How to Select the Best Flexible Solar Panels?

There are many flexible solar panels with the same claim of being the best. Hence, making the best decision can be such a headache, but when you are aware of what to look out for, making a choice becomes much easier and not so dreadful. Consider the following factors before making a buying choice:

Size and Weight of the Solar Panel

This is an essential factor to consider before buying a solar panel. If you intend using your panel in a smaller space, then you may want to purchase a solar panel that is smaller and also lightweight. On the other hand, if you intend using it in a larger space, the size may not matter much. However, the choice of a smaller solar panel makes it easy to transport and install.


The main aim of buying a solar panel in the first place is to obtain light; it is therefore essential to look out for solar panels with a high power outage. A panel with lower watts means there will be less power output and you may need to connect several panels to get the desired power output that is sufficient for you, while a solar panel with high watt means the energy output will be high and hence will serve your needs better.


If you are on the lookout for a flexible solar panel, then you shouldn't go for less than the best. However, the level of flexibility of solar panels differs from one solar panel to the other. The best way to judge how flexible a solar panel is is by measuring the degree, or how far it can bend without the fear of the panel breaking. This feature is essential, especially if you are going to be mounting your solar panel on curved, irregular surfaces.


As the solar panel is mostly used outdoors where it is exposed to rain, dust, and sunlight, you should go for a panel that is resistant to adverse weather conditions as this will make it last longer. To enable your solar panel last a long time, it is essential also to consider the material used in constructing these solar panels and ensure that the quality corresponds to the durability to get value for your money.

Cell Efficiency

This refers to how fast the solar panel can convert energy absorbed from sunlight into energy that can be used. This is usually within a range of 11% to 21%. The higher the percentage of conversion, the faster you can get to use the energy tapped from the sun. Hence, the need to purchase a solar panel with high cell efficiency is essential if you wish to have quick and effective energy.

Ease of Installation

This may seem an insignificant factor but its equally important, especially if you are not familiar with how to install a solar panel. Purchasing a solar panel that is simple and easy to install will save you a lot of stress and will not consume so much of your time.


It is equally important to look out for additional accessories that come with your solar panel. You may purchase one with a short cord; in that case, you will need to buy an extension as the cord is not long enough. Check too if your solar panel comes with an assembly tool, if it doesn't then you will need to buy one. Check if there are other additional accessories you will need to purchase, this will ensure you enjoy the use of your solar panel better.


This refers to partial security you get on the investment of any product. It should be noted that flexible solar panels do not have a lifetime warranty on their products, unlike most conventional solar panels. For flexible solar panels, most manufacturers only offer about one to a two-year warranty, thereby leaving their customers vulnerable. In spite of this, you can always find flexible solar panels that provide as much as a five-year warranty on their products.

How to install flexible solar panels?

After making a choice on the type of solar panel to buy, the next question will be how to install the flexible solar panel. You need not contact an expert as it is something you can do yourself; all it takes is a surface.

Most times, the process of installation is quiet simple and straightforward depending on where you wish the panel to be installed. If you purchased a flexible solar panel with a pre-drilled grommet then you are just in luck. However, to ensure the solar panel wont fall off especially during heavy rain or wind, its best to screw down the solar panel to the surface.

While some do not have a problem screwing down their solar panel to any surface, some people are not comfortable with this. If you belong to the later group then you can get a backing of plywood where the solar panel can be screwed on rather than drill holes through your boat, roof or RV.

You could also use adhesive glue or a tape to hold the panel tightly to the surface. This would ensure the panel doesn’t come off. Once you are done installing, set up the entire system, (you can discover how that is done in the manual that comes with the solar panel). Thereafter, your solar panel is ready to use; you can now enjoy uninterrupted power supply at a cheaper and cost effective way.
