Highest rated panel is the renogy 100 watt solar panel
Super strong panel that is safe to mount on the roof of a moving vehicle. I do not recommend larger panels! They are weaker. If you use glass panels, 100 watts should be the largest size you use.

In recent times, a good number of glass solar panels have hit the market with the same quality and durability ratings as the renogy panel above, but are made in china. Keep in mind that Renogy solar panels are made in the united states, which increases their cost. If you are on a budget, you may want to check out these panels instead:
Flexible Solar Panels
Lighter, easier and safer to mount on a vehicle and more aerodynamic than glass solar panels. These are new to the market, and people love them. Flexible solar panels cost only slightly more than solid glass solar panels.
100 Watt Flexible Solar Panel- Allpowers mono panel. Many flexible panels are having overheating/durability issues. This panel is the best one available right now.
These can technically be flush mounted but it is always best to find a way to allow for air flow under the panel.
Flexible panels run hot and do not last as long as glass panels, so try to keep them cool.
