Design Considerations for Grid-Tied Rooftop Solar PV Systems
Designing a grid-tied rooftop solar PV system is a multi-disciplinary task involving electrical design, structural integrity, solar resource evaluation, shading analysis, and adherence to local codes. This guide provides an in-depth look into the essential design aspects of rooftop solar PV systems with detailed calculations, examples, and practical insights. 📍 Example Location Used: Phoenix, Arizona – one of the sunniest cities in the U.S. 1. Introduction to Grid-Tied Rooftop PV Systems A grid-tied rooftop solar PV system is connected to the utility grid and is designed to offset on-site energy consumption. When solar production exceeds usage, the surplus electricity is exported to the grid (net metering). Key components include: Solar PV Modules Grid-Tied Inverter Mounting Structures DC/AC Cabling and Protection Devices Bi-directional Energy Meter Monitoring System 2. Site and Roof Assessment 2.1 Orientation and Tilt Orientation (Azimuth): Panels should ideally face true south in the U.S. (azi…
