From reducing to eliminating your power bill, energy dependence, and carbon footprint, investing in a more sustainable future is as good a reason as any to get started with solar energy. However, with varied solar panel dimensions, one can get confused. So, in this article, you’ll get a detailed view of solar panel dimensions in mm, cm, and feet and also the varying relation between solar panel sizes and wattage.
Standard Solar Panel Dimensions and Sizes
Since you’ll be spending so much on marketing, it’s essential that you concentrate on what really matters in this transaction. It’s not a terrible idea to get recommendations from people you know, especially if any of them already have the system set up in their own houses. They will give better advice about what solar panel dimensions and sizes you can go for.
Furthermore, you need to choose the panel type you’ll be utilizing. In terms of solar panels, monocrystalline and polycrystalline are the two most common.
However, the higher cost of monocrystalline panels is justified by their superior efficiency. You should go with this variety if you don’t have enough room for a more expansive array of panels.
Contrarily, polycrystalline panels are less expensive overall but don’t perform as well as monocrystalline panels. If you have a lot of room, this may be a good option for you. More panels should be planned for in the near future as well.
There are many different sizes of solar panels, but the two most frequently used sizes are:
A 60-cell solar panel
- 39×66 inches
- 3.25×5.5 feet
A 72-cell solar panel
- 39×77 inches
- 3.25×6.42 feet
By comparing their dimensions, you can observe that the two solar panels differ mostly in length since they are identical in breadth. The thickness of a solar panel is typically 40 mm, and this is true for both 60-cell and 72-cell panels.
What are the Solar Panel Dimensions in mm? What are the Solar Panel Dimensions in cm? What is the Solar Panel Size in Feet?
The cell layout of a 60-cell solar panel is 6×10 (6 columns and 10 rows). The cell layout of a 72-cell solar panel is 6×12 (6 columns and 12 rows).
Standard Solar Panel Dimensions in mm
A solar panel’s wattage and cell design determine its overall physical dimensions and mass. In general, the solar panel dimensions in mm are 156 mm × 156 mm.
Standard Solar Panel Dimensions in cm
The solar panel dimensions in cm are determined by the output of the manufacturer. The size of a solar panel is often not affected by the output.
As discussed, there are two sizes of solar panels, Hence the solar panel dimensions in centimeters would be around,
- 99×167.5 cm (for 60-cell)
- 99×195.5 cm (for 72- cell)
Standard Solar Panel Dimensions in Feet
Having an idea of the major Solar Panel Dimensions and sizes available in the market is a great head start. The solar panel dimensions in feet are,
- 3.25×5.5 feet (for 60-cell)
- 3.25×6.42 feet (for 72- cell)
What is the Relation Between Solar Panel Sizes and Prices?
Before discussing the relation between solar panel sizes and prices it’s important to know the various types of solar panels.
- Monocrystalline Solar Cells: These panels, also called single-crystal panels, are sliced up from a single crystal of pure silicon. The fact that they’re completely black indicates that they’re composed of silicon. Monocrystalline panels are the most durable and efficient because of their usage of pure silicon, and they also take up the least amount of room.
- A Polycrystalline Solar Cell: You can tell they are not made from a single silicon crystal because of the name. Melted silicon pieces are poured into a square mold. Because of this, polycrystalline cells are substantially more cost-effective, and their distinctive square form is maintained.
- Copper indium gallium selenide (CIGS): Thin layers of copper, indium, gallium, and selenium are deposited on a glass or plastic backing to create copper indium gallium selenide (CIGS) panels. As a result of combining these factors, the resulting thin-panel technology has the best efficiency of any currently available technology, however, it cannot match the efficiency of crystalline silicon panels.
- Cadmium telluride (CdTe): Cadmium telluride (CdTe) offers the lowest carbon footprint, water need, and energy payback period of any solar panel technology, yet it costs about the same as polycrystalline cells. However, cadmium’s toxic properties increase recycling costs relative to non-toxic alternatives.
- Amorphous Silicon (a-Si): Due to its shapelessness, amorphous silicon panels (A-Si) were given that moniker. As opposed to monocrystalline and polycrystalline solar cells, these use silicon with no molecular structure. Fewer silicon atoms are needed to create an a-Si cell than are needed to create a conventional silicon cell. By sacrificing productivity, they are able to achieve the lowest possible production costs. As a result, a-Si panels are best for low-power devices like calculators because they consume so little energy.
|Type of Solar Panel||Average Cost Per Watt|
|Polycrystalline||$1 – $1.50|
|Copper indium gallium selenide||$0.60 – $0.70|
|Cadmium telluride||$0.50 – $0.60|
|Amorphous silicon (a-Si)||$0.43–$0.50|
Note that costs per watt might climb to as much as $3.50 when you include them in things like labor and rent.

What is Comprehensive Relation Between Solar Panel Sizes and Wattage?
The part of a solar panel called a photovoltaic cell is responsible for turning sunlight into electricity. Crystalline silicon wafers are commonly used to fabricate these cells. Light from the sun excites the silicon in the cell, setting in motion the flow of electrons that power the cell’s electrical current.
Since the electrical output from a single solar cell is low, the cells are typically combined into modules to increase overall efficiency. Solar panels can have anywhere from 36 to 144 cells. Standard solar panel sizes are 60 cells and 72 cells.
Compared to 60-cell solar panels, 72-cell panels have additional photovoltaic cells, thus the 72-cell panels can also have higher wattages and power output. However, this is not always the case. In fact, you’ll be shocked to know that the number of cells in a solar panel doesn’t have a direct correlation to its power output. The power output of a panel is more dependent on the durability and quality of the solar cells themselves.
For instance, let’s take the example of Axitec’s AC-310P/156-72S. It’s a 310-watt (W) solar panel that has 72 cells. It has more photovoltaic cells than LG’s LG325N1C-A5, which is a 60-cell 325W panel. Despite this, Axitec still has a lower power output.

What are Solar Panel Dimensions in mm, cm, and feet for 300 W and 500W Solar Panel?
Solar panel dimensions can vary with different factors like manufacturing. So, let’s discuss some very common size solar panel dimensions in mm, cm, and feet.
For 300 W and 500 W solar panel dimensions would be as follows:
|Size||300 W||500 W|
|In cm||91.44× 165.1||18.796×9.4488|
With solar technology evolving, the amount of energy harvested from each panel is rising. As solar panel technology improves, fewer panels are needed to produce the same amount of power as they did when they were first installed. Having a smaller solar array with fewer panels can reduce the initial investment and the amount of roof space needed for the installation.
This blog was a basic outline of solar panel dimensions including solar panel dimensions in cm, solar panel dimensions in mm, solar panel size in feet, the relation between solar panel sizes and prices, and the relation between solar panel sizes and wattage.
