood.

Another way to install a flexible solar panel would be to use a tape or adhesive glue. In fact, some models were designed to be installed this way – Uni-Solar PVL-136 PowerBond is a good example.

Once the installation process is over, you’ll be able to set up the system. If you’re unsure how to do this, make sure to check the user manual you’ve got with your model. Nevertheless, the installation is usually (if ever) the hardest part – using one of these devices is fairly simple.

FAQ

Q: What are flexible solar panels most useful for?

Probably the best application for flexible solar panels comes up in situations when you need solar power on the go. Flexible panels are a way to generate electricity from the sun while you’re out and about, such as on your RV or boat. If you need portable and lightweight power, and you enjoy a lot of camping trips, you may also want to consider folding solar panels.

All things considered, flexible panels are great for when you’re driving long distances, camping, or sailing. It’s hard to beat a flexible and lightweight, yet durable solar solution in a situation like that.

Q: Are flexible solar panels less efficient?

In many ways, flexible panels are superior to their rigid counterparts. They are thinner and lighter and can bend as their name implies. They work very well for those applications when the weight and stiffness of a traditional solar panel would not suffice. 

While all of this is true, flexible solar panels can also be slightly less efficient. This is usually due to the way they are mounted. As traditional panels are typically raised a few inches off the surface, they allow more airflow, thus keeping their temperature low and efficiency high. Flexible panels are usually laid flush against the surface, which somewhat diminishes their productivity.

Q: How much does the average flexible panel weigh?

There are many factors to consider when answering this question, and it is going to be challenging to give a definitive answer. What we can say, though, is that flexible panels are, on average, about 75% lighter than their stiff counterparts.

For example, a 100W rigid panel may weigh from 16 to 20 pounds, while a flexible panel with the same power capabilities may weigh only 4-5 pounds. This is a massive factor for those who need a lightweight solution. The downside is the somewhat lower efficiency and the possibility of overheating that comes with flexible panels.

Conclusion

Bendable to a certain degree, flexible solar panels are a perfect option for anyone who owns an RV, a boat, or a tent. Once installed on a curved surface of your choice, your model will convert the sunlight into usable electricity. In most cases, the power is not sacrificed for flexibility – these devices are just as efficient as their rigid counterparts.

To help you select one that will suit your needs, we’ve rounded up and analyzed some of the market’s most popular offerings. Hopefully, you’ll be able to make an informed decision and start saving money by harnessing sunlight. Good luck!
