Solar System Size Estimator
Instant · no signup neededEstimate the solar system size (in kW) and approximate number of panels needed to cover your electricity usage, based on your average monthly units from your electricity bill.
Uses Pakistan's average of 4.5 peak sun hours per day and an 80% system-loss allowance (inverter, wiring, dust, temperature). A general planning estimate only — actual system design depends on roof space and orientation, shading, backup/battery needs, and your real load profile.
