Using Data to Support Solar Panel Proposals

Essential inputs for PV syst report When you're preparing a PVsyst report (or any detailed simulation) for a ground-mounted solar power project, ensuring accuracy requires careful attention to the inputs you provide. Let’s walk through the essential inputs you should focus on: 📌 1. Site-Specific Meteorological Data Solar Resource Data (Irradiance) Global Horizontal Irradiance (GHI), Diffuse Horizontal Irradiance (DHI), and Direct Normal Irradiance (DNI) are crucial. Source: On-site measurements (preferred), or reputable databases (Meteonorm, NASA-SSE, SolarGIS, etc.). Time Resolution: Hourly data (better accuracy than monthly averages). Ambient Temperature Affects module temperature and hence energy output. Wind Speed Important for module cooling and structure loading (especially relevant in desert or high-wind areas). 📌 2. Detailed Terrain Data (Shading & Layout) Digital Elevation Model (DEM) or Topography Necessary to model horizon shading and potential row-to-row shading. Tools: Drone surveys, satellite data, or on-site measurements. Site Layout Module row spacing (pitch), tilt angle, azimuth, table height, and ground coverage ratio (GCR). Include trackers (if applicable) — single-axis or dual-axis — and define their geometry. 📌 3. Module and Inverter Specifications PV Module Manufacturer datasheet with key electrical parameters: Nominal power, temperature coefficients, NOCT, bifacial gain (if bifacial modules are used). IAM (Incidence Angle Modifier) and low-light performance. Inverter Make and model, including: Nominal AC power, voltage range, efficiency curves, MPPT voltage window, clipping loss characteristics. 📌 4. Electrical Configuration String Configuration Number of modules per string, number of strings per inverter, wiring losses. Cabling DC and AC cabling lengths and sizes to model ohmic losses. 📌 5. Albedo Reflectivity of the ground surface. Use site-specific measurements or estimates from literature: Grass: 0.2–0.25 Gravel: 0.25–0.35 Sand: 0.3–0.4 Snow: 0.7–0.9 (if relevant) 📌 6. Soiling & Losses Soiling Losses Based on local conditions and maintenance practices (e.g., 1–4% annual). Other Losses Module mismatch, inverter mismatch, light-induced degradation, availability, etc. 📌 7. Bifaciality (If Applicable) Rear-side gains from bifacial modules. Requires ground reflectivity/albedo, row height, row spacing, and any obstructions. 📌 8. System Losses & Performance Factors Module Degradation Annual degradation rate (typically 0.5–0.8%/year). Temperature Coefficient From module datasheet; affects output in high-temperature environments. ✅ Key Notes On-site measurements are always preferred over generic datasets, especially for large projects. Accurate terrain and layout data significantly improves shading and horizon loss estimation. Regular calibration and updates to PVsyst models are advisable as project details evolve (e.g. changes in module supplier or updated site surveys).

🌞 Why Every Solar Project Needs a PVsyst Report Before any solar project reaches construction, one critical step ensures its technical and financial success — the PVsyst Simulation Report. At Amrit Energy, we use PVsyst to simulate and analyze every design before execution. Recently, we prepared a detailed report for a 999 kWp single-axis tracker system at the Roman Catholic Diocese of Brescia, Italy. Here’s why a PVsyst report is vital 👇 ✅ Accurate Energy Forecasting It estimates annual generation (e.g., 1711.7 MWh/year in this project) based on real climatic and system parameters. ✅ Loss Analysis & Optimization The report highlights each energy loss — from soiling and shading to inverter and transformer losses — helping us fine-tune the system for maximum yield. ✅ Performance Ratio (PR) Evaluation A PR of ~89.6% indicates high system efficiency and design accuracy. ✅ Financial Feasibility (P50–P90) PVsyst provides probabilistic output data to support ROI, payback, and risk assessment. ✅ Professional Credibility For EPCs, developers, and investors, PVsyst-backed reports add transparency and confidence during feasibility, tendering, and financing stages. At Amrit Energy, we don’t just design solar systems — we engineer confidence through data ☀️ 📊 Interested in a PVsyst simulation for your upcoming project?
