Lahore Solar ROI Calculator
Estimate PV payback, first-year savings, export revenue, IRR, NPV, and LCOE for a solar project in Lahore, Pakistan.
How to use this Lahore estimate
Start with the default residential assumptions, then replace them with your installer quote, roof size, self-consumption share, retail tariff, export tariff, loan terms, and expected maintenance cost. Solar economics are most sensitive to system cost, usable irradiation, electricity value, and self-use ratio.
Before trusting a result
- Check that the tariff matches the actual customer class and billing plan.
- Use a complete turnkey cost, not module price only.
- Adjust shading, soiling, thermal losses, and roof orientation.
- Review tax treatment, incentive rules, and export compensation locally.
FAQ
Can PV Yield replace a bank-grade solar financial model?
No. It is an early screening calculator. Use local engineering design, tariff confirmation, tax advice, and lender requirements before investment decisions.
Which inputs matter most in Lahore, Pakistan?
System cost, self-consumption ratio, retail electricity value, export tariff, available irradiation, shading loss, and financing terms usually drive most of the payback change.
Why are default tariffs marked as estimates?
Solar export value often varies by utility, state, province, customer class, policy year, and contract. Replace defaults with the tariff that applies to the actual site.
