About the Solar Payback Calculator Pakistan 2026 (5kW Pays Back in 5-7 Years)
5 kW rooftop solar pays back in 5 to 7 years and saves roughly Rs 40 lakh over 25 years on a household paying Rs 25,000 monthly bill (2026 net billing). Free Pakistan solar payback and ROI calculator. Compare vs Behbood Savings Certificate, NSC Defence Savings, bank FD and Al Meezan Islamic Money Market Fund. Inflation adjusted breakeven year and 25 year lifetime savings. Enter your system cost (typical 5 kW on grid: Rs 7 to 9 lakh), expected monthly savings after net metering (typical Rs 20 to 23k for a Rs 25k bill home), expected annual tariff inflation (default 12 percent, Pakistan historical average), and analysis horizon (default 25 years, panel warranty life). The tool gives you simple payback period, inflation adjusted payback (real timeline given electricity tariffs rise), 25 year lifetime savings, net profit after horizon, annualized return (rough IRR equivalent), AND a side by side comparison with parking the same money in Behbood Savings Certificate (16.32%), NSC Defence Savings (14.5%), conventional bank FD (13.5%), Al Meezan Islamic Money Market Fund (9.58% trailing), and Naya Pakistan Certificate (14.5%). Cash flow table shows year by year cumulative savings and the year you break even.
Total installed cost: panels + inverter + mounting + wiring + installation (and battery if hybrid). Typical 5 kW on grid: Rs 7 to 9 lakh.
Use our Solar System Size Calculator to estimate this. For Rs 25,000 monthly bill households the figure is usually Rs 20,000 to 23,000 / month after net metering.
Pakistan electricity tariff has averaged 10 to 15% annual increases since 2020. Default 12% is a reasonable mid estimate.
Tier 1 panels have 25 year linear warranty; many last 30+ years.
Note: these are nominal returns gross of withholding tax (10% for filers on most, up to 30% for non filers). Solar savings escape tax entirely because they are bill reductions, not income. Adjust returns down by 10% if you compare apples to apples.
| Year | Annual savings | Cumulative | Net position |
|---|---|---|---|
| 1 | Rs 264,000 | Rs 264,000 | Rs -536,000 |
| 3 | Rs 327,858 | Rs 886,060 | +Rs 86,060 |
| 5 | Rs 407,163 | Rs 1,658,588 | +Rs 858,588 |
| 10 | Rs 699,800 | Rs 4,509,239 | +Rs 3,709,239 |
| 15 | Rs 1,202,761 | Rs 9,408,715 | +Rs 8,608,715 |
| 20 | Rs 2,067,211 | Rs 17,829,549 | +Rs 17,029,549 |
| 25 | Rs 3,552,961 | Rs 32,302,618 | +Rs 31,502,618 |
Reality check on the IRR: this assumes you actually keep the saved money invested or use it to offset future bills. Solar also gives you protection against tariff hikes (the most likely scenario in Pakistan), zero inflation on the saving itself (a paid system keeps producing regardless of NEPRA decisions), and no withholding tax. Even at similar nominal returns, solar usually wins on a risk adjusted basis. The exception: if you would otherwise put the money in equity / Islamic equity mutual funds with 18 to 22% long term historical returns, the math tightens.
