Solar System to Run 1 AC in Pakistan 2026 — Size & Cost Guide
Running 1 ac on solar is one of the most common goals for Pakistani homeowners. Here’s the full solar system to run 1 AC Pakistan breakdown. This guide tells you exactly what system size you need, the cost, and what else you can run alongside one air conditioner.
What Size Solar System Runs 1 AC?
| Load | Power Draw (Running) | System Size Needed | On-Grid Price (PKR) |
|---|---|---|---|
| 1 x 1.5-ton Inverter AC | ~950W avg | 3kW on-grid | Rs 255,000–285,000 |
| 1 x 1.5-ton + Home Loads | ~2,000W total | 4kW on-grid | Rs 340,000–380,000 |
How AC Power Consumption Is Calculated
Inverter ACs (the kind 95% of Pakistanis now buy) consume significantly less than their nominal rating. A 1.5-ton inverter AC uses 800W–1,200W on average, not the 1,750W label rating.
| AC Type | Nominal Tons | Actual Running Watts | Daily Units (10 hr) |
|---|---|---|---|
| Inverter Split AC | 1.0 ton | 650–800W | 6.5–8 units |
| Inverter Split AC | 1.5 ton | 850–1,100W | 8.5–11 units |
| Inverter Split AC | 2.0 ton | 1,200–1,500W | 12–15 units |
| Non-Inverter AC | 1.5 ton | 1,500–1,750W | 15–17.5 units |
Recommended System with Full Home Coverage
- System size: 3–4 kW
- Estimated price: Rs 255,000–360,000
- Covers: AC(s) + all typical home loads during daylight
- Net metering: surplus units banked with DISCO
- Inverter type: Hybrid recommended for 4+ hours load shedding
Always buy an oversized system by 15–20%. The extra production costs little extra at install time but provides a buffer for hot summers when AC consumption peaks.
