In the summer heat, it’s essential to have a trustworthy cooling setup for your home. However, traditional air cooling systems often entail hefty electricity bills. That’s why we’re exploring options such as solar-powered technology to keep things cool while cutting down on energy expenses.

In this article, we’ll take an in-depth look at how solar air cooler and solar air conditioner work, as well as their advantages and disadvantages. Join us as we dissect the features, advantages, and limitations of each, empowering you to make an informed decision and reclaim control over your comfort in the face of scorching temperatures.

What is solar evaporative air cooler ?

The year 2023 is set to break records as the hottest year ever on Earth. When the heat becomes unbearable, air conditioners can provide some relief. However, if too many people rely heavily on them, the electric grid won’t be able to cope, leading power companies to cut off electricity to millions of households temporarily. Solar air coolers present a straightforward answer to this problem.

– How Does an air Cooler Work?

An air cooler consists of three primary components: a water tank, an absorbent sheet, and a fan. You fill the tank with cold water, allowing the absorbent sheet to soak it up. As the water evaporates from the sheet, it cools the surrounding air. The fan then blows out this freshly cooled air into your room, providing a natural and refreshing breeze!

Our air coolers also come with a special feature: each one includes two free ice packs. You can freeze these packs and place them in the water tank to further chill the water, enhancing the cooling effect.

Types of Solar-Powered Air Coolers

PV-powered air coolers come in three types: DC, AC, and hybrids that can use both types of power.

  • DC units: Solar panels generate DC power. If the air cooler’s fan has DC motors, it can use this power directly. These units typically operate at 12, 24, or 48 volts.
  • AC units: These units use the 120-volt AC signal from the power grid. While they can run directly from a solar panel, the panel’s signal must pass through an inverter first, which reduces efficiency.
  • Hybrid units: These units utilize both DC and AC signals. They can draw power directly from the panels when the sun is shining and from the power grid when it’s not.

Portable units are common, and window-mount units are also available. They often come with a panel array that mounts on the roof or side of the house.

What is a solar air conditioner?

Solar air conditioners are designed to cool a room using solar power. They use solar panels to make electricity for the air conditioner, and solar energy powers the condenser and refrigerant. These solar air conditioners are a budget-friendly way to cool your space. They use less electricity, which means they help cut down on carbon dioxide emissions, save on energy bills, and do less harm to the environment.

How does a solar air conditioner work?

The usual setup for a solar air conditioner is to have photovoltaic (PV) panels powering the compressor and fan. The compressor can hook up to indoor evaporative units (kind of like mini-splits) or push cool air through ducts. It gets all its juice from the panels, but there are also hybrid units that can tap into grid power. If you’re in a spot without grid power, you can add a battery to keep the air conditioner running at night.

Types of Solar Air Conditioners

Two main types of solar air conditioners are:

  • Grid-Tied Solar Air Conditioner: These are linked to the regular electrical grid. They use solar power when the sun’s up, but switch to grid power when it’s dark or cloudy. This way, you get to enjoy solar energy while keeping your space cool all the time.
  • Stand-Alone Solar Air Conditioner: These don’t rely on the regular electrical grid. They run entirely on solar power, which makes them perfect for places without grid access or prone to blackouts. They usually come with storage units like batteries to store extra solar energy for use when it’s not sunny.

Solar Air Cooler VS Solar Air Conditioner

To really grasp the gap between a solar air cooler and a solar air conditioner, we need to look at a few key factors. Check out the table below where we’ve laid out the differences between them. Let’s dive in and see what sets them apart.

Point of Difference

‎Solar Air Cooler

Solar Air Conditioner

Cost Economical




Portability ‎Yes




Function ‎Air cooler draws in fresh air from outside and cools it by passing it through cooling pads.


Air conditioners use a chemical coolant to bring down the room temperature.


Comfort ‎Not as quick and great as the air conditioner


They offer comfort by quickly cooling down the room.


Effect on Environment ‎They don’t produce Chlorofluorocarbons (CFCs), which can damage the environment.


They release Chlorofluorocarbons (CFCs), which can harm the environment.


Health Effect Helps keep the room’s moisture levels balanced, which is beneficial for patients with asthma and allergies.


They often don’t keep moisture levels balanced, which can be harmful to the skin and eyes.


Immunity They don’t work well in humid conditions.


They do fine in humid weather.


Maintenance Adding water daily is necessary, but the maintenance costs are low.


No need for daily upkeep, but air conditioners can be pricey to maintain.


Air Circulation It’s suitable for both indoors and outdoors, bringing in fresh air from outside, cooling it, and spreading it around the area. Only suitable for indoor use, so the air keeps moving around inside the room.

Which One Is Right for You?


  • Budget: Air coolers are generally cheaper upfront and to run compared to air conditioners, making them more budget-friendly.
  • Climate: Air coolers are ideal for dry climates, while air conditioners are more suitable for humid climates.
  • Room size: Air coolers are designed for smaller rooms, whereas air conditioners are better for larger spaces.
  • Health concerns: Individuals with respiratory problems might prefer air conditioners, as they can reduce moisture in the air and minimize the spread of bacteria and allergens.
