[Public-List] Solar panels

I am also interested in what folks have done for solar.  Our only charging
is off the engine and shore power.

I was thinking about mounting (4) 100W panels above the lazarette supported
by the bimini frame and stanchions down to the stern pulpit about 6 feet
off the deck. Two panels would be fixed mounted and two mounted on drawer
slides above the fixed panels allowing them to slide out revealing the
fixed panel below.   The idea is while sailing, motoring upwind or in the
slip, the drawer mounted panels will be retracted to reduce windage and
overall width.  When anchored or on a mooring the extra panels can be
extended to maximize output.  I have a cabin top mounted mainsheet so it
opens that area up quite a bit.
