How is the system size calculated?
We divide your monthly units by a conservative Pakistan average output for 1 kW of solar, about 125 units per month across the year, and round up to the nearest half kilowatt.
Where do I find my monthly units?
Your electricity bill (LESCO, IESCO, MEPCO, K-Electric or any other DISCO) shows units consumed for the current month and the last 12 months. Use an average of the last 12 months for the most realistic size.
Why is my actual quote different?
Shading, roof direction, panel tilt, inverter choice, batteries and net billing all change the right size. Your installer should confirm the final design on site.
Does the saving include batteries?
No. The estimate assumes daytime solar use and net billing. Batteries add backup during load-shedding but do not increase the units your panels produce.
