kpower-forecast 2026.2.0

Solar production and power consumption forecasting package.

☀️ KPower Forecast 📈

Production-grade solar production and power consumption forecasting.

Built with Facebook Prophet and powered by Open-Meteo. KPower Forecast provides a high-level API for training and predicting energy metrics with physics-informed corrections.

✨ Key Features

• 🔋 Dual Mode: Specialized logic for both Solar Production and Energy Consumption.
• 🌓 Night Masking: Physics-informed clamping using solar elevation to eliminate "ghost production" at night.
• 🌡️ Weather Integration: Automatic fetching and resampling of temperature, cloud cover, and radiation.
• 🤖 Prophet Optimized: Pre-configured regressors for maximum accuracy.
• 💾 Smart Persistence: Automatic serialization of models to skip retraining when possible.
• ❄️ Heat Pump Mode: Optional temperature correlation for energy consumption models.

🚀 Quick Start

Installation

pip install kpower-forecast

☀️ Solar Production Forecast

from kpower_forecast import KPowerForecast
import pandas as pd

# 1. Initialize for your location
kp = KPowerForecast(
    model_id="rooftop_solar",
    latitude=46.0569,
    longitude=14.5058,
    forecast_type="solar"
)

# 2. Train with your history
# history_df = pd.DataFrame({'ds': [...], 'y': [...]})
# kp.train(history_df)

# 3. Predict the next 7 days
forecast = kp.predict(days=7)
print(forecast[['ds', 'yhat']].head())

🏠 Energy Consumption Forecast

kp_cons = KPowerForecast(
    model_id="house_meter",
    latitude=46.0569,
    longitude=14.5058,
    forecast_type="consumption",
    heat_pump_mode=True # Accounts for heating/cooling loads
)
