Buying Guide for Flexible Solar Panels

When it comes to choosing a flexible solar panel, there are several factors you should consider to ensure you’re making an informed decision. Here’s a comprehensive buying guide to help you navigate through the options:


The efficiency of a solar panel refers to how well it converts sunlight into electricity. Higher efficiency means you’ll need fewer panels to generate the same amount of power. Look for panels with an efficiency rate above 20% for optimal performance.


Flexible solar panels are generally made from monocrystalline, polycrystalline, or thin-film cells. Monocrystalline cells offer the highest efficiency but come at a higher cost. Polycrystalline cells are less efficient but more affordable. Thin-film cells offer the most flexibility but are the least efficient.

Weight and Size

Consider the weight and dimensions of the panel, especially if you plan to use it for mobile applications like RVs, boats, or camping. Lighter and more compact panels are easier to install and transport.


Look for panels made from durable materials like ETFE to ensure a longer lifespan. Check if the panel is waterproof, UV-resistant, and capable of withstanding various weather conditions.


The bend radius of the panel can be crucial if you plan to install it on uneven or curved surfaces. A lower minimum bend radius allows for more flexible installation options.

Additional Features

Some panels come with extra features like built-in USB ports, charge controllers, or junction boxes. While these can add convenience, they may also add to the cost.

Warranty and Customer Support

Always check the warranty period and what it covers. A longer warranty period is generally an indicator of the manufacturer’s confidence in the product. Also, consider the quality of customer support, as you may need assistance during installation or troubleshooting.


Finally, consider your budget. While it may be tempting to go for the cheapest option, remember that you often get what you pay for. It’s usually worth investing a bit more upfront for a high-quality, efficient panel that will save you money in the long run.

By considering these factors, you’ll be better equipped to choose a flexible solar panel that meets your specific needs and preferences. Whether it’s the Topsolar Flexible Solar Panel 100W or another model, make sure to weigh the pros and cons carefully to make an informed decision. Happy shopping!

Frequently Asked Questions

Are flexible solar panels worth it?

Flexible solar panels offer a unique set of advantages that make them worth considering for specific applications. They are lightweight, easy to install, and can be mounted on irregular or curved surfaces like RV roofs, boats, and tents. However, their efficiency and durability can sometimes be lower than traditional rigid panels. If flexibility, weight, and ease of installation are your primary concerns, then flexible solar panels are definitely worth it. If you can place rigid panels, take a look at my best solar panel for RV article.

What is the highest wattage flexible solar panel?

The wattage of flexible solar panels can vary widely, but they generally range from 50W to 200W per panel. Some specialized or custom-made panels may offer higher wattages, but these are less common in the consumer market. Always check the specifications from the manufacturer for the most accurate information.

Are flexible solar panels as good as solid?

Flexible solar panels are generally not as efficient as their rigid counterparts made of monocrystalline or polycrystalline silicon. Rigid panels can have efficiencies upwards of 20%, while flexible panels usually hover around 17-20%. However, flexible panels offer advantages in terms of weight, ease of installation, and adaptability to irregular surfaces. So, while they may not be “as good” in terms of efficiency, they excel in other areas.

Are flexible solar panels better than regular solar panels?

The term “better” is subjective and depends on what you’re looking for. If you need a lightweight, portable, and easy-to-install option, then flexible solar panels are better for you. They are particularly useful for camping, boating, and other outdoor activities. However, if you’re setting up a long-term solar installation where efficiency and durability are more important, then traditional rigid panels would be a better choice.
