Attaching Solar Panels to RV Roof Without Drilling: A Comprehensive Guide


You can attach solar panels to your RV roof without drilling by using adhesive mounts or heavy-duty velcro. These methods allow you to install the panels securely without causing any damage. However, you must ensure the roof surface is clean and the adhesive is suitable for the material of your RV roof.

Reasons to Mount RV Solar Panels Without Drilling

Mounting solar panels on your RV roof without drilling offers a number of benefits. First, it prevents you from damaging the structural integrity of your RV roof, thus avoids potential water leaks. Secondly, the absence of holes in your roof means there are fewer routes for heat to escape – an ideal scenario when winters roll around. Lastly, it provides flexibility – if at any point you decide you want to change the setup or remove the panels altogether, you can do so without leaving permanent scars on your RV roof.

Understanding Different Types of Solar Panels

It’s essential you understand the types of solar panels at your disposal before diving into their installation processes.

Rigid Solar Panel

Rigid solar panels, also known as fixed solar panels, are sturdy with a thick glass covering for protection against the elements.

Pros and Cons of Rigid Solar Panels

Rigid solar panels are highly efficient and have a long lifespan. However, they are heavier than their counterparts and require a more robust mounting structure.

Flexible Solar Panel

Flexible Solar Panel

Flexible solar panels are extremely lightweight and can be bent to fit the contour of your RV roof.

Pros and Cons of Flexible Solar Panels

Flexible solar panels are lighter, thus easier to manipulate and attach. However, they tend to have shorter life spans and can be less efficient than rigid ones.

Methods of Mounting Solar Panels on RV Roof Without Drilling

Solar Panel Corner Brackets

Corner-mount brackets are typically used for mounting rigid solar panels. They are secured to the edges of the panel and demand an adhesive to attach them to the roof.

Advantages of Using Corner Brackets

Apart from being easy to install, corner brackets minimize wind resistance by keeping panel edges flush against the roof, which is a major advantage when driving.

How to Install Solar Panels Using Corner Brackets

To install solar panels using corner brackets, spread a high-quality outdoor adhesive on the base of each bracket, position your panel, and press the bracket onto the surface. It’s essential that your roof is clean before installation.

VHB Tape

VHB Tape

VHB (Very High Bond) tape is a type of adhesive tape commonly used for mounting flexible panels.

Advantages of Using VHB Tape

The strength of VHB tape negates the need for any drilling. It also accommodates the flexible nature of these panels and allows them to conform to the RV’s roof shape.

How to Install Solar Panels Using VHB Tape

To install with VHB tape, you simply apply the tape to the rear surface of the panel, peel off the backing, and press it firmly onto the clean RV roof.

Using Portable Solar Panels

Portable solar panels, such as ‘suitcase’ panels or foldable ones, can simply be laid out on the roof or the ground.

Advantages of Portable Solar Panels

The primary benefit of using portable solar panels is the convenience factor. They can be packed away when not in use, reducing the likelihood of theft or damage.

Suitcase Solar Panels

Suitcase solar panels are two panels hinged together. They’re easy to handle and store.

Foldable Solar Panels

Foldable Solar Panels

Foldable or blanket-type solar panels can be folded or rolled up for easy storage.

How to Install Portable Solar Panels on RV Roof

Portable solar panels don’t necessarily need permanent attachment to the RV. Just ensure they’re secured to prevent wind from catching them, especially when driving or in stormy conditions.

Best Adhesive for No Drill Roof Mounted Panels

Choosing the right adhesive is crucial. While I have specifically mentioned VHB tape, Sikaflex 252 adhesive is also a strong contender. Providing a rigid and durable bond, Sikaflex withstands the harshest of weather conditions making it a solid choice.

Safety Considerations When Mounting Solar Panels Without Drilling

While mounting solar panels on RV roof without drilling sounds liberating, it’s important to keep your safety and the safety of your rig in mind.

Potential Dangers and How to Avoid Them

The RV roof can be slippery, especially in damp conditions. Always exercise caution when climbing up. When installing, make sure your RV is stable and level. Well-designed tools and installation kits – found on our Solar Panels for RV Installation page – can also help you avoid mishaps.


Attaching solar panels to your RV roof without drilling gives you the power to enjoy off-grid living or travel, without compromising your beloved vehicle’s integrity. Hopefully, you now feel equipped with the knowledge and confidence to take this solar leap. From scouting the right solar panel, choosing an ideal non-drilling method, to heeding safety considerations – it’s all a part of this grand solar journey. So here’s to illuminated adventures and greener travels!
