Product Description

Shingled cells are made by dividing a full-size cell into five strips with each section being one fifth the size of a full cell. The narrow cell strips are assembled into long strings of 34 to 40 cells depending on the panel size. This results in a similar string voltage of a regular panel but a fifth of the electrical current. Lowering the string current reduces the resistance and operating temperature which reduces the chance of hot spots forming if there is ever a faulty cell or micro-crack.

Shingled solar cell

Unlike traditional solar panels which use soldered ribbons to interconnect the cells, shingled cell panels instead use electrically conductive adhesive (ECA) which reduces stress on the cells during manufacture. Additionally, as panels heat up and expand slightly during the day traditional solder ribbon expands and can eventually fail while the conductive adhesive used on shingled cells helps reduce the internal stresses due to thermal expansion.

Another benefit of using the shingled cell format where the strings of cells are assembled horizontally across the panel is the improved shade tolerance. Since each string of cells is essentially independent, if one or more strings are shaded it does not reduce the current of the other strings.

Shingled cells in strings are able to operate independently and perform very well under partially shaded conditions
