The exact number of solar panels required to power a 1-ton AC is determined by various factors, including the air conditioner's capacity, the size of the room, and other weather conditions.To figure out how many solar panels you'll need to power a 1-ton air conditioner, first, calculate how much electricity it consumes, then multiply that number by the number of solar panels you'll need to create that quantity of electricity.

A 1-ton air conditioner uses between 1200 to 1500 watts of power, so you'll need about 6 250-watt solar panels to meet that need. If you wish to utilize solar electricity to power any other appliances except your air conditioner, you'll need more solar panels, which will be decided by the number of items and their total electrical wattage.

Let's make a quick computation to give you a rough notion of the numbers:

Before we begin, we must first determine the capacity of the AC you are using. Because you mention it's a one-ton AC, it indicates it'll need roughly 1200 to 1500 watts of power.

Now that we know the wattage of our AC, we can figure out how many modules we'll need:

To create 1500 watts of power, you'll need the following:

• 6 panels, every 250 watts, 
• or 5 panels, every 300 watts, 
• or 4 panels, each 400 watts

A 1.5-ton air conditioner uses roughly 2500 watts of power on average, thus ten 250 watt solar panels would be required to meet this demand. Furthermore, if you intend to purchase an inverter, you will require a 2.5 kVA grid inverter.

Ten 250-watt solar panels will be enough to power a 1.5-ton AC. You'll need an additional ten modules if you currently have ten solar panels installed to power other electrical devices.

A 3-ton air conditioner uses roughly 3000 to 3500 watts of power on average. To equal that amount of electricity output, you'll need fourteen 250-watt solar panels merely to power the air conditioner.

Although it is not a great option to operate a 3-ton AC entirely on solar panels since it will not be able to generate enough power to keep the AC running for an extended period of time. So, if there isn't enough sunshine to keep the AC going, you may use your grid-connected electricity as a backup.
