GlobalPV-RiskDT: An Integrated Techno-Economic and Risk Assessment Platform for Worldwide Rooftop Photovoltaic Investment Decision Support

GlobalPV-RiskDT is an advanced MATLAB-based decision-support platform developed to evaluate the techno-economic, environmental, and financial performance of rooftop photovoltaic (PV) investments across multiple global cities. The framework first calibrates its financial engine against a validated RETScreen Expert building-retrofit case before extending the methodology to a standardized worldwide PV investment scenario. Using NREL Annual Technology Baseline (ATB) technology parameters, IEA emissions data, real electricity tariffs, and Monte Carlo uncertainty analysis, the platform estimates energy generation, lifecycle cash flows, NPV, IRR, simple and equity payback periods, CO₂ emission reductions, and composite investment risk scores. The software automatically generates publication-quality visual dashboards and structured Excel reports, providing researchers, policymakers, investors, and urban energy planners with a transparent, reproducible, and data-driven framework for comparing rooftop PV deployment opportunities and supporting strategic renewable energy investment decisions under uncertainty.
