How the solar payback calculation works
Enter your average monthly bill and system size. The calculator estimates annual generation using Pakistan's average solar yield (~4.5 peak-sun-hours/day across most of the country), values that generation at your current per-unit tariff, and derives simple payback = system cost ÷ annual savings.
Because Pakistani tariffs have risen 15-30% year on year for the past four years, actual payback is typically 6-12 months faster than the simple estimate suggests. Adding net metering (exporting surplus to your DISCO) shortens it further.
Is solar worth it in Pakistan in 2026?
For any household with an unprotected bill above Rs. 15,000/month, the answer is almost always yes. A 5 kW on-grid system costs Rs. 550,000-700,000 installed (with net metering), generates roughly 600-750 units/month year-round, and offsets Rs. 18,000-25,000 of bill at unprotected rates. Payback is typically 3-4 years, after which you have 20+ years of near-free electricity.
Off-grid and hybrid systems cost more (Rs. 800,000-1,200,000 for 5 kW with lithium storage) but eliminate load-shedding dependence on generators and UPS.
