Solar Mounting Design Document

Why do you need a solar mounting system?

The right solar mounting system, if installed correctly, will provide the structural support a solar system needs, in order to protect it from wind-induced failure and other potential weather hazards. A mounting system can also set the orientation and elevation of a solar system, in order to maximise its energy performance.

What documents should be included in a solar roof plan?

At a minimum, these documents must include specific documentation of dead loads, live loads, wind loads, and, where applicable, snow loads for the existing roof design. These plans will provide important information for the solar designer when the homeowner decides to install a system.

What is a ground-mounted solar system?

Ground-mounted systems are often used for medium- to large-scale solar systems, are occasionally used in smaller systems – such as off-grid projects, or projects where roof space is not suitable. Post-mounted (used most often for smaller systems). All ground-mounted solar systems have to comply with AS 1170.2.

What are the different types of PV mounting systems?

Usually made from stainless steel or aluminium, most mounting systems are designed for universal application, and can come in a variety of styles including tilt frame, flat roof-mounted or ground-mounted. They can be customised to meet the size and specifications of a PV installation, as well as the style of roof or installation.

Can a roof support a solar system?

Structural or building engineers will need to ascertain if the roof can support the proposed solar system, and experts may conduct a structural and seismic analysis of the final design. Some mounting systems, such as the one ADB used, come with wind-deflecting components that reduce this force.

Where can solar panels be mounted?

Arrays are most commonly mounted on roofs or on steel poles set in concrete. In certain applications, they may be mounted at ground level or on building walls. Solar modules can also be mounted to serve as part or all of a shade structure such as a patio cover.
