The solar panel is comprised of either 18 or 36 strings, where each string contains 18 solar cells. For 18 strings of solar cells, each cell is 10cm wide and the height of each cell is 5cm. On the other hand, for 36 strings of solar cells, the width of each cell is reduced from 10cm to 5cm and the height of each cell remains 5cm.

Homogenous Voltage-Matched Strings Using Three-Terminal Tandem Solar
Strings constructed from three-terminal tandem (3TT) solar cells offer the performance benefits of voltage-matching (which reduces sensitivity to spectral variation), but without the subcell voltage isolation required by four-terminal cells. However, the circuitry for a 3TT string can become complex, making circuit analysis more challenging. Here, we illustrate

Difference between String and Array in Solar Panels
A solar panel or PV module is made up of several cells, while multiple solar panels wired in a series or parallel is called a solar array. A string consists of solar panels wired in a series set into one input on a solar string inverter. If you have two or more solar panels wired together, that is a solar / PV array.

Low-breakdown-voltage solar cells for shading-tolerant
However, strings of solar cells perform poorly under non-uniform illumination. One of the main factors that affects the shading tolerance of a PV module is the reverse current-voltage (I-V) characteristics of its solar cells. Most crystalline Si solar cells have a breakdown voltage (BDV) between −10 and −30 V. 6, 7, 8
