A typical 5kW residential solar system generates roughly 550-750 units of electricity per month, which is enough to significantly reduce or largely eliminate a household's grid bill depending on usage. With net metering, unused units are credited back to you, and most homeowners recover their full installation cost in about 3-5 years, after which electricity is essentially free for the remaining life of the system.
What Determines Your Actual Savings
- System size: Larger systems (10kW) generate more but cost more upfront; smaller systems (3kW) suit lower-usage households.
- Your current consumption pattern: Households with high daytime usage see the fastest direct offset before even relying on net-metering credits.
- Roof orientation and shading: South-facing, unshaded roofs produce closer to the top end of the generation range.
- Seasonal variation: Summer sun boosts generation (though heat can slightly reduce panel efficiency), while winter fog can reduce output on some days.
Typical Savings by System Size
A 3kW system (installed cost roughly PKR 600,000-900,000) suits smaller households with modest usage. A 5kW system (PKR 800,000-1,200,000) is the most common residential choice and can offset a large share of a typical family's bill. A 10kW system (PKR 1,500,000-2,200,000) suits larger homes with high consumption, including air conditioning and electric appliances.

How Net Metering Multiplies Your Savings
IESCO net metering lets excess units you generate during the day offset units you draw at night, effectively using the grid as free storage. Once approved (a process that takes roughly 4-6 weeks from application to activation with complete documentation), your monthly bill reflects only your net consumption. Learn how to apply in our IESCO net metering guide.
Getting an Accurate Savings Estimate
Because savings depend heavily on your specific roof, usage pattern, and current tariff slab, the most reliable number comes from a free site survey where our team reviews your recent bills and roof conditions before recommending a system size. Contact us through the contact page to schedule one.
Frequently Asked Questions
Will solar eliminate my electricity bill completely?
It depends on system size versus usage; many households offset most of their bill, while a well-sized system paired with net metering can bring bills close to zero in favorable months.
Do savings change between summer and winter?
Yes, generation is typically higher in sunnier months and can dip on foggy winter days, though panels still produce usable power in diffuse light.
How soon will I start seeing savings after installation?
Savings begin as soon as the system is commissioned and net-metered, which typically happens within days of installation once IESCO documentation is complete.
