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 depending on certain technical specifications.

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

The dimensions are generally 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. panel capacity.

Another influencing factor is the the power generated by each panel and the technology used (polycrystalline, thin film, amorphous, etc.).

There is only one reference that should allow row spacing if the panels are tilted using a support on a flat roof, and you should also note that this should allow 2 cm between the panels for the clamps.

In general, solar panels are average height. They typically have the following metrics:

  • 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, 180-190W crystalline silicon panels are 10-15cm lower and narrower that the 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 its rectangular area on a pitched roof of 100 cm to 170 cm is capable of producing a average peak power of approximately 230 W.
