but if one day they produce the maximum then you will be in over voltageI believe there is a quantitative benefit to over panelling. Panels rarely produce their rated power and degrade over time. Higher DC to AC ratios mean that the inverter will be operating at optimum output more often. As mentioned earlier the amount lost to clipping is often a concern, but when calculated over time it is often very small.
