In one embodiment, an apparatus is provided. The apparatus includes a first rail coupled to a second rail, a third rail coupled to the second rail, and a fourth rail coupled to the first rail and the third rail. The apparatus may form a rectangular frame from the four rails. The rails may be coupled through use of corner connectors or may be mitered and coupled through use of brackets in an abutting relationship. Additionally, further rails may be added by interposing the additional rails between a pair of the first, second, third and fourth rails, to extend the frame, and such additions may involve connectors or abutting rails and brackets, for example. The rails may have support ledges. Alternatively, the rails may have slots allowing for support brackets which slide along the slots. Moreover, the rails may be anchored using roof anchoring components to various surfaces. Additionally, the rails may support photovoltaic or other solar panels, and may have caps or top brackets to maintain the position of such solar panels. In another embodiment, a method is provided. The method includes reviewing solar days of a site. The method further includes reviewing geographical features of the site. Also, the method includes estimating a guarantee of available solar energy for the site. Moreover, the method includes installing a solar system at the site. |
