How Many Solar Panels Do You Need For a 1.5 Ton AC? | Easy Solar Power Calculation
With the cost of energy going up and environmental concerns for the planet growing, more and more people are trying to find ways to power their homes using renewable energy sources. A common question among homeowners is how many solar panels required for 1.5 ton ac to ensure efficient cooling while keeping energy consumption sustainable.
Air conditioners, especially in the hot summer months, consume a lot of electricity. So, if you’re thinking about using solar panels to power your 1.5-ton AC, then you have made the right choice.

Inverter vs non-inverter AC
Inverter AC: The inverter AC changes compressor speed to maintain a constant room temperature. Once the desired temperature is reached, it operates at a lower speed, consuming less energy over time. This makes inverter ACs more energy efficient and cost effective in the long term.
Non-inverter AC: A non-inverter AC operates by alternating between running and idle modes, turning off and on as needed. The compressor operates at full power to cool the space and then turns off completely when the required temperature is reached. It resumes as the room temperature rises, resulting in increased energy use and variable room temperatures.
AC power consumption comparison in Pakistan
| Type of AC | Power Consumption (Watts) |
| 1-ton AC (non-inverter) | 1500W |
| 1-ton inverter AC | 900W |
| 1.5-ton AC (non-inverter) | 2000W |
| 1.5-ton inverter AC | 1200W |
| 2-ton AC (non-inverter) | 2500W |
| 2-ton inverter AC | 1500W |
How many units of electricity does my 1.5-ton AC consume?
In order to calculate your daily kWh usage of your AC, you have to know the energy consumption of the AC first. Check out the table above to get an idea of your AC power consumption.
For example, A 1.5-ton non-inverter AC consumes 2000W.
Divide the wattage by 1000 to convert it to kilowatts, i.e 2000/1000 = 2kW
Multiply the kW value by the number of hours the AC runs. Suppose your AC runs 6 hours a day, 2kW × 6 hours = 12 kWh or units per day.

How many solar panels do I need for a 1.5-ton AC?
Before determining how many solar panels are needed for an AC, we first need to know about the daily kWh usage. Use the details above to calculate the electricity consumption of your 1.5-ton AC. Based on this, you can then determine the required size of the solar system and the number of panels needed to meet that requirement.
Look up the table below for a detailed estimated overview of a 1.5-ton AC (non-inverter).
| Number of hours used per day | kWh / number of units | The best solar system size for the appliance | Number of solar panels required (Assuming 575W panels) |
| 4 hours | 8kWh | 8-10kW | 18 panels |
| 6 hours | 12kWh | 15kW | 24-26 panels |
| 8 hours | 16kWh | 20-25kW | 42-44 panels |
Can I Run AC Directly on a Solar Panel?
An AC cannot be run directly by solar panels without extra equipment. Here’s why:
DC to AC Conversion
Solar panels produce direct current (DC), while air conditioners run on alternating current (AC). To convert DC from solar panels into AC, you will need an inverter.
Battery Storage
Solar panels work only during sunlight hours. So, if you want to use AC at night or on cloudy days, you’ll need batteries to store up the extra solar energy you make during the day.
Power Stability
AC needs a constant supply of electricity. Solar electricity may not be enough to keep your air conditioner functioning smoothly. Combining solar panels, inverters, and batteries will ensure that your air conditioner always has power. This way, you’ll have a backup power source in case sunlight isn’t available.
Conclusion
Turning to solar energy for air conditioning helps reduce energy use and benefits the environment. In Pakistan, the number of solar panels you need for an AC depends on how much you use it. Keep in mind that you can’t run an AC directly from solar panels without using an inverter and battery system.
