Most Eco-Friendly Solar Mini Split Unit for Your Home

Most of us turn to air conditioning units for cool comfort when the weather gets hot. But have you realized that this comfort can come at a cost to the environment?

Traditional HVAC systems consume large amounts of electricity and emit carbon dioxide to the environment for every kilowatt-hour.

Replacing such devices with a solar mini split unit can help you cut your power bills and conserve the environment.

Why Solar Mini Split Units are Advantageous Over Standard HVAC Systems

Mini-splits, also called ductless air conditioners, offer countless benefits. For starters, they circulate air throughout your home without requiring any ductwork – hence the term “ductless” in their name.  

1. Solar mini-splits are cost-effective

A solar mini split air conditioner will cost you about half as much as a central air unit on average.

If your home has no existing ductwork, installing central heating, ventilation, and air conditioning system brings with it the cost of ductwork and labor.

The project also requires wall remodeling, fixture replacement, wallpapering, painting, and refinishing following a central HVAC installation.

In comparison, a ductless air conditioner will only require a small hole bored into an exterior wall.

A mini-split offers the advantage of zonal cooling and heating. You only switch on an inside unit in an occupied room. This can significantly reduce operating costs by cutting wastage.

For a solar-powered appliance, you can operate completely off-grid – getting all your air conditioning energy from the sun. This kind of arrangement means that air conditioning won’t inflate your energy bills.

2. Mini-splits are energy efficient.

At this time that we are increasingly getting conscious of how our activities impact the environment, energy efficiency is something to apprize. And solar mini splits come in handy in that regard.

Because a ductless system does not experience energy losses to the environment, its ecological impact is negligible.

Standard HVAC systems can lose about 30 percent of their energy through leaky ducts. Not to mention that they emit lots of carbon dioxide into the environment.

A ductless system does not leave any carbon footprint and uses a 100 percent eco-friendly and non-ozone-depleting type of refrigerant.  

3. Ductless systems are minimally invasive.

A mini-split AC requires only a tiny hole drilled into the wall for its installation. This is as opposed to a standard HVAC system that will require ductwork at the expense of your home’s architectural value.

Disadvantages of Solar Mini Splits

Running on solar energy means that you are out of luck when the sun is down. Of course, battery storage comes in as an ideal workaround.

Still, battery storage is often inadequate for all-night cooling despite many improvements.

Frequently Asked Questions

1. How is a hybrid solar air conditioner different from a standard heat pump?

A hybrid solar air conditioner unit can operate in two modes. It can run off an inverter when there is no sunshine as a hybrid DC unit and operate as a direct DC system when the sun is shining.

In cases where the solar panels are dedicated to cooling only, their array does not need to be connected to the local utility’s grid power.  

2. How many solar panels do I need to run a mini-split air conditioner?

For a studio apartment, small home, or recreational vehicle, about three to five 320-watt panels should get you by.

You’ll just need to go for a unit with as high a SEER rating as possible. For example, a ductless AC with a SEER rating between 18 and 27.5 can operate with less than 1,000 watts and cool 750 square feet of space. 

The SEER rating is the measure of how your pump performs with regard to energy consumption. The idea behind a high SEER rating is to find an extremely good performance.

In the HVAC world, this performance is measured as Seasonal Energy Efficiency Ratio (SEER). The ratio measures the cooling output of a unit divided by its energy consumption in watt-hours over a particular season. So what is the ideal seer rating?

An appliance with a 24 SEER produces about 24 BTUs for every watt of power. It will only need a corresponding inverter, such as a 750-watt inverter, to run it.
