1. Is 8kW the Right Size? — Pakistan Load Guide
An 8kW system is Pakistan's "large family" sweet spot — generating 765–1,200 kWh/month depending on city, enough to cover monthly bills of Rs. 35,000–65,000. It's the right upgrade from 5–7kW when summer bills remain high despite existing solar.
8kW suits you if:
- Monthly electricity bill: Rs. 35,000–65,000 (roughly 800–1,400 units/month)
- You run 2–3 inverter ACs simultaneously in summer peak
- Home has 4–5 large bedrooms or is a double-storey villa
- Your existing 5kW or 7kW system cannot cover summer bills adequately
- You want a 10–15% buffer over a 7kW system to account for heat losses

Frequently Asked Questions
- 8kW on-grid budget (JA Solar + Solis/Growatt): Rs. 7–9.6 Lac
- 8kW on-grid mid (Trina + GoodWe EM): Rs. 8.6–11.4 Lac

Lahore prices — other cities 5–20% higher. Include net metering application in all prices.
8kW system in Lahore generates ~850 kWh/month annual average. Summer (April–September): ~1,020 kWh/month. Winter with smog (Nov–Feb): ~600 kWh/month. Annual total: ~10,200 kWh. Annual savings at Rs. 45/unit: ~Rs. 4.59 Lac. Payback on Rs. 8–10 Lac on-grid system: 1.9–2.4 years.
If your monthly bill is Rs. 30,000–50,000 and you run 2 ACs: 7kW is adequate. If summer bills exceed Rs. 45,000 or you run 3 ACs: 8kW gives a meaningful buffer. Price difference between 7kW and 8kW is just 2 extra panels (~Rs. 50,000–70,000) plus slightly larger inverter — worth it if you are consistently undersized in summer. Better to size right now than face another upgrade in 2 years.
GoodWe EM 8kW is the top pick: sub-20ms seamless switching, generator input (critical for 6+ hour load-shedding), SEMS monitoring, Pylontech BMS compatibility. Sungrow SH8RT is premium alternative with best efficiency — but lacks generator input. Solis RHI 8kW is the best budget option with full generator input and off-grid capability. Avoid on-grid inverters for any 8kW system in areas with 4+ hours daily shedding.
15 panels × 550W = 8,250W DC. Each 550W panel: ~2.28m × 1.13m = 2.6 m². 15 panels: ~39 m² panel area. With spacing and walkways: 50–55 m² south-facing unshaded roof area required. Ensure no shading from water tanks, AC units, or new construction between 9am–3pm for maximum generation.
For 8-hour night backup with 1 AC + basics (~900W avg): 900W × 8 hrs = 7.2 kWh → 2× Pylontech US5000 (9.6kWh usable). For 2 ACs + basics (~1,700W): 1,700W × 8 hrs = 13.6 kWh → 3× US5000 (11.52kWh usable). Most Lahore buyers with 8–12 hour daily shedding choose 2× US5000 for 1 AC coverage — adds Rs. 4.2–5.2 Lac to system cost.
Depends on your load-shedding hours. Under 4 hours daily: on-grid is fine and gives better ROI (Rs. 8–10 Lac vs Rs. 13–17 Lac). 4–6 hours: borderline — consider 'battery-ready' hybrid inverter without battery for now, add battery later. 6+ hours: hybrid + battery is strongly recommended. Generator savings alone (Rs. 15,000–20,000/month) justify the extra Rs. 6–8 Lac investment within 2.5 years.
8kW on-grid (Lahore, Rs. 8 Lac): ~1.9 years. 8kW on-grid mid (Rs. 10 Lac): ~2.2 years. 8kW hybrid + 10kWh Pylontech (Rs. 15 Lac): ~2.4 years including generator savings. After payback: 22+ years of Rs. 4–5 Lac/year savings = Rs. 1.0–1.7 Crore total 25-year return. Solar is one of Pakistan's best investments in 2026.
