6 FAQs about [Are photovoltaic panels considered live load panels ]

Should PV panels be considered as dead load?

The latest ASCE version (2016) now requires the PV panels to be considered as dead load. This can cause major complication in determining the total system weight especially in high seismic regions. Also, live load should not be considered on the roof if the panels were placed at specific distances and heights.

Are solar panels required for a roof photovoltaic live load?

Solar photovoltaic panels or modules that are independent structures and do not have accessible/occupied space underneath are not required to accommodate a roof photovoltaic live load, provided the area under the structure is restricted to keep the public away.

Does a roof support solar photovoltaic panels or modules?

The structure of a roof that supports solar photovoltaic panels or modules shall be designed to accommodate the full solar photovoltaic panels or modules and ballast dead load, including concentrated loads from support frames in combination with the loads from Section CS507.1.1.1 (IBC 1607.13.5.1) and other applicable loads.

What conditions should a roof support a photovoltaic panel system?

Roof structures that support photovoltaic panel systems shall be designed to resist each of the following conditions: 1. Applicable uniform and concentrated roof loads with the photovoltaic panel system dead loads.

Can a roof deck support a photovoltaic panel system?

Structures with open grid framing and without a roof deck or sheathing supporting photovoltaic panel systems shall be designed to support the uniform and concentrated roof live loads specified in Section CS507.1.1.1 (IBC 1607.13.5.1), except that the uniform roof live load shall be permitted to be reduced to 12 psf (0.57 kN/m 2).

Are solar panels dead load?

Good luck! Solar panels are dead load. Perhaps the loading notes and drawings say that it is designed for particular loads, but you could carry out an assessment to see whether the roof is capable of taking the solar panels in addition to the design loads.
