Shadow Analysis and Layout Optimization Using PVsyst for Rooftop Solar PV Systems
Proper shadow analysis is essential for any rooftop solar PV design because shading dramatically reduces energy output. Using PVsyst , you can simulate real-world conditions, calculate shading losses accurately, and optimize the array layout for the best performance. This complete guide explains the technical concepts, equations, AND gives you a clear step-by-step workflow to use PVsyst — with examples — so you can do it confidently. 🔍 1. Why Shadow Analysis Matters Even partial shading of a single cell can lower the power output of the whole module or string. Shading creates mismatch losses, hot spots, and higher risk of long-term damage. A well-designed system must avoid shading especially during the solar window (9 AM – 3 PM) . 📊 FACT: A single tree shadow on 10% of an array can reduce total energy output by up to 30%! ✅ 2. How PVsyst Helps PVsyst is one of the most trusted PV design and simulation tools worldwide. It includes: 3D shading scenes to model your roof and surroundings. Sun path…
