PV Radiation vs Generation Analyzer

[Hourly solar radiation vs. generation capacity | Hourly solar radiation across the year] - Sample photovoltaic venture (São Paulo, Brazil)

---

Description

This tool compares solar hourly radiation (from PVGIS) with photovoltaic generation capacity (from ANEEL ventures), factoring in system losses. It performs geospatial matching between energy projects and radiation data, then generates a comparative visualizations.

---

Key Features

• 🌍 Geospatial Coordination
  Matches ventures to nearest radiation coordinates using scipy.spatial.cKDTree
• 📉 Loss Modeling
  Accounts for:
  • Temperature derating
  • Annual degradation
  • System losses
• ⚡ Parallel Processing
  Uses multiprocessing to handle large datasets
• 📊 Visualization
  • Hourly radiation vs. generation curves
  • Key metrics overlay:
    • Total radiation energy (kWh/m²)
    • Generated energy (kWh)
    • System loss percentage

Usage

from src.curve_generator import curve_generator
curve_generator(geocodes=[3550308])
# Analyze ventures in São Paulo, SP (geocode 3550308)

Output Structure

After

curves/  
└── SP/                  # State acronym (ex: SP = São Paulo)

Dependent Repositories

This project relies on data processed by:

• ANEEL Photovoltaic Cleaner
  Provides cleaned ANEEL venture data in the required gd-cities/ structure
• PVGIS Parallel API Client
  Generates radiation timeseries stored in data v5.3/ directory structure
