With a series of drop-in and quarter-turn connections on a specialized module frame, Trinamount installs up to four times faster than conventional mounting systems. By drastically reducing the number of parts, cost of materials and installation time, Trinamount offers the optimal solution for flat rooftops. Racking solution for flat roof racking commercial and residential solar installations.

An increasing number of PV systems are being installed in commercial applications across the US. How to build the frame for your Module Rail . While many of the available roof areas at the commercial facilities are considered flat, even flat roofs have a minimal slope to them. Often a rise of 0.25 inch over a 12-inch run - referred to as a 1/4:12 pitch - is typical. So these are more properly thought of as low slope applications.

While low pitch roofs are very often a dream installation site for many solar integrators, they present a number of design and installation challenges: valleys and ridges for drainage, the drains themselves, vents, exhaust fans, rooftop units, curbs and parapets. All of these have to be taken into account during the design process. In this article I examine the design constraints and considerations for flat roof mounting techniques. I also outline commercially available racking solutions for a variety of roof structures.How to build the frame for ground mount .
