If you were to add a dissimilar solar module with lower power and current values to an existing string comprised of the exact same modules with higher current and power values, what would the effect on the total power for the entire string be$?$

A$.$ No effect whatsoever

B$.$ Minor effects

C$.$ The power output for the string would be calculated on the higher power modules

D$.$ The current for the string would be based upon the lowest current module thus lowering the power output for the entire string creating wasted energy.
