Solar Panel Specs for MPPT-- Issues
I had some "issues" come up this year with panel specs that may be of interest. Ideally, you can check the panel specs to see if their voltages will be a match for use with MPPT so as not to confus...

In series amps from panels need to be identical. I don't think there is a tolerance rule of thumb for series amps.
yup, my experience also. Although differences in Vmaxpower between panels may have some affect on overall performance.
However, the current from the panels will be identical, but the panels don't need to have the same Imax, the system will just default to the panel with the lowest current. I have two 80W and one 100W panel in series and it is basically a 240W system when in the series configuration.
