    How Many Solar Panels to Run Air Conditioner

    Knowing how many solar panels to run an air conditioner isn’t a simple answer. There are many factors that you need to take into consideration.

    From the size of the air conditioner to the solar panel’s power output, there are factors on both sides of the party.

    We’re here to break down these factors, do some calculations, and end up with an answer depending on what kind of air conditioner and solar panel you have installed.

    Solar Panels for Air Conditioning Units

    When we talk about appliances being powered by solar energy, we often refer to solar panels as the primary supplier.

    Through harnessing the sun’s natural energy, solar panels provide AC power to our appliances, providing a safe, renewable energy source.

    The benefits to using this energy over something like burned fossil fuels are it reduces your carbon footprint, and you won’t constantly need to fill up on gas.

    In terms of what you can power with solar panels, the sky’s the limit. But, aside from air conditioners, people wonder how many solar panels to charge an electric car and other power-hungry appliances.

    Solar panels, in general, are just a really good investment, especially if you stay in an area with hot humidity and plenty of sunlight.

    For your appliances at home, determining how many solar panels I need to power up the appliances isn’t too complicated as they pull a constant current.

    environmental, sustainability, innovation, leading

    In other words, once you know the power rating of an appliance in watts, you can find a solar panel that matches the wattage.

    Appliances like fridges, freezers, and air conditioners aren’t as simple, however, due to them containing motorized compressors.

    This means that the power they draw would vary and need to be averaged out.

    An air conditioner would need around 1,200 watts of solar panels for each ton of cooling capacity. This is assuming the solar panel is exposed to 4 peak-sun hours per day.

    Battery Packs

    If you want to use a battery instead of an inverter, a 100Ah battery is recommended per ton for each hour anticipated during the air conditioner’s running time.

    The benefit of this is that it’ll allow your solar panel to power up your air conditioner when irradiance is low and provides a reservoir to supply the motor surge current.

    Solar panel systems that are designed to run home appliances make use of an inverter to change the DC voltage produced by solar panels into usable AC for domestic use.

    When we talk about a ton in air conditioning ratings, it’s a value representing the amount of cooling necessary to freeze 2,000 pounds of ice in one day.

    Veterans in the world of air conditioning refer to it as a “short ton span.”

    The bigger the value of the tonnage, the more air can be cooled each hour.

    One ton is represented as 3.5 kW (kilowatts), meaning that a one-ton air conditioning unit will have a wattage of 3,500. If you figure out the kilowatts, you know how to calculate solar panel output in watts.

    Both air conditioners and solar panels have a rule of thumb guideline for sizing the system. For instance, one of these rules states that an air conditioning unit will pull around 7A for every 1 ton of its cooling capacity.

    However, this will change as the tonnage changes.

    How Much Power Does an Air Conditioner Use

    Every air conditioner uses a different amount of power. Therefore, to determine the power consumption, the BTU (British Thermal Unit) is an important variable in our calculations.

    Let’s compare three different air conditioning units with three different BTU ratings.

    A 5,000 BTU AC uses around 500 W, a 10,000 BTU unit uses around 1,000W, and a 15,000 BTU conditioner uses around 1,500W. Notice how there’s a 500W jump between them?

    This constant jump remains mostly true, with it only differing from 100W on the days where it’s not constant.

    environmental, sustainability, innovation, leading

    In terms of amps, it’s a bit different. A 5,000 BTU AC will run at around 41A if it’s plugged into a 12V battery hooked up to a solar panel.

    If we use the same system we used in the previous test, the 10,000 BTU air conditioner will run at around 83A while the 15,000 BTU air conditioner will run at around 125A.

    Questions to Ask Yourself

    There are a few questions you need to ask yourself before you can build a solar system to power an air conditioner.

    • How long will the air conditioner be running?
    • Are batteries required to run your air conditioner? And if so, what type of battery is best suited for the solar system?
    • What’s the size of your solar panel?
    • Do you have an inverter?

    Answering these questions before we can think about hooking up our solar panels to an air conditioning unit is critical in ensuring that everything runs smoothly.

    Choosing to run your air conditioning unit using solar panels will also save you a good amount of money as ac units are responsible for a large amount of power consumption.

    environmental, sustainability, innovation, leading

    Checklist to Know How Much Solar Power You Need

    The size of your solar panel or solar array solely depends on how much energy you intend to use daily.

    If you want to use a battery, the size of the battery bank depends on how many days you want your energy storage to last during cloudy days.

    The charge controller you need should properly manage the energy between your solar panels and battery banks.

    Lastly, the inverter you need depends on what appliances you want to run off your system, and in this case, we want to power an air conditioner.

    To know how to size out these components, you need to make a checklist of every appliance you plan to power. This is done by reading the power consumption rating found on the appliance and the output rating.

    If you have the volts and amps, simply multiply them together, and you will have the appliance’s wattage.

    Once you have the wattage of your air conditioner along with any other appliances you may want to power, list the amount of time you spend using them each day in hours.

    We then take the output wattage and multiply it by the hours, and voila, we have a measurement called watt-hours.

    If you just want to figure out the watt-hours of your air conditioner, multiply the two values and see how it relates to your solar needs.

    We don’t want a solar panel that performs under our required watt-hours, so you must do proper research before purchasing a brand and installing a brand new solar panel.

    How Many Solar Panels to Run AC

    All air conditioning units have different efficiency ratings, meaning if we used their electrical kilowatt ratings as a comparison, it wouldn’t reflect their cooling power.

    In other words, if we have 2 AC units that are rated at 1.5 kW, there’s a strong chance that they might not have the same cooling power.

    For this, we look at the energy efficiency ratio, telling us how well an air conditioning unit cools.

    The EE rating system is based on an outdoor temperature of 95 degrees Fahrenheit and an inside temperature of 80 degrees Fahrenheit.

    We need to take the air conditioner unit’s British thermal unit (BTU) and divide it by the electrical rating of the unit in Watts. After this, you will be left with a ratio that’ll indicate the efficiency of the ac.

    If you have an air conditioning unit that has an EER of 11, it falls under the category of being an efficient AC.

    Anything below 11 and around 10 is recommended for countries or locations that experience hot, humid climates.

    SEER Ratings

    Another power rating that people in the ac market look at is the SEER rating. This takes into account an air conditioner’s cooling capacity over a range of outside temperatures instead of fixating on one or two specific values.

    The S in SEER means that the ratings are seasonal.

    When the motor inside an air conditioning unit starts up, it pulls more current than when it runs continuously.

    The value of the running current is always dependent on the load, but the surge, also known as the inrush current, is the highest amperage that the motor pulls.

    Surge currents only last for a few seconds, and the heating effect on the wiring isn’t too drastic or significant.

    However, your breakers and fuses would need to be sized accordingly so that they can accommodate a random surge without causing a power trip.

    This has important implications for a solar system wanting to run an air conditioning unit.

    For example, if your ac is running during the day without a battery being used as an energy reservoir, the solar panel’s wattage rating would need to be big enough to supply the motor surge current of the ac.

    Now that we’ve explored what happens in an air conditioning unit on the load side, we can investigate the supply side in depth.

    Solar Panel Options

    If we are using a 200-watt solar panel from Shop Solar Kits to power a 100W air conditioning unit, simply having one of these panels will be more than enough.

    Keep in mind that these 100W air conditioners are small and are typically fitted onto a room’s window to keep a room cool.

    If you use a weaker solar panel such as 100W one, then having an array of 2 to 4 solar panels will be sufficient.

    Whatever the wattage of your ac unit, always ensure that your solar panel matches it. If it doesn’t, put together an array of solar panels until their total wattage exceeds the wattage of the ac unit.

    But we need to look at the bigger air conditioning units that will require more power.

    Let’s say we have an air conditioner that uses 4.9 Amps at around 115 volts. To get the wattage, we multiply those two values together, getting around 564W per hour.

    The average running time for an ac during the day is 8 hours or a third of the day.

    We would need over 2100 watts of power to keep a 565-watt air conditioner powered because we have to go with an off-grid solar panel that uses batteries.

    If you want to run this air conditioner unit purely off of solar, you want to have that excess power stored in batteries.

    However, if you have a grid-tied system where you are feeding power into the grid, the solar panels won’t work after a certain time. This will leave you powering your ac off the grid overnight and if it’s overcast.

    Another factor to consider is that you need so much power during those limited sun hours each day to provide enough excess power above and beyond the wattage on the ac.

    Using the batteries will ensure that you have enough power to last you all day and night.

    200W Solar Panel Review

    While there’s no specific solar panel designed for an air conditioning unit or system, we recommend Shop Solar Kit’s 200w solar panel if you want to power up a smaller ac.

    For a central air conditioning unit, you want to ensure that you have an array made up of these solar panels.

    This monocrystalline, high-efficiency solar panel is built to last and can power up your batteries, appliances, and, most importantly, your 100W air conditioning unit.


    Air Conditioning units aren’t the prettiest sight to behold when stacked up on the outside of your house, so having a solar panel that doesn’t look too pretty won’t do your home any good.

    Fortunately, the 200W solar panel from Shop Solar Kit is a matte black design with an aluminum frame.

    It comes with pre-drilled holes compatible with ground mounts and Z brackets, making it easy to install anywhere you please.

    The solar panel weighs in at around 27 lbs, making it easy to pick up and carry should you need to relocate.

    In terms of dimensions, we are looking at a 58x26x1.4-inch design, and these measurements, paired with the solar panel’s light design, make it easy to install on top of an RV.

    This also gives you an idea of how many solar panels per acre you would need if you wanted to expand and add more.

    The rigidness of the solar panel makes it built to last, being able to withstand challenging environmental conditions and ensuring that you get your money’s worth.


    Staying true to its name, this solar panel has a maximum power output of 200W. It also has a maximum voltage of around 21V with a current of around 10A.

    Outside of an air conditioning unit, you can power anything that doesn’t exceed the total power output of the solar panel.

    But staying true to the topic of air conditioners, this solar panel can go on the road with you to power your RV’s ac.

    However, an RV’s air conditioning system will be more than a 100W air conditioner you use in your room. So, it’ll be best to have an array on top of your RV.

    Who Is It For

    This solar panel is geared toward those wanting to power a smaller air conditioning system that doesn’t use an excessive amount of power.

    These units are priced at around 240, giving you a lifetime of customer support and a 25-year limited power output warranty.

    To put that price into perspective, the average price is around 10/square foot wanted to know how much solar panels cost per square foot. So you are getting a pretty good bang for your buck.

    Solar Panel For Air Condition (Here’s How)

    Solar panels for air conditioning units are a great way to power your house in an environmentally friendly way. Instead of burning fossil fuels to power your house, car, or outdoor space, using solar panels is a ‘green’ method that can provide you with the same benefits as any other power source.

    Not only do individuals spend an excessive amount of money on air conditioning, but energy consumption is directly harmful to the environment.

    Sources have shown that air conditioning causes upwards of 117 metric tons of CO2 released into our atmosphere – so how can we combat the ever-rising of air conditioning and the emissions of greenhouse gasses?

    By using solar panels for air conditioning, individuals can find eco-friendly ways to power anything they need – whether it be homes, sheds, window units, or cars.

    Here are some of the key points that I’ll cover, plus some more crucial information that will help your air conditioning decisions in the future:

    • Is solar air conditioning right for you?
    • Best solar power units for 2022
    • Pros and cons of solar power air conditioning units
    • How to use solar power air conditioning in cars, sheds, and window units

    If you are an eco-conscious individual who sees how the constant consumption of fossil fuels and energy is ruining the world as we know it, using solar power air conditioning in your life can not only make you feel better, but it can help save the environment.

    Is Solar Air Conditioning The Right Choice For You?

    In short, yes. Solar air conditioning is a technological process that harnesses solar energy from the sun via solar panels to produce air conditioning, central heating, ventilation, or an entire HVAC system for your personal space.

    There are two main types of solar air conditioning to install and use in your home – solar photovoltaic air conditioners and solar thermal air conditioners.

    Solar photovoltaic air conditioners, also known as solar PV air conditioners, are systems that operate in the same way as your traditional air conditioning system. The unit gathers energy from the solar panels to provide power to the entire grid.

    Homeowners who are interested in using solar air conditioners will need to do the correct calculations to ensure they install enough solar panels to power the entire grid system.

    Solar thermal air conditioners use collectors to heat a liquid in the grid. The process of heating, evaporating, and condensing the liquid generates energy to produce cool air-conditioned air for your home.

    Is Solar Air Conditioning Worth The Installation Of New Products And A Potentially Higher Price At The Onset?

    Yes. Solar air conditioning will actually save homeowners money in the long run by cutting down on energy bills.

    However, individuals who are considering using this green method must keep in mind that the refund/payback period for the solar panel air conditioning system can vary based on the size of the grid, the energy usage, and the solar PV/solar thermal system.

    • The amount of money you can save depends on three factors – the size of the solar panels, the capacity of the batteries, and the amount of power usage of the air conditioner.
    • Although the new technology is very costly upfront for items like converters, batteries, solar panels, and new wiring, the long-term energy savings are worth the initial investment.

    Furthermore, if your house has limited roof space, you can still use solar panel air conditioners to power your home.

    In this case, consider using a smaller solar panel air conditioner unit to utilize renewable energy, save money on energy bills, lower your power consumption, and help the environment.

    The bottom line, if your location suffers from extreme heat for a few months per year, solar panels for air conditioning are worth the money you would pay for the electricity to run them. Electric is not cheap and it’s not getting cheaper!

    Facts About Solar Air Conditioning

    Still not sold on using solar air conditioning? Understanding more about how this system works in your house can help you decide whether or not it is the right choice to power your home.

    • You may not need as many solar panels as you thought – Some homeowners think they need to purchase dozens of solar panels to provide power to the entire fire.
    • However, they will be happy to know that they do not need to spend tens of thousands of dollars on a whole room full of panels.
    • Instead, homeowners just need to calculate how many watts the solar air conditioner uses and how many solar panels are required to meet the watt necessities.

    Can I Run An Air Conditioner On Solar Power?

    Yes – homeowners can use three types of solar power to run an air conditioner – DC-powered solar air conditioners, AC-powered solar air conditioners, or hybrid-powered solar air conditioners.

    • DC Powered – DC-powered solar air conditioners use electricity via a solar panel directly connected to the apparatus. Since these units can run through batteries, they can run off-grid – meaning they do not need any internal AC power.
    • The main benefit of using DC-powered solar air conditioners is they are easy to use, simple to install, compatible with full off-grid living, and conducive to powering an air conditioner.
    • The only disadvantage of using the DC-powered solar air conditioner is that they can be very costly to run using only batteries.
    • The benefits of using AC-powered solar air conditioners are they can be used in tandem with grid power, they can be used as a hybrid source of power, and they are compatible with net metering.
    • The benefits of using hybrid-powered solar air conditioners are that they are more cost-effective, alternate between solar and grid power, and flexible to use during all times of the day or night.

    For specific details on how you can run a 1.5-tonne air conditioning unit with solar panels, check out our article here for the full details.

    Pros And Cons Of Solar Power Air Conditioning Units

    There are pros and cons of using solar power air conditioning units vs. other non-renewable energy sources.


    • Decreased utility costs – Since you are using energy from the sun, you don’t need to supply energy from another source.
    • Doesn’t need to be connected – Some solar-powered air conditioners don’t need to be connected to anything to use – they are completely off-grid. This increases the versatility and flexibility of these systems so you can continue running appliances when energy is not available.


    • Might not work at night – Some solar power units may not work at night when there is no solar power to use.
    • Not usable in every state – If you live in a state where solar power is not acceptable, like Florida, you cannot reap the benefits of reduced energy usage.

    Where Can I Use My Solar Powered Air Conditioner?

    One of the main questions that users have when it comes to using solar panels air conditioners is where can I use them? Do they need to be used only for my house?

    You can use solar-powered air conditioners for your car, shed, or window unit.

    Solar Powered Air Conditioner For Car

    It is possible to run your car’s air conditioner using complete AC power. To run your car’s air conditioning on solar power, you need to use a PV panel, battery system, and charge controller to avoid any lost energy during the powering process.

    Some of the main challenges of using solar power air conditioners for your car are the ample power required to run your car, the age, and condition of the car’s engine, the condition of the air conditioning unit, and the car’s AC power requirements.

    If you are thinking of using solar-powered air conditioning for your car, the potential for solar to work can outweigh the potential drawbacks. Sources have shown that using roof-mounted solar panels can increase reflective capabilities and reduce heat conduction.

    Furthermore, solar energy has an infinite potential to provide energy for your vehicle.

    Solar Power Air Conditioner For Shed

    Is it possible to use an air conditioner for your solar shed? Yes – users can install an AC unit to power their shed in the same way you would play solar panels on your home.

    By using a solar kit, owners can decide if they want to use AC power, DC power, or a combination of both. Since all of the components required for the solar power air conditioner will be included in the solar kit, shed owners can install the components on their own.

    The main components of a solar kit that are required to install a solar power air conditioner for a shed include the solar collector panels, charge controller, battery, inverter, AC outlet, and light.

    • The solar collector panel will convert the sun’s energy to the DC current.
    • The charge controller prevents battery damage during the energy collection process.
    • The inverter converts DC to AC power.
    • The battery contains DC electricity for added power storage.
    • The AC outlet can be used to recharge tools inside of the shed.
    • The DC light can help preserve the battery and avoid running out of energy during low-solar days.

    Solar Power Air Conditioner Window Unit

    One of the other most popular places to use a solar power air conditioner is for a portable unit. In some houses, homeowners need a solar air conditioning unit to run for 8 hours a day.

    To figure out how much solar energy is required to power the house, homeowners can multiply the air conditioning unit wattage by the number of hours.

    One thing that homeowners must keep in mind when using a solar power air conditioner window unit is that DC-powered air conditioners require more money and technology than an AC unit.

    An alternative to using a fully DC-powered unit is a hybrid solar-powered air conditioner unit that runs on solar power and AC power.

    For specific details on how you can run a 1.5-tonne air conditioning unit with solar panels, check out our article here for the full details.

    What Problems Do Solar Panels Solve?

    In environmental terms, solar panels can potentially solve a handful of problems, including;1. Air pollution2. Water pollution3. Greenhouse gases4. Reduction in fossil fuel use

    For individuals, solar energy allows you to become completely self-sufficient when it comes to your electricity needs and can save you a lot of money in the long run.

    What Are 3 Important Uses Of Solar Panels?

    The three most important uses of solar panels are;1. Solar electricity. This can be used to power almost any appliance in your home, including TVs, computers, and fridges.2. Lighting. In addition to the use of low-power, LED lightbulbs, solar panels can provide an efficient, low-cost, and environmentally friendly way to provide lighting to homes. 3. Portable solar. In our modern, always-connected lives, our phones, tablets, and computers are almost always with us, and all run on batteries. Portable PV chargers can help keep our batteries topped up no matter where we are, as long as there is some sun to charge them.

    Do solar panels give you free electricity?

    Once the cost of the array is paid in full, the energy it produces is free. There are ongoing maintenance costs, too, such as annual panel cleaning, etc.

    How much will my electric bill be with solar panels?

    Suppose your solar array includes a solar battery backup system, and it is large enough to fully cover your energy usage per day. In that case, your monthly electric bill will be next to zero dollars, even with a grid-tied system.

    If your solar array does not include a solar battery backup system, then at night, your house or business will use grid electricity. That cost will vary but expect to pay from 1/3-2/3 of your average electric bill, and that cost will fluctuate seasonally.

    Do you save money with solar panels?

    The simple answer is, Yes, you save money with solar panels. There is an initial upfront cost, but since solar panels are warrantied for 25 years, you will save money over time. You will also begin to see monthly savings in energy bills, but there are other ways that solar panels pay you back. Those include:1. Adding value to your home or commercial building 2. Monthly decreases in energy costs3. The ability to add more energy appliances without increased monthly costs4. The potential for tax credits for going solar

    Can solar panels power a house 24-7?

    Most definitely! Solar panels can certainly power a house 24-7, with the addition of a high-quality inverter and a suitable battery bank, of course. To power, a house under normal usage will require a massive solar array, though, and there will be a very expensive initial financial outlay.

    Do I need to tell my energy supplier I have solar panels?

    This depends on where you live, but in most cases, it’s not necessary to inform your energy supplier that you have solar panels. That said, you may be producing excess power with your solar system, in which case you may be able to sell that excess power back to energy companies.

    In this case, you’ll naturally need to be in contact with them.

    What Are Solar Cells Known as and Why?

    Solar cells are also called photovoltaic (PV) cells. They are called so because the term ‘photovoltaic’ literally means light i.e. photo and electricity i.e. voltaic.

    These cells generate electricity through the photovoltaic effect. This effect basically causes the generation of free electrons from the semiconducting silicon material of the solar panel when sunlight hits its surface.

    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.

    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.

    Solar Powered Air Conditioning Options

    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
    • AC-Powered Solar Air Conditioners
    • Hybrid Powered Solar Air Conditioners

    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. over, 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.


    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 Cost of Solar Powered Air Conditioners?

    Installation costs of solar-powered air conditioners can be a bit varied. The exact amount depends on the number of air conditioners, the number of solar panels required, and a few other variables.

    Solar-powered air conditioners can cost 2000 before installation while around 5000 including installation. However in some cases, though, this can gain you a 26% tax credit to bring your costs down. Just keep in mind that this will come down to 22% in 2023 and will end in 2024.
