Above the Waterline

These pictures illustrate a solar array built for Liz Clark who is currently in the South Pacific.  The array can rotate around both the horizontal and vertical axis enabling it to point at the sun and then fold up to reduce windage in stormy weather.   Additionally the array doubles as a davit for her outboard motor.

These two panels are made by Sanyo.   They each put out 55 volts and are wired in series to 110 volts DC.   I then pass them through an Outback MX 60 charge controller.   This charge controller has Maximum Power Point Technology which steps the voltage down.   It continuously searches for the voltage to run the solar panels at to provide the highest power generation.    MPPT charge controllers are up to 30 percent more efficient than shunt or Pulse Width Modulated Charge Controllers.
