Solar Power Forecast

Explore our 24-hour energy production forecast for the House Roof System, generated using a custom-built AI model trained on more than 1,300 days of historical weather and solar production data. This interactive dashboard visualizes real-time AI predictions, GTI-based forecasts, and actual inverter production — all compared in a detailed chart. You’ll also find model performance metrics (R², MAE), a progress bar of today’s energy generation, and historical accuracy tables showing how well predictions matched reality.

Solar Power Monitoring

While our system began with simple dashboards, it has evolved into a powerful, custom-built energy management platform. At its core is a suite of lightweight Python programs designed specifically for solar forecasting, data processing, and system monitoring. These tools provide enhanced real-time and historical insights, deeper analytics, and fine-grained performance tracking across both solar arrays.

Data from the inverters is fetched directly via APIs and processed locally on a Raspberry Pi. From there, the system prepares structured datasets and uploads them to a public-facing web server, where they are rendered in clear, responsive HTML dashboards. This approach ensures full control over the data pipeline while maintaining maximum flexibility and transparency.

All solar production and energy usage data is continuously stored in a local PostgreSQL database, providing a robust, scalable foundation for long-term retention and advanced analytics. With this architecture, the system can generate detailed daily, monthly, and yearly statistics, perform performance comparisons across seasons, detect anomalies, and optimize charging and consumption behavior.

Ultimately, this self-contained, end-to-end solution gives me real-time awareness and long-term perspective — empowering data-driven energy decisions and sustainable smart home management.

House Roof System

• 24 × 370W solar panels
• South-facing (180°) for optimal energy generation during peak sunlight hours
• Designed to capture the most sunlight throughout the day, ensuring consistent power production for our home

Studio Roof System

• 4 × 410W solar panels
• West-facing (270°) to extend solar production into the evening
• Strategically placed to capture the late-afternoon and evening sun, complementing the house system’s output

Compare energy production of both our systems.
