If you want to run a 1.5-ton AC on solar power and are confused about how many solar panels you’ll need, the cost, and the factors that affect it, we will cover all this information in this article.
How Many Solar Panels Needed for a 1.5 Ton AC?
To power a 1.5-ton AC, you need 4 to 5 solar panels of 585W each.
This calculation assumes the AC consumes about 1.5 kW per hour and operates for 8 hours daily, requiring 12 kWh/day.
The exact number depends on factors like AC efficiency, sunlight availability, and panel output.
Higher-efficiency panels or areas with more sunlight can reduce the total panels needed.
Additionally, including a battery backup system ensures uninterrupted operation during cloudy days or nighttime.
Understanding the Power Requirements of a 1.5 Ton AC
| Aspect | Details |
|---|---|
| What Does “1.5 Ton” Mean? | – The term “1.5 ton” refers to the cooling capacity of the AC. – One ton equals 12,000 British Thermal Units (BTUs) per hour. – A 1.5-ton AC has a cooling capacity of 18,000 BTUs per hour. |
| Power Consumption | – The average power consumption of a 1.5-ton AC ranges from 1.5 kW to 2 kW. – Regular ACs: Consume closer to 2 kW. – Energy-efficient ACs (5-star rated): Consume around 1.5 kW. |
Calculating the Number of Solar Panels Required
To determine the exact number of solar panels, follow these steps:
| Step | Description | Formula |
|---|---|---|
| Calculate Total Daily Energy Consumption | Determine the total energy required daily based on appliance power and usage hours. | 1.5 kW × 8 hours = 12 kWh/day |
| Determine Energy Production per Solar Panel | Estimate the energy production of a single solar panel based on its capacity and sunlight hours. | A 585W solar panel produces about 2.925 kWh/day in areas with 5 peak sunlight hours. Calculation: 585W ÷ 1000 × 5 hours = 2.925 kWh/day |
| Divide Total Energy Consumption by Energy Produced per Panel | Calculate the number of solar panels required by dividing total energy consumption by energy per panel. | 12 kWh ÷ 2.925 kWh ≈ 4.1 panels (round 4 – 5 panels) |
Solar Panel Requirements for Different Star Ratings of ACs
| Star Rating & Type | Maximum Wattage (W) | Total System Size Needed (kW/day) | Number of 585W Panels Required |
|---|---|---|---|
| 1-Star Non-Inverter AC | 2,200 W | 17.6 kWh/day | 6.0 panels ≈ 6 panels |
| 2-Star Non-Inverter AC | 2,000 W | 16.0 kWh/day | 5.5 panels ≈ 6 panels |
| 3-Star Inverter AC | 1,800 W | 14.4 kWh/day | 4.9 panels ≈ 5 panels |
| 4-Star Inverter AC | 1,600 W | 12.8 kWh/day | 4.4 panels ≈ 5 panels |
| 5-Star Inverter AC | 1,200 W | 9.6 kWh/day | 3.3 panels ≈ 4 panels |
💡 Pro Tips for Running a 1.5 Ton AC on Solar Power:
- Use a 5-star rated inverter AC for maximum energy efficiency and lower power consumption.
- Ensure your location receives at least 5 peak sunlight hours for optimal energy production.
- Include a battery backup system for uninterrupted cooling during nighttime or cloudy days.
- Perform regular Cleaning of your solar panels to ensure maximum efficiency.
- Consult a professional to customize the solar setup based on your specific energy requirements.

Key Factors to Optimize Your Solar Setup
When planning a solar setup for your AC, consider the following:
- Inverter Capacity: Ensure the inverter can handle the load of the AC and other appliances.
- Battery Backup: If you need power during the night or cloudy days, include a battery system. Account for energy storage losses.
- System Losses: Factor in losses due to wiring, inverters, and inefficiencies (usually 15-20%).
Final Thoughts on Solar Panel Requirements for a 1.5 Ton AC
To power a 1.5-ton AC effectively, you’ll need around 4 to 5 solar panels (585W each), depending on your location, AC efficiency, and daily usage. Investing in energy-efficient appliances and high-quality solar panels can reduce costs and maximize system performance. Proper planning ensures that your solar setup meets your cooling needs while being environmentally friendly.
