What size of solar panel do I need to power a 20-foot launch?
I want to power an electric 20-foot launch by solar panel only, no battery banks.
How much solar panel wattage do I need to make about 8 knots?
Thanks.
The general rule is that, if you are going to power directly from a solar panel, the output of the panel should be 10 times the draw of the appliance. A motor that will drive a boat of that size will draw over 125 amps at 12v. So you will need 1250 amps of output .... a solar panel that is about 49" X 44" will output 9 amps of usable power at 12v. So, You will need at least 140 panels ... they cost around $700 each in quantity. Each panel is about 14 sq ft ... so you will need about 1960 sq ft of panels at a cost of nearly $10000. A 20 ft boat with a beam of 8 ft might have a 160 sq ft of canopy available ... Sooooo You will have quite an overhang on your solar array ..
