NOTE: THIS LISTING IS FOR JUST ONE WALL BRACKET ATTACHMENT. YOU WILL NEED TO ADD TWO OF THESE TO THE CART AND 2 Regular Kinetic Solar (Rapid-One) rails to mount two solar panels. For greater numbers of solar panels you will need to add enough wall brackets and additional rails to account for the full width of the entire row of solar panels you wish to install.
Canadian-made Kinetic Solar Wall/Awning Mount, type KWN60P-G, makes it easy to mount solar panels to a wall. These are galvanized steel brackets that are fastened to a wall. Regular Kinetic Solar (Rapid-One) rail is mounted on the brackets, and panels go on top of that using regular mid- and end-clamps. The brackets work for both 60- and 72-cell panels, and the panels mount in portrait at a 60-degree tilt-angle (to the horizontal, so the angle with the wall is 30 degrees).
For Rapid-One rail one bracket is needed every 4 feet, with a maximum cantilever at the ends of 19″. the KWN60P-G brackets come as a single unit, with a set of 2″ L-brackets. The hardware to mount to the wall, or rails and other panel mounting hardware is not included. To mount a single panel you would need two KWN60P-G brackets, and for more panels they would simply be spaced every 4 feet (just like regular L-brackets on a roof solar installation).
