iElecssol —
Solar Monitoring.
Solar Street Light Monitoring System. A centralized mobile application providing real-time visibility into device status, performance metrics, and operational data.
Case Study
Project Overview
iElecssol is a Flutter-based mobile application developed for a government solar street lighting initiative. The application is used by field engineers, administrators, and monitoring teams to manage and monitor solar street light controllers deployed across multiple geographic locations such as districts, blocks, and villages. The system provides real-time visibility into device status, performance metrics, and operational data, helping authorities efficiently manage large-scale solar infrastructure.
Problem Statement
Managing a large number of solar street light systems across different regions is operationally challenging. Traditional monitoring methods lack real-time visibility, making it difficult to detect faults, track performance, and manage installations. Field teams require a centralized system to monitor devices, analyze data, and perform administrative actions efficiently.
Proposed Solution
The solution was to develop a centralized mobile application that allows real-time monitoring and management of solar street light systems. The app integrates with backend APIs to fetch device data, display performance metrics, and enable engineers to manage installations, track faults, and monitor system health remotely.
System Architecture
Modular & Scalable Structure
Modular MVC Setup
Uses a strict modular MVC-based structure separating UI logic (Screens & Widgets), Controller Layer (business logic using GetX Controllers), and Data Layer (Repository pattern for API handling).
GetX Ecosystem
Built using Flutter with GetX serving as the core engine for reactive state management, dependency injection, and centralized navigation without unnecessary UI rebuilds.
Network & Integration
REST APIs integrated securely using the Dio HTTP client with central interceptors. Firebase services integrated for analytics, crash reporting, and notifications.
Core Features
Device Monitoring Dashboard
Displays summary of solar street light systems. Shows device status (active, faulty, disconnected) and provides quick insights into system health.
Device Details & Telemetry
Detailed view of individual devices reporting parameters like battery voltage, solar power, and performance metrics. Helps engineers diagnose issues remotely.
Map Integration
Visual representation of devices on a map. Enables geographic tracking and streamlined navigation for field service teams.
Diagnostics & Fault Logs
View historical fault data and detailed diagnostics logs to assist in troubleshooting and preventative maintenance.
Installation & Data Management
Register new devices by filling deployment data, edit or update existing device records, and manage regional deployment information.

Tech Stack
Your Role & Contribution
Flutter Developer
Served as the sole frontend developer, completely redesigning the entire mobile application from the ground up. Single-handedly integrated all REST APIs using Dio, building out the complete client-server communication layer. Developed all key features including the Monitoring dashboard, Device detail screens, and Diagnostics module. Implemented a robust modular architecture using GetX and collaborated directly with the backend team to ensure scalable system execution in a production-grade environment.
