Likely minimual power loss because it's small. If it is large enough to activate the bypass diode which most RV panels have then you lose the voltage for those cells.
For example iIn a 6x10 panel with 3 bypass diodes then you lose 1/3 the voltage. Two panels in series then yields 1 2/3 the voltage or power. Same panels in parallel yields 1/2 the power.
With 2x2 series/parallel panels an activated bypass diode reduces the series voltage of that pair resulting with 1/2 power, while parallel would have 3/4 power.
Regardless of the voltage and amps an MPPT controller optimizes the charging power.

What would the IV curve look like if one series panel looked like this?
Would controller algorithm 'pick' the correct mppt?
