The Off-Grid Systems

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.)  
Wind Turbine is a Whisper 200.  This unit replaced our original Whisper 1000.    Output is 1 kW peak.  
Daily kWhr’s varies.  The true value of adding Wind to a PV system here in WI is the bonus energy derived during Winter.  This small genny is often providing a mere  .25 kW.  However, the wind doesn’t “set”, meaning this .25 kW can still create 6 kWhr’s over 24 hrs on a moderate wind and substantially more amidst high winds.  
Not Shown:  Our remote acreage utilizes an off-grid array for PV-direct water pumping.  It consists of (2) SW325’s powering a Grundfos Flex pump.

 Note:  This payback analysis is based on 2010 costs which have since dropped substantially.
