How JIENERGIES Calculates Your Solar Generation
Solar Insolation in Pakistan:
Pakistan receives an average of 5.0 to 5.5 peak sun hours daily. Each 1 kW of installed solar capacity generates approximately 120 to 135 units (kWh) per month, or ~1,500 units annually under standard rooftop tilt (25°–30° South-facing).
Blended Tariff Calculations:
Calculations use current DISCO tariff tables (including Fuel Price Adjustments (FPA), Financing Cost Surcharges, and general sales taxes) which push effective high-slab electricity costs between Rs. 56 and Rs. 65 per unit.
Roof Area Required:
Using our high-efficiency Alps Solar 585W TOPCon modules, approximately 70 sq. ft of shadow-free rooftop space is needed per 1 kW of system capacity.
25-Year Financial Projection:
Lifetime savings reflect a conservative 5% annual grid tariff increase and a minimal 0.5% annual linear degradation guarantee from Alps Solar N-Type cells.
