PM SuryaGhar Solar Field Management Application
A custom Progressive Web Application deployed for 100 field agents across 10 subcontractors, covering survey and feasibility capture for 16,000 homes across 3 locations at zero license cost
An EPC company managing PM SuryaGhar Muft Bijli Yojana rooftop solar installations across 16,000 homes needed field agents to conduct surveys and assess installation feasibility across 3 locations.
- Microsoft licenses for 100 field users across 10 subcontractors were cost-prohibitive.
- The platform had no offline mobile support for teams working in low-connectivity areas.
A custom Progressive Web Application was built for field agents to capture survey data and feasibility assessments on mobile, with or without internet connectivity.
- Survey: Field agents create customer records on-site, logging details required for the installation assessment.
- Feasibility: Agents assess whether solar panels can be installed at the location and record the outcome against the customer record.
- Installation: Field staff scan serial numbers for 4 panels and 1 inverter per home via barcode scanner, tying hardware to the customer record.
- Inventory and reporting: EPC team and subcontractors track stock through the app, with records exportable directly for government reporting under the PM SuryaGhar scheme.
- Access control: Each subcontractor views only their assigned location; the EPC team sees across all 3 locations.
| Impact Metric | Before | After |
|---|---|---|
Microsoft license cost | ₹2,82,240- ₹3,52,800 per year | No License cost |
Data loss risk | High, no offline support, records lost or delayed | Zero, offline sync captures all records |
Serial number entry errors | ~8–10% error rate (manual text entry) | ~0% (barcode scan) |
Role-based and location access keeps each subcontractor's records separate without manual admin overhead. Offline sync ensures data is captured at the site regardless of connectivity, which is the primary constraint for field teams working across 3 locations at this scale.
