We recently removed 2000w of flexible panels after the very telling 2 year warranty period had expired from this motorhome.
Rv with solar panels roof.
The lightest panel is the allpower sunpower panel which is also flexible.
You ll also need batteries a battery monitor and an inverter which changes the dc power stored in the batteries into ac power for your appliances.
I attached our panels to the roof using 3m 4941 vhb tape and sealed the mounts with dicor self leveling sealant.
The number of solar panels you need on your rv roof will also depend on how heavily you use the electricity you re generating.
In many cases the flexible panels even burn the roof.
This is a great option for mounting panels because you do not have to make any holes in your rv s roof eliminating the potential for leaks.

Chances are solar panels will fight for space with other hardware on your rv roof such as an antenna or air conditioner so plan wisely.
However generally speaking most rvers travel with between one and three 100 watt solar panels which can generate approximately 6 amps per peak sun hour on average or around 30 amp hours daily.
When you mount flexible panels directly to your roof you essentially make your roof black which makes your roof and your rv very hot.
A 400 watt starter kit suitable for the roof of a standard rv might consist of four solar panels with wiring and an attached controller.
