Panels lose efficiency every year, from the day they were made. At the rate less than 1% a year.
Drop 0.3V after controller? Possibly. Depends on what cable and how long.
With more solar wattage he will have to replace the controller anyway. Morningstar MPPT 45 has terminals for voltage sensing wire, they call it "battery sensing". This is a thin wire that carries no power, to ensure correct voltage reading on the controller unit. It still shouldn't be too long - I think 20ft max.
I am against reading too much data, this is why I tucked my display in a corner where I won't see it often :)...
But, controller should be set up properly first. For some people monitoring amp-hours is a good idea, too. $25 on Ebay.
