Solar reduces your electricity bill in two ways: it replaces grid electricity with self-generated power during the day, and any surplus you don't use is exported to IESCO through net metering for a credit on your bill. Together, these can cut a typical household's grid electricity purchase dramatically, with most homeowners recovering their system cost in roughly 3 to 5 years.
How Net Metering Turns Your Roof Into a Bill Credit
A bidirectional meter installed as part of the IESCO net metering process tracks electricity flowing both ways: units you pull from the grid, and units you export back when your panels produce more than you're using. Instead of that surplus going to waste, it's credited against your bill, effectively letting you "bank" excess daytime generation. See our guide on how to apply for IESCO net metering for the full application process.
How Much You Could Realistically Save
- A 5kW system generates roughly 550-750 units per month depending on weather and panel orientation.
- Households with high daytime usage (air conditioning, appliances, home offices) see the fastest bill reduction because they consume solar power directly rather than exporting it.
- Typical residential payback with net metering active is roughly 3-5 years, after which generation is essentially free for the remaining system life.
Savings Depend on System Size and Usage Pattern
The size of the reduction scales with how well the system matches your consumption. A 3kW system (PKR 600,000-900,000 installed) suits smaller households, while a 5kW (PKR 800,000-1,200,000) or 10kW (PKR 1,500,000-2,200,000) system suits larger homes with higher summer bills. For a detailed cost breakdown, see our 5kW solar system cost guide.
Maximizing Savings Over Time
Bill savings hold up best when the system is kept clean and monitored — dusty conditions on busy corridors mean quarterly panel cleaning is a common baseline for maintaining output. Regular system monitoring also catches underperformance early, before it quietly erodes your savings.

Frequently Asked Questions
Do I still get a bill if I have solar with net metering?
Yes, but it's typically much lower. You're billed only for net grid consumption after your exported units are credited, and in months with strong generation the bill can be minimal.
How soon will I see savings after installation?
Savings start from your very first billing cycle once net metering is activated, which generally takes 4-6 weeks from application when documentation is complete.
Does cloudy or foggy weather eliminate savings?
No. Winter fog can reduce output on some days, but panels still produce electricity in diffuse light, so savings continue year-round, just at varying levels.
