Really…10x?

Subject: [Electric Boats] Marine Solar Array makes 3 knots
We have just recently completed testing of our solar array which you can find on the website at
http://www.propulsionmarine.com/electric/charging-sources
SOLAR - The Propulsion Marine Solar Array Features:
2 x 225 watt Sanyo Panels for total of 450 watts at 90 Volts
Midnite Solar Charge Controller
Electric Actuator Lift Arm
Electric Worm Gear Chain Drive to Rotate Pole
Joystick Control
Tracker Expected to be released soon.
By Focusing on the sun, power developed is as high as 10 times more than if panels are mounted horizontally
Kapowai is capable of obtaining 3 knots while motoring under power made directly from the solar panel.
