*2.5. Diagonal Shading*

For diagonal shading M4, M7, M10, and M13 are shaded, as shown in Figure 7e. In diagonal shading, one module gets shaded from each row and column of a 4 × 4 PV array for all configuration schemes.

**Figure 7.** Shading pattern designs for PV array configuration schemes: (**a**) one module, (**b**) short wide, (**c**) long narrow, (**d**) central, and (**e**) diagonal.
