Is Solar Worth It in Pakistan in 2026?
This is the question every homeowner asks before committing to solar. The answer used to be simple: yes, always. In 2026, after NEPRA’s shift from net metering to net billing, the answer requires more nuance. It depends on your bill size, system type, and how you use electricity. Here is the honest math.
What Changed: Net Metering vs Net Billing
Under the old net metering rules, every unit you exported to the grid was credited at the full retail rate. Export 500 units, save 500 units worth of charges. The economics were straightforward and extremely favourable.
Under NEPRA’s 2026 net billing rules, exported units are now credited at approximately Rs. 11 per unit. Imported units still cost Rs. 48-65 per unit depending on your slab. Self-consumed solar still saves the full retail rate. Only the value of surplus exports has dropped.
This means system sizing and self-consumption now matter more than total generation. A well-designed system that matches your daytime load still delivers excellent returns. An oversized system that exports most of its generation delivers weaker returns than before.
The Math: High Bill Scenario
Monthly bill: PKR 40,000-60,000 (600-900 units consumed)
A 10kW on-grid system costs PKR 14-18 Lakh and generates approximately 1,300 units per month. With a high bill, daytime consumption is substantial. Self-consumption ratio: 60-70%. Surplus export: 30-40%.
| Metric | Value |
|---|---|
| Monthly generation | 1,300 units |
| Self-consumed (65%) | 845 units x Rs. 55 = Rs. 46,475 saved |
| Exported (35%) | 455 units x Rs. 11 = Rs. 5,005 credited |
| Total monthly value | Rs. 51,480 |
| System cost | Rs. 16 Lakh |
| Payback period | 31 months (under 2.5 years) |
Verdict: Solar is overwhelmingly worth it. The payback is under 3 years, and the system produces free electricity for 22+ more years.
The Math: Medium Bill Scenario
Monthly bill: PKR 15,000-25,000 (250-400 units consumed)
A 5kW on-grid system costs PKR 7.5-9.5 Lakh and generates approximately 650 units per month. With moderate consumption, self-consumption ratio: 50-60%. Surplus export: 40-50%.
| Metric | Value |
|---|---|
| Monthly generation | 650 units |
| Self-consumed (55%) | 358 units x Rs. 50 = Rs. 17,875 saved |
| Exported (45%) | 293 units x Rs. 11 = Rs. 3,223 credited |
| Total monthly value | Rs. 21,098 |
| System cost | Rs. 8.5 Lakh |
| Payback period | 40 months (under 3.5 years) |
Verdict: Still worth it. Payback under 4 years with 21+ years of free electricity remaining. The lower self-consumption ratio reduces returns compared to the high-bill scenario, but the investment is still strong.
The Math: Low Bill Scenario
Monthly bill: PKR 5,000-10,000 (under 200 units consumed)
A 3kW on-grid system costs PKR 5-6.5 Lakh and generates approximately 390 units per month. With low consumption, self-consumption ratio: 35-45%. Surplus export: 55-65%.
| Metric | Value |
|---|---|
| Monthly generation | 390 units |
| Self-consumed (40%) | 156 units x Rs. 40 = Rs. 6,240 saved |
| Exported (60%) | 234 units x Rs. 11 = Rs. 2,574 credited |
| Total monthly value | Rs. 8,814 |
| System cost | Rs. 5.75 Lakh |
| Payback period | 65 months (under 5.5 years) |
Verdict: Marginal. The payback period stretches to 5+ years. Still profitable over the system’s lifetime, but the returns are significantly weaker. For bills under PKR 10,000, consider whether the capital is better deployed elsewhere, or size the system smaller to maximise self-consumption ratio.
On-Grid vs Hybrid: Impact on Returns
Hybrid systems cost PKR 3.5-8 Lakh more than equivalent on-grid systems due to battery costs. But under net billing, storing surplus in batteries (instead of exporting at Rs. 11) is now more valuable. Every stored unit used at night saves Rs. 37-54 more than exporting it.
For households with significant nighttime consumption (ACs, lighting) or frequent load shedding, hybrid systems can deliver stronger total savings despite the higher upfront cost. See our on-grid vs hybrid comparison for the full breakdown.
Factors That Improve Returns
• Shift loads to daytime. Run washing machines, water pumps, dishwashers, and water heaters during peak solar hours. Every unit you self-consume instead of exporting is worth Rs. 37-54 more.
• Proper system sizing. A system matched to your daytime load delivers better returns than an oversized system. SOL AI helps optimise load timing after installation.
• Rising tariffs. Pakistan’s electricity tariffs have increased every year for the past decade. Your solar savings grow as tariffs rise. A system that saves Rs. 50,000/month today will save more next year.
• Solar tax credit. Accelerated depreciation on solar assets is available for commercial and industrial installations, improving after-tax returns.
When Solar Is NOT Worth It
• Bills under PKR 5,000/month. At this consumption level, the system is too small to justify the fixed costs of installation, net metering application, and monitoring. Returns are thin.
• Heavy shading. If your roof is mostly shaded by adjacent buildings or trees and cannot be cleared, generation will be too low for viable returns. A proper site survey identifies this upfront.
• Rented property without long tenure. If you are renting and your lease is under 3 years, you may not recoup the investment before moving. However, some landlords split costs in exchange for lower rent or property value improvement.
The Bottom Line
For monthly electricity bills above PKR 15,000, solar is worth it in 2026. The payback is 2-4 years depending on system size and self-consumption ratio. After payback, every unit is free for 20+ years. Rising tariffs make the value proposition stronger every year.
The NEPRA net billing changes reduced the value of surplus exports but did not change the value of self-consumed solar. A properly sized system, installed by a competent EPC company, and monitored for ongoing performance, remains one of the best investments a Pakistani homeowner or business can make.
