How Many Solar Panels for 1.5 Ton AC in Pakistan? – Complete Guide
One of the most common questions in Pakistan is: “How many solar panels do I need to run a 1.5 ton AC?”
This is a valid question. Pakistani summers are extremely hot. Load shedding makes it worse. And solar is the best solution.
This guide will give you a clear and simple answer. No confusion. Just practical information.
Step 1: How Much Power Does a 1.5 Ton AC Use?
A 1.5 ton AC typically uses between 1200W to 1500W when running normally. However, there is something called starting surge or “inrush current.” When the compressor starts, it can draw up to 2000W for 2-3 seconds.
So your solar system must handle:
- Running power: 1200W to 1500W
- Starting power: ~2000W (temporary)
A good quality hybrid inverter can handle this surge easily. Cheap inverters may trip.
Step 2: Solar Panel Calculation Using 585W Panels
We recommend using 585W panels because they are widely available in Pakistan and offer good efficiency.
Option 1 (Basic Setup):
- 6 panels × 585W = 3510W total
- Best for: Running only the AC during daytime
- Good for: Small roofs or tight budgets
Option 2 (Recommended Setup):
- 7 panels × 585W = 4095W total
- Best for: AC + other home appliances
- Good for: Cloudy days and extra margin
Our Recommendation:
Go with 7 panels (4095W). The extra panel gives you peace of mind. On cloudy days, your AC will still work. You can also run fans, lights, and a fridge without worry.
Step 3: Why 585W Panels?
585W panels are now standard in Pakistan. They provide more power in less space.
| Panel Type | Wattage | Space Required |
|---|---|---|
| 585W Mono PERC | 585W per panel | ~2.2 sq meters per panel |
| 6 panels | 3510W | ~13 sq meters |
| 7 panels | 4095W | ~15 sq meters |
Most Pakistani rooftops can easily fit 7 panels.
Step 4: What About the Inverter?
You need a hybrid solar inverter that can handle the starting surge of the AC.
| Inverter Size | Suitable For |
|---|---|
| 3.5kW to 5kW | 6 panels (3510W) – basic setup |
| 5kW to 6kW | 7 panels (4095W) – recommended |
A 5kW hybrid inverter is the best choice. It gives you room for future expansion.
This calculation is for daytime use only.
- Without battery: AC runs only when the sun is shining.
- With battery: AC runs at night too, but you need a large battery bank.
If you want night backup:
- Lithium battery: 5kWh to 7kWh
- Lead acid battery: 200Ah to 300Ah at 48V
Lithium batteries are expensive but last longer and need less maintenance.

Summary Table – Quick Decision
| Setup | Panels | Total Power | Best For |
|---|---|---|---|
| Basic | 6 × 585W | 3510W | Only AC during daytime |
| Recommended | 7 × 585W | 4095W | AC + other appliances |
| With Battery | 7 panels + 5kWh lithium | 4095W | AC day + night backup |
Final Tips
- Always keep a margin. Pakistani weather is unpredictable. Extra panels help on cloudy days.
- Buy from a trusted shop. Avoid online-only sellers with no physical location.
- Use a good inverter. Don’t compromise on the inverter. It is the brain of your system.
- Clean panels regularly. Dust reduces power output by 20-30%.
