Flexible solar panels are an emerging technology product in the global solar industry. These are solar panels made from amorphous silicon encapsulated in resin as the main photovoltaic element layer laid flat on a base plate made of flexible materials. Features: foldable and foldable, easy to carry. But the conversion efficiency is slightly lower than ordinary rigid solar panels.
How many watts of homemade folding solar case is suitable?
Crystalline silicon solar cells are not foldable because the silicon material is very thin and brittle and must be encapsulated in glass, so it is heavy. It is thick and difficult to carry. However, crystalline silicon solar cells will soon be replaced by thin-film solar cells in terms of conversion efficiency and property characteristics,because thin film solar cells are amorphous silicon solar cells. For example, Zhongyi Industrial Copper Indium Gallium Selenide thin film solar cells. Cells use various elements. Attached to a stainless steel film substrate or plastic substrate by co-evaporation or spraying, the entire solar cell can be folded. Zhongyi Xingye gallium arsenide thin film solar cells can even be cut to suitable length and customized. Now, solar panels can be thin, light and foldable, but folding the entire battery is not possible because it would damage the internal structure of the panel. I believe that with the development of thin film solar cell technology this will be possible. in the future. .
The foldable solar package made by yourself is suitable for 5W to 20W. The power of the battery board can be selected between 5V, 5W and 20 W. The minimum configuration is to configure a battery card of 5 W or more. You can also configure 10W or 20W battery board, and the charging current will be higher. The solar foldable bag converts solar energy into electrical energy via solar panels to charge digital products. It has the advantages of being foldable and portable. The foldable bag has considerable advantages in terms of weight and size.
