Your bill, decoded.
Two minutes, three inputs, every assumption shown. This gives you an honest ballpark — the exact quote comes free with your survey.
Assumptions used (tap to view)
- Blended effective tariff: Rs 60 per unit (kWh), including duties and taxes
- Karachi solar yield: 4.5 peak sun hours/day, 80% performance ratio
- Indicative installed cost: Rs 135,000/kW (on-grid) · Rs 190,000/kW (hybrid with battery)
- Bill offset: up to 85% (on-grid with net metering) · up to 90% (hybrid)
- Figures are indicative estimates, not a quote. Equipment prices and tariffs change; your survey fixes the real numbers.

How this works
Your bill tells us your monthly units. Karachi sunshine tells us how many kW of solar produce them. From there: system size, cost range and payback — with the assumptions listed openly on the left.
