different size panels

Just getting going again with 4 Sharp 165s I might add 4 205 s
to the 48v system. Will they diminish their potential adverging out with the 165s?
The 4 165s ,2 seried, two sets parellel, with the 205s wired the same way. Apollo to 16 6v Golf batts 8 series in parellel with the other 8. Batteries need to be replaced as they are 6 1/2 yrs old and struggling. Minimal loads at this time but need to grow. Thanx,,,

    As long as the Vmp of all your strings add up (close) to the same number (i.e., Vmp=62.x volts or some similar value)--then paralleling the different brands/wattage panels strings together will work just fine.
