Different wattage panels on one solar controller

I may be in the position where I would like to add additional panels that are a different wattage and voltage to a single solar controller. I realize that I need to stay under 60 volts on a Delta 2 max series with the combined panel series input so that's not my question.

My question is, assuming all of the panels are modern N Type but have different voltages and wattages, for example, say I have one 100 watt panel with a VOC of 20.3 volts and a 175 watt panel with a VOC of 25.5, if I wire in series on same solar input, will may maximum wattage be 175 watts or 100 watts or 275 watts?
