Give two reasons why solar panels are almost never connected in series only.

1. The overall voltage may become too high, exceeding safe limits or the capacity of connected devices.
2. A failure or shading of one panel can significantly impact the performance of the entire series circuit.



Answer :

Final answer:

Solar panels are not connected in series only due to shading limitations and reduced performance.


Explanation:

Solar panels are almost never connected in series only due to the following reasons:

  1. Partial shading of a single cell limits the current the whole panel delivers, affecting the overall efficiency.
  2. Connecting panels in series creates vulnerability to partial shadowing, reducing the panel's performance.
