Roof-Mounted Solar: Structural and Waterproofing

Flashing is the process of using roof-compatible, waterproof materials to keep water from penetrating a roof system at penetrations, joints, horizontal-to-vertical intersections and so forth. Generally speaking, effective flashing requires

About Waterproof requirements for photovoltaic support base

Understanding and addressing the fundamentals of solar panel structural requirements can help ensure the safe and effective operation of a solar energy system. Considering factors such as roof material, age, slope, bearing capacity, and local regulations can significantly contribute to a successful installation.

Consider the roof type (material and slope), weatherproofing, installation convenience, and wind and snow loadings. Choose an appropriate racking and mounting system for the type of PV module, and install the system along with needed flashing and seals. See the Compliance Tab for related codes and standards requirements, and criteria to meet .

For existing buildings, when installing PV module bases, the waterproofing layer should extend over the base and metal fasteners, with sealing around anchor bolts. Waterproof sealant should be applied where penetrations occur, and an additional waterproof layer under the base is recommended.

This blog will aim to answer several questions related to evaluating solar panel damage and liability claims such as whether the code has information on solar panel loading and requirements (spoiler alert – yes!) and when and where a design professional is recommended for solar panel installation projects (hint – always!).

6 FAQs about [Waterproof requirements for photovoltaic support base]

Does a solar mounting system need a waterproofing system?

A solar mounting system must be integrated with the existing roofing system to maintain its waterproofing integrity. This involves: Waterproofing: Ensuring that the mounting system does not compromise the roof’s ability to repel water.

What are solar photovoltaic design guidelines?

In addition to the IRC and IBC, the Structural Engineers Association of California (SEAOC) has published solar photovoltaic (PV) design guidelines, which provide specific recommendations for solar array installations on low-slope roofs 3.

What are the requirements for a solar panel installation?

Solar Panel Specifications: The size, weight, and configuration of the solar panels must be compatible with the mounting system to ensure a secure installation. Climatic Conditions: Environmental factors such as wind, snow, and seismic activity must be taken into account to ensure the system can withstand local conditions.

What are the structural requirements for solar panels?

Structural requirements for solar panels are crucial to ensure their durability, safety, and efficient performance. These requirements vary depending on the type of installation, such as rooftop or ground-mounted systems, as well as the specific location and environmental factors.

Can a PV substructure be adapted to a flat roof?

Of course, this also applies to our flat roof solutions, which enable a PV substructure optimally adapted to the respective flat roof for flat roofs with gravel, bitumen/foil as well as for green roofs. In addition, mounting systems for the PV substructure on façades as well as our in-roof system are also available to you.

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.
