Visualizing production, consumption & self-sufficiency in residential energy systems

Challenge

This dashboard provides a clear visual overview of energy generation, self-consumption, and match rate across time. Developed to help households or energy consultants analyze consumption behavior, it reveals inefficiencies and guides optimization decisions in self-sufficient energy systems (e.g. solar).

Poljects’ Solution

By visualizing data for August and September, the dashboard identifies trends and deviations in production and usage. The dynamic line chart displays:

• Total energy production (green)
• Household self-consumption (blue)
• Match rate between production and use (orange)

Below the graph, a quantitative insight table summarizes key metrics such as:

• Production change vs previous month
• Consumption drop
• Total self-sufficiency rate (match rate)

Features:

• Dual-axis graph for energy (Wh) and match rate (%)
• Monthly comparisons to surface seasonal patterns
• Automated KPI calculation
• Built with Python (Pandas + Matplotlib) and integrated into a web UI

Outcome

With actionable metrics and clear visuals, this tool helps energy-conscious users make informed decisions on how to improve their energy efficiency and storage strategy.
