How many basic mounting methods exist for PV installations?

• A. 1
• B. 2
• C. 3
• D. 5

Answer: (C)

At its heart, PV mounting is categorized by how and where the modules are attached to a supporting structure: roof-mounted, ground-mounted, and pole-mounted installations. Roof-mounted systems attach to an existing roof structure, using either flush mounting or tilted racks. They make use of the building as the primary support, but require attention to roof type, penetrations, wind loads, and weight distribution. Ground-mounted systems stand on the ground with racks fixed to foundations or ballast. They offer easier access for maintenance, more flexibility in tilt and spacing, and are common for larger arrays or areas with ample unobstructed space. Pole-mounted systems place modules on standalone poles, which can be set at various heights. This setup suits spaces where roof or ground mounting isn’t practical and is often used in remote sites or along roadways and parking areas. Other configurations exist as variations of these basic methods, but these three cover the primary ways PV arrays are mounted.
