AC on Solar Power – Worried about running your air conditioner because of high electricity bills? What if we told you that you can now run your AC “full blast” using solar panels and practically pay nothing on your monthly bill? In 2025, solar-powered AC setups are becoming not just popular, but affordable and practical for Indian households.
Let’s break down how to run your AC on solar, how much it costs, and how much you’ll save.
How Much Power Does an AC Use?
A 1.5 Ton Inverter AC typically consumes:
- Around 1.2 to 1.5 kWh (units) per hour
- 6 hours/day usage = 7–9 units/day
- Monthly consumption = 200–250 units
To offset this with solar, you need a system that can generate 8–10 units per day.
Ideal Solar System to Run an AC
| AC Usage Type | Recommended Solar System |
|---|---|
| 1 Ton AC (6 hrs/day) | 2kW – 2.5kW system |
| 1.5 Ton AC (6 hrs/day) | 3kW – 3.5kW system |
| 2 Ton AC (8 hrs/day) | 5kW system |
Each 1kW of solar panel generates about 4 units/day in good sunlight. So for AC, a 3kW system is usually the sweet spot.
Total Cost of Solar Setup in 2025 (India)
| System Size | Price (₹) | After Subsidy (₹) | Bill Savings/Month |
|---|---|---|---|
| 2kW | ₹1.2 – ₹1.5 lakh | ₹55,000 – ₹70,000 | ₹1,500 – ₹2,000 |
| 3kW | ₹1.6 – ₹2.0 lakh | ₹75,000 – ₹90,000 | ₹2,500 – ₹3,000 |
| 5kW | ₹2.4 – ₹2.8 lakh | ₹1.1 – ₹1.3 lakh | ₹4,000+ |
Subsidy available under PM Surya Ghar Yojana for residential rooftop systems.
