The array below is actually two separate arrays.  
        On the right:  6 Solarworld  SW255’s - 1.5 kW
        On the left:    6 Solarworld  SW 325’s  -  2.0 kW
        The 255’s feed a Xantrex  XW 60-150 MPPT Contoller
        The 325’s feed a Midnite Solar Classic 200 MPPT Controller
        These are connected to a 24vdc battery bank feeding a trusty 1996 Trace SW4024 inverter.   Combined, these arrays will produce 20 kWhr’s on sunny days.   (These arrays replaced our  original Quad Lam s.  The Quads still work.  However we’re now producing over twice as much power on the same footprint.)
