So if I understand this (searched and read)......

I have a couple of Kyocera 135 watt 17.7Vmp 7.63Imp panels in parallel.

I can add 2 additional Sun 190 watt 17.4 Vmp 10.92 Imp panels in parallel with the existing Kyocera Panels?

    Should not be a problem in parallel. Just be sure all panels are properly fused.

    The voltages are close enough that it should not be a problem, but can your charge controller/inverter, wiring, and OCP handle the current? Imp = 2(7.63) + 2(10.92) = 37.1A, and max Isc is a bit higher, of course.

    Wiring / fuses is all good. Xantrex 35 amp controller :) Living on the edge.
    Actually I have not seen the Kyoceras put out anything north of 11 amps in cool weather with direct sun.
    I aint skeered.
