Solar Panel Cost Calculator Pakistan
Estimate the total cost of installing a solar panel system for your home or business. Enter your monthly electricity consumption, select system size, and see panel costs, inverter, battery, and installation charges based on 2026 market rates.
Introduction
With rising electricity tariffs in Pakistan, many households and businesses are turning to solar energy to reduce their monthly bills. The upfront cost of a solar system depends on the size (in kilowatts), the number of panels, inverter type, battery backup, and installation charges. Solar panel prices in Pakistan have been volatile in 2026, with fluctuations driven by tax policy uncertainty and international prices [citation:4][citation:11].
What is this calculator?
The Solar Panel Cost Calculator Pakistan estimates the total cost of installing a solar system based on your monthly electricity consumption. It calculates the required system size (kW), number of panels, inverter cost, battery cost (if any), and installation charges.
How the calculation works
The calculator converts your monthly units (kWh) to daily consumption, then determines the solar system size needed based on average peak sun hours in Pakistan (approximately 4-5 hours). It then estimates component costs.
Formula
Daily Consumption (kWh) = Monthly Units ÷ 30
System Size (kW) = Daily Consumption ÷ 4.5 (peak sun hours)
Number of Panels = System Size (kW) × 1000 ÷ Panel Wattage
Total Cost = Panels + Inverter + Battery + Installation + Wiring
Important terms
- kW (Kilowatt)： System size — 1 kW system produces about 4-5 units per day in Pakistan.
- Panel Wattage： Common panels in Pakistan are 585W, 645W, and 720W [citation:4].
- On-Grid System： Connected to WAPDA/K-Electric, no battery backup, lower cost.
- Off-Grid System： With battery backup, higher cost, works during load-shedding.
- Hybrid System： Combination of on-grid and battery backup.
How to use the calculator
- Enter your monthly electricity consumption (units from your bill).
- Select system type (On-Grid, Off-Grid, or Hybrid).
- Select panel wattage (585W, 645W, 720W).
- Click Calculate Solar Cost.
Practical Pakistan-specific example
Example： Household consuming 500 units/month, 5kW on-grid system with 585W panels
- Daily consumption = 500 ÷ 30 = 16.67 kWh
- System size = 16.67 ÷ 4.5 = 3.7 kW (rounded to 4kW)
- Panels needed = 4000 ÷ 585 = 7 panels
- Panel cost (Rs 28,000 each) = Rs 196,000
- Inverter (5kW) = Rs 150,000
- Installation and wiring = Rs 50,000
- Total Cost ≈ Rs 396,000 (on-grid, no battery)
Factors affecting the result
- System type： Off-grid with battery costs significantly more than on-grid.
- Panel prices： Solar panel prices have been volatile in 2026 due to tax uncertainty [citation:4].
- Net metering： On-grid systems can sell excess electricity back to the grid, reducing payback period.
- Installation quality： Cheaper installation may compromise safety and efficiency.
Common mistakes
- Under-sizing the system based on peak consumption instead of average.
- Ignoring battery replacement costs (every 5-7 years).
- Not checking net metering availability with your DISCO.
- Buying panels without verifying warranty and certification.
Who can use the calculator
- Homeowners： Planning to install solar to reduce bills.
- Business owners： Calculating ROI for commercial solar.
- Solar installers： Estimating project costs for clients.
