Why We Need Solar Powered Air Conditioners?

With solar – powered AC units, you may still need to use electricity from the main power grid, but your consumption will drop up to 50%, depending on your climate. So, with solar power AC, you can save tremendous amounts of money on AC bills. This also helps to offset the initial high installation costs of solar panels Switching towards solar powered central air conditioning or installing solar powered window or portable air conditioners can be a great step towards fighting the current climate crisis.

Benefits of Solar Air Conditioning

The solar panel air conditioners provide several advantages. The only downside is that they require a high initial investment.

1. Increases the Value of Your Property

In addition to environmental benefits, solar panel air conditioners can also help increase the value of your home. The buyers are willing to pay more for homes with solar air conditioning.

2. Saves on Bills

With solar – powered AC units, you may still need to use electricity from the main power grid, but your consumption will drop up to 50%, depending on your climate. So, with solar power AC, you can save tremendous amounts of money on AC bills. This also helps to offset the initial high installation costs of solar panels.

3. Reduces the Energy Demand

Conventional AC systems operating during the hottest days can overload the electricity grid, leading to power outages in summer. Solar air conditioners are particularly helpful as they lower the demand during peak usage by shifting the load from the main grid. This can help reduce the frequency of power blackouts and brownouts.

4. No Greenhouse Gas Emissions

As solar energy is a renewable source, the solar power air conditioning units reduce the dependence on fossil fuels. This, in turn, helps to lower the emission of greenhouse gasses that contribute to global warming.

Even with solar – powered air conditioners, there are a few different options available. These differ based on the mode of power that the air conditioner is getting. Let’s see them below.

• DC Powered Solar Air Conditioners

Also known as conventional solar – powered air conditioners, DC solar air conditioners run on direct current (DC) electricity, meaning that the solar panels are directly wired to it. They can run through the batteries, which are charged through solar power; therefore can run entirely off – grid. They use solar panels, photovoltaic panels to collect sunlight and turn it into electric energy. This type of air conditioner provides a few major advantages, which are:

• As a solar panel produces DC electricity, running such an air conditioner directly off the solar panel will not be a problem.
• DC – powered solar air conditioners are the go-to option for complete off-the-grid living and you can run them with minimal extra equipment cost, as in AC – powered air conditioners.
• They are easy to install and maintain.

The disadvantage of such a system is that you would need a hefty battery bank to supply power for night time operation. The other option is to use a rectifier device to convert the AC electricity from the power mains to DC and then run the air conditioner. Still, it defeats the whole purpose of a solar – powered air conditioner!

• AC Powered Solar Air Conditioners

Alternating Current is the more well – known solar air conditioner. For AC air conditioners to run with solar power, you need a device known as an inverter, converting the DC from the solar panels into AC. The inverter is an integral part of such a setup. Moreover, the solar powered air conditioner then uses up the energy stored in a battery after passing through the inverter. Due to this reason, AC powered solar air conditioners provide the following advantages:

• These air conditioners can also be tied up to the grid power and run as a standard air conditioner. You don’t require an extra equipment since this air conditioner can run on AC power.
• The primary advantage of such a system is that you can run it with grid power and solar panels.
• If these ACs are tied to the grid, you can give excess electricity produced back to the grid and get credits for it by a process called net metering.
• Hybrid Powered Solar Air Conditioners

Hybrid solar-powered air conditioners can run on both DC and AC at the same time, seamlessly. Such units can be connected to both the solar panels/batteries directly and to the grid at the same time. The unit can then use the appropriate power source according to the time of day and power load.

• There is no additional equipment, such as an inverter, which means the total costs are also less.
• They can switch between solar power and grid power smoothly.
• They are very flexible to operate during all times of the day and seasons.

The disadvantage of this system is that if your batteries are not charged and installed it off-grid, it won’t work at night.

How Does a Solar AC Work?

A solar air conditioner combines solar electricity and air conditioning. In simple words, it takes energy from the Sun and uses it to power your AC to cool your space!

A solar panel is a device that captures the power of the Sun. It converts the Sun rays into electrical energy. This energy can then be used directly or stored in a battery. This is known as DC power. A solar – powered air conditioner then uses this DC power, either directly as DC or after conversion into AC (using an inverter), and heats or cools your home. Instead of using grid energy, a solar – powered air conditioner uses the energy of the Sun. It can use the grid energy, though, if needed.

The solar AC units collects energy in two ways: photovoltaic (PV) systems or solar thermal systems. Solar PV systems use photovoltaic panels to generate electricity, while solar thermal systems work like solar water heaters. They use up the sun’s energy to heat up water which then changes the refrigerant into a heat-absorbing gas that provides air-conditioned air to your home.

Factors to Consider When Shifting to Solar Powered AC

Here are some factors to consider when choosing a solar power air conditioner for your home.

• Climate Conditions

Areas that receive more sunlight around the year and have longed summer season will only require a few solar panels. On the other hand, if you are in a location that gets less light will need more panels and a bigger battery for backup to harness the sun’s energy.

• Size of Your Home

If your home is larger, it will need more AC capacity for air conditioning the entire space. So, you will need more solar panels as compared to a smaller area. On average, most homes need 10 to 20 solar panels to cover all the electric appliances.

• Battery

If you live in a mild climate that doesn’t get much sunlight, it’s best to invest in batteries. Opting for batteries is also a good idea if you want to go completely off – grid so you can store solar energy for the night and on cloudy days.

What Is the Make Your Solar Powered Air Conditioners Smart

Saving energy with solar powered air conditioning is one step; save even further with smart air conditioning! Pair your mini – split, window, or portable air conditioner with a smart AC controller for home climate automation and greater savings. Smart AC controllers can help you save up to 25% on electricity bills. Moreover, you can also control your solar – powered AC unit from anywhere using your phone, set weekly schedules, enable geofencing or set other intelligent triggers for your home cooling and heating!

Is Switching to Solar Air Conditioning Worth It?

Solar-powered AC’s can be a game – changer. With modern, efficient air conditioners, powering through solar energy is becoming more simple year after year. Considering environmental benefits, energy savings, and tax credit, solar powered air conditioners are an exceptional choice for heating and cooling requirements.

Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth’s surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity. A geothermal energy cooling / heating system is based on using the full potential of the constant temperature and thermal conductivity of the earths substructure.

We can see this phenomenon in basement areas where during the summer the area is cool and during the winter warm without the use of air conditioning.

Geothermal energy can be broken down into two categories: open loop systems and closed loop systems.

Open loop geothermal energy for cooling / heating is the pumping of under ground water source through a heat pump (or VRV) and the return of the water after the energy transfer. This method needs a constant water supply.

Closed loop Geothermal energy systems can be divide into two categories.

Horizontal closed loop Geothermal energy system is installed at least 1.5 meters below the ground with pipe spacing of at least 1.8 – 2.2  Rm per m². Output is 20 – 35W/m². This system has the disadvantage of requiring a large area to be installed.

Vertical closed loop Geothermal energy system where the loop is installed in a vertical bore well (6” – 8” diameter) and 60 – 120 deep. The minimum distance between the wells is 5 meters and the output is 40-70W/meter of depth, and depending on the soil structure. This system is more popular as you need less space and have a higher output.

The heat which is collected from the earth is transferred to the  system (heat pump, chiller, VRV, etc.) and the exchange is made via heat exchangers and transferred to the cooling circuit of the unit as in a normal system. Due to the fact that the temperature is constant in the earth (±18.5°C) the energy required for this  this process is much less than in a normal system where the  air temperature is 40°C in summer and 5-10°C in winter.

Geothermal  energy can be used for under floor heating, fan coils, or for VRV systems, and the savings in comparison to a normal Air to water system can be up to 50-60% depending on the application and use of system.
