How to Calculate Square Meters of Photovoltaic Cells


Photovoltaic cells, also known as solar cells, are an essential component of solar panels which convert sunlight into electricity. When it comes to installing solar panels, it is important to understand the area that will be covered by the photovoltaic cells. In this article, we will discuss how to calculate the square meters of photovoltaic cells for your solar panel installation.

Calculating Square Meters

Determine the Size of the Solar Panels

The first step in calculating the square meters of photovoltaic cells is to determine the size of the solar panels that will be used. Solar panels come in standard sizes, typically around 1.6 square meters, but this can vary depending on the manufacturer and the specific model of the panel.

Calculate the Number of Solar Panels

Once you have determined the size of the solar panels, the next step is to calculate the number of panels that will be used in the installation. This can be done by measuring the area where the panels will be installed and dividing it by the size of each panel. For example, if the installation area is 80 square meters and the panels are 1.6 square meters each, you will need 50 panels to cover the entire area.

Account for Efficiency Loss

It is important to account for efficiency loss when calculating the square meters of photovoltaic cells. Solar panels are not 100% efficient, and factors such as shading, temperature, and panel orientation can affect their performance. As a general rule of thumb, it is recommended to add an extra 10-20% to the total area calculated to account for these losses.

Consider the Layout of the Panels

The layout of the panels can also affect the calculation of square meters. Depending on the orientation and tilt of the panels, the actual area covered by the photovoltaic cells may vary. It is important to take into consideration the layout of the panels when calculating the total area that will be covered.

Consult a Professional

Calculating the square meters of photovoltaic cells can be a complex process, especially when accounting for various factors that can affect the performance of the solar panels. It is always recommended to consult a professional solar installer who can provide accurate calculations and advice tailored to your specific installation.


Calculating the square meters of photovoltaic cells is an important step in planning a solar panel installation. By determining the size of the panels, accounting for efficiency loss, and considering the layout of the panels, you can ensure that your solar panels will effectively cover the desired area and produce the maximum amount of electricity. If you are unsure about the calculations, don’t hesitate to seek help from a professional to ensure a successful solar panel installation.
