It's a system of engineered components that can be assembled This manual provides(1)supporting documentation for into a wide variety of PV mounting structures.With building permit applications relating to Unirac's SolarMount SolarMount you'll be able to solve virtually any PV module Universal PV Module Mounting system,and(2)planning and mounting challenge. assembly instructions for SolarMount It's also a system of technical support:complete installation SolarMount products,when installed in accordance with and code compliance documentation,an on-line SolarMount this bulletin,will be structurally adequate and will meet Estimator,person-to-person customer service,and design the structural requirements of the IBC 2009,ASCE 7-05 assistance to help you solve the toughest challenges. and California Building Code 2010(collectively referred to This is why SolarMount is PV's most widely used mounting as"the Code").Unirac also provides a limited warranty on system. SolarMount products(page 26). I 1 AThe installer is solely responsible for: • Complying with all applicable local or national building codes, including any that may supersede this manual; • Ensuring that Unirac and other products are appropriate for the particular installation and the installation environment; • Ensuring that the roof, its rafters, connections, and other structural support members can support the array under all code level loading conditions (this total building assembly is referred to as the building structure); • Using only Unirac parts and installer-supplied parts as specified by Unirac (substitution of parts may void the warranty and invalidate the letters of certification in all Unirac publications); • Ensuring that lag screws have adequate pullout strength and shear capacities as installed; • Verifying the strength of any alternate mounting used in lieu of the lag screws; • Maintaining the waterproof integrity of the roof, including selection of appropriate flashing; • Ensuring safe installation of all electrical aspects of the PV array; • Ensuring correct and appropriate design parameters are used in determining the design loading used for design of the specific installation. Parameters, such as snow loading,wind speed, exposure and topographic factor should be confirmed with the local building official or a licensed professional engineer. ge ` 2 �// 0 SolarMount Unirac Code-Compliant Installation Manual :: U N I RAC Part I. Procedure to Determine the Design Wind Load [1.1.] Using the Simplified Method - ASCE 7-05 The procedure to determine Design Wind Load is specified for more clarification on the use of Method I. Lower design by the American Society of Civil Engineers and referenced in wind loads may be obtained by applying Method II from ASCE the International Building Code 2009. For purposes of this 7-05. Consult with a licensed engineer if you want to use document, the values, equations and procedures used in this Method II procedures. document reference ASCE 7-05, Minimum Design Loads for The equation for determining the Design Wind Load for Buildings and Other Structures. Please refer to ASCE 7-05 if components and cladding is: you have any questions about the definitions or procedures presented in this manual. Unirac uses Method 1, the s �ll�zfl Simplified Method, for calculating the Design Wind Load for Pnet(p f) = pnet30 pressures on components and cladding in this document. n Wind Load Design Pnet(psf) = g The method described in this document is valid for flush, no tilt, SolarMount Series applications on either roofs or walls. A. = adjustment factor for building height and exposure category Flush is defined as panels parallel to the surface (or with no more than 3" difference between ends of assembly) with no Kzt = Topographic Factor at mean roof height, h (ft) more than 10" space between the roof surface, and the bottom of the PV panels. I= Importance Factor This method is not approved for open structure calculations. p1et3o(psf) = net design wind pressure for Exposure B, at height = Applications of these procedures is subject to the following ASCE 7-05 limitations: 30 feet, I = 1.0 1. The building height must be less than 60 feet, h < 60. See note for determining h in the next section. For installations You will also need to know the following information: on structures greater than 60 feet, contact your local Unirac Distributor. Basic Wind Speed= V(mph), the largest 3 second gust of wind in the last 50 years. 2. The building must be enclosed, not an open or partially enclosed structure, for example a carport. h (ft) = total roof height for flat roof buildings or mean roof height 3. The building is regular shaped with no unusual geometrical for pitched roof buildings irregularity in spatial form, for example a geodesic dome. Roof Pitch (degrees) 4. The building is not in an extreme geographic location such as a narrow canyon or steep cliff. This manual will help you determine: 5. The building has a flat or gable roof with a pitch less than 45 Effective Wind Area (sf) = minimum total continuous area of degrees or a hip roof with a pitch less than 27 degrees. modules being installed(Step 2) 6. If your installation does not conform to these requirements please contact your local Unirac distributor or a local Roof Zone = the area of the roof you are installing the pv system professional engineer. according to Step 3. If your installation is outside the United States or does not Roof Zone Dimension = a (ft) (Step 3) meet all of these limitations, consult a local professional engineer or your local building authority.
