Who a 7kW System Suits
A 7 kW system uses about thirteen 550W panels and generates roughly 28-31 units on a good day – enough for a larger home running two inverter ACs alongside the usual fans, lights and appliances. It is a mainstream net-metering size in Pakistan for households with bills around Rs 30,000-50,000, and typically pairs with a single-phase or entry three-phase inverter. Plan for about 34 square metres of clear, south-facing roof. Because 7 kW comfortably covers most middle-class family loads while exporting surplus during the day, it is frequently the size installers recommend as the right-size balance between upfront cost and bill elimination.
7kW Solar System Price in Pakistan 2026 – 3-AC Home Guide
A 7kW solar system is ideal for large Pakistani homes running 2–3 air conditioners along with all standard loads. Generating approximately 28–38 units per day, it can eliminate monthly bills of Rs. 55,000–100,000+. Total installed cost is Rs. 800,000–1,300,000. It fills the gap between the popular 6kW and 8kW system sizes — giving homeowners more power than a 6kW without the higher cost of a full 8kW setup.
7kW Solar System Price Breakdown 2026

| Solar Panels | 12–13 × 580W (LonGi/Jinko) | Rs. 330,000 – Rs. 420,000 |
| Hybrid Inverter | 7kW–8kW hybrid (Growatt/Deye/Sungrow) | Rs. 240,000 – Rs. 350,000 |
| Batteries | 8–10kWh LiFePO4 or 4×200AH lead-acid | Rs. 160,000 – Rs. 420,000 |
| Mounting & BOS | Galvanized structure, DC cables, protection | Rs. 70,000 – Rs. 110,000 |
| Installation | Full professional install, commissioning | Rs. 55,000 – Rs. 85,000 |
| Total (lead-acid batteries) | Rs. 855,000 – Rs. 1,065,000 | |
| Total (lithium batteries) | Rs. 895,000 – Rs. 1,385,000 |
💡 Why 7kW vs 6kW or 8kW? 7kW sits in a pricing sweet spot — it handles 3 ACs simultaneously (unlike 6kW which struggles with a third AC at full load) while costing Rs. 150,000–200,000 less than a full 8kW system. Ideal for homes where an 8kW feels like overkill.
What Can a 7kW System Run?
| Appliance | Power Draw | Can 7kW Handle? |
|---|---|---|

| Refrigerator (No-Frost) | 180W | ✅ Yes |
| TV, laptop, chargers | 200W | ✅ Yes |
| 1-ton Inverter ACs (×2) | 1,800W | ✅ Yes |
| 1.5-ton Inverter AC (×1) | 1,400W | ✅ Yes simultaneously with 2×1-ton |
| 2-ton Inverter AC (×1) | 2,200W | ✅ Yes (with reduced other loads) |
| Electric Geyser (2kW) | 2,000W | ⚠️ Briefly, solar hours only |
Is a 7kW System Right for You?
- Monthly electricity bill is Rs. 55,000–100,000
- Running 2–3 inverter ACs (1-ton or 1.5-ton each)
- Large 4–5 bedroom house with full kitchen appliances
- Budget of Rs. 900,000–1,200,000 for the complete system
- You want net metering to export excess daytime generation to WAPDA

Frequently Asked Questions
❓ How much does a 7kW solar system cost in Pakistan 2026?
A complete 7kW solar system costs Rs. 855,000–1,065,000 with lead-acid batteries, or Rs. 895,000–1,385,000 with lithium storage. The system typically includes 12–13 high-efficiency panels (580W), an 8kW hybrid inverter, battery bank, mounting structure, and professional installation.
❓ How many ACs can a 7kW solar system run in Pakistan?
A 7kW system comfortably runs 2 × 1-ton inverter ACs simultaneously alongside all other standard home loads (fans, lights, fridge, TV). Running 3 ACs simultaneously is possible when all three are newer inverter units consuming less than 800W each — but requires careful load management.
❓ Should I get a 6kW or 7kW solar system in Pakistan?
Choose 7kW if you have 3 ACs or large 1.5-ton or 2-ton units. A 6kW system handles two 1-ton ACs well but struggles when all three ACs run simultaneously. The Rs. 150,000–200,000 premium for 7kW pays for itself in load coverage. If you only need 2 ACs, 6kW is the better value.
❓ How many units does a 7kW system generate per day in Pakistan?
A 7kW system generates 28–38 units per day in Pakistan’s climate — averaging around 32 units/day annually. Summer peaks at 36–42 units/day (more solar hours, but panels run slightly less efficiently in extreme heat). Winter drops to 24–30 units/day.
