How Many Solar Panels Do You Need to Run a 1.5 Ton Inverter AC?

By SheikhX Engineering

The Power Math

A modern 1.5 Ton split Inverter AC runs at around 1.5kW to 1.8kW when cooling down a room, and drops to around 800W once the temperature stabilizes.

The Output Reality

If you buy a 550W solar panel, it rarely produces 550W in the peak summer heat due to thermal degradation. Expect around 450W of actual yield per panel at noon.

The Final Verdict

To safely run one 1.5 Ton Inverter AC continuously without draining your batteries, you need a minimum of 4 to 5 Tier-1 solar panels (2.2kW+ total array) specifically dedicated to that AC's load. However, to account for starting surge and other household loads, an engineer must accurately map your entire house before finalizing the panel count.
