With temperatures rising every year and electricity bills burning a hole in people’s pockets, many homeowners are shifting towards solar energy. A common question among new users is – Can a 2kW solar panel run a 1.5-ton AC? The answer isn’t simple, but don’t worry. In this article, we’ll break it down in an easy-to-understand way using simple language.
Power Consumption of a 1.5-Ton AC
A 1.5-ton air conditioner is a standard choice for medium-sized rooms in Indian homes. On average, it consumes around 1.5 to 2 kilowatt-hours per hour, depending on the model and its energy efficiency rating. Newer inverter ACs are more energy efficient, while older ones might consume even more power. If you use this AC for 8 hours a day, it can easily consume between 12 to 16 units of electricity daily. In a month, this adds up to nearly 360 to 480 units, which is quite a heavy load for any small solar setup.
How Much Electricity Does a 2kW Solar Panel Generate?
A 2kW solar system usually consists of 4 to 5 solar panels, depending on the brand and wattage per panel. Under ideal conditions, such a system generates around 8 to 10 units of electricity per day. This is assuming that the panels receive about 5 hours of full sunlight daily, which can vary depending on your location and the season. So, on average, a 2kW solar panel setup produces around 240 to 300 units per month – much lower than the monthly electricity needed for running a 1.5-ton AC daily.
Can a 2kW System Run a 1.5-Ton AC?
If you’re planning to run the air conditioner only for 2 to 3 hours a day, and if you have an energy-efficient inverter AC, then a 2kW solar system might handle it, but just barely. However, if you plan to use the AC for 6 to 8 hours or more every day, then 2 kW of solar power is not enough. You’ll either have to use power from the grid or have a battery backup system to make it work. Most experts recommend installing at least a 3kW to 4kW solar system for running a 1.5-ton AC comfortably, especially during summer when usage increases.
While a 2kW solar panel system is excellent for powering lights, fans, TVs, and small appliances, it is not suitable for high-power devices like air conditioners for long hours. It might work in limited situations, but for full comfort and long-term savings, upgrading to a higher-capacity solar setup is the smarter choice. Always calculate your energy needs and consult a professional before making an investment in solar power.
