Pakistan Solar Payback Calculator
Free Pakistan solar payback calculator — estimate annual savings and the payback period for a solar system from cost, generation and tariff, in Rs.
About the Pakistan Solar Payback Calculator
With rising electricity tariffs, solar is an increasingly popular investment in Pakistan — but is it worth it for you? This free solar payback calculator estimates your annual savings and how many years it takes to recover the system cost, based on generation, the unit tariff and expected tariff escalation.
All inputs are editable so you can model net metering, different system sizes and future tariff increases. Results are in rupees and calculated instantly in your browser, with no signup.
How to Use the Pakistan Solar Payback Calculator
- 1Enter the total system cost and expected annual generation.
- 2Set your electricity tariff per unit and yearly escalation.
- 3Review the estimated annual savings.
- 4See the payback period in years, then adjust the inputs.
Frequently Asked Questions
How is the payback period calculated?
The tool divides your system cost by the annual savings from self-generated electricity, factoring in tariff escalation so later savings are larger. The result is the number of years to break even.
Does it account for net metering?
You can reflect net metering by entering the generation and effective tariff you receive for exported units, since net-metering rules and buy-back rates vary.
What generation figure should I use?
In much of Pakistan, roughly 1,400–1,600 units per kW per year is typical, but it depends on location, panel orientation and shading. Use a local estimate for accuracy.
Is this a guaranteed return?
No. It is a planning estimate. Real savings depend on future tariffs, system performance and maintenance, so treat the payback as indicative.
