12kW Solar System Price in Pakistan
A 12kW system needs about 21 × 585 W panels and roughly 66 m² of shade-free roof. It typically produces about 1,296 units a month (annual average, after losses).
Estimated cost (panels, inverter and installation)

Cost breakdown
| Component | Basis | Estimate |
|---|---|---|
| Panels (21 × 585 W) | Scraped Rs/W, 20th–80th percentile (Rs 38.0/W – Rs 42.2/W, 78 listings) | Rs 466,830 – Rs 518,550 |
| Inverter (~12 kW) | Scraped listings rated 9.6–15.0 kW (131) | Rs 195,000 – Rs 500,000 |
| Structure, wiring, protection & labour | Assumption Rs 18–30/W (not scraped) | Rs 221,130 – Rs 368,550 |
How this estimate works
- Panels: number of 585 W panels = 12,000 W ÷ 585 W, rounded up (21). Cost uses the 20th–80th percentile of today's real dealer price per watt for 540 W+ panels, so outliers don't skew it.
- Inverter: real listings rated 80–125% of the system size; 20th–80th percentile of their prices. If we lack data, the inverter is excluded and the headline says so.
- Balance of system: mounting structure, DC/AC cables, breakers/SPDs, earthing and installation labour, using a stated planning assumption of Rs 18–30 per watt. This is not a scraped price; installers' quotes vary with roof type and structure height.
- Not included: lithium batteries (see battery prices), net-metering fees and green meter, elevated structures.
- Generation: 12 kW × 4.5 peak sun hours × 30 days × 80% system efficiency ≈ 1,296 units/month.
At the NEPRA un-protected rate for that consumption, 1,296 units would cost about Rs 61,171 in base energy charges per month on the grid (before taxes and adjustments). See the electricity bill calculator.
Frequently asked questions
How many panels are in a 12kW solar system?
About 21 panels of 585 W (12.29 kW DC). With 600 W panels you'd need 20.
How many units does a 12kW solar system produce?
Roughly 1,296 units per month on average in Pakistan, higher in summer and lower in winter or with shading and dust.
Can a 12kW system run an air conditioner?
Yes. A 12kW system can run 4 inverter AC(s) of 1.5 ton during sunny hours alongside normal household load.
