Standard Solar Panel Sizes

The usual traditional solar panels commonly come in 2 different configurations: 60-cell and 72-cell.

With that being said, the standard dimensions for each option are:

  • 60-cell panels: 39″ x 66″ (3.25 feet x 5.5 feet)
  • 72-cell panels: 39″ x 77″ (3.25 feet x 6.42 feet)

 

Standard Solar Panel Dimensions

Standard solar panels commonly come in 2 different configurations: 60-cell and 72-cell.

An individual solar cell is a 6” x 6” square. 60-cell panels are laid out in a 6×10 grid. 72-cell panels are laid out in a 6×12 grid.

  • 60-cell panels: 39″ x 66″ (3.25 feet x 5.5 feet)
  • 72-cell panels: 39″ x 77″ (3.25 feet x 6.42 feet)

These are the standard solar panel sizes typically for most residential and commercial installations.

How Big Is the Average Solar Array?

The average household uses approximately 867 kwh of electricity each month. It would take a 6.5 kw of solar array to offset the full usage.

With a 60-cell solar panels with a stock range from 285w to 315w, and a stock of 72-cell panels ranges from 335W to 375W. We can figure out approximately how many panels it would take to build a 6.5 kW (6500-watt) system:

  • 6500W / 285W = 22.8 (23 panels)
  • 6500W / 315W = 20.6 (21 panels)
  • 6500W / 340W = 19.1 (20 panels)
  • 6500W / 375W = 17.3 (18 panels)

An average-sized solar system will contain 18-23 panels depending on the efficiency of the panels you use.
