Solar panels are devices that use sunlight to convert it into electricity, providing a clean, renewable source of energy. However, traditional solar panels are usually rigid and mounted on the roof of a house or other fixed location, making them difficult to carry and move.
To solve this problem, foldable solar panels have been created. Foldable solar panels are solar panels that can be folded or rolled up and are lightweight, flexible, and durable, and can be used in a variety of situations and environments. This article will introduce the working principle, types, advantages and disadvantages, and applications of foldable solar panels.
How foldable solar panels work
Foldable solar panels work on the same principle as ordinary solar panels, by absorbing the energy from the sun and converting it into an electric current that is charged by a charge controller connected to the device’s battery. The difference is that foldable solar panels use a type of thin-film solar cell. These cells are made from one or more layers of semiconductor material covered with a flexible substrate that is only a few hundred microns thick and can be bent and folded.
Currently, the common thin-film solar cells are copper indium gallium selenide (CIGS), amorphous silicon (a-Si), and cadmium tellurium (CdTe). In recent years, an organosilicon cell has also emerged that uses organic materials as the semiconductor layer, offering greater flexibility and transparency.
Types of foldable solar panels
Depending on the degree of foldability and shape, folding solar panels can be divided into the following types:
Simple: This type of foldable solar panel puts together several thin-film solar cells that can be folded into a small package along the seams. This type of foldable solar panel is cheap but less efficient and is suitable for charging low-power devices.
Briefcase: This type of foldable solar panel has multiple thin-film solar cells mounted in a rigid or soft housing that can be opened and closed like a briefcase. This type of foldable solar panel is strong and efficient and is suitable for charging medium-power devices.
Rolled: This type of foldable solar panel makes a long strip of thin-film solar cells that can be rolled up and unrolled like a roll of paper. Flexible and efficient, this type of foldable solar panel is suitable for charging high-power devices.
Pros and cons of foldable solar panels
| Pros | Cons |
| Lightweight: Foldable solar panels generally weigh less than a few kilograms, making them lighter than traditional solar panels and easier to carry and transport. | Efficiency: The efficiency is lower compared to traditional solar panels, which means that in order to generate the same amount of electricity, foldable solar panels require a larger area. |
| Flexible: Foldable solar panels can be folded or rolled up as required to suit different shapes and spaces, and can be used on a variety of surfaces such as car roofs, tents, backpacks etc. | Cost: Foldable solar panels are more expensive to manufacture, resulting in a higher price tag. In general, foldable solar panels are twice or three times more expensive than conventional solar panels. |
| Durable: Foldable solar panels are made of waterproof, dustproof and corrosion-resistant materials and processes, allowing them to be used in a variety of harsh environments with a long life span. |
