I don't know what you mean by 'inside edges'. If you mean the lower surface is not smooth, I'd place a cover under the solar panel and then use some vents to allow cooling air to pass above the cover. If that is the case, I can suggest how you'd do this.
Hello, as I'm new I cannot post pictures or links.

Yes, it's the lower surface that is not smooth at the start but the problem is mostly at the end, it's an aluminium U profile that traps the flow.
Cover under the solar panel it's not a solution either, as I responded in the previous post, heat is a major factor that has to be taken in account.

Please have a look at the last picture I posted here:

As for the length, yes I understand, I also thought it should be longer.
The profiles are quite small (3cm height) what length would you suggest by experience ?
Keep in mind that they are vans and campers, it usually not go over 100kph for a very long time.
