The shingle solar panel module slices traditional solar cells (single crystal, polycrystalline, solar energy, etc.). ), and then connect the small batteries in a way of front and back lamination. Typesetting is generally horizontal or vertical (but Sunpower module is patented as vertical, and enterprises generally use horizontal). Finally, series/parallel connection with special conductive adhesive is used, and then laminated and packaged. Different from the traditional solar panels, the traditional welding of solar panels is to weld the anode and cathode of solar panels together through copper strips, and the spacing between the panels should be kept at 2-4mm (depending on the size of the panels). However, shingle solar panels do not have these components, so under the same area, shingle solar panels will have more power and generate more natural electricity than traditional solar panels. In other words, under the same power, the area of shingle solar panels will be smaller than that of traditional solar panels, but the area receiving direct sunlight will not be smaller.
Single crystal conversion efficiency is high and expensive; Polycrystalline conversion efficiency is low and cheap.
There are many polycrystals in the domestic market, or they are all polycrystals.
The speed of polycrystalline silicon solar panels is generally two to three times that of monocrystalline silicon, and the voltage is more stable. 4. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, and the photoelectric conversion efficiency is about 12%, which is slightly lower than that of monocrystalline silicon solar cells. However, the material manufacturing is simple, power consumption is saved and the total production cost is low, so it has been greatly developed.
