Stacked tile technology is a technology in which cells are sliced and then welded into strings with a special conductive adhesive material. The cells are connected in a front-to-back stacked way,with no metal grid lines on the surface and no gaps between the cells, making full use of the available surface area of the module. This reduces the wire loss of traditional metal grid lines and greatly improves the conversion effi- ciency of the module.
Stacked Tile Layout
Each string is connected in parallel so that shadows or dirt do not partially affect the output voltage of the entire panel.
Conventional Layout
If the surface is partially shaded If the surface is partially shaded lose the voltage of the affected part
