About this estimate
How is the system size calculated?
We divide your monthly bill by your average cost per unit to estimate monthly consumption, apply the share you want solar to cover, then divide by the typical monthly output of 1 kW of solar in Karachi (about 130 kWh after losses).
Why might my final quote differ from the calculator?
Roof orientation, shading, available space, your daytime vs night-time usage, battery needs and current net-metering rules all affect the final design. A site survey accounts for all of these.
What is a typical cost per unit in Karachi?
It varies by consumer category, slab and taxes. Divide your total bill by the units consumed on a recent K-Electric bill for the most accurate figure.
