1. Sizing Your Home Solar System Based on Monthly Bill
Quick rule-of-thumb based on current Pakistani electricity tariffs:
- Monthly Bill Rs. 15,000 – 25,000 (300–450 units): Install a 3kW system.
- Monthly Bill Rs. 30,000 – 50,000 (500–800 units): Install a 5kW to 6kW system.
- Monthly Bill Rs. 60,000 – 110,000 (1,000–1,600 units): Install a 10kW system with net metering.
- Monthly Bill Rs. 120,000+ (2,000+ units): Install a 15kW to 20kW system.
2. On-Grid vs Hybrid for Residential Homes
Choose your inverter architecture based on local grid stability:
- Choose On-Grid: If your area has minimal or zero load shedding (e.g., DHA, Bahria Town, Askari) and your goal is pure electricity bill elimination via net metering.
- Choose Hybrid: If your neighborhood experiences daily load shedding or voltage fluctuations, requiring batteries for seamless backup during power cuts.
3. Return on Investment (ROI) and Financial Payback
With residential unit tariffs exceeding Rs. 55 to Rs. 65 per unit in higher slabs, a properly sized residential solar setup saves 70% to 95% of your annual electricity expense, returning 100% of your capital investment within 24 to 30 months.
