Do solar panels need roof reinforcements?

Roof reinforcements may be necessary for some installations, depending on factors such as the roof's strength, the weight of the solar system, and local building code requirements. A structural engineer can evaluate the roof's condition and determine whether reinforcements are needed to support the additional load of the solar panels.

Can PV panels be installed on a new roof?

For example, some jurisdictions in CA and CO now require PV panels to be installed on certain new roof structures. The primary code used by structural engineers in the determination of applicable loads on buildings is ASCE 7: Minimum Design Loads for Buildings and Other Structures which is adopted by reference in the IRC and IBC.

How to install solar panels on a roof?

The foremost requirement is the structural strength of the roof, which should be capable of supporting the additional weight of the solar panels and the mounting structure. The solar panel mounting structure is usually made of mild steel or aluminum, which adds minimal weight but provides adequate support to the panels 1.

Where are solar panels located?

Usually, solar panels of a self-consumption system are located on the roof, although it is not the area closest to the storage system or energy meters. For security and architectural integration reasons, the roof of the buildings is usually determined as the location area for the solar panels.

How do I choose the right structure for photovoltaic panels?

When it comes to choosing the right structure for photovoltaic panels, several factors must be carefully considered. Geographic location are critical aspects to take into account. There are different types of structures to adapt to various surfaces, such as metal roofs, tile roofs, elevated or ground installations, and even wall-mounted structures.

Do you know the code requirements for a PV panel installation?

Frequently, the owner, contractor, or developer does not fully understand the code requirements to ensure the existing structural framing is not compromised by the PV panel installation. Depending on the jurisdiction and current code edition adopted, there may not be specific structural code requirements currently listed.
