Attachment 15 Solar Inspections PV logs.pdf

This is a Solar PV System Field-Inspection Checklist dated November 14, 2024, used to verify compliance and quality of solar photovoltaic installations prior to system activation and interconnection with the utility grid.

The checklist covers a 1,776-module solar installation located at 5001 North Piedra Street, El Paso, Texas 79936, featuring a 42.5 kW inverter and estimated annual production of 5,242 kWh. The system uses a ballast mounting configuration with south-facing orientation and a -20-degree tilt. The pre-inspection section verifies essential prerequisites including utility interconnection permission, qualified installer certification, city permits, electrical documentation, professional engineer stamping, system plans with balance-of-system details, roof structural integrity with minimum 10-year useful life remaining, and component specifications for modules, inverters, and combiner boxes. Additionally, solar resource documentation from high-shading areas and total solar resource fraction (TSRF) verification at 75 percent or greater are required.

The field inspection section for PV modules and arrays validates physical installation compliance with plans, performance optimization without aesthetic compromise, array permanence and neatness, roof penetration security, module condition and specifications, proper wiring with DC-rated fuses and appropriate sizing, conductor suitability with sunlight and temperature resistance, conduit support and accessibility, electrical box functionality, grounding compliance for both module frames and metallic surfaces, dissimilar metal isolation, and concrete-contact prevention for aluminum components. The checklist indicates most items were marked as confirmed ("Yes") or not applicable ("N/A"), with several items marked as "No" regarding design stamps, on-site plans, and roof condition documentation.
