How Many Solar Panels Do You Need to Run an AC in Pakistan? (2026 Guide)
In Pakistan’s brutal summers, the air conditioner is the single biggest reason your electricity bill explodes — and the first thing people want to run on solar. The great news: yes, you can run your AC on solar. The question everyone asks is simply, “how many solar panels do I need?”
Here is a clear 2026 guide from Abu Bakar Solar Kohat (ABS Kohat).
First: Inverter AC vs Non-Inverter AC
This matters a lot. An inverter (DC) AC uses far less electricity than an old non-inverter unit — often 30–50% less — because it varies its speed instead of switching fully on and off. If you are buying an AC to pair with solar, always choose an inverter AC. It needs fewer panels and a smaller battery.
How Many Solar Panels to Run an AC?
As a practical guide for Pakistan (using modern ~500–585W panels):
| Air Conditioner | Solar System Size | Approx. Panels |
|---|---|---|
| 1 Ton Inverter AC | ~2.5–3 kW | 5–6 panels |
| 1.5 Ton Inverter AC | ~3.3–5.5 kW | 6–8 panels |
| 2 Ton Inverter AC | ~5–6 kW | 9–11 panels |
Do You Need a Battery to Run AC at Night?
During daylight, panels can power your AC directly. To run the AC at night or during load-shedding, you need a lithium battery to store daytime solar:
- A few hours of night cooling: ~5–10 kWh lithium battery
- 6–8 hours overnight on a 1.5-ton AC: ~10–15 kWh battery bank
Lithium (LiFePO4) is strongly recommended here — see lithium vs lead-acid to understand why.
Running More Than One AC
For two or more ACs plus other appliances, most homes move to a 6–10 kW hybrid system with a larger battery. Our team can size this precisely based on how many ACs you run and for how long.
What Does It Cost?
| Setup | Approx. Cost (2026) |
|---|---|
| 5 kW system (runs 1.5-ton AC + home), no battery | ~Rs 600,000–750,000 |
| 5 kW system + 5 kWh lithium battery | ~Rs 850,000–1,000,000 |
Costs vary with panel and battery brands. Panel prices are near record lows right now, making this a great time to add solar for your AC.

Recommended Setup
- Daytime cooling only (office/shop): a day-time inverter + panels — cheapest option, runs the AC on sunshine.
- 24/7 cooling + backup: a hybrid inverter + panels + lithium battery.
Frequently Asked Questions
How many solar panels are needed for a 1.5 ton AC in Pakistan?
Around 6–8 modern panels (a 3.3–5.5 kW system) will run a 1.5-ton inverter AC during the day along with basic home appliances. Non-inverter ACs need more.
Can I run my AC on solar without a battery?
Yes — during daylight hours, panels can power your AC directly. You only need a battery if you want to run the AC at night or during load-shedding.
What size battery do I need to run an AC at night?
Roughly a 5–10 kWh lithium battery for a few hours, or 10–15 kWh to run a 1.5-ton inverter AC for 6–8 hours overnight.
Is an inverter AC better for solar?
Definitely. Inverter ACs use significantly less electricity, so they need fewer panels and a smaller battery than non-inverter units.
