What Are The Standard Sizes Of Photovoltaic Solar Panels?

Standard sizes of photovoltaic solar panels

When you are going to do a solar installation, especially on the roof, it is essential to know the exact dimensions of the photovoltaic panels. Here we explain how the size varies according to certain technical specifications.

In the solar panel market there are many models, with different measures depending on their capacity and technology. They usually have the same dimensions, but there are small differences between the different companies.

The dimensions are usually similar. This is due to the size of the solar cells they incorporate, but there is an element of differentiation and it is associated with the fact that there is no exact physical size for each capacity of the panel.

Other influencing factors are the power generated by each panel and the technology used (polycrystalline, thin layer, amorphous, etc.).

 There is only one reference that should allow for row spacing if the panels are sloped using a frame on a flat roof, and you should also note that it should allow 2cm between the panels for brackets.

In general, solar panels are medium in size. They usually have the following measurements:

  • Polycrystalline and monocrystalline panels (maximum power between 230 W and 245 W)

Height 160-170 cm.

Width 90-100 cm.

Thickness 4 – 5 cm.

  • Monocrystalline panels (maximum power between 190 W and 200 W).

Height 130-140 cm.

Width 90-100 cm.

Thickness 4 – 5 cm.

  • Thin film panels (maximum power between 77.5 W and 87.5 W).

Height 120 cm.

Width 60 cm.

Thickness 0.6 – 0.7 cm.

On average 180 – 190 W crystalline silicon panels are 10-15 cm lower and narrower than 230 – 240 W panels.

The most common photovoltaic solar panels generally do not exceed 170 cm in height and 100 cm in width. This means that on a rectangular surface sloping roof 100 cm to 170 cm is capable of producing a mean peak power of about 230 W.
