How Our Sizing & Tariff Calculation Works

Understanding NEPRA slabs, peak vs off-peak rates, and why solar pays back faster in Pakistan than almost anywhere else in the world.

1. Unit Generation Ratio

In Pakistan's climate (Islamabad, Rawalpindi, Lahore, Multan), each 1 kilowatt (kW) of Tier-1 solar panels generates between 125 to 135 units (kWh) per month on average throughout the year.

2. Eliminating Top Slabs

WAPDA tariffs are progressive. Units above 300 and 700 are billed at Rs. 55 to Rs. 70+ per unit including fuel price adjustments (FPA) and taxes. Solar immediately eliminates your most expensive top-tier units first.

3. 3-Year Rapid Payback

Because electricity tariffs have increased substantially in Pakistan, the return on investment (ROI) is achieved in just 2.8 to 3.5 years. After payback, your power is essentially 100% free for the remaining 22 years of panel warranty!
