Solar Field Staff Attendance & CRM App: Complete Architecture & Case Study

1. The Field Challenge for Solar EPC Companies

Solar Engineering, Procurement, and Construction (EPC) providers manage distributed workforces across rooftops, industrial parks, and remote solar farms. Traditional manual paper logs and generic messaging apps lead to attendance disputes, delayed site surveys, and fragmented customer leads.

2. Features of our City Solar Tech App Case Study

When developing the City Solar Tech field workforce suite, we engineered key capabilities:

• Geo-Fenced Biometric & GPS Check-In: Technicians can only punch attendance when physically within the site perimeter.
• Site Survey & Roof Measurement Forms: Offline-capable photo uploads and inverter sizing calculators.
• Lead Pipeline & Customer CRM: Field reps can log client inquiries and quotation requests on the go.
• Admin Central Command: Live technician map view, attendance reports, and dispatch scheduling.

3. Technology Stack & Offline Sync

Using Flutter cross-platform architecture paired with a fast PHP backend and SQLite local caching ensures zero downtime even in remote locations with poor cellular connectivity.
