You can power an AC or air conditioner with solar power using panels, batteries, and an inverter. The power and size of the AC determine the number of solar panels required to provide power to the system.
Do you want to reduce electricity bills and save the environment by using renewable alternatives?
Follow my website to get interesting facts and suggestions.
Using solar power as an alternative to on-grid electricity offers you yearly or seasonal energy savings (Of course! It depends on the location you reside in) while decreasing the carbon footprint of your home.
How Do You Run an Air Conditioner Using Solar Panels?
You need an inverter, batteries, and solar panels to run solar-powered air conditioners in your residential or commercial premises.
Please note that solar panels generate DC (direct current), and your air conditioner runs on AC (alternating current) power, so you need an inverter that converts the DC power into AC.
Now, decide whether you want solar air conditioners using on-grid or off-grid power because you have both facilities.
You can also install a completely solar-powered air conditioning system using a solar inverter and batteries, which supply AC power to the system.
Can We Use AC with Solar Power?
You can use an air conditioner with solar power. However, you need to find out the type of AC that fulfills your needs. Please read the following types:
Different Types of Solar-Powered Air Conditioners
If you want to install a solar AC, you have three options. I suggest you use hybrid solar AC because you can run it using on and off-grid power. There are other options like on-grid solar AC and off-grid solar AC.
On-grid Solar AC System
In this case, panels and inverter are to be connected to your AC unit. You need to install panels and connect them to the grid, so batteries are not required to store power. However, if the power goes out, the system will run smoothly because it is not using coal electricity. Do you know the best part of it?
You can run AC units throughout the day using solar energy. Do not need to spend money to keep the temperature cooler, especially if you are working from home!
However, it has a drawback. The solar panels are not connected to solar batteries, so you may not use them at night unless you install a separate battery package, which could be costly!
Off-grid Solar Powered Air Conditioner
In this case, the panels are connected to an inverter and batteries. Since this system is not connected to the grid, your battery can keep the additional power generated by the solar panels. You can use it during the night or on cloudy days when panels cannot get direct sunlight.
DO YOU KNOW?
There are several varieties that include:
- DC (direct current)
- AC (alternating current)
DC units are perfect for use off-grid since they are directly wired to your solar panels and can use batteries. However, if you intend to run your AC in the evening, you need an inverter and battery. Now comes the best option:
Hybrid Solar Air Conditioner System
A hybrid AC unit uses an inverter that converts DC into AC power and is able to use on-grid power when the solar power supply is not sufficient. It is a combination of both on and off-grid systems that I was talking about earlier.
The process is simple!
As a user, you need to connect the AC unit to both the on and off-grid power supply; now, the unit will choose the power supply to run the system.
Now you have understood the types of solar panels, which one is the best and why..
..but it is not all; you need to consider the following things before investing in a solar system.
Things to Consider Before Installing Solar-Powered AC
Solar AC is not cost-effective but an amazing option, especially for commercial premises, because it cuts down on your monthly electricity bills. If your set-up has a backup battery, it is possible to blackout-proof your premises.
Read this, and do not rely on coal electricity!
Before you decide to install solar panels for your AC, the first thing that comes to your mind is installation costs, right?
Though here I cannot offer an average cost, you MUST consider the following aspects to better understand the system:
Purpose of Installing Solar Panels
The upfront installation costs will vary depending on whether you choose to install a completely off-grid solar power system to power your house or use it only for solar AC. While both options provide the same benefits, off-grid solar panels will offer higher ROI because you can use the power for more appliances in your home using green energy.
The Location and Climate
A warmer climate needs more powerful AC, and the unit consumes more electricity. The number of solar panels depends on the location and climate. For example, if you are a resident of Arizona, you need more power for AC than a resident who lives in an upper-Midwest state with more clouds and snow.
The second example can be:
Eastern countries always invest more in air conditioning than western countries because of their climate, average temperature, seasonality, and lifestyle.
Size of Your Premises
Lastly, the installation costs will depend on the size of your premises and the power of the solar AC. Commercial premises need more powerful AC and the latest model than residential premises- so the cost differs!
How Many Solar Panels Do I Need to Run in an AC Unit?
To operate your AC through solar panels, you must make sure panels generate an equal (or more) amount of power. A common estimate is to divide your AC power with the solar panel’s power you want to utilize.
Here is a SIMPLE CALCULATION that you can easily understand:
Based on the typical household AC power of 5000 watts, you need 5000/ 250 W (panels) equals 20 panels.
However, DO NOT FORGET the variables. How much power solar panels generate depends on the climate, location, configuration, type of electrical connections, and much more.
For the most precise details about residential and commercial solar panel installation, you must consult a local solar expert.
Can We Run Solar AC at Night?
You can run solar AC at night using an inverter and batteries. You need separate solar batteries for on-grid solar AC because solar panels are connected to an on-grid supply. They cannot save power in the battery.
For hybrid and off-grid systems, you can use solar batteries to run the system at night without relying on traditional on-grid electricity.
