A series-parallel connection is accomplished by using both a series and a parallel connection. Every time you group panels together in series, whether is 2, 4, 10, 100, etc. this is called a string. When doing a series-parallel connection, you are essentially paralleling 2 or more equal strings together.
Because the solar cells are in series, a drop in current in one or more cells will cause the current in the whole panel to drop. This is again where diodes can help us. If we now put a diode over each cell in the panel, then if one cell is shaded the total voltage will drop by 0.6V but the current from the other cells will still get through ...

Solar cells are the black squares that are all connected in series in one long string across the panel. If a single cell in a solar panel is shaded from any source, that cell will now produce less power. ...
Therein, the metal bonding interlayer can also act as an optical reflective mirror. Meanwhile, for multijunction solar cell applications, using a metal-bonding interlayer can cause substantial optical shadow loss for the subcells beneath the bonded interface, which would limit the overall multijunction cell current in series electrical connection.
This can be done up to the point where the number of bypass diodes in the module equals the number of solar cells. 17, 18 Alternatively, series and parallel interconnections in PV modules can be changed during operation to optimize the energy yield depending on the uniformity of the illumination, which is usually referred to as the ...
