Solar energy is all the rage these days, and with good reason. With the promise of clean, renewable energy, homeowners are looking to reduce their carbon footprint while saving on energy bills. But can you run an AC unit with solar panels? 

The short answer is yes, you can! Depending on the size of your solar array and home electricity needs, you may be able to power your AC entirely with solar energy. Even if you merely supplement your power supply with solar panels, this investment is sure to provide year-round energy savings.

How to Run an AC Unit with Solar Panels: The Basic Setup

Installing solar panels to run your AC involves strategically setting up an inverter, a battery and the solar panels themselves. Since solar panels generate direct current (DC) power, and your air conditioner runs on alternating current (AC) power, you鈥檒l need an inverter to facilitate this conversion.

Choosing the Right System

There are many possibilities when it comes to powering your AC with solar energy, and choosing the right system for your needs is vital. Here are some options:

An On-Grid System

When you stay connected to the grid, your solar panels and an inverter are installed alongside your existing AC unit. Everything is connected to the municipal power supply, so a battery is not required, keeping your initial costs down.

However, if you want to use solar-generated power at night, you can install an optional battery. Just be aware that grid-tied solar panels don鈥檛 work during a power outage, even with a battery. Allowing them to draw power when the grid is down would be dangerous for your home鈥檚 wiring and utility workers alike.

An Off-Grid System

If you鈥檙e looking for complete independence, an off-grid system could be right for you. You鈥檒l definitely want to install solar batteries to enjoy power at night and on cloudy days. Because they鈥檙e less reliable than on-grid setups, off-grid installations are typically reserved for recreational vehicles and homes in remote areas.

Solar-Powered Air Conditioners

Ideal 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 conditioning units use an inverter, allowing them to run on grid power if solar generation is low. Then, hybrid units toggle back and forth between the solar array and grid, depending on the energy production and your home鈥檚 electrical needs.

What to Consider Before Running an AC with Solar Power

Embracing solar-powered air conditioning isn鈥檛 just eco-friendly; it鈥檚 a smart way to save money. However, it鈥檚 important to consider several factors before finalizing your decision.

Up-Front Investment

Solar panels and solar-powered air conditioners require an initial investment. Be sure to weigh this against the long-term savings, keeping in mind that an entire solar panel array typically provides quicker ROI than a solar-powered AC unit. Panels are also more flexible, allowing you to power other appliances with clean energy.

Solar panels may also qualify for the , making your up-front investment more affordable. The credit is set to taper down starting in 2033, but until then, you can enjoy a 30% tax credit on new solar panels installed in residential settings.

Geographical Location

Hot southern climates require more air conditioning, but solar panels in these regions tend to generate more power thanks to the long, sunny days. If you live in a cloudier region, your solar panels will harvest less energy, but your cooling demands may also be lower.

AC Unit Size

Your AC鈥檚 tonnage determines its power consumption, affecting how much solar power you need to run it. Larger homes typically need more air conditioning and consume more power in other ways, potentially requiring you to install more panels.

How Many Solar Panels Does It Take to Run an AC Unit?

Determining the number of solar panels you need depends on the factors outlined above, plus area placement, solar panel type and overall efficiency. The average household air conditioner is around 3,500 watts, and a typical solar panel generates 250 watts. In this example, you would need 14 panels just to run the air conditioner.

Of course, installers size solar arrays to offset the energy consumption of the entire house, not just the air conditioner. So, if you also plan to power electrical appliances, devices and lights that run on other circuits, these components also affect the exact number of panels you need.
