What are the standard sizes of photovoltaic solar panels?

Standard sizes of photovoltaic solar panels

When a solar installation is going to be carried out, in particular on the roof, it is essential to know the exact dimensions of the photovoltaic panels. Below we explain how the size varies according to certain technical specifications.

In the solar panel market there are many models, with different sizes 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.

Other influencing factors are 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 angled using a rack on a flat roof, and you should also note that you should allow 2 cm between panels for clamps.

Solar panel measurements


Measurements of solar panels.

In general, the the size of the solar panels is average. They usually have the following measurements:

Polycrystalline and monocrystalline panels.

  • Maximum power between 230 W and 245 W
  • Height: 160-170cm.
  • Width: 90-100cm.
  • Thickness: 4-5cm.

Monocrystalline panels.

  • Maximum power between 190 W and 200 W).
  • Height: 130-140cm.
  • Width: 90-100cm.
  • Thickness: 4-5cm.

Thin-layer panels.

  • Maximum power between 77.5 W and 87.5 W.
  • Height: 120cm.
  • Width: 60cm.
  • Thickness: 0.6-0.7cm.

On average, 180-190W crystalline silicon panels are 10-15cm lower and narrower than 230-240W 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 sloping roof of 100cm to 170cm is capable of producing a average peak power of about 230 W.
