“AC solar la run pannalama?”
This is the most common question Chennai homeowners ask before installing rooftop solar.
The answer is YES – and it is actually one of the best uses of solar power.
In this guide, we explain how AC works on solar, how much solar you need, and what system is right for your home.
1. How Does AC Work on Solar?
Your rooftop solar plant generates electricity during daytime.
Your AC consumes this power directly from solar instead of EB supply.
Excess power goes to EB grid through net-metering.
At night, EB grid supplies power normally.
2. How Much Solar Do You Need for AC?
| No. of AC | Recommended Solar |
|---|---|
| 1 AC | 2–3 kW |
| 2 AC | 3–4 kW |
| 3 AC | 4–5 kW |
| 4+ AC | 5+ kW |
3. Can You Run AC Without EB Power?
Solar is grid-connected – EB acts as backup.
So your AC will run even when solar is not generating.
4. Will AC Increase My EB Bill?
No – your solar system is sized to handle your AC load.
Your EB bill will almost be zero.
5. Best AC Type for Solar Homes
• Inverter ACs consume less power
• 3-star or 5-star recommended
• Smart usage between 10 AM – 4 PM gives maximum savings
6. Chennai Sun Advantage
Chennai sunlight is strong for most of the year.
Each kW generates 4–5 units per day, making AC-on-solar highly effective.
