Solar Rooftop Analyzer

Interactive tool for analyzing rooftop solar potential using AI. Upload a satellite or aerial image to get:

• —Usable rooftop area calculation
• —Solar energy production estimates
• —Return on investment analysis
• —AI-generated recommendations

Architecture

The application follows a modular architecture with distinct processing stages:

graph TD
    A[Upload Image] --> B[Image Processing]
    B --> C[Rooftop Segmentation]
    C --> D[Area Calculation]
    D --> E[Solar Potential Analysis]
    E --> F[ROI Calculation]
    F --> G[LLM Summary]
    G --> H[Display Results]

    subgraph Image Processing
        B --> B1[Convert to PIL]
        B1 --> B2[Preprocess Image]
    end

    subgraph Analysis Pipeline
        E --> E1[Calculate kWh/year]
        F --> F1[Estimate Costs]
        F1 --> F2[Calculate Payback]
    end

    subgraph AI Integration
        C --> C1[OpenRouter Vision API]
        G --> G1[OpenRouter LLM API]
    end
