Can You Run Air Conditioning On Solar Power?
It is possible to run an air conditioner with solar power. You can set up an air conditioner to get power from the grid, directly from solar panels, or a battery charged by solar panels. However, it can be a considerable investment at the beginning.
But, it would be best if you considered the long-term benefits of having such a system in place for independence and money saved on the electric bill. If you already have an air conditioning system, you can switch it to solar by adding a converter and battery unit. (sources)
How Does Solar-Powered Air Conditioning Work?
Solar-powered air conditioning works the same way as a typical air conditioning system. The only difference is in the source of energy. Instead of getting the power from the grid, it gets it from the solar panels.
There are different types of solar air conditioners to choose from:
- Solar photovoltaic air conditioners
- Solar thermal systems
- Absorption chillers
Solar Photovoltaic Air Conditioners
The most common is the solar photovoltaic air conditioner. It works with solar panels responsible for absorbing energy from sunlight. The panels are usually situated on the house roof and can power an air conditioner directly or through a solar battery.
The solar panels could be only part of your air conditioning system or provide energy for the entire house, including the air conditioner.
Suppose you have a solar system with batteries. It is possible to store the additional electricity produced and use it during the night or when the weather doesn’t allow the solar panels to produce electricity. (source)
Solar Thermal Systems
A solar thermal system can also power air conditioners. It is a way of producing electricity through a plate that can harvest solar energy. The collected energy can activate the compressor responsible for cooling the air.
Absorption chillers are another cooling system that uses solar panels to make the fan and the compressor work.
What Are The Options Available?
There are several options for powering a solar air conditioner system. They can get power in the following mode:
- Hybrid system
DC-Powered Air Conditioners
DC-powered air conditioner systems run on a direct current, which means the air conditioner gets electricity directly from the source (the solar panels). However, the source can be batteries (also charged with solar energy), and therefore it is a type of system that can be run off the grid entirely.
It is a simple system since the solar panels produce direct current (DC) and can power the air conditioner directly. It is a perfect system to live off the grid with the minimal equipment required, and it is a relatively easy system to install.
AC-Powered Air Conditioners
AC (alternative current) powered air conditioner systems require an inverter to convert electricity from DC (direct current) to alternating current from the solar panels.
Therefore, one of the most significant advantages of choosing an air conditioner system that runs on AC is that you can also connect it to the grid.
So in case there is no sun, and solar energy is not available, you can always keep the air conditioner working through the standard electric current.
In addition, if you have the solar panels connected with the grid, too, the excess electricity can go back to the grid in exchange for credits.
Hybrid Air Conditioners
Hybrid-powered solar air conditioners can run in DC and AC modes. They could also be connected to the grid and the solar panels (or batteries charged by the solar panels) simultaneously.
One could switch between one system or the other depending on what type of electricity is available. For instance, at night, one could use the electricity from the grid when the sun is not out.
Can I Save From Using A Solar-Powered Air Conditioner?
The main advantage of a solar-powered air conditioner is that it can economize significantly on the energy bill. According to estimations, it is possible to save up to 40% on electricity using solar energy to power air conditioners.
Indeed, the original investment to set up a solar-powered air conditioner system is pretty high. However, it is possible to get back the initial investment and way more by lowering the monthly electric bills.
An air conditioner should last between 15 to 20 years, and solar panels can last for 25 years. So a homeowner could already get back the original investment in the first few years of operation.
The number of panels and the efficiency of the components of the system determines how much you can save.
System Components Include
- Solar panels
- Converters (when applicable)
The more efficient the batteries and the panels, the more energy you can save.
What Are The Real Benefits Of Solar-Powered Air Conditioners?
Besides the upfront costs and the unpredictable weather, there are many advantages to a solar-powered air conditioning system, which are:
- Long term saving costs
- Ability to be independent of the grid
- Easy maintenance
- Better for the environment
Traditional air conditioners produce a lot of CO2, while solar energy is clean and renewable. Once the panels are mounted, they require minimal maintenance and cleaning. Even in the case of snow, you can let it melt, and it falls off pretty quickly.
In addition, solar air conditioning is durable. Once you set it up, it will last for decades.
Best Solar Powered Air Conditioners
With enough solar panels, a suitable inverter, and a proper battery system, you can run a good air conditioner on solar energy. If you want to run an off-grid air conditioning system, you have to consider the following things:
- You have to generate enough power
- You have to work out how many solar panels do you need
- Select a proper battery system
- Select a proper inverter
- Select the right AC system
An air conditioning system consumes quite some energy, and you have to calculate precisely how much and estimate the number of panels you need to run the system. For example, if your air conditioner requires 1.2 KW and is on for the entire day, the system requires almost 29 KW per 24 hours. With this in mind, you can estimate what solar panels you need and how many.
Selecting The Battery
The next thing to figure out is the battery bank you need which has to be large enough to store enough energy to run the system in case necessary.
It would be best to have enough solar panels to charge your batteries and run the air conditioner without problems. In addition, an inverter is necessary to run an off-grid solar-powered AC system.
The inverter should have a good efficiency so that you will not lose too much electricity on the way.
Finally, you have to choose the right system between the many already available.

Pros And Cons Of Solar Air Conditioners Systems
Using solar energy to power air conditioning and the rest of the appliances has several advantages and disadvantages.
The most apparent benefit is the lower energy costs on the positive side. The sun is always there, and it is an excellent idea to set up a system to harvest sunlight. (source)
In some cases using solar energy is the only solution for those living far away from the grid, and the only option is either solar energy or a portable generator.
Solar energy is durable and requires minimal maintenance. In addition, the warranties can last for a long time if you choose a good provider for the solar system and the AC system. Unfortunately, there are also negative points about solar energy, such as the dependency on the weather and the fact that you can’t use it at night (although you could remedy the situation with a battery system).
You could also live in a state that is not friendly toward solar energy, and it could be too expensive to have a solar system since there is no facilitation from the state or government.
Other Essential Factors To Consider
While it is easy to be an enthusiast in getting a solar system to power your air conditioning system because of the many advantages, you should consider other factors carefully.
Here are some essential points to consider:
The Size Of The House
If you have a large house, it is necessary to have a powerful air conditioning system with a big capacity. In that case, you are looking at the necessity of getting more solar panels installed, resulting in a higher initial expense to get the system working.
The climate can impact the number of solar panels you need and thus the initial costs. If you live in an area with a lot of sunlight, it is possible to get away with a lower number of panels since the solar energy collected will be much higher.
Depending on the energy consumption, you need to consider how many batteries you might need for your system. It is good to have batteries to run the system at night. But also because in the case of clouds, you have a backup.
It is better to have a battery capacity that can last for a few days in emergencies or unpredictable events. It becomes essential if you also run other appliances on solar energy and if you are disconnected from the grid.
