How many types of PV racking systems for roof-top solar panels?

As is known, the most common way to mount systems to first install brackets, the shape and size of which will vary with the PV racking sytem manufacturer, but which will look something like the L-mounts pictured below. In the case of tile, slate, and shingled roofs, this may require cutting precise holes in the roof material for the mounting brackets to protrude from, while on corrugated roofs, the brackets will Rails are then fitted onto the mounts, which have been spaced appropriately apart so that the panels can be fitted flush together, side by side on the same set of rails. This is the most typical system for small- to medium-sized arrays, although flush mounts which support individual panels may also be used if the array is only composed of one or two panels. If you need to adjust the tilt angle of your array because the tilt angle of the roof is less than ideal, it is possible to do this with a universal mount by increasing the height of the rail higher up on the roof.

This Sto solar PV racking system consists of: brackets, rails, and panels.
