What is the standard size of a solar panel?
What are solar panels made of?
Solar panels or solar modules are most frequently made of silicon solar cells. Their quantity and configuration in the module determine its size. Individual solar cells are around 6″ x 6″ (or 15 [cm] x 15 [cm]) squares.

Solar Cells Layout
The most common solar cell layouts are:
- 60 cells (6 x 10 layout)
- 72 cells (6 x 12 layout)
The 72 cell modules are usually 1″ (30 cm) taller than 60 cell modules. Additionally, 72 cell modules produce more power than 60 cell modules.
60 cell solar module size is typically around:
- 39″ x 66″
or
- 1.0 m x 1.7 m
72 cell solar module size is typically around:
- 39″ x 77″
or
- 1.0 m x 2.0 m
What are 120 and 144 cell modules (half-cut)?
Half-cut cell modules are made of the same solar cells but they are cut into halves to reduce their resistance. This allows them to produce more power. In this case, the 120 cell modules have the same dimensions as the 60 cell modules, and the 144 cell modules have the same dimensions as the 72 cell modules.
