Worth it? · after 9 Feb 2026
Yes — if you eat your own kWh. No — if you planned to sell them at retail.
Competitor pages still advertise 2-year payback on 1:1 net-metering. That product is closed for new files. Self-use at Rs 37–55 still pays. Export at ~Rs 11 is a rounding error.
Still a yes
Upper-slab bills, afternoon AC, load-shedding at night (hybrid + LFP), factories with daytime motors, tube wells in the sun. Tariff up ~140% since FY2021; plates cheaper. The boom math is still there — just not the export math.
Maybe
Small bills under ~Rs 8k, tenants without roof title, 100% night load with no battery budget, on-grid-only on a dead feeder. Run the calculator before a salesman does.
No
Oversizing a 10 kW array on a 3 kW sanctioned load to “sell to WAPDA.” PERC leftover + PVC + 16 SWG. Four tubulars for two ACs. Paying retail for a shop green-meter.
| 6 kW example (Lahore PSH 5.1) | On-grid, 75% self-use | Hybrid + 5 kWh LFP |
|---|---|---|
| Yield after 0.78 derate | ~715 kWh / month | same PV |
| Self-use @ Rs 48 | ~Rs 25,700 | higher if nights shift off-grid |
| Export @ Rs 11 | ~Rs 2,000 | less export, more self-use |
| Street capex band | ~Rs 1.1–1.6 million | ~Rs 1.7–2.5 million |
| Simple payback | ~4–6 yr if the feeder is reliable | ~5–8 yr plus you still have fans at 2 a.m. |
Simple payback ignores inverter/LFP replacement year 8–12 and tariff inflation. It is a sketch. Use the ROI calculator on your bill.
