How to Conduct a Solar PV Site Survey — Step by Step
A thorough site survey is the foundation of every reliable solar PV installation. It turns a promising idea into an accurate design, correct equipment choices, a realistic production estimate, and a smooth permitting/installation process. Below is a practical, step-by-step guide you can use in the field — with the tools, measurements, a worked example, and common FAQs. Quick overview (why it matters) A site survey collects the physical, electrical and environmental facts needed to size the system, plan the mounting and wiring, estimate energy yield, identify permitting constraints, and produce the bill of materials and cost estimate. Doing it well avoids rework, unexpected costs, and poor long-term performance. For solar resource numbers you’ll typically use modeled GHI (global horizontal irradiance) maps first, then verify shading and local conditions on site.
