How Big is a Solar Panel?

For beginners, they might wonder “how big is a solar panel”. This is the main question that might arise. For people planning to integrate a solar panel on their home, it’s important to know the size of the solar panel required. In this article, we will have a quick rundown on the solar panel sizes. This will help you have the best value for your money and efficiency.

Traditional Solar Panels

Usually, this kind of solar panels is very common in residential houses. They have sizes that are really tolerable particularly to areas with limited spaces. The 60-cell comes in the size of 3.25 x 5.5 ft. On the other hand, the 72-cell configuration in 3.25 x 6.42 ft. which is suited for bigger houses.

Since some houses have super limited spaces, you’ll have to take note of it prior to buying. With regard to that, the 60-cell might be the one fitted for your needs.

Right now solar panels do have a standardized size. This makes it easier for people to choose the right solar panel for their needs. Those traditional solar panels are good for both residential and business use. 

Bigger Capacities

If you have a bigger home then you might as well consider having a bigger solar panel. One of the most popular mid-sized solar panels is made by Panasonic. It has the following dimensions of 41.5 x 62.6 inches. It is powered by 96-cell panels that are effective in giving your place a decent source of solar energy. 

It is a little bit uncommon to find this kind of solar panel though because it is pretty expensive compared to what we’ve discussed a while ago. However, when it comes to efficiency there is no doubt that it is more reliable. This is because they can accumulate more solar power compared to the lower-end solar panels.

Important Facts about Solar Panel Sizes

For you to determine the right size of solar panels for your needs, you’ll need to learn more about it. So in this portion, we will talk about more facts regarding solar panel sizes.

Usually American household consumes 867 kilowatts per hour of electricity on a monthly basis. In order to reach that a 6.5-kilowatt solar array is expected.

In reality here is the following maximum capacity of solar panels. 

  • 60-cell = 285 to 315 watts
  • 72-cell = 335 to 375 watts

There are several factors to know the number of panels to use in forming a 6.5-kilowatt solar panel project. The chart goes as follows:

  • 23 panels can produce 285 watts
  • 21 panels can produce 315 watts
  • 20 panels can produce 340 watts
  • 18 panels can produce 375 watts

Although those numbers are estimated but mostly close in helping you build a 6.5-kilowatt solar panel system.

Usually, the standard solar panel system will be able to function using 18 to 23 panels. Well, it is pretty obvious that the more panels you have the more power you accumulate. But expect that it is more costly to run in terms of maintenance.

The Efficiency of Every Panel

If you are wondering what is the most and the least efficient panel then we will discuss it here on this part of the article.

For the 375 watts/72-cell it can accommodate up to 375.38 square feet. While the 285 watts/60-cell panel has the ability to accommodate up to 429 square feet.

To conclude, the standard solar panel system can be in the range of 375 to 429 sq. ft. It can be placed on the top of your house or on the ground but make sure that it is mounted. This will ensure that sufficient sunlight will come across the surface of the panels. As a result, better energy efficiency with the use of sunlight will be achieved. 

The Size of RV Solar Panels

Portable solar panels are trending nowadays. There might be a time wherein RV solar panels will be one step ahead of the traditional solar panels. This is because they are mobile, unlike their conventional counterparts. They are very useful as they can be used for multiple things such as:

  • Boats
  • RVs
  • Street lights

They somehow save more space because a 5-watt panel can only consume 1 sq. ft. of floor area. Although, they also come in variations that are pretty normal for solar panels, and mostly they come on 12 or 24 volts. Although, there are new technologies that might take place in the near future for more variations on voltages.

What is the Corresponding Weight of Solar Panels?

If you are about to ask the question of “how big is a solar panel” then most probably weight is also relevant to it. Mostly, solar panels are hefty in terms of weight. This is why you’ll need a sturdy roof for you to accommodate them efficiently. This is also an assurance that your roof will not break down once you integrate your solar panel system in it.

From a factual standpoint, an entire solar panel might weigh in from the range of 40 to 60 lbs. They are pretty easy to lift but the problem lies in their physical shape. Not only that, but they are also very fragile that is why they must be handled with extreme care.


Now we know the answer to the question of “how big is a solar panel”, then integrating one for your home might become easier. This is because you’ll know what type will perfectly fit there without giving you a hard time.
