One of the most important things you need to know before you are going to install solar panels is when it comes to the size of the solar panels, by choosing the best size of solar panels that suits your needs, you can get the maximum power generation efficiency from your solar panels. In this article, we will introduce you to various solar panel sizes to help you choose the right size of solar panel.
The main solar cell sheet sizes available in the market today are 125mm x 125mm, 156mm x 156mm, 158.75mm(G1), 166mm(M6), 182mm(M10), 210mm(G12). Among them, 125mm×125mm and 156mm×156mm have been gradually replaced by larger size solar panels. The current mainstream sizes are 158.75mm(G1), 166mm(M6), 182mm(M10). Solar cells are assembled in parallel or in series on a backsheet, and then the solar panel is composed of the upper and lower shells and the sealing layer in the middle, so it can be said that it is the size of the solar cells that affects the size of the solar panel.
The solar panels made up of these solar cells are 60 cell solar panels, 72 cell solar panels, and 96 cell solar panels.
The 60 cell solar panels are usually arranged in a 6*10 arrangement, the size of these solar panels is 1600*900mm, they are more popular in homes and the power of the 60 cell solar panels is usually between 300W and 450W.
The 72-unit solar panels are offered in a 6*12 arrangement, and their dimensions are 1700*900mm, and generally they are often used in commercial applications, and their power ranges from 400W to 500W.
The 96-unit solar panels have a structure of 8*12, and their dimensions are 2200*1100mm. 96-unit solar panels have a larger size, and their power is also larger, about 600W or more, and generally solar panels of this size will only be used in large-scale power stations.
Different solar panels come in different sizes, which need to be carefully considered when choosing. Although solar panels all function in the same way, it doesn’t mean that all solar panels can generate electricity with the same efficiency. Different brands and systems are going to affect the size of the solar panels. For example, when traveling so the solar panels can’t be too big, but for large power stations the solar panels will be larger. Once you know the size of the solar panels, you will know what their purpose is. Below is a range of solar panel sizes.
The 50W solar panel measures 670*540*25mm and weighs 20kg.
The 100W solar panel has dimensions of 1030*460*30mm and weighs 20.3kg.

Trina Solar 450W solar panel has dimensions of 1762*1134*30 mm and weighs 21.0 kg.
The size of Longi Solar 450W solar panel is 1722*1134*30mm and weight is 20.8kg.
The size of JinkoSolar 450W solar panel is 1762*1134*30mm, and the weight is 21.0kg.
The size of Longi Solar 550W solar panel is 2278*1134*35mm, and the weight is 27.5kg.
The size of JinkoSolar 550W solar panel is 2278*1134*35mm, and the weight is 27.0kg.
The size of LongiSolar 600W solar panel is 2278*1134*30mm, and the weight is 27.2kg.
Trina Solar’s 600W solar panel measures 2382*1134*30 mm and weighs 33.7 kg.
JinkoSolar’s 600W solar panel measures 2465*1134*35mm and weighs 29.5kg.
Trina Solar 700W solar panel size is 2384*1303x33mm, weight is 38.3kg.
When you see a roof full of solar panels, you think about how much the solar panels weigh. How many solar panels can the roof hold? Generally speaking, the weight of solar panels for domestic use is about 19kg to 30kg, and the weight of commercial solar panels is about 22kg to 35kg. However, some brands of 300W solar panels weigh only about 14kg, and lighter solar panels like these would be more suitable for installation on roofs, but they would be more expensive than normal solar panels. So maybe the weight of your solar panel is not within the range we gave, it may be related to the brand of solar panel.
The power of the solar panel: the power of the solar panel is linearly related to the size of the solar panel, generally the larger the size of the solar panel, the more sunlight can be absorbed under the same sunlight conditions, and thus the more electricity can be generated. Therefore, we are able to consider the power of solar panels to be able to the size of solar panels.
Photoelectric conversion efficiency: the greater the photoelectric conversion efficiency of the solar cell slices, the smaller the area of the solar panel needed to generate the same power. That is, when the photovoltaic conversion efficiency of the solar cell is larger, the size of the solar panel can be smaller.
Energy Demand: For a number of different energy outputs, the size of the solar panels you need will vary. If your energy needs are large, but you live in an area where the light intensity is weak, you will need a larger size solar panel to meet your energy needs.
Size of solar panels for home use: The wattage requirement of solar panels for home use is not big, usually from 300W to 550W, so the size of solar panels for home use is 1350*1134*35mm, 1722*1134*30mm, 1762*1134*30mm, 2278*1134*35mm and so on.
Size of commercial solar panels: For commercial solar panels, they are usually installed on the roof or directly affixed to the wall, and the commercial energy requirements will be more. So the size of solar panels will be bigger. The general size is 2278*1134*35mm, 2382*1134*30 mm, etc.
Solar street light size: we usually see solar panels on the solar street light, but because the solar street light is only used at night, so the size of the solar street light used will be smaller, generally 670*540*25mm, 1030*460*30mm and so on.
Caravan solar panel size: caravan electricity will be less than the family power consumption, and caravan roof area was not large, the caravan solar panels are also smaller, generally 1480 * 680 * 35mm, 1350 * 1134 * 35mm, 1980 * 880 * 35mm.
Portable solar panel size: portable solar panels are designed for traveling, so their size is often called small in order to facilitate carrying. Generally used size is 1350*1134*35mm, 1980*880*35mm, 1722*1134*30mm and so on.
Reduced cost: We may mistakenly think that larger size solar panels may be more expensive, in fact, larger size solar panels will be cheaper. For example, a 400W solar panel and two 200W solar panels have the same power, but for two 200W solar panels, they use more aluminium frames than a 400W solar panel and consume more in packaging.
Generation of electricity will be more efficient: Generally speaking, larger size solar panels can absorb more sunlight and thus will also generate more energy.
Generating current will be more stable: Larger size solar panels can reduce the line loss and internal resistance in the solar system, when the internal resistance in the line is reduced, the current generated by the solar panels will be less resistance, which ensures the stability of the current.
There are many sizes of solar panels available in the market, if you choose solar panels after you have understood the approximate size of the solar panels, then you can significantly improve the service life of the solar energy system and the efficiency of power generation in order to achieve energy independence.
