Assume a string of 36 PV cells in a module exposed to sunlight as shown in the figure. Each PV cell has a current and voltage output of 2A and 0.5V respectively. Cell 36 is partially shaded due to a leaf, which causes the current of this cell to drop to 0.5A. What will be the output current of this string (in A)? Which cell(s) will dissipate the highest amount of heat? Assume that by-pass diodes are installed across every 3 cells of the string. What will the current through the string now (in A)?
