Large Solar Panels
I have been looking at maybe using 2 255 watt panels they are big 65"x 38", this would give me more wattage than using 4 100 watt. I know that I need more battery but you have to start somewhere. Any...

Any of the other RC pilots here that build their own should be able to explain lift too.
There is a difference between a flat mounted panel and the building. The building has a large face to create up slope. That face allows pressure to build up and create a natural airfoil.
On a long burm that up slope will let me toss a glider out and fly it back and forth as long as the battery hold out.
A flat mounted panel has a relatively small face and is off the deck allowing the pressure to not build up as much. It builds some because the airflow is less under the panel but it isn't the full effect that a building sees.
You can lay a piece of wood on the ground and blow enough air over it to lift it just enough to get the wind under it. That's when it takes off. It doesn't take a lot of lift to do that or a lot of support to keep it from happening. That's why we don't read a lot of reports of properly installed panels coming off.
