Calculation Assumptions
The calculations are based on the following assumptions:
- Panel efficiency: 20% (adjusted for shading)
- System derate factor: 0.85
- Performance ratio: 0.80
- Electricity tariff: ₨62 per kWh
- System cost: ₨150,000 per kW
- CO₂ reduction: 0.7 kg per kWh
- Roof area conversion: 1 sq ft = 0.0929 sq m
These values are estimates and actual results may vary based on specific conditions.
Calculate Your Monthly & Yearly Savings
Another bill shock? If your last electricity bill made you gasp, you’re not alone. NEPRA has raised tariffs five times in 24 months, pushing the average residential rate past PKR 48 per unit in 2024. For a medium-sized home using 700 kWh a month, that’s PKR 33,600 every bill—before fuel surcharges. The good news? Rooftop solar can cut this cost by 40 – 90 %. Our solar savings calculator Pakistan shows exactly how much you can save, how fast the system pays for itself, and what it will cost to install—all in one simple screen.
How the Solar Savings Calculator Works
Your Inputs (takes 20 seconds)
- Monthly electricity bill (PKR)
- City or nearest major location
- Available roof area or “auto-size” option
Assumptions We Use (transparent and adjustable)
- Average sunlight hours: 5.4 in Karachi, 5.8 in Lahore, 5.2 in Islamabad (source: NREL)
- Panel efficiency: 20 % monocrystalline
- Grid tariff: PKR 48 / kWh (latest NEPRA slab)
- Net-metering sell-back rate: PKR 19 / kWh (DISCO average)
- Annual panel degradation: 0.5 %
Instant Outputs

Benefits of Going Solar in Pakistan
Slash Your Bills
A 5 kW system on a PKR 30,000 monthly bill typically saves PKR 22,000 every month—PKR 264,000 per year.
Energy Independence
Solar plus net-metering means you sell excess units back to the grid and buy zero during peak hours.
Rising Tariff Shield
Every time NEPRA raises tariffs, your solar ROI improves. Your locked-in solar rate never changes.
Green Impact
Each 5 kW system offsets 4.2 tons of CO₂ annually—equal to planting 190 mature trees.
Frequently Asked Questions
Q1. How much money can I save with solar panels in Pakistan?
Most households save between PKR 1 million and 1.8 million over 10 years, depending on system size and bill.
Q2. What is the average payback period?
Residential systems installed in 2023 are paying back in 3.2 – 4.5 years thanks to falling panel prices and improved net-metering.
Q3. How accurate is this calculator?
Variance is ±5 % when roof orientation and shading are entered correctly. We update tariffs every quarter.
Q4. What factors affect my solar savings the most?
Roof direction (south-facing is best), shading, panel quality, inverter efficiency, and future tariff hikes.
Q5. Does the calculator include financing options?
Yes. Tick the “Financing” box to see monthly instalments for 3-, 5-, or 7-year bank plans.
