You can''t think of panels as a voltage source like you can a battery. Their voltage and current and therefor power output fluctuates based on the load on the panel, how much sunlight it is exposed to, how evenly that sun is applied across the array (or singular panel for microinverters), and the panels temperature. MPPT (Maximum Power Point ...

Your panels will operate closer to 17.98±3% X2 when producing power. Higher temperatures will produce lower voltage. Cells naturally get pretty hot when in full sun, so I would actually be more concerned about dropping under 35V in hot, clear, and sunny conditions rather than cloudy. IMHO, get a 3rd panel.
