Solar Mounting Systems

Solar panel modules require a special way of attaching them to surfaces and holding them in place. They are not weldered, soldered or hammered as they contain delicate parts that would be destroyed in the process. A solar mounting system is a metal structure or parts that are used to secure solar panels to structures. Since majority of solar panels are manufactured to be installed on rooftops, solar mounting systems are metal parts that are used to secure solar panels to rooftops in most cases. They are often an integral part of the entire solar electricity system design for retrofitting onto rooftops.


Components of A Typical Solar Mount

As all racking systems perform the same function, and though they are not all the same, there are components typical to all mounting systems. These include:


1. Flashings

Flashings are a necessity because often times, mounting panels on the roof require that holes be drilled into the roof. Flashing are materials used to stop water from leaking through the holes drilled into the roof. Flashings are specially designed to serve this purpose. They are often made from a wide range of materials including rubber, aluminium, galvanized steel, etc. They also come in different designs.

2. Mounts and Clamps

Sometimes referred to as “feet”, often a bolt through the flashing and into the rafter, mounts are used to attach solar panels to the roof. Clamps are used to secure the solar panels to the rails.

3. Rails

Rails are often long aluminium tracks that are installed either vertically or horizontally on the plane of the roof to bear the weight of the panels. The clamps hold the rails to the mount and the panels themselves are clamped
