What you get from a solar estimate

A proper solar estimate answers four questions before you ever speak to an installer: how big a system do I need, how much will it cost, how much will it save me, and when does it pay for itself? SolarEstimateOnline returns all four — plus a 25-year savings projection, a CO₂ offset figure, and a battery sizing recommendation if you need backup.

Why an online solar estimate is the right starting point

Most solar installers in Pakistan offer free site surveys, but they also lead to high-pressure quotes. An online solar estimate gives you an independent baseline before any installer shows up. If the installer's quote is within 10–15% of your estimate, you're being offered fair-market pricing. If it's 30% higher, you have grounds to negotiate or shop around.

How to get an accurate solar estimate

For the most accurate solar estimate, use a recent summer bill (June, July or August) rather than a winter one. Summer bills capture peak AC load, which is what your solar system actually needs to offset. If you only have a winter bill, multiply units by ~1.6 to approximate your summer consumption before entering it.

Three other inputs make a big difference: your city (sets local sun hours), your backup requirement (sets battery sizing), and your roof size (validates whether the recommended panel count physically fits).

Solar panel estimate, system size, and battery sizing

The estimate breaks down into a complete solar panel estimate: kW system size, exact panel count at 550 W per panel, total roof space needed in sq ft, and — if you've selected essentials or full-day backup — a recommended battery capacity in kWh with installed cost. You can change the backup mode on the form to see how it shifts your total upfront cost and payback period.

Bill upload supported for every Pakistani utility

The bill parser handles PDF statements from every DISCO in Pakistan — K-Electric, LESCO, IESCO, MEPCO, FESCO, HESCO, QESCO, GEPCO, SEPCO, PESCO. It pulls out monthly units and total bill amount, you confirm the read on a pre-filled form, and the estimate runs. Don't have a PDF? Use the manual tab and enter the same two numbers from any month's printed bill.

Solar estimate FAQs

How does the solar estimate calculator work?
Enter your monthly electricity bill, units consumed (kWh), and city — or upload a WAPDA / K-Electric / IESCO / LESCO bill PDF. The calculator sizes a solar system that offsets your usage based on local peak sun hours, applies current installed costs in PKR, and projects savings against your tariff slab. Results include system size in kW, panel count, monthly savings, and payback years.
Is the solar calculator free to use?
Yes. SolarEstimateOnline is a free solar calculator for Pakistan. There is no signup, no email gate, and no callback from sales reps. Every calculation runs in your browser — your bill data never leaves your device.
How accurate is the solar estimate?
The estimate is accurate within roughly ±10% for residential systems. We use NEPRA-published tariff slabs, average per-city peak sun hours, and current installed system costs from Pakistan's solar market. For a binding quote you still need an on-site survey, but the calculator is designed to be within range of real installer proposals.
What is net metering in Pakistan and how does it affect savings?
Net metering lets you export surplus solar generation back to your DISCO and receive credit at NEPRA's notified buyback rate (currently around PKR 10/unit for new connections). The calculator factors this in when sizing your system — oversizing beyond your usage gives diminishing returns under the new tariff.
What size solar system do I need for my home in Pakistan?
Most residential homes in Pakistan need a 5kW to 10kW system. A 5kW system covers bills around PKR 25,000–40,000 and 1–2 ACs. A 10kW system covers bills of PKR 50,000+ and 3–4 ACs. The exact size depends on your monthly units, roof orientation, and whether you want a battery for load-shedding.
What information from my electricity bill is needed?
Two numbers: total units consumed (kWh) and total bill amount in PKR. Upload your bill PDF and the calculator reads both automatically. Or enter them manually from any month's bill — pick a recent summer bill for the most accurate estimate.
Does the calculator work with WAPDA bills?
Yes. The calculator works with bills from every Pakistani DISCO that issues WAPDA-style bills — LESCO, IESCO, MEPCO, FESCO, HESCO, QESCO, GEPCO, SEPCO, PESCO — and also K-Electric. Both PDF and image formats are supported.
