60-cell and 72-cell panels can be used in rooftop installations, ground mounts, carports, and more. That being said, 60-cell solar panels are much more common for residential solar installations, while 72-cell solar panels are more commonly used for commercial or other large-scale projects. There are a few key differences between the two that will impact which option you choose, regardless of whether you're installing for your home or business.

Dimensions
72-cell solar panels have more photovoltaic cells, therefore, they are larger than 60-cell panels. When it comes to dimensions, 60-cell panels are usually built six cells wide and ten cells tall. 72-cell panels are also six cells wide but have an additional two rows of cells that make them a bit taller. What does this translate to in feet and inches? 60-cell solar panels have an average dimension of roughly 5.4 ft by 3.25 ft. 72-cell panels will roughly be the same width and average around 6.5 ft in height.
This extra space can make a big difference when it comes to your solar system design. If you have plenty of uninterrupted roof space or a lot of land for a ground-mounted installation, you can likely go with 60 or 70-cell panels. But, if you're going to have limited space for installation or a more complicated layout (such as a lone panel on a dormer or a small garage to fit a few panels), most installers are going to recommend 60-cell panels. Because they're smaller, they'll be able to fit in more tight spaces that may not work for a 72-cell panel. The same is true for roofs that are narrow - if your local jurisdiction or fire department has strict setback codes for solar arrays, 60-cell panels may also be the better option because they are shorter. A lot will depend on the specifics of your roof and your preferences for the layout of your array, so it's a good idea to talk to an installer about your options.
Cost of installing
The cost of installing 60-cell vs. 72-cell panels may also vary a bit for your installation. 72-cell solar panels tend to be cheaper to install on a large scale, which is why they're more common for commercial applications. Because each panel has more solar cells, you can typically install fewer panels to generate the same amount of electricity. Fewer panels mean less racking is necessary, which helps cut down on overall equipment and installation costs.
On the other hand, 60-cell panels are lighter and easier to install, which is why they're more common for residential rooftop installations. This can mean lower labor costs for the installation. For large commercial installations, the extra size and weight of a 72-cell panel aren't as much of an obstacle because cranes are often used to lift the equipment to the rooftop.
Wattage and power output
72-cell panels can have higher wattages and power output than 60-cell panels because of the additional photovoltaic cells, but that's not always the case. In fact, the number of cells in a panel doesn't have a direct correlation to its power output. The power output of a panel is more dependent on the quality and durability of the solar cells themselves.
Let's look at Axitec's AC-310P/156-72S as an example. This is a 310-watt (W) solar panel that has 72 cells. Despite having more photovoltaic cells, the panel has a lower power output than LG's LG325N1C-A5, which is a 60-cell 325W panel.
That being said, if you're looking for the highest wattage panels possible, you do often have to look towards panels with highly efficient solar cells and higher cell counts. Examples of this include LG's LG405N2W-A5, which is a 405W panel with 72 photovoltaic cells. 60-cell panels will rarely get up to 400W (though some can get up to 350W or more)
Short on Time? Here&#;s The Article Summary
This article compares 60-cell and 72-cell solar panels, highlighting their differences and best uses. The key distinction between them is size, with 72-cell panels being larger due to having 12 more solar cells. 60-cell panels are typically used in residential and mobile applications, while 72-cell panels are common in utility-scale projects.
While 72-cell panels are generally rated at higher wattages, the cost per watt is crucial in determining which panel is more cost-efficient. Factors like installation costs also play a role, with 72-cell panels often being preferred for large-scale installations due to requiring less racking material and fewer electrical connections. When choosing between the two, consider your space constraints and budget. 60-cell panels are ideal for limited spaces, while 72-cell panels may be more cost-efficient in certain scenarios. Ultimately, the goal is to maximize your budget and solar power potential.
Introduction
The two most common types of solar panels on the market today are 60-cell and 72-cell. Today, we explain the differences between these two types of solar panels and which one is best for your solar installation.
What is the Difference Between 60-cell and 72-cell Solar Panels?
When it comes down to it, the only real key difference between 60-cell and 72-cell solar panels is size. Solar panels use individual solar cells that you can see as the squares that make up the panel. Obviously, 72-cell solar panels have 12 more solar cells than 60-cell solar panels.
The extra dozen solar cells cause 72-cell solar panels to be larger than the 60-cell solar panels. According to Medium.com, here are the average sizes of these two types of solar panels:
60-cell solar panels are 1.65m (5.41 feet) tall and weigh about 20kg (44.90 lbs).

72-cell solar panels are 1.95m (6.40 feet) tall and weigh about 28kg (61.73 lbs).
For sizing reasons alone, 60-cell solar panels are often used in residential and mobile applications, whereas 72-solar panels are commonplace in utility-scale projects where limited space is not an issue.
Wattage and Power Output of 60-Cell and 72-Cell Solar Panels
It is logical to think that more solar cells imply more solar power, but this is not always the case. Although 72-cell solar panels are generally rated at higher wattages, in some instances, 60-cell solar panels may have more output capacity than 72-cell solar panels. The most important factor in figuring out which solar panel is best for the price is determining the cost per watt.
Let&#;s take a look at two different solar panels. The first is a 300W 60-cell solar panel that costs $200. The second is a 350W 72-cell solar panel that costs $225. The cost per watt of each solar panel respectively would be $0.66 and $0.64. Therefore, if you have room for either type of panel, in this case, the 72-cell solar panel would be more cost-efficient. Although the difference may seem insignificant, accounting for multiple panels over many years, maximizing your cost per watt will lead to the largest financial savings.
Cost of Installing 60-Cell and 72-Cell Solar Panels
In large-scale commercial or utility applications, installers tend to use 72-cell solar panels to save money on installation costs because 72-cell solar panels require less racking material, fewer electrical connections, and fewer security clamps than 60-cell solar panels. Of course, if you boiled these costs down to a residential solar install, there would still be some savings incurred, but at a lower rate.
Your solar panels also influence the rest of your system. If you plan to use micro-inverters instead of one large solar inverter, you will need to make sure that each is appropriately sized for your solar panels, especially when using 72-cell solar panels. Conversely, if you are powering a battery bank, one 60-cell solar panel alone may not provide enough voltage to charge the battery.
Final Words
When designing your solar energy system, either 60-cell or 72-cell solar panels will be best for your needs. If you are strapped for space for your system, for example, on a residential roof, van, or an RV, choosing 60-cell solar panels will maximize the number of panels you can install. If you have space, weigh your options and choose the panel that is most efficient and affordable. After all, when installing solar, the goal is always to maximize your budget and solar power potential!
