Solar Cost Calculator
Estimate the complete cost of a solar system in Pakistan — panels, inverter, battery and installation.
About the Solar Cost Calculator
The Solar Cost Calculator is a free, private tool that runs entirely in your browser — your inputs never leave your device, and the answer appears the instant you enter them.
Solar power is one of the largest one-time expenses a Pakistani household will make — and also one of the best-returning ones given rising electricity tariffs. This Solar Cost Calculator estimates the full installed cost of a solar system from its size in kW, using current per-watt pricing for panels, inverters, batteries and installation.
The calculation multiplies the system size by realistic per-watt rates for each component, giving a transparent breakdown instead of a single opaque quote. Seeing the panel, inverter and battery line items separately helps you spot where a quote is inflated.
Prices in Pakistan vary with brand and quality: Tier-1 panels, hybrid inverters and lithium batteries cost more upfront but last longer and perform better. The calculator's rates are editable so you can model a budget, mid-range or premium configuration.
Before signing, compare at least three installer quotes against this estimate. A quote significantly below it may use sub-standard equipment; one far above it may include excessive margin. The tool gives you the honest benchmark.
Come back to the Solar Cost Calculator whenever your numbers change; because everything runs live in your browser, you can re-run it as many times as you need at no cost.
How to estimate solar installation cost
- 1
Enter the system size in kilowatts (from your solar sizing calculation).
- 2
Adjust the per-watt rates for panels, inverter and batteries if you have quotes.
- 3
Read the component-by-component cost and total installed price.
- 4
Compare the total with installer quotes before committing.
Frequently Asked Questions
What is the cost of solar per watt in Pakistan?
On-grid systems run about Rs 130–160 per watt installed in 2025; hybrids with lithium batteries add Rs 50,000–80,000 per kWh of storage. A 5 kW on-grid system is roughly Rs 700,000–900,000.
What is the per-watt cost of solar in Pakistan?
In 2025, installed costs typically range Rs 150–250 per watt depending on panel brand, inverter type and whether batteries are included. The calculator's rates are editable to match your quote.
Are lithium batteries worth the extra cost?
Lithium batteries last 2–3× longer than lead-acid and tolerate deeper discharge, so over their lifetime they are often cheaper per cycle — especially with daily cycling in a hybrid system.
