Installation Process

Clear milestones, predictable timelines.

1
Site assessment & shading study
~1–2 hrs
Laser/phone LiDAR, roof scan, tilt/azimuth capture and horizon mask. Shading losses measured with seasonal impact.
Output: Assessment report & photo log
2
System sizing & engineering design
1–2 days
PVsyst yield estimate, stringing, conductor sizing, earthing & lightning protection. Structural checks for wind uplift.
Output: Single-line diagram (SLD) & BOM
3
Permits, net-metering, DISCOM approvals
3–10 days*
We prepare and file all forms, drawings and proofs. Follow-ups handled end-to-end.
Output: Approval & inspection slot
4
Mounting, wiring, safety checks
1–3 days
Anchors/rails fixed, panels mounted, MC4 terminations, DC/AC dressing, earthing & SPD. Safety toolbox talk daily.
Output: Installed array & tidy rooftop
5
Testing, commissioning, documentation
Half day
IV-curve, insulation & polarity tests. Inverter config, Wi-Fi/monitoring, handover and user training.
Output: Test reports & warranty kit

*Approval windows vary by DISCOM and inspection backlog.

Short answers to common questions.

How long does a typical 5–10 kW rooftop take?

Survey and design in 1–2 days, approvals vary by DISCOM (3–10 days). On-site install is usually 1–2 days, commissioning the same day.

Will drilling damage my roof?

We use correct anchors & sealants for RCC/tile/tin. All penetrations are sealed and water-tested, with workmanship warranty.

What tests are done before handover?

Insulation resistance, polarity, IV-curve (where applicable), string voltages, earthing & SPD checks, and live yield verification.

Do you set up the monitoring app?

Yes — owner login, alert thresholds and basic training are part of commissioning. We also offer AMC with periodic cleaning.
