Understanding the Power Consumption of a 1.5 Ton AC
To determine how many solar plates required for 1.5 ton ac, the first step is to understand how much electricity your 1.5 ton AC consumes.
A 1.5-ton AC is designed to cool medium-sized rooms and typically requires between 1200 and 1500 watts (W) to operate. However, the actual power consumption depends on several factors, such as the type of AC (inverter or non-inverter) and the energy efficiency rating (EER). Let’s understand it to know how many solar panels required for 1.5 ton AC.
- Inverter ACs: These are energy-efficient and adjust their power consumption based on the cooling needs of the room. A typical 1.5 ton inverter AC consumes between 1200 and 1400 watts.
- Non-Inverter ACs: These consume more electricity as they run at full capacity, regardless of the cooling requirements. A 1.5 ton non-inverter AC may consume 2000 to 2500 watts during peak usage.
To put things into perspective, the cooling capacity of a 1.5-ton AC is measured in British Thermal Units (BTU). A 1.5-ton AC has a cooling capacity of 18,000 BTU, which is sufficient to cool a room of around 150-180 square feet.
Summary Table:
| AC Type | Power Consumption (Watts) | Cooling Capacity (BTU) |
|---|---|---|
| Inverter AC | 1200 – 1400 W | 18,000 BTU |

How to Calculate the Number of Solar Panels Required for a 1.5 Ton AC
Once you know the power consumption, the next step is to figure out how many solar panels are required for 1.5-ton ac.
Solar panels come in different sizes and capacities. The most common solar panel sizes used in Pakistan are 250W, 300W, and 400W. The power generated by each solar panel for AC depends on the amount of sunlight it receives. In Pakistan, where the average daily sunlight is around 5-6 hours in most regions, solar panels can generate substantial power.
The basic formula to calculate the number of solar panels required is:
Number of Solar Panels = Total Power Consumption ÷ Solar Panel Wattage
Let’s apply this formula to a 1.5-ton AC.
Example Calculation:
- If your 1.5-ton AC consumes 1500 watts (on average), and you are using 250W panels, you would need about 6 panels:
- 1500 ÷ 250 = 6 panels
- If you choose 400W panels, you would need about 4 panels:
- 1500 ÷ 400 = 3.75 panels ≈ 4 panels
This calculation assumes that your solar panels receive 5-6 hours of good sunlight per day, which is typical in many regions of Pakistan, especially during summer months. Here is the table answering How many solar plates are required for 1.5 ton AC in Pakistan:
Summary Table:
| Solar Panel Wattage | Number of Panels Required (for 1500W) |
|---|---|
| 250 watts | 6 |
| 300 watts | 5 |
| 400 watts | 4 |
Considerations for Using Solar Panels to Run a 1.5 Ton AC
While the basic calculation gives you a good idea of how many solar panels would be required for 1.5-ton AC, there are several other factors you must consider when setting up a solar-powered air conditioning system.
Sunlight Availability in Pakistan
Pakistan is blessed with abundant sunlight, especially in areas like Punjab, Sindh, and Balochistan. These regions receive 5-6 hours of strong sunlight on average, which is enough to generate substantial power through solar panels. However, during the winter months or rainy seasons, the sunlight may not be as consistent, which could affect the performance of your solar system.
Efficiency of Solar Panels
Solar panels lose some efficiency due to factors such as dust, shading, and temperature. It’s always a good idea to add an extra panel or two to compensate for these losses. For instance, if your calculation suggests that you need 4 panels, you might consider installing 5 panels to ensure a reliable power supply even when sunlight is less than ideal.
System Losses
When converting solar energy into usable electricity, there are some system losses due to inverters, wiring, and battery storage (if applicable). It is recommended to factor in around 10-15% losses when calculating the number of panels needed.
Using Batteries for Backup
If you plan to run your AC at night or during low sunlight periods, you will need a battery backup system. Without batteries, you can only run the AC during the day when sunlight is available.
