This page contains considerations for structural and site-related design, electrical equipment, PV modules, and fasteners, considerations unique to the PV system type (rooftop, ground-mounted, carport), and considerations for commissioning and decommissioning. Financial Impact is Substantial: Properly commissioned solar systems deliver 2-8% higher energy production over their lifetime compared to inadequately tested systems, while improperly commissioned systems experience 2-3x higher failure rates in the first five years, potentially costing. Weather-conscious equipment selection and design for photovoltaic (PV) systems can result in a longer PV lifetime and improved system durability. This step—overseen by the local Authority Having Jurisdiction (AHJ)—ensures that the installation aligns with the approved plan set and complies with all safety codes. However, before your new solar system can start powering your home, it must pass a crucial step: the solar panel inspection. Understanding and doing them properly leads to happier clients and a healthier bottom line for solar companies.
