  • Patent number: 8661748
    Abstract: A light weight ballasted solar racking system has light ballasted weight loads and is easy and fast to install. The racking system may be used in roof or ground mount applications to mount thin film and frameless solar modules. The racking system physically attaches to the solar panel at the manufactured mounting holes with a set of struts that then attach to a ballast tray that holds the system in place. A set of struts may determine the degree of angle from about 5 to about 35 degrees, for example. The front of the ballast tray has an air pass way of about 3-5 inches, while the back of the system has about 8-12 inches of space for an air pass way. Multiple racking systems may be linked together, resulting in the need for less ballast weight for each racking system.

  • Publication number: 20130192587
    Abstract: A solar ballasted racking system holds hot water flat plate solar collectors in place on flat roofs without penetrating the roof surface. The racking system also holds the collector in place, providing a stable, long-term placement on the roof while protecting the roof surface with foam pads placed under the ballast tray. The ballast tray is built in two sections—one to hold the solar collector in place and a second to act as a wind deflector that deflects the wind off the solar collector. Ballast blocks are added into the ballast tray to hold the collector in place. The racking system may enhance the life of the roof while protecting the roof surface and allowing for lower ballasted weights due to the wind deflector.
