Change solar panels

Hi, I have 2 x 180 W solar panels Victron SPM011802400 on my boat. They are now 8 years old and working fine. Due to increased use of electricity want to upgrade to 2 x 215 W Victron SPM042152400. that should give ~ 25% increase in output, I hope. I do not want to upgrade to larger panels due to space limitations. I have one charge controller for each panel, so in total two Victron 75/15.

Question: can i just simply swap panels, same with same, or my installation will have to be amended ?


thanks in advance for your response.
