On a solar ship - you generate 4MW of solar power from panels at 20% efficiency - using the surface area of the largest container ship.
4000kW. $400/kw. 1.6M for the panel.
Cargo ship uses 16 tons of fuel per hour. Fuel cost is $300/ton. $38M/year in fuel.
About 8000 hours per year. 16x300x8000=$38M
1 container ship creates as much pollution as 50M cars.
A typical ship has a 9 MW power use.
With telescoping panels, solar can match industry standards.
Night time power - could be addressed via solar hydrogen production.
