How Many Units Does a 6kW Solar System Produce Per Day in Pakistan?
A 6kW solar system sits between the popular 5kW and 8kW sizes — ideal for homes with higher AC loads or small offices wanting more surplus for net metering. Here’s how much it generates per day across Pakistan’s major cities.
6kW Solar System — Daily Output by City
| City | Summer | Autumn/Spring | Winter | Annual Average |
|---|---|---|---|---|
| Lahore | 26–33 units/day | 23–29 units/day | 15–19 units/day | 21–26 units/day |
| Karachi | 29–36 units/day | 25–32 units/day | 21–26 units/day | 25–31 units/day |
| Islamabad | 25–31 units/day | 21–27 units/day | 13–17 units/day | 20–25 units/day |
| Faisalabad | 27–33 units/day | 24–29 units/day | 15–19 units/day | 22–27 units/day |
| Multan | 29–36 units/day | 25–31 units/day | 17–21 units/day | 24–29 units/day |
Annual Generation & Savings — 6kW in Lahore
| Metric | Value |
|---|---|
| Annual generation | 7,200–8,100 units/year |
| At Rs 50/unit | Rs 360,000–405,000/year |
| At Rs 60/unit | Rs 432,000–486,000/year |
| System cost (on-grid) | Rs 450,000–530,000 |
| Payback period | 13–18 months |
6kW vs 5kW vs 8kW — Which to Choose?
| System | Daily Output (Lahore) | Best For | Price Difference vs 5kW |
|---|---|---|---|
| 5kW | 22–28 units | 1–2 ACs, standard home | — |
| 6kW | 26–33 units | 2 ACs + extra export | + Rs 70,000–90,000 |
| 8kW | 35–44 units | 3 ACs or larger home | + Rs 150,000–200,000 |
A 6kW system generates approximately 20% more than a 5kW system for about 18% more cost. For homes with 2 ACs running simultaneously plus full household load, 6kW provides the headroom a 5kW system can’t. The extra Rs 70,000–90,000 cost pays back in additional generation within 12–18 months.
What a 6kW System Can Run Simultaneously
- 2 × 1.5-ton inverter ACs (full capacity)
- Refrigerator + freezer
- Washing machine (while running)
- Full LED lighting (10–15 lights)
- TV + fans throughout house
- Surplus ~3–5 kW available for export or additional loads
