Can You Run an AC on Solar Power in Uttar Pradesh?
With summer temperatures crossing 45°C in cities like Lucknow, Kanpur, and Agra, air conditioning is a necessity. However, running an AC leads to massive electricity bills. The good news is: Yes, you can absolutely run your AC on solar power.
But how many panels do you actually need for a 1 Ton AC? Let's break it down.
Power Consumption of a 1 Ton AC
A typical 1 Ton inverter AC consumes about 1,000 to 1,200 watts (1-1.2 kW) of power while running. Older non-inverter models can consume up to 1,500 watts.
If you run your 1 Ton AC for 8 hours a day, it will consume roughly 6 to 8 units of electricity daily.
The Right Solar System Size
To comfortably run a 1 Ton AC along with basic home appliances (fans, lights, fridge), you need a minimum of a 3kW solar system.
Here's why:
- A 3kW system generates about 12-15 units per day in UP.
- Your AC consumes ~8 units.
- This leaves 4-7 units for the rest of your house.
On-Grid vs Off-Grid for AC
On-Grid System (Recommended):
During the day, your AC runs directly on solar power. If a cloud passes, the grid seamlessly provides the shortfall. At night, you run your AC on grid power, but you pay for it using the "credits" you earned by exporting excess solar power during the day via net metering.
Off-Grid System (With Battery):
If you want to run your AC during a power cut, you need an off-grid or hybrid system with a robust battery bank (Lithium-ion is highly recommended). You will need an inverter with at least a 3.5kVA to 5kVA rating to handle the initial starting surge of the AC compressor.
Cost to Install a 3kW System for AC
A high-quality 3kW on-grid solar system in UP typically costs between ₹1,75,000 to ₹2,20,000. However, with the PM Surya Ghar Yojana subsidy of up to ₹1,08,000, your effective out-of-pocket cost is drastically reduced.
