A Complete Guide To Solar-powered Air Conditioners

A solar air conditioner is any indoor air conditioning device powered by solar energy. The sun is most active in the hot seasons, and air conditioning is indispensable. But its constant use is negatively reflected in electricity bills.

If a solar system is installed in the household, it is advisable to connect a solar-powered air conditioner to it. What are the advantages of solar air conditioning, can a solar panel power an air conditioner, on what principle does solar power air conditioning work, and whether the costs are commensurate with the savings will tell the material.

Why Are Solar Powered Air Conditioners Necessary?

Air conditioning systems in the country use about 10% of household electricity consumption per year, which translates into a phenomenal amount of $11 billion. But cooling houses has a second negative side – harmful emissions into the environment, approximately 130 million tons of carbon dioxide per year.

Therefore, switching to solar-powered air conditioning can significantly reduce the financial cost of electricity and the carbon footprint on the environment. The number of consumers switching to energy-saving technologies for the electricity production is increasing every year, indicating citizens’ social responsibility.

Whichever solar power air conditioning system you choose, a central cooling system, window, or mini-air conditioner will be the right solution for personal comfort and energy independence.

Solar Air Conditioning Advantages

As with installing solar panels, the main problem is that air conditioner solar power requires a significant initial investment. But this disadvantage is offset by the advantageous features.

  • Reducing power consumption: Turning on conventional AC split systems consumes a lot of power, and the network is overloaded when the air conditioners operate on hot days, and power outages occur. Using a solar-powered air conditioning unit removes the load from the central grid, reducing the frequency of outages.
  • Environmental aspect: Carbon dioxide emissions exacerbate the greenhouse effect and negatively affect external harm and human health. Solar energy air conditioners do not affect the environment and do not emit greenhouse gases.
  • Savings on utility bills: Installing a solar energy air conditioner will help reduce the power supply from the central power grid by 50% or more, depending on the climatic features of the place of residence. Such savings will allow you to quickly offset the cost of installing a solar HVAC system.
  • Increasing the value of the real estate: Equipping a house with solar-power air conditioning systems isometimes increases real estate costs. Buyers willingly agree to pay more, acquiring partial or complete energy independence.

A house with a solar-run air conditioner will maintain a comfortable atmosphere in any weather outside.

Options for Solar-powered Air Conditioning

Solar-powered air conditioners for homes can be of several types, depending on the way the split system is powered:

  • AC solar air conditioner
  • Direct current
  • Hybrid installations
  • Absorption heat conditioners

Each type has advantages and disadvantages that must be considered when choosing air conditioning equipment.

DC Installations

This type of air conditioner works by direct connection to solar panels. The device can also be powered by a battery charged with solar energy, which ensures the autonomous operation of the split system. Photovoltaic solar panels are in use to run the air conditioner. The advantages of the device are the following:

  • Easy start of the air conditioner
  • Minimal equipment costs
  • Ease of installation and maintenance

The disadvantage of solar DC air conditioners is purchasing a large-capacity battery to power the house at night.

AC Cooling Equipment

Solar power AC systems are more common in air conditioners. For the cooling equipment to work, an inverter is required to convert the direct current from the panels into an alternating current. The benefits of using solar AC are the following:

  • The ability of the air conditioner to operate both from solar energy and from a network with alternating electric current;
  • Excess energy, if the air conditioner is connected to the central power grid, can be returned to the network and receive loans under a special program – net meter.

The cooling device can use the energy that passes through the inverter and is stored in the batteries.

Hybrid Equipment

The peculiarity of this type of chiller is that AC and DC can be used for solar power. The advantages of installations are the following:

  • Smooth switching between grid and energy from solar panels
  • Opportunities to work in all seasons and hours of the day
  • Lower costs due to no need for additional equipment

The downside is that the split system needs to be connected to the network or charged batteries at night.

Thermal Systems

The fan drive and chiller heat pump are powered by energy from solar panels for air conditioning. They are in use in devices that produce cold air through evaporation, and a battery charged by a solar station can power them.

How Does a Solar AC Operate?

The operation of the air conditioner with solar panels is to convert solar radiation into energy, which is used to power split systems. Solar-powered AC unit collects solar radiation by using the following:

  • Photovoltaic systems – familiar panels
  • Thermal – solar energy is in use to heat water. It converts the refrigerant into a gas that absorbs heat, cooling the room’s air.

Some systems operate only on solar energy to ensure autonomous solar air cooling. Their efficiency is great, but a more practical option is hybrid installations.

Considerations for Switching To Solar-Powered AC

Solar to run air conditioners is a promising direction. When switching to solar air conditioners, there are several factors to consider:

  • Climate: Different areas receive sunlight in different amounts, so the volume of the solar station will be different, which will affect the cost of installations.
  • Parameters of the house: The larger the size of the house, the more solar panel to power air conditioners would be necessary to buy.
  • The need for a battery: For people living in areas with little sunlight, it is important to choose the right batteries that will store energy and deliver on cloudy days and at night.
  • Return on investment: Whichever solar-powered AC system the user chooses, the equipment will pay off quickly.

Solar panel AC units have different power and size. It is important to calculate the required power needed to provide the house and choose a device that meets the energy needs.

How Much Do Solar-powered Air Conditioners Cost?

The cost of solar-powered AC air conditioners is variable. The total price for homeownership will depend on the following:

  • Battery
