The main material of the 200W foldable solar panel is silicon wafers. Solar cells made of silicon are currently the most popular type of solar cells, and their conversion efficiency can reach 20% to 24%. Other materials used to manufacture 200W foldable solar panels include plastic, glass and aluminium alloy. Among them, plastic is used to make the outer shell of the solar panel, glass is used to protect the solar cell and increase the light transmittance, and aluminium alloy is used to make the metal frame and back plate of the solar panel.

In addition, the 200W foldable solar panel also requires some supporting materials, such as wires, junction boxes, etc. These materials can transmit current through a 200W foldable solar panel and power other devices.

The manufacturing process of a 200W foldable solar panel typically involves the following steps: First, the silicon wafers are cut to the appropriate size, and then a layer of semiconductor material, such as gallium arsenide or indium phosphide, is coated on the silicon wafers. This layer of semiconductor material can convert light energy into electrical energy. Next, a layer of metal electrodes is covered on the semiconductor material. This layer of metal electrodes can transfer electrical energy to the external circuit. Finally, package the 200W foldable solar panel to protect the solar cells and extend their service life.

The service life of a 200W foldable solar panel is approximately 30 years, but its power capacity may decrease by 20%. During use, the 200W foldable solar panel requires regular maintenance and cleaning to ensure its normal operation.

The manufacturing and use of 200W foldable solar panels require a large amount of silicon, which is an important resource. Therefore, the recycling and reuse of 200W foldable solar panels are of great significance. The 200W foldable solar panel can be recycled, including the separation and reuse of materials such as glass, aluminum alloy, plastic, and solar cells. It is of great significance to establish an appropriate recycling infrastructure for 200W foldable solar panels. The world is facing the problem of phasing out billions of 200W foldable solar panels, with a recycling value of up to 15 billion US dollars.

Overall, the main material of the 200W foldable solar panel is silicon wafers, and other materials include plastic, glass, aluminum alloy, wires, junction boxes, etc. The manufacturing and use of 200W foldable solar panels require a large amount of silicon. Therefore, the recycling and reuse of 200W foldable solar panels are of great significance.
