FAQ

Frequently Asked Questions

How much does solar installation cost in Pakistan?

A typical residential solar system costs Rs. 250,000–400,000 per kW installed, including panels, inverter, mounting, and installation. Prices vary by brand, installer, and location.

What is net metering?

Net metering allows you to export excess solar electricity back to the grid and receive credit on your bill. Your meter runs backwards when you export, effectively reducing your bill to the net of import minus export.

How long does payback take for solar?

Typical payback period is 3–5 years for residential systems in Pakistan, depending on system size, electricity rates, consumption level, and available sunlight.

Does solar work during cloudy days?

Yes, but at reduced efficiency (20–50% of peak output). Solar panels still generate some electricity on cloudy and overcast days, just less than on sunny days.
