My setup is 6 x 1 panels across the back 6 meters by 1 meter
Steve450 iset up is 3 x 2 across the back 4.5 meters x 2 meters
Steves set up I believe is superior to mine although extending an extra 500mm aft it is 1.5 meters narrower and just looks more in keeping with the lines of the boat
. I also believe it suffers from less boom shadows than mine because you can move boom shadow off the panels easier because of the 1.5 narrower set up.
The Panels across the back provide very useful sun and rain protection for the rear cockpit
area. As well as a 130 plus amp battery charger
It provide somewhere to hang the fishing
rods under and a sun blind off, that can drop down when required. On anchor
we use the blind at least once every day to block the sun.
When designing your solar
structure think about a way to lift Dinghy outboard
on board if and when required, lot easier and cheaper to do two or more jobs with the same structure.
Make sure you give the panels a slight fall to the back to clear rain and keep it off the coach roof. Something I did not do and regret it every time it rains.
This will also aid in keeping the panels clean a small amount of dust can have a surprising detrimental effect on there output.
May even be worth while to incorporate a small gutter with hose attachment to facilitate rain collection. Water
is OK but it is dead water that you pay to make one way or the other. Free from the sky water that is also good for the herb garden as well as you is a win win.
