PVDes

MATLAB tool for Egyptian solar systems. Optimizes PV + battery + inverter for off/on-grid, with ROI, LCOE, payback & smart load analysis.

PVDes is a professional solar system design tool developed in MATLAB that helps optimize off-grid and on-grid solar installations for Egyptian households. It provides detailed financial and technical analysis to make solar investment decisions smarter and more data-driven.

Key Features:

• Load Profile AnalysisImport consumption data with intelligent time conversion (handles Excel serial times, HH:MM formats, and decimal hours)
• Smart Optimization EngineFinds the most cost-effective combination of PV panels, batteries, and inverters
• Comprehensive Financial AnalysisCalculates ROI, payback period, LCOE, and 25-year net savings
• Interactive GUIProfessional interface with real-time visualizations of consumption and generation curves
• Device SimulationAdd hypothetical devices to test their impact on system sizing

Advanced Cost Modeling:

The tool uses fitted exponential equations based on recent market data.

Egypt-Specific Assumptions:

• 5.5 Peak Sun Hours daily (Egyptian average)
• 18% PV Panel Efficiency (modern monocrystalline)
• 90% Battery Round-Trip Efficiency
• 80% Depth of Discharge for battery longevity
• 3-Year Battery Replacement Cycle
• 25-Year Project Lifetime

Technical Highlights:

The optimization engine performs exhaustive search across all component combinations, evaluating:

1. Energy Requirements (daily kWh consumption)
2. Power Requirements (peak kW demand)
3. Financial Metrics (ROI, payback, LCOE)
4. System Performance (energy coverage %)

For off-grid systems, it minimizes cost while ensuring 99% energy independence. For on-grid systems, it maximizes 25-year net savings.
