Structural evaluation was based on site observations and the design criteria listed above. Based on this evaluation, I certify that the existing structure, with upgrades specified in the plans, directly supporting the PV system is adequate to withstand all loading indicated in the design criteria above based on the requirements of the applicable existing building and/or new building provisions adopted/referenced above. This review relies on the roof's structural system having been originally designed and constructed in accordance with the building code requirements and having been maintained to be in good condition. Additionally, I certify that the PV module assembly including all standoffs supporting it have been reviewed to be in accordance with the manufacturer's specifications and to meet and/or exceed all requirements set forth by the ASCE 7 standards for loading. The PV assembly hardware specifications are contained in the plans submitted for approval. Additionally a summary of the structural review is provided in the results summary tables on the following page.
