Learn how to install Boulder solar panels using Boulder Mounting Brackets. Step-by-step guide for vehicle roofs and non-inhabited buildings, with tips to avoid common mistakes.

Quick answer

Use Boulder Mounting Brackets (4 Pack) to securely fasten Boulder 50 or 100 Solar Panels to a vehicle roof or non-inhabited building. The kit includes four brackets and all necessary hardware.

When to use these brackets

Boulder Mounting Brackets are designed specifically for Boulder 50 and Boulder 100 Solar Panels. They work best on flat or slightly curved surfaces like vehicle roofs, sheds, or garages. Avoid using them on inhabited buildings where roof penetration and waterproofing are required—these brackets are not sealed and may leak.

Tools you will need

You need a drill, appropriate drill bits for your mounting surface (metal or wood), a screwdriver or socket wrench, a level, and a pencil or marker. The brackets come with hardware, but you may need additional sealant for outdoor installations.

Step-by-step installation

Plan the bracket layout: Place the solar panel face-down on a clean surface. Position the four brackets at the corners of the panel frame. Mark the mounting holes on your roof or building surface using the bracket as a template. Common mistake: drilling holes without the panel in place can lead to misalignment. Always dry-fit first.
Drill pilot holes: Use a drill bit slightly smaller than the screws included in the kit. Drill through your marked points on the mounting surface. For metal roofs, use a sharp bit and go slowly to avoid slipping. Checkpoint: on thin metal, use a backing plate or large washer to prevent the screw from pulling through.
Attach the brackets: Align each bracket over its pilot hole and fasten securely with the provided screws. Use a level to ensure all brackets are even. Tighten until snug—do not over-torque, which could strip the threads or crack the surface. Common mistake: overtightening can damage the bracket threads. Hand-tighten and then give a quarter turn with a wrench.
Mount the solar panel: Lift the panel onto the installed brackets. Slide the panel frame into the bracket slots. Secure the panel using the locking hardware (clips or bolts) included in the kit. Double-check that all four corners are locked in place. Checkpoint: if the panel does not sit flush, the brackets may be misaligned. Loosen, adjust, and retighten.
Weatherproof the installation: Apply a bead of outdoor silicone sealant around each bracket base where it meets the roof surface. This prevents water from seeping under the brackets. Let the sealant cure according to the manufacturer's instructions before exposing the panel to rain. Common mistake: skipping sealant leads to leaks. Even on vehicle roofs, sealant protects against moisture damage.
