Imlaminated solar panel modules chop traditional cells (single crystal, polycrystal, Sunpower, etc.) and then link them by stacking each piece back and forth. The layout is normally horizontal or vertical (but SunPower has a patent for vertical arrangement of modules, and enterprises typically use horizontal arrangement). Lastly, the special conductive adhesive material is used to connect it in series/parallel, and then laminated packaging.
Imbricated components
Different from traditional solar panels, the welding between traditional solar panels and flexible solar cable is to weld the positive and negative electrodes of the solar cells through copper belts, and keep a spacing of 2-4mm between the cells (depending on the size of the panels). Imbricated solar panels don't have that, so imbricated solar panels have more power and more natural power than conventional solar panels for the same area. In other words, for the same amount of power, an imbricated solar panel will have a smaller area than a typical solar panel, but the area receiving direct sunlight will not be any smaller.
There are also traditional solar modules relative to imbricated components, the surface of the copper belt connection, metal copper belt a width of about 2-3mm, metal copper wire will occupy the front of the bright area of the cell. Secondly, there is a certain line loss of metal copper belt. There will be some obvious differences in appearance, which can be readily observed through the surface copper band.
Why aren't the imbricated components prevalent?
Although the compatibility of imlaminated modules is higher, it will still take several steps more than the traditional solar panel process, such as the coating of conductive adhesives and the layout of laminated cells, so the packaging cost will be slightly higher.
A second possibility is the issue of the patent itself.
