Replacing 100W panel with a new Renogy flexible 100W panel.

I currently have a 150W panel and 100W panel, both from the same manufacturer. They have similar specs and have been wired in parallel. I have been told that it is best to have panels with the same voltage output when wiring together. I am charging 2 12v AGM batteries in my camper. By going to the Renogy 100W panel will introduce a slightly different spec panel. What issues will i have?
