Solar Net Metering Calculator

Net metering lets a solar homeowner feed surplus electricity to the grid and offset it against units consumed at night or on cloudy days. This Solar Net Metering Calculator estimates what net metering is worth to you: your offset, your net bill and the effective saving on your solar investment.

The calculation compares your solar generation with your consumption across day and night. Surplus daytime units are exported and credited; night-time units are drawn from the grid and charged — the difference is your net bill.

In Pakistan, net metering is available to residential and commercial consumers with approved systems, and the export credit appears on the same bill. Because exported units are credited, the value of net metering depends on how well your generation matches your daytime consumption.

Sizing for net metering is different from sizing for backup: you want generation matched to total consumption rather than peak load. Use this tool to model your export credit and confirm the investment case before applying with your DISCO.
