Types of Photovoltaic Solar Mounting Systems – 5 Common Mounting Systems
Ground Mount Systems. Ground mounts use a framing system similar in design and orientation to standard passive slanted roof mounting systems, except they are mounted on the ground adjacent to the building or source of consumption. These systems are used when the desired electrical output of the system is limited due to a lack of roof mounting area or simple because of aesthetics. Soil testing and the use of the appropriate anchoring system for the environmental characteristics of the site are necessary.
Building Integrated Photovoltaics (BIPV) - These architecturally pleasing mounting systems occupy a large market for new, innovative design in photovoltaic mounting. These systems can be installed on many building surfaces including vertical walls and atriums similar to glazing systems used in the skylight industry. Wiring is run through interior walls or the support structure with the associated equipment stored in equipment rooms or basements. Some advantages of building integrated mounting systems are:
Mounting systems that can be customized to blend into building architecture
Dual benefits of generated solar power & shading, cooling or protection from the elements
More esthetically pleasing and versatile than conventional solar mounting systems
Photovoltaic Solar Canopy, Walkway & Awning Systems – These mounting systems are unique in that each application has its own architectural design, load and secondary use characteristics. Like building integrated photovoltaics, semi-transparent panels are often used and mounted using a process similar to glazing systems used in skylight construction. All the internal wiring is contained within the structural mounting system. In applications where the structure is stand-alone, the balance of the wiring can be run underground or through conduit, while the associated electrical components are housed in the adjacent building.
Pole Mounted Systems. Pole mounts are essentially ground mounts without the framing system. Solar arrays are attached to the top or side of the mounting pole. These types of mounts can allow for manual or mechanical adjustment of the panel orientation for seasonal tracking of the panels to the overhead sunlight path.
Roof Mounting Systems. Slanted roof mounting systems are the most commonly seen portrayals of mounted solar panels. Both affordable and fairly easy to install, there are other advantages to roof mounting systems. They include:
Protection from vandalism, unwanted & accidental contact
Wide variety of substrate attachment options
Height may make the system less affected by shading & obstructions
Can be customized for a specific application
These framing systems are generally comprised of aluminum, stainless steel for additional strength and anti-corrosion or a combination of both.
