Understanding A 1.5 Ton Ac: “How Much Energy Does A 1.5 Ton Ac Use?”
A 1.5 ton air conditioner is a strong cooling machine. It gives around 18,000 BTU per hour. This is the cooling power. It is good for rooms like bedrooms, small halls, or offices.
Now let’s talk about power use. A 1.5 ton AC takes different units of electricity, based on the type. If the AC is a 5-star inverter, it uses less power. Around 1.5 kilowatts (kW). If the AC is old or non-inverter, it uses more power. Around 2.4 kilowatts (kW).
How much power in a full day? If you run the AC for 8 hours, a 1.5 kW AC will use around 12 units. That is 12 kilowatt-hours (kWh). If it is a 2.4 kW AC, it will use more.
Knowing this is very important. It helps in planning how many panels you need. Many people search how much solar panel required for 1.5 ton AC, but they do not know the power use. This is the first step.
Now you understand how much power a 1.5 ton AC needs in one day.
Calculating Solar Needs: “How Much Solar Panel Required For 1.5 Ton Ac”
Now let’s find out how many solar panels you need. Many people ask how much solar panel required for 1.5 ton AC, but the answer depends on some numbers.
Know Your Daily Use
A 1.5 ton AC runs for 8 hours a day. It uses about 12 units of power. That means 12 kilowatt-hours (kWh) every day.
Know Your Solar Panel Power
Each solar panel gives power in watts (W). Many panels are 350 watts. Some are more. You also need to know the sunlight hours in your area. In many places, you get around 5 hours of good sun each day.
Use The Simple Formula
You can now use this easy math:
AC power use ÷ (Panel power × Sunlight hours)
Example:
12 kWh ÷ (350 W × 5 h) = 12,000 ÷ 1,750 = Around 7 panels
So you need about 7 solar panels if each one is 350 watts.
If your panel is 300 watts, you may need more panels. If you use your AC longer, you will need more too.
This is the simple way to know how much solar panel required for 1.5 ton AC.

So the answer to how much solar panel required for 1.5 ton AC depends on panel size. Bigger the panel, smaller the number.
Factors That Influence Your Calculation
Many things affect the answer to how much solar panel required for 1.5 ton AC. You must check these things before buying panels:
AC Star Rating and Inverter
A 5-star inverter AC uses less power. It saves energy. A 1-star AC uses more power. The better the star rating, the fewer panels you will need.
Sunlight Hours
In Pakistan, most areas get about 5 hours of good sunlight each day. This is called peak sun hours. If your area gets less sun, you will need more panels. If your area gets more sun, you will need fewer.
System Losses
Solar systems lose some power. Wires, heat, and inverter cause loss. Shade on the panel also reduces power. You can lose 10% to 20% of power. So always plan a little extra.
Panel Type And Quality
Not all panels are the same. Good panels give more power. Some types are:
- Mono panels – more power, work well in heat
- Poly panels – cheaper, but less power
- PERC panels – better light capture
- Bifacial panels – take sunlight from both sides
Good panels help you use fewer units and give better results.
So when asking how much solar panel required for 1.5 ton AC, also think about these factors. They change the final number of panels you need.
Battery & Inverter Considerations
If you want to run your AC at night or on cloudy days, you need batteries. Panels only work when the sun is out. At night, power comes from the battery.
Battery Size
For a 1.5 ton AC, you need at least 150 Ah battery. If you want more backup time, use more batteries. The bigger the battery, the longer your AC can run.
Off-Grid and Grid-Tied Systems
- Off-grid system works alone. It needs battery backup.
- Grid-tied system connects with the electric line. It gives extra power back to the grid. This is called net metering. You save money this way.
If you live in a place with no power cuts, grid-tied is better. If you face power cuts, off-grid is helpful.
Inverter Size
The inverter changes solar energy into AC power for your home. The inverter must be strong. It should be 20% to 30% bigger than your AC’s top load. If your AC uses 2 kW, use a 2.5 to 3 kW inverter.
People often ask how much solar panel required for 1.5 ton AC, but forget to check battery and inverter size. These are just as important.
System Configuration & Cost Insights
To run a 1.5 ton AC, you need a solar system that gives the right power. Many people search how much solar panel required for 1.5 ton AC, but also want to know the cost and system setup.
System Size Examples
Here are two common system setups:
- 4 kW system – You can use around 6 panels of 600 watts This system can run the AC plus other items.
- 3 kW system – This setup is smaller. It can run the AC only during the day, when the sun is strong.
If you run your AC for 8 to 10 hours in the day, both setups can work. If you want to run it at night, you need batteries.
Solar Setup Cost In Pakistan
Prices may change, but here is a rough idea:
- Solar panels – Around PKR 215,000
- Battery and inverter – Around PKR 400,000 to 550,000
This is for good quality parts. Prices may go up or down depending on brand and power size.
So when you plan based on how much solar panel required for 1.5 ton AC, also plan your total budget. The right system helps save money in the long run.
