Is it Possible to Run an Air Conditioning System with Solar Panels?
Solar energy is extremely popular as of late, and with good reason. With the promise of clean, renewable energy, homeowners are looking to minimize their carbon footprint while saving on energy expenses. But can you power an AC unit with solar panels?
The short answer is yes, you are able to do that! Depending on the size of your solar setup and home electricity needs, you might be able to power your AC completely with solar energy. Even if you merely supplement your power supply with solar panels, this investment is likely to create year-round energy savings.
The Basics: Ways to Use Solar Power to Run an Air Conditioner
Relying on solar panels to run your air conditioning system involves strategically setting up an inverter, a battery and the solar panels themselves. Given that solar panels produce direct current (DC) power, and your air conditioner runs on alternating current (AC) power, you’ll need an inverter to assist in this conversion.
Selecting the Ideal System
There are many options when it comes to powering your AC with solar energy, and finding the proper system for your needs is vital. Here are some options:
Using an On-Grid System
When you stay connected to the grid, your solar panels and an inverter are put in alongside your current air conditioner. Everything is connected to the municipal power supply, so a battery is not required, helping keep your initial costs down.
However, if you want to use solar-generated power in the evening, you can install an optional battery. Just realize that grid-tied solar panels don’t work during a power outage, even if they are connected to a battery. Permitting them to draw power when the grid is down would be risky for your home’s wiring and utility workers alike.
The Off-Grid System
If you’re searching for complete independence, an off-grid system might be right for you. You’ll certainly want to install solar batteries to use power at night and on cloudy days. Due to the fact they’re less reliable than on-grid setups, off-grid installations are usually reserved for recreational vehicles and homes in isolated locations.
Solar-Powered Air Conditioning Setups
Perfect for off-grid use, DC systems are wired directly to your solar panels, with optional battery operation available. On the other hand, alternating current air conditioners use an inverter, allowing them to run on grid power if solar generation is low. After that, hybrid units switch back and forth between the solar array and grid, depending on the energy production and your home’s electrical needs.
Things to Know Before Running an AC with Solar Power
Embracing solar-powered air conditioning isn’t just eco-friendly; it’s a clever way to save money. That said, it’s crucial to consider several factors before wrapping up your decision.
Primary Investment
Solar panels and solar-powered air conditioning systems call for an initial investment. Be sure to balance this cost against the long-term savings, keeping in mind that a complete solar panel array typically provides quicker ROI than a solar-powered AC unit. Panels are also more flexible, permitting you to power other appliances with solar energy.
Solar panels may also qualify for the solar energy system federal tax credit, which makes your start-up investment more affordable. The credit is set to wind down starting in 2033, but until then, you can benefit from a 30% tax credit on new solar panels installed in residential settings.
Geographical Location
Hot southern climates call for more air conditioning, but solar panels in these regions normally generate more power thanks to the long, sunny days. If you reside in a cloudier region, your solar panels will harvest less energy, but your cooling needs may also be lower.
The AC Unit’s Capacity and Power
Your AC’s tonnage dictates its power consumption, affecting how much solar power you need to run it. Bigger homes usually need more air conditioning and require more power in other ways, perhaps requiring you to install more panels.
How Many Solar Panels Do You Have to Buy to Run an Air Conditioning System?
Identifying the number of solar panels you will need depends on the factors discussed above, plus area placement, solar panel type and overall efficiency. The standard household air conditioner is around 3,500 watts, and a basic solar panel generates 250 watts. In this particular example, you would need 14 panels just to power the air conditioner.
Obviously, installers size solar arrays to offset the energy consumption of the entire house, not merely the air conditioner. Therefore, if you also intend to run electrical appliances, devices and lights that run on other circuits, these components also impact the exact number of panels you need.
