Weight won't matter much (you typically only accelerate it once, and the additional drag is small), it is just that the surface area is so small relative to what's needed that it just doesn't move the needle.

According to that person, weight does indeed matter.
Yes, the weight of the hull, which is immense. Compared to that some solar panels probably weigh about as much as the paint. It's still ship, not an aircraft.
Drag is huge for boats, especially in seas and oceans that have tides and currents. Far more than a car... that also have to continuously burn oil to keep their speed, even on freeways.

Solar panels are also made from aluminum frames or can be flexible in plastic sheets. The weight is negligible.
