Adding panels of different wattage to existing enphase install

I have a 6.7 kw grid tied system using 31 REC 215 watt panels (two strings of 15 & 16) with Enphase M215 micro-inverters. I see that the REC 215s are discontinued. Can I add (3) 235 or 240 watt panels to the existing strings making 17 inverters per string - the design maximum?

Comments

Yes, definitely, you can add any module that is compatible with the M215 inverter.

Thanks for your prompt response. Now, where can I purchase 3 panels? It seems that Greentech Renewables only sells them in larger lots.

I'll have to refer you to an account rep. - they will respond ASAP with some ideas.Thanks for the question.
