Solar panel advice

[Nuii]

Need advice on additional solar panels to be added to my existing setup.

Currently I got a 2 x Growatt SPF 5000 ES inverter and 10 x fivestar 650w sola panels and now looking to add 4+ more panels. Unfortunately I couldn't find the same solar panels, is mixing solar panels a good idea if the voltages and amps are more or less the same?
Below are the panel specs for standard test conditions. Not sure which brands are good.
Prices for the panels are more or less the same.

	Fivestar Mono (What I have now)	BYD 550 Mono Solar Panel	Jinko 550w	Seraphim 560W mono	Seraphim 555W Bifacial
Nominal Maximum power(PMax)	650W	550W	550W	560W	555W (Front) 389W (Back)
Optimum Operating Voltage (Vmp)	51.2V	42.49V	40.90V	42.56V	42.1V (Front) 42.34V (Back)
Optimum Operating current (Imp)	12.69A	12.94A	13.45A	13.16A	13.12A (Front) 9.19A (Back)
Open circuit voltage (Voc)	60.92V	50.32V	49.62V	49.90V	49.80V (Front) 49.78V (Back)(
Short circuit current (Isc)	13.58A	13.61A	14.03A	14.21A	14.1A (front) 9.94A (Back)

Look at some 325W panels and see if you can’t 2S some to ‘match’ your 650’s more closely.

On the other hand, you could buy whatever you want along with an appropriate Epever or Victron or Ampinvt SCC and just plumb them in to the battery bank directly.
