A turnkey hybrid solar PV system — panels plus battery storage — engineered from your 12-month LESCO billing history and a 2,500 sq ft elevated roof. Sized to your sanctioned load, payback-optimised, and built to keep your office running through outages.
Consumption is steady and modest; the constraint is your sanctioned load, not roof space. A right-sized 6.5 kWp hybrid system offsets the annual bill and adds battery backup at the fastest payback.

| Metric | Value | Note |
|---|---|---|
| Annual consumption | 6,073 KWH | avg 506 KWH / month |
| Peak month | 816 KWH (May 26) | 1.6× average — steady load |
| Average MDI (demand) | 4.1 kW | peak 6 kW |
| Annual bill | Rs 443,677 | effective Rs 70.9 / unit |
| Roof available | 2,500 sq ft (elevated) | fits up to ~34 kWp |
Trina Vertex N 720W, N-type TOPCon bifacial — 7.82×4.27 ft each, ~300 sq ft footprint on the elevated roof.
On-grid hybrid inverter with built-in battery charger, ~1.1× headroom and remote monitoring.
Lithium (LiFePO₄) storage for evening use and seamless backup during grid outages.
Ballasted/aluminium rail structure on the 2,500 sq ft rooftop, wind-load certified.
NEPRA/LESCO net-metering at sanctioned load — monthly credit for surplus export.
Linear panel performance warranty, 10 yr product, 5+ yr inverter, 10 yr battery.
Your roof could fit ~34 kWp, but net-metering caps the credit-earning system at your 6 kW sanctioned load. A 6.5 kWp hybrid plant generates ~9,100 KWH/yr — more than your 6,073 KWH demand — so every unit you consume is free, and the surplus is exported at the lower buyback rate. The battery adds outage resilience without changing the energy math. Sizing up only adds cost against cheaply-credited export, pushing payback from 3.0 to 16+ years. 6.5 kWp hybrid is the payback-optimal, resilience-rich choice at Rs 200/Wp.
| Scenario | System | Cost (feasible all-in) | Payback | Verdict |
|---|---|---|---|---|
| Recommended (hybrid, net-metering cap) | 6.5 kWp | 1.30 M | 3.0 yr | ✅ Best return + backup |
| Roof-max (export credited) | 34 kWp | 6.92 M | 4.6 yr | ⚠ only if buyback improves |
| Roof-max (export curtailed) | 34 kWp | 6.92 M | 16.1 yr | ❌ slow payback |

Every recommendation is traced to your LESCO billing record — no generic assumptions.
We size to your sanctioned load and payback, not to fill the roof — your money works harder.
Hybrid architecture keeps critical loads running through grid outages, with compliant NEPRA net-metering.
Confirm the 6.5 kWp hybrid recommendation and we will schedule a site survey of the elevated roof, finalise the net-metering and battery specification, and deliver a fixed-price turnkey quote.
