Solar panel suitability: 60-cell for residential, 72-cell for commercial
Solar panels are an essential component of any solar energy system, and choosing the right type of panel is crucial for optimising energy output and efficiency. Two of the most common types of solar panels on the market today are 60-cell and 72-cell panels, which differ in terms of their dimensions, weight, installation requirements, and suitability for different applications.
60-Cell Solar Panels
60-cell solar panels are typically built with six cells wide and ten cells tall, making them relatively compact in size. These panels are lighter and easier to install compared to 72-cell panels, which makes them a popular choice for residential installations. 60-cell panels are often used in rooftop installations, ground mounts, and carports, especially when space is limited. Additionally, the lighter weight of these panels can result in lower labour costs for installation.
One example of a 60-cell solar panel is the SunSpark 335-watt panel, which has a small footprint and an attractive black-on-black design. These panels are durable and highly efficient, making them well-suited for residential use. They also come with a 25-year power warranty and a 10-year product warranty, ensuring long-term performance and reliability.
72-Cell Solar Panels
72-cell solar panels are larger than 60-cell panels, featuring an additional two rows of cells that make them taller. This increased size can make them more challenging to fit on standard residential roofs, but they are highly efficient in utilising space. 72-cell panels tend to be more commonly used for commercial or large-scale projects, as they can generate the same amount of electricity with fewer panels installed. This results in reduced equipment and installation costs for large-scale applications.
The higher cell count in 72-cell panels can lead to higher wattages and power output compared to 60-cell panels, although this is not always the case. The power output depends on the quality and durability of the solar cells themselves. 72-cell panels are available with monocrystalline and multicrystalline technologies, with the latter offering efficient performance at a lower price per watt.
Parallel Usage
While 60-cell and 72-cell panels are typically used independently, some users have explored the possibility of pairing them in series or parallel configurations. In one scenario, an individual with a mixture of 60-cell and 72-cell panels considered wiring them in series to avoid paralleling panels of different voltages. However, ensuring matched currents and independent Vpp can be challenging, requiring additional equipment or modifications.

Installation costs: 72-cell is cheaper on a large scale
The installation costs of 72-cell solar panels are indeed cheaper on a large scale. This is due to a variety of factors, including the number of panels required, racking, and labour.
Firstly, 72-cell panels are larger than 60-cell panels, with the same width but an additional two rows of cells, making them taller. This means that for large-scale installations, fewer 72-cell panels are needed to generate the same amount of electricity as 60-cell panels. For example, if your mounting space is 35' wide and 10' tall, you can install more power by using 72-cell panels to accommodate the taller panel size.
Secondly, the use of fewer panels leads to a reduction in racking, a necessary component for mounting the panels. While thicker rails can be purchased, standard racking options are typically sufficient for both panel sizes, and 72-cell panels may even save money on racking due to their width, which is the same as that of 60-cell panels.
Thirdly, labour costs may be reduced for 72-cell panels in large-scale installations. Although 72-cell panels are bigger and heavier, cranes are often used to lift the equipment to rooftops, making the extra size and weight less of an obstacle. Additionally, the number of electrical connections and clamps required to secure the panels in place is reduced with 72-cell panels, further simplifying the installation process.
It is worth noting that 60-cell panels are more common for residential installations due to their lighter weight and ease of installation, which can result in lower labour costs. However, 72-cell panels are not exclusive to commercial applications, and residential customers can also benefit from their advantages.

Power output: 72-cell panels can have higher wattages
72-cell solar panels have more photovoltaic cells and are therefore larger than 60-cell panels. They are typically about 12 inches taller and weigh about 10 pounds more. Because of their larger size, 72-cell panels can have higher wattages and power output than 60-cell panels. This is because more solar cells can be installed, which means that fewer panels are needed to generate the same amount of electricity. This results in less racking equipment and lower installation costs.
However, it is important to note that the power output of a solar panel is not solely dependent on the number of cells it has. The quality and durability of the solar cells themselves play a significant role in determining power output. For example, a 60-cell panel can have a higher power output than a 72-cell panel if the 60-cell panel has more efficient solar cells.
The mounting space available is also an important consideration when choosing between 60-cell and 72-cell panels. If there is limited mounting space, 60-cell panels may be a better option as they are smaller and can fit into tighter spaces. On the other hand, if there is ample mounting space, 72-cell panels can provide more power output with fewer panels.
Additionally, 60-cell panels are generally lighter and easier to install, making them more popular for residential installations. They are typically used in rooftop installations, ground mounts, and carports. 72-cell panels, on the other hand, are commonly used for commercial or large-scale projects as they can be more cost-effective on a large scale due to the reduced number of panels and racking equipment required.
In summary, while 72-cell panels have the potential for higher wattages and power output due to their larger size and higher cell count, the power output of a solar panel is influenced by various factors such as the quality and efficiency of the solar cells, the mounting space available, and the specific requirements of the installation.

Size: 72-cell panels are 12 taller and weigh more
The size of solar panels is an important consideration when planning an installation. 72-cell panels are 12 inches taller than 60-cell panels, and they also weigh more. This extra height can make a big difference when designing a solar system.
The height difference between 60-cell and 72-cell panels is due to the number of rows of cells each panel type contains. 60-cell panels are typically built with six cells in width and ten cells in height, while 72-cell panels have the same width but feature an additional two rows of cells, making them taller.
The taller 72-cell panels can be advantageous in certain installation scenarios. For example, if your mounting space is 35 feet wide and 10 feet tall, you can install a row of ten 72-cell panels to increase power. In this case, the taller 72-cell panels provide more power in the same space.
However, if your mounting space is more limited, such as only 6 feet in height, you would need to use 60-cell panels as the taller 72-cell panels would not fit. Additionally, the extra size and weight of 72-cell panels can be a disadvantage in some situations. For instance, if you are installing panels on a roof, the larger and heavier 72-cell panels may require more people to handle and could increase labour costs.
In summary, while 72-cell panels offer the benefit of increased power in the same space due to their taller height, they may not be suitable for all installations due to their larger size and weight. It's important to consider the available space and any potential installation challenges when deciding between 60-cell and 72-cell solar panels. The size of the panel should not limit your mounting options, but it may influence the complexity and cost of the installation.

Mounting: 72-cell panels require the same racking as 60-cell
When it comes to mounting 72-cell solar panels, it's important to understand that they are larger than 60-cell panels. 72-cell panels have more photovoltaic cells, which means they are about 12 inches taller. Despite this difference in size, both types of panels have the same width, typically measuring around 40 inches.
The width of the panels is crucial when it comes to mounting because the rails used for mounting are placed across the width of the panel. Since 60-cell and 72-cell panels share the same width, they will require the same amount of racking material for mounting. This means that the standard racking options available in the market will work for both types of panels.
It is a common misconception that 72-cell panels require heavier-duty racking because they are larger and heavier. However, this is not the case, and thicker rails are generally only recommended for areas that experience extreme weather conditions like hurricanes or heavy snow. In most cases, 72-cell panels can be mounted using the same racking as 60-cell panels, and they may even save you money on racking due to the reduced number of panels needed.
While 72-cell panels are typically used for commercial installations due to their higher wattage and power output, they can also be mounted in residential settings if the space allows. When deciding between 60-cell and 72-cell panels, it's important to consider factors such as mounting space, cost, aesthetics, warranty, efficiency, and durability.
