How to Calculate Your Home Solar System Savings in Pakistan 2026
If you are wondering how to calculate your home solar system savings in Pakistan 2026, you are not alone. With electricity tariffs ranging between PKR 40–65 per unit and frequent fuel adjustments, many households are turning to solar for more predictable and lower energy costs. This guide explains how to calculate your savings using realistic, Pakistan-specific numbers, updated policies, and practical examples.
Understanding Solar System Cost in Pakistan 2026
Before calculating savings, you need a clear idea of installation costs. Prices vary based on exchange rates, equipment quality, and installer margins.
- 5 kW system: PKR 700,000 – 1,100,000
- 10 kW system: PKR 1.3M – 2.2M
- 15 kW system: PKR 2.2M – 3.2M
Typical component costs include:
- Panels: PKR 28–40 per watt
- Inverters: PKR 120,000–600,000
- Batteries: PKR 120,000–180,000 per kWh
- Installation: PKR 30,000–80,000 per kW

How Many Units Does a Solar System Generate in Pakistan?
Solar production depends on your city and peak sun hours (PSH).
- Karachi: 5.5–6.5 PSH
- Lahore: 4.5–5.5 PSH
- Islamabad: 4–5.5 PSH
Average generation per kW:
- 120–150 units per month
Estimated outputs:
- 5 kW: 600–800 units
- 10 kW: 1,200–1,600 units
- 15 kW: 1,800–2,400 units

How to Calculate Your Home Solar System Savings in Pakistan 2026
Follow this step-by-step method to estimate your savings accurately:
- Check your monthly electricity usage (units).
- Calculate your effective tariff (including taxes).
- Estimate solar generation based on system size.
- Divide usage into self-consumed and exported units.
Example Calculation
Household data:
- Usage: 1,000 units/month
- Tariff: PKR 50 per unit
- System: 10 kW producing 1,400 units/month
- Self-consumed units: 900 × 50 = PKR 45,000
- Exported units: 500 × 20 = PKR 10,000
- Total savings: PKR 55,000/month
This example shows why maximizing daytime usage is critical for better returns.
Net Metering in Pakistan 2026: What You Must Know
Net metering continues to improve savings, although at reduced export rates.
- Export rates: PKR 15–30 per unit
- Policies vary by DISCO (LESCO, IESCO, K-Electric, etc.)
- Approval timelines can differ significantly
Key insight: Systems designed for self-consumption perform better financially than oversized systems.

Solar Payback Period in Pakistan
Payback depends on system cost and energy savings.
- Without batteries: 3–5 years
- With batteries: 5–8 years
Example:
- System cost: PKR 1.8M
- Annual savings: PKR 540,000
- Payback period: approximately 3.3 years
Batteries vs Net Metering: Which Is Better?
Batteries: Provide backup and increase self-consumption.
Net Metering: Lower upfront cost but reduced export value.
Best approach:
- Urban areas: Start without batteries
- High-outage areas: Consider hybrid systems
Best System Size for Your Home
- 5 kW: Suitable for PKR 25,000–50,000 monthly bills
- 10 kW: Suitable for PKR 50,000–100,000 monthly bills
- 15 kW+: Suitable for high-usage homes
Avoid oversizing purely for export purposes.
Common Mistakes When Calculating Solar Savings
- Ignoring slab-based tariff changes
- Overestimating export income
- Not accounting for seasonal variation
- Ignoring inverter efficiency losses (5–10%)
- Skipping maintenance costs
Frequently Asked Questions
How do I calculate solar savings at home in Pakistan?
Multiply the solar units you use directly by your electricity tariff, then add export credits from net metering. Subtract any remaining grid usage to determine net savings.
How much can I save with solar in Pakistan?
Most households save between 60% and 90% on electricity bills, depending on system size and usage patterns.
What is the average payback period for solar in Pakistan?
Typically 3–5 years without batteries and up to 8 years with batteries.
Is net metering still worth it in 2026?
Yes, but savings are higher when you consume solar energy directly rather than exporting it.
How long do solar panels last?
Most solar panels last more than 25 years, with gradual efficiency decline over time.
Conclusion: How to Calculate Your Home Solar System Savings in Pakistan 2026
Understanding how to calculate your home solar system savings in Pakistan 2026 is essential for making a smart investment. By analyzing your usage, system size, tariffs, and net metering benefits, you can accurately estimate your return on investment. Solar remains one of the most reliable ways to reduce electricity costs and protect yourself from rising tariffs in Pakistan.
