Solar Panel Mounting Structure System for Flat Roof.

An increasing number of PV systems are being installed in commercial and home applications across the world. While many of the available roof areas at the commercial facilities are considered flat, even flat roofs have a minimal slope to them.

Three main options when racking a PV array on a flat roof exist: attached, ballasted and a hybrid option that uses both ballast and structural attachments. The latter is often referred to as a minimally attached system. Each has its own advantages and disadvantages that need to be weighed against each other.
