Before go and purchase your solar panels to run your air conditioners, you need to calculate the electricity needed to run your AC. Based on the result, you can have the final number of solar panels to power it.

Let’s walk through the steps you need.

First, electricity needed.

The Electricity Needs to Run a House Air Conditioner on Average

In general, we use central and window air conditioners for our house. The energy consumption depends on the usage and other factors.

A central air conditioner requires 3000 to 3500 watts of power per hour operating. It will depend on the running mode of the air conditioner.

A small window air conditioner uses 500 Wh while a medium air conditioner uses 900 Wh per hour. On the contrary, a large unit will consume 1440 Wh.

However, the number of portable air conditioners is not fewer than central or window. A medium-size portable air conditioner needs 2900 watts of energy per hour.

The electricity needed to run a house air conditioner depends on the brand, technology, mode, and other things.

How Much Power Does a Solar Panel Produce a Day?

It’s not easy to determine the actual power output of a solar panel when considering the energy production rate/wattage. You will get solar panels with different sizes and energy production capability.

A 500 watts solar panel can produce 3000 watts of energy under 6 hours of bright sunlight.

The energy production rate depends on solar panel size, the efficiency of the cell, sunlight, and your location.

Solar panel manufacturers produce solar panels of different sizes, it affects the output because of space. A large solar panel can produce more energy, it is not always true. A small solar panel with standard cells and materials can also generate more energy.

The efficiency of a solar panel is related to solar cells. Solar cells are the small blocks that you see on the top of the panel in blue color. This silicon cell comes with diverse quality and efficiency. A solar panel with high-quality solar cells can generate sufficient power for years.

Most importantly, sunlight is the fuel of the solar panel. Without sunlight, you can not get power even from the most efficient panel. A solar panel converts sunlight to photovoltaic energy for producing electricity.

So, it is important to locate your solar panel in a sunny place. You have to ensure that sunlight is available in this place at least for 6 hours a day. Otherwise, you won’t get the expected power from the solar system.

The south-facing solar panel gets sunlight for the whole day. It is prohibited to install solar panels under trees and shades of houses.

However, you can’t ignore the location while installing a solar panel. We know that the solar system is perfect for remote areas where electricity is unavailable. But, a foggy area will interrupt energy production.

Though there are solar panels that can produce power in foggy weather, it is not trusted and efficient enough for producing expected power. Direct sunlight is the best solution and you have to install the panels in a sunny location.

Here is the chart with several solar panel sizes and the power that they can generate when getting direct sunlight for 6 hours.

How Many Solar Panels Does It Take to Run an Air Conditioner?

As we discussed, a small window air conditioner uses an average of 500 Wh every hour operating. If you want to run this air conditioner on solar power, you have to install a single 500 watts solar panel.

The panel can generate 500 watts per hour under bright sunlight and this energy is enough for running a small window air conditioner.

There are different types of solar panels with various power outputs. You can also install two 200 watts solar panels and a single 100 watts panel. But, purchasing more solar panels will cost you more. It is better to install a large solar panel that fits the air conditioner.

On the contrary, a 200 watts solar panel is capable of running a 200 watts air conditioner. The size is too small and you can only run a portable small air conditioner with a single 200-watt solar panel.

To operate a single one-ton center air conditioner (3500 watts), you need around 7×500 watts solar panels in total to have your air conditioner working fine.

If you have a complete solar energy system, you can use multiple 200 watts solar panels on the rooftop. You have to consider the size of the solar panel and space where you want to install them.

Large solar panels will save your space and installation cost. Similarly, they are easy to maintain and repair.

The air conditioner is a heavy home appliance with a high energy consumption system. So, before calculating the power and measuring the space, you have to install the most suitable options that stand out.

Again, it is up to you how many solar panels you will install for your air conditioner. Try to come up with an expert’s opinion and don’t just purchase unnecessary solar panels to fill up your rooftop.

Let’s explore the chart to learn more about the number of solar panels.

Yes, you can run several air conditioners on solar power. 

If an office, industry, or city can run with solar power, why don’t you? Now, you can run everything with solar energy. Here are a few steps that illustrate how you can do this.

First, you have to calculate the power and energy consumption rate of the air conditioners that you want to run from a single power source. Start communicating with solar energy professionals who will lead you to find out the number of solar panels for the project.

It will help you to save installation costs and guide you to walk on the right track for establishing an independent power source for your air conditioners.

Second, finalize the air conditioner type and the pace for solar panels. Central, window, and portable air conditioners require different installation processes but the same power source.

The next steps are installing solar panels, converters, and additional power storage if you want a backup. But, it is expensive to make additional storage for many air conditioners.

Now we present some advantages and disadvantages of running many air conditioners on a single solar power source.


You will save installation costs and a single space is enough for multiple air conditioners. That means if you have many air conditioners, you don’t need to install several panels separately.

This system will give you a cost-effective solution from massive electricity bills. You have to invest one time and you will receive the profit for at least 25 years.

You can run the air conditioners from an independent power source.


You have to invest more in heavy energy production. If you have more than 3 air conditioners, the system will need at least 9000 watts of energy capacity. 

Establishing a 9000 watts solar system, requires multiple panels, converters, and huge space. The installation cost will be increased.

If you don’t have energy backup and additional power storage, then it is difficult to get power due to the lack of sunlight.
