Planning to install solar panels but not sure how large a system is required? Our Solar Calculator Pakistan helps estimate the solar system capacity based on electricity consumption, monthly units, panel wattage, and system type.
Enter your electricity usage and select your preferred solar panel options to get an estimated solar system size, number of panels, daily generation, monthly generation, inverter capacity, and approximate system cost. The calculate is designed to give Pakistani homeowners and businesses a quick starting point before requesting a detailed quotation from a solar installer.
Solar system size & cost calculator
Enter your monthly electricity bill or units, and this calculator will show your recommended solar system size, inverter, panels, cost, battery backup, financing, and roof space requirement based on average sunlight and current market rates in Pakistan.
1. Your electricity usage
Use whichever you know your bill amount or your units consumed.
2. Net metering (optional)
If you export extra units to the grid, NEPRA’s net metering credits them at a buyback rate. Applies to on-grid and hybrid systems.
3. Battery backup
Size a lithium battery for essential loads during a power outage.
4. Financing / installment estimate
A rough EMI estimate if you plan to finance instead of paying cash.
5. Roof space check
Confirm your roof can fit the recommended system. Each panel needs roughly 27 sq ft including mounting spacing.
6. Save this estimate or request a quote
Send your details and our team will reach out to arrange a free site survey.
This is a rough estimate for guidance only. Roof orientation, shading, actual DISCO buyback rates, and a site survey by a local installer may change the final numbers — contact our team for a final quotation.
How Does the Solar Calculator Work?
Our Solar Calculator Pakistan uses your electricity consumption to provide an initial estimate of the solar system you may need. You can enter your monthly electricity units, select your location, choose a panel wattage, and select the type of solar system you are interested in.
The calculator then estimates the required system capacity, number of solar panels, expected electricity generation, inverter size, and approximate system cost.
For example, if a household uses around 600 units per month, its average daily consumption would be approximately:
600 ÷ 30 = 20 units per day
How Many Solar Panels Will You Need?
Once the required system size is estimated, the number of panels depends mainly on the wattage of the selected solar panel.
For example, a 5kW solar system with 600W panels would require approximately:
5,000W ÷ 600W = 8.33 panels

| Solar System | 550W Panels | 580W Panels | 600W Panels | 650W Panels |
|---|---|---|---|---|
| 3kW | 6 | 6 | 5 | 5 |
| 5kW | 10 | 9 | 9 | 8 |
| 6kW | 11 | 11 | 10 | 10 |
| 8kW | 15 | 14 | 14 | 13 |
| 10kW | 19 | 18 | 17 | 16 |
| 15kW | 28 | 26 | 25 | 24 |
| 20kW | 37 | 35 | 34 | 31 |
