2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric, 700 ah @24 volt AGM battery bank. Plenty of Baja Sea of Cortez sunshine.
The panels are not a match for parallel connection, Your 330W panels will be pulled down to the voltage of the 250V panels.Not "330w panels." Only one 330w panel.
The general rule is that if you want dissimilar panels to work in parallel, their Vmp voltages need to be within about 5% of each other. Similarly, to run dissimilar panels in series you need their Imp currents to be within about 5%. In your case the voltages are too far apart to run them in parallel, almost 20%. The lower voltage panels will drag down the voltage of the higher voltage panel.As @mike95490 said, running them in parallel isn't quite within 5%, but would probably be OK. The current through the string would be limited by the current of the lower Imp panels (the Boviet), which would limit the Suniva panel to 8.3A instead of 3.8A at Imp. This would make it a 311W panel instead of a 330W panel, but that isn't too bad.
As you may already know, you'll need to fuse/breaker each panel to avoid a short in one panel being fed by current from the other five.
What kind type and kind of charge controller will you use? What system voltage will you use?
