 To simplify the question, the rest of this post analyzes a PV system with a
 shade obstacle like a wind turbine tower, a telephone pole, or a chimney, that casts shade
 perpendicular to the strings. My analysis is in this Jupyter notebook on Google Colaboratory:

 A look at the module IV curves tells the rest of the story. The shaded module
 still has to carry the 5[A] of the string, but 2 bypass diodes are triggered

+because the 1-string example isn't limited by the voltage of parallel strings, so it's free to operate at the max power
+point, and the losses are lower. Recall in the 20-string example, the shaded string lost about 15%, but in the 1-string

 ## Conclusion
 I wish I could say, "that's all there is to it." But as my first blog post
 says, electrical mismatch in crystalline silicon is very counter-intuitive.
