System type
Optional: estimate payback

Divide the total of a recent bill by its units to get your average rate. The estimate assumes the solar units replace grid units at that rate. Under net billing, exported units are credited at a lower buyback rate, so savings can be smaller.

Net metering vs net billing in Pakistan

In February 2026 NEPRA replaced net metering with a net-billing model for new solar consumers. Under net billing, units you export are credited at a lower buyback rate than the price you pay for imported units, so using more of your own solar output directly (daytime loads, or a battery) is worth more than exporting it. Reports put agreements signed before 9 February 2026 outside the new rules, and sources differ on the exact new rate. Read the report.

Rules and rates have been revised more than once, so confirm the current buyback rate and eligibility with NEPRA or your distribution company before you decide on system size or a battery.

Frequently asked questions

How many solar panels do I need in Gujrat?

It depends on your usage. At 5.1 peak sun hours, 500 units a month needs about 4 kW, which is 8 panels of 550 W. 1,000 units needs about 7.9 kW (15 panels).

How many peak sun hours does Gujrat get?

This calculator uses 5.1 peak sun hours per day as a planning average for Gujrat, which is 4% below the 5.3 average across the cities in the dataset. It is a planning value, not a measurement; you can change it in the wizard.

How many units does a 5 kW solar system produce in Gujrat?

About 632 units a month on average (21.1 units a day), more in summer and less in winter.

Which electricity company serves Gujrat?

Gujrat is in Punjab and is served by GEPCO. Your distribution company handles solar interconnection applications and sets the rules for exporting surplus power.

Is net metering still available?

NEPRA moved new solar consumers from net metering to net billing in February 2026. Reports say earlier agreements are outside the new rules and that new buyback rates are lower, but sources differ. Confirm the current rules with NEPRA or your distribution company.
