What is Foldable Solar Panel? How Does Foldable Solar Panel Work?

Foldable Solar Panels

What is Foldable Solar Panel? Just as the name suggests, this is a solar panel that uses solar cells to convert solar energy into electrical energy, and it can be folded. Solar energy is a non-polluting and inexhaustible source of energy, therefore, in the face of the pollution and shortage of petrochemical energy, how to use solar energy sources effectively has become the focus of attention, and foldable solar panels are becoming more and more popular nowadays.

Why we make it folding? Everyone knows that most of the existing solar panels are coming with the fixed-planar structures, we usually install them out of doors or on the roof of the house. After installing the solar panels, they are basically fixed in position and cannot be disassembled, especially in the case of severe weather or relocating, the solar panels cannot be recycled in time, because it easily damages the solar panels and causes huge economic losses. So for the convenience of use, there are many foldable solar panels that are used in different applications on the market.

How to choose the right power Foldable Solar Panels?

Let us try to choose a solar panel to power a 6 watt device for 5 hours a day, we first do a math that the 6W device will consume 5 x 6 = 30 watts each day, so the solar panel will need to produce 30 watts per day. Let’s assume six hours of sunlight so the solar panel needs to generate 5W per hour, consider the loss of the solar power, so a 6 watt solar panel will do the job. There are many devices and many watts to choose from, here are some best sellers on the market.

For larger solar panels, you need a solar regulator or solar controller to control the current, or it will cause damage to your battery, the solar regulator will ensure the battery is not overcharged all you need is the sun to produce clean and free solar energy.

Foldable Solar Panel 12V

12 Volt solar panel is good for charging 6-9V devices, such as Lamps, LED Lights, etc.

18 Volt Foldable Solar Panel

18v solar panel is good for charging 12v lithium and lead-acid battery, such as laptops, tablets, etc.

5v Foldable Solar Panel

5 Volt solar panel is good for charging the device voltage less than 5v, such as smartphones, USB fans, flashlights, etc.

What is the Best Foldable Solar Panel for your application?

The best foldable solar panel must have the right power and right voltage that suitable for your application, voltages, and power are the most important features. For example, you cannot use a 5 watt 5 volt solar panel to charge 12v 10Ah battery. There are some applications as below:
