How to use it
A quick estimate, without the spreadsheet.
Inputs and units
Enter installed cost, monthly generation, percentage consumed on-site, avoided import price per unit and annual maintenance.
Formula
On-site consumption = generation × self-consumed percentage / 100. Annual net savings = on-site units × avoided import rate × 12 − annual maintenance. Simple payback = installation cost / annual net savings.
Worked example
600 monthly units with 70% self-consumption and an illustrative PKR 40 avoided rate saves PKR 16,800 per month before maintenance.
Assumptions and limitations
Values are user assumptions, not live tariffs or generation forecasts. Exports receive no assumed credit. Net-metering/net-billing rules, financing, batteries, degradation, seasonal variation, outages, taxes and replacements are excluded. Fixed bill charges may remain.
