Home Solar Calculator
Select your ACs and system type — get an instant estimate. Faisalabad averages 6.5+ peak sun hours in summer.
Run your ACs all day during sun hours — cold home, no guilt. Faisalabad gets 6.5+ peak sun hours in summer — that's 6–8 hours of free, uninterrupted AC every day. A genuine gift for the elderly and housewives this summer.
How the Calculator Works
Select Number of ACs
Pick how many air conditioners you want to run comfortably during daytime. This is the biggest driver of system size — one 1.5-ton inverter AC draws 1.2–1.5 kW/hour. Your WAPDA bill shows consumption but your actual load determines the inverter size needed.
Choose System Type
Hybrid with battery (recommended): runs ACs all day + covers load-shedding. Hybrid without battery: lower upfront cost, add battery later with no rewiring. On-grid: cheapest, maximum bill savings, but shuts off during load-shedding — no backup.
Get Your Instant Estimate
The calculator outputs recommended kW size, panel count, estimated monthly saving, and system cost using 2026 Faisalabad market prices and 6.5 peak sun hours (summer average). Takes 5 seconds.

| Typical Home | System Size | Panels (650W) | Est. Monthly Production | Hybrid Cost — Live | Est. Annual Saving |

* For hybrid systems, inverter capacity must cover peak simultaneous load — not just production. 1–2 ACs: 6 kW inverter · 3 ACs: 8 kW · 4–5 ACs: 10–12 kW.
What Affects Your Solar System Size?
Air Conditioner Tonnage
A 1.5-ton inverter AC consumes approximately 1.2–1.5 kW/hour. Running 3 ACs for 10 hours adds 36–45 kWh/day — the biggest driver of system size for Pakistani homes.
Roof Orientation & Shading
South-facing roofs with no shading deliver maximum output. East/west-facing roofs produce 15–20% less. Shading from trees or water tanks reduces output significantly.
Battery vs. No Battery
Without a battery, your solar saves on daytime bills only — grid powers you at night and during load-shedding. A 5–10 kWh battery covers 4–6 hours of load-shedding and stores solar for evening use, pushing annual savings from ~35% to ~55% of your bill.
Large Battery — Is It Worth It?
For areas with 8–12 hours of load-shedding, a 10–20 kWh battery bank covers the full outage and stores surplus for the next morning. The additional cost (Rs. 200–400K) typically adds 1–2 years to payback but gives complete energy independence.
