Installation

Prerequisites

• Flutter SDK (3.0.0 or higher)
• Dart SDK
• Android Studio / VS Code
• Android/iOS device or emulator

Steps

1. Clone or create the project:

flutter create solar_panel_app
cd solar_panel_app

2. Replace the files:

   • Copy all the provided Dart files into their respective directories
   • Replace pubspec.yaml with the provided configuration

3. Install dependencies:

flutter pub get

4. Run the app:

flutter run

Dependencies

dependencies:
  flutter:
    sdk: flutter
  provider: ^6.0.5        # State management
  cupertino_icons: ^1.0.2 # iOS style icons

Static Data

The app uses static/mock data for demonstration:

Solar Generation Data

• 7 days of hourly data
• Simulated solar generation pattern (peak at noon)
• Realistic consumption patterns (morning and evening peaks)
• Efficiency calculations

Demo Users

• Email: demo@solar.com, Password: password123
• Email: john@example.com, Password: john123

Pre-configured Maintenance Tasks

• Panel Cleaning (High priority)
• Inverter Check (Medium priority)
• Wire Inspection (Medium priority)
• Performance Analysis (Low priority)

Usage Guide

Login

1. Launch the app
2. Use demo credentials or register a new account
3. Access the dashboard

Monitor Solar Data

1. Navigate to Dashboard
2. View current generation, consumption, and efficiency
3. Check today's summary statistics
4. Analyze hourly power chart

Control Panels

1. Go to Panel Control screen
2. Switch between Auto/Manual mode
3. Adjust azimuth angle (direction)
4. Adjust tilt angle
5. View visual orientation indicator

Manage Maintenance

1. Open Maintenance screen
2. View upcoming and completed tasks
3. Check/uncheck tasks to mark completion
4. Add new custom tasks with priority and date
5. Delete tasks if needed

Customization

Adding Real API Integration

Replace the static data providers with API calls:

// In solar_provider.dart
Future<void> fetchRealTimeData() async {
  final response = await http.get('your-api-endpoint');
  // Parse and update state
}

Adding Notifications

Use flutter_local_notifications package:

dependencies:
  flutter_local_notifications: ^16.0.0

Database Storage

Replace in-memory storage with SQLite:

dependencies:
  sqflite: ^2.3.0
  path_provider: ^2.1.0

Future Enhancements
