Hey everyone! I'm designing a custom boat for my company and want to incorporate a small electric engine to work alongside gas engines. I'm considering whether I can use solar panels as part of the roof to provide shelter for guests. Should I place the panels directly on the roof frame, or is it better to build a roof and then put the panels on top? The boat dimensions are 30ft in length and 10ft in width, and I'm thinking of a custom frame to hold the panels. I initially thought about using bifacial panels, but I've heard they might be too heavy and pose a risk with all that glass overhead on a moving vessel. Just for clarification, I can't charge off the outboards' alternators, I've looked into that already. Thanks in advance for your advice!

I’ve got some bifacial panels mounted on the ground, and it gets pretty hot behind them when the sun's out. I really wouldn’t recommend using them as a roof on a boat.
In my experience, it’s best to add a solid roof first and then attach the solar panels to that. Space on a boat is limited, and people generally prefer room to move around over solar power.
Remember, solar panels expand with heat. If they're too tightly packed, you'll run into problems. Also, keep in mind that panel sizes can change with each new model, which could complicate repairs down the road. Is this boat intended for long-term use?
Totally agree! The heat trapped underneath could really be a problem.
