I ll get to that but first let s clarify what we mean by size it could mean a number of things.
Reason for standard solar panel size.
The average size of solar panels used in a rooftop solar installation is approximately 65 inches by 39 inches or 5 4 feet by 3 25 feet there is some variation from brand to brand and if you re installing a large scale solar panel system such as for a warehouse or a municipal building your panels will be closer to 6 feet long.
This is exceptional and it offers you the peace of mind you need when you re trying to decide whether or not solar panels are the right choice for you and your family.
This won t cover 100 of the energy your home consumes.
And the size of solar panels for commercial businesses are just the same as the ones we mentioned above.
Pv solar panels tend to vary between 150w to 345w per panel depending on the size of it and the cell technology use to create each of the modules.
How big are solar panels.
Just as in residential cases the size dimension of your system will be determined by the same factors listed in the how much power do i need section.
Whatever the reason could be solar panels are a great move for all sizes of businesses.
To calculate this you ll need to know the size of your roof.
For example panasonic offers 96 cell panels which measure 41 5 x 62 6.
However the standard 60 cell and 72 cell panel sizes are by far the most common in the industry.
If the most standard size solar panels are 17 5 square feet and you have about 385 square feet of roof to install solar panels that will maximize the sunlight consumption you can fit about 22 panels on your roof.
In fact with standard solar panel sizes you can expect that the weight distribution will be roughly two pounds per square foot.
To calculate the number of panels you need divide the hourly energy usage of your home by the wattage of the solar panels.
