Carter, thanks for the comments.
As for the solar roof, I do not expect to run the boat on solar only. lthough it will work fine on sunny days on the many European inland waterways where there is a speed limit (3-4 knots). I have a Honda portable generator as a backup. And there are charging stations all over the place, so with a battery range of 50 miles I should be fine.
Are you worried about the pod not being watertight (seals)? Would a twin screw setup not be less efficient compared to a single pod with a large prop?

Cover every square inch you can find and then some with the highest efficiency solar cells you can find if you want to push that boat with solar energy. If you plan on making it a diesel hybrid with a token solar panel then you're fine�but if you really want to get around on the Sun, you'll need�a lot more solar panels.

Trailerable, easily maintained, minimum (air) draft, comfortable, ready for all seasons, safe at sea. She will be powered by a 10kW steerable pod, running on a 30kWh lithium battery pack and 2kWp solar panels. We are currently finishing the design, selecting the (Dutch) yard where she will be built, and finalizing the specifications with several suppliers. Hull number 1 will be ours, but I'd like to see whether there's a broader interest in this project, especially when prices of solar panels and batteries are coming down.
