How To Install Solar Panels On Your RV?

A successful installation starts with a perfectly clean surface.

- Thoroughly clean the designated roof area, removing all dirt, grime, and old sealant.

- For a final, grease-free finish, wipe the area down with a degreaser like methylated spirits or isopropyl alcohol.

- Lay the solar panel on a flat surface and position the brackets to mark their precise locations on the frame.

This step creates a single, manageable assembly.

- Drill holes at the marked locations on the solar panel frame.

- For a superior, lasting bond, apply a polymer sealant or high-strength adhesive to the underside of each bracket.

- Secure the brackets to the frame using the provided bolts, screws, or pop rivets.

This is the most critical step for ensuring a permanent and waterproof fit.

- Apply a generous amount of a proven, UV-resistant adhesive like Sikaflex 252 to the underside of the brackets. Using a primer, as the manufacturer recommends, will enhance adhesion.

- Carefully position the entire panel assembly on the roof, checking its alignment.

- For framed panels, it is highly recommended to supplement the adhesive by drilling pilot holes and securing the brackets with screws or rivets. Be sure to create a waterproof seal around these penetrations with the adhesive.

- Pro Tip: Distribute the weight evenly to avoid putting pressure on any single point, which is especially important for older caravans.

With the panel securely in place, you can complete the system.

- Route the cables from the panel to your charge controller, using a cable gland for a clean and weatherproof entry point into the caravan.

- Connect the wires to the charge controller, double-checking that the positive and negative terminals are matched correctly.

- Finally, connect the charge controller to your caravan battery.

- For Inverter Users: If adding an inverter, connect it to the battery with appropriately sized cables and install the correct fuse in the circuit for safety.
