Solar Panel for AC: How Many Air Conditioners Can a 5 kW System Run? (2026)
A 5 kW solar panel system can run 2–3 × 1.5 ton inverter ACs simultaneously during peak sunlight hours, making solar power a practical and cost-effective solution for Indian homes with high AC usage.
TL;DR
A 5 kW solar system can run 2–3 × 1.5 ton inverter ACs during daylight hours. Each 1.5 ton inverter AC draws approximately 1.2–1.5 kW per hour at full load. With 1.5–2 kW headroom for other home appliances, a 5 kW system is the right size for a well-airconditioned Indian home. For a single AC plus basic home load, a 3 kW system is sufficient.
How Much Power Does an AC Consume Per Hour?
Understanding AC power consumption is the starting point for sizing a solar system correctly. Reference figures for common Indian AC types:
Inverter ACs modulate their compressor speed — once the room has cooled, consumption drops significantly below peak draw. Non-inverter ACs run at fixed speed and consume more on average, requiring a larger solar system for equivalent cooling hours.

How Many ACs Can a 5 kW Solar System Run?
With a 5 kW solar system generating approximately 18-22 units per day in Indian conditions (5–5.5 peak sun hours in Bangalore, 5.5–6 in Hyderabad), here is how AC loads map to generation:
2 × 1.5 ton inverter ACs (2.4–3.0 kW peak) + basic home load (1.5–2.0 kW)
Total 3.9–5.0 kW — well within 5 kW system capacity during peak generation hours.
3 × 1.5 ton inverter ACs (3.6–4.5 kW peak) + minimal home load
Borderline for a 5 kW system; a 6–7 kW system is recommended for 3 ACs with full home load.
Key note: Solar generation is highest between 10am and 4pm. During these hours, a 5 kW system can comfortably power 2 ACs running simultaneously. In early morning or late afternoon hours, generation drops, and your home draws supplementary power from the grid.
“I'm very happy about the way they have set up and installed my On-Grid Solar System. The overall experience has been very good.”

What Solar Panel Size Do You Need for Your AC Load?
Recommended solar system sizes for common AC configurations:
3 kW solar system
1 × 1.5 ton inverter AC + basic home load (fans, lights, fridge).
5 kW solar system
2 × 1.5 ton inverter ACs + basic home load.
7–8 kW solar system
2 × 1.5 ton + 1 × 2 ton inverter ACs + full home load.
