- Structural Review, Plans and Calculations
Structural Review Required
Structural review is required for the installation of PV systems where any of the following conditions occur:
- Alterations to a structure as required for support and/or attachment for PV systems.
- The weight of the PV system exceeds six pounds per square foot.
- The weight of any ground-mounted or roof-mounted equipment exceeds 400 pounds.
- PV mounting height, at any point, is greater than 24 inches above the roof level
- PV system installed on a ballasted roof.
- Ground-mounted PV system located more than five feet above the ground.
- Batteries not installed in accordance with the manufacturer’s instructions.
Provide the following information when structural review is required.
- Structural plans that demonstrate the required load path to the ground.
- A roof framing plan with the following information:
- Size and location of all roof framing members and vertical support elements.
- PV support structure framing plan with size and location of all framing members.
- Location, size and weight of any existing or new roof-mounted equipment.
- Maximum weight, number and location of PV panels.
- Size, weight and number of ballasts at each location.
- Attachment of panels to the support structure and the support structure to the roof or to the ground.
- Manufacturer’s installation specifications for pre-manufactured racking systems.
- Cross-section showing the height of the proposed PV panels above the roof or ground, the supporting structure, slope, and the distance down the slope from any roof ridge.
Structural calculations must be provided to evaluate the existing roof framing system for roof dead load, PV dead load (panels, ballasts, support platform, etc.) and roof design live load. For roof areas covered by the PV panels, where the clear space between the PV panels and the rooftop is 24 inches or less, roof design live load may be ignored. The adequacy of the following must be evaluated by a California-licensed civil/structural engineer or architect:
Existing gravity load-carrying structural elements (joists, beams, girders, trusses, columns, foundation) where installation of the PV system causes an increase in design gravity load of more than 5% and,
Existing lateral load-carrying structural elements (horizontal diaphragms, shear walls, braced/moment frames) where installation of PV system causes an increase in the demand to capacity ratio under earthquake loading of more than 10%.
A zoning review is required for the installation of PV systems that require a Building Permit or Combination Permit. Zoning, structure height, brush management, FAA notification and conditions of prior development permits are enforced for the installation of PV systems.
Historic review is required for the installation of PV systems that also require a Building Permit or Combination Permit if the project involves any parcel with a designated historical resource or is located within the boundaries of an adopted historic district, a historical review is required. Please refer to Information Bulletin 581, “Designated Historical Resource Review” for additional Historic Review information.
