Energy Calculator Suite

This project is a web application that provides a suite of calculators for detailed energy analysis. It has been expanded from a simple cost calculator to a comprehensive tool for evaluating electricity costs, photovoltaic system savings, and overall energy consumption.

✨ Key Features

The application is divided into two main calculators, accessible from the main page:

1. Advanced Cost Calculator (cost-calculator.html)

This tool simulates electricity consumption and costs, with advanced options for modeling renewable energy sources and storage.

• Device Consumption Simulation:
  • Set the average power of a device (in Watts).
  • Define the start time and duration of the device's operation within a 24-hour cycle.
• Photovoltaic (PV) System Simulation:
  • Include a PV system in the simulation by specifying its peak power (kWp).
  • Select the geographic area, season, and type of day (sunny, cloudy, etc.) to get a realistic production estimate.
  • Option to simulate with a randomized "current weather" factor.
• Battery Storage Simulation:
  • Add a storage battery to the system.
  • Set the battery's capacity (kWh) and its initial charge (%).
• Detailed Results and Analysis:
  • Get a breakdown of energy consumption: from the grid, from the PV system, and from the battery.
  • View the total estimated cost of electricity drawn from the grid.
  • Visualize the simulated energy flows over time with an interactive chart showing device consumption, PV production, grid draw, and battery charge level.
• Multi-language Support: The interface is available in Italian and English.

2. Photovoltaic Savings Calculator (savings-calculator.html)

This calculator is designed to analyze the economic viability of a photovoltaic system based on real consumption data.

• Economic Analysis:
  • Input your total home consumption, consumption from the grid, and energy fed into the grid.
  • Set the purchase cost of electricity (€/kWh) and the selling price for the energy you feed into the grid.
• Specific Utility Management:
  • Add a list of specific electrical utilities (e.g., "Electric Car," "Night-time appliances") with their respective consumption to analyze their cost impact.
  • Group Management: Save and load predefined groups of utilities to speed up repetitive analysis.
• Comprehensive Summaries:
  • Economic Summary: See a clear breakdown of costs from the grid, savings from self-consumption, earnings from selling energy, and the final economic balance.
  • Energy Summary: Analyze the flow of energy in kWh, including self-consumed energy, energy from the grid, energy fed in, and total energy produced by the PV system.
• Visualizations:
  • Interactive bar charts show the breakdown of energy sources (grid vs. PV) and the impact of specific utilities on total consumption.

🚀 How to Get Started

Prerequisites

• A modern web browser (e.g., Chrome, Firefox, Safari, Edge)
• Docker (optional, for running via container)
• Git (optional, for cloning the repository)

Local Execution (Without Docker)

1. Clone the repository (optional):

   git clone [https://github.com/dnviti/EnergyCalculatorWeb.git](https://github.com/dnviti/EnergyCalculatorWeb.git)
   cd EnergyCalculatorWeb
   

   Alternatively, you can just download the project files.
2. Open the pages/index.html file in your web browser to access the main menu and navigate to the desired calculator.

Execution with Docker

1. Make sure Docker is running.
2. Build the Docker image. Navigate to the project's root directory and run:

   docker build -t energy-calculator-suite .
   

3. Run the Docker container:

   docker run -d -p 8080:80 energy-calculator-suite
   

4. Access the application: Open your browser and go to http://localhost:8080.

🐳 Docker Image

The application can be run as a Docker container. The Dockerfile uses a stable Nginx image to serve the static files. The image is automatically built and published to the GitHub Container Registry (GHCR) with every push to the master branch.

Pulling the image from GHCR:

docker pull ghcr.io/dnviti/electricity-calculator-app:latest

---

🔄 Continuous Integration (GitHub Actions)

The .github/workflows/docker-publish.yml file defines a GitHub Actions workflow that automates the building and publishing of the Docker image to GHCR.
