How much space do solar panels require?
The space requirement of solar panels depends on several factors, such as the efficiency of the panels, the installation angle and the amount of available space. In this article, we will discuss these factors and give an overview of how much space solar panels require.
Efficiency of solar panels
The efficiency of solar panels directly affects how much electricity they can produce on a certain surface area. More efficient panels produce more electricity in a smaller area. The efficiency of solar panels on the market today usually ranges from 15% to 22%. For example, a solar panel with 20% efficiency produces more electricity than a panel with 15% efficiency for the same surface area.
Installation angle and orientation
The installation angle and orientation of the solar panels also affect their space requirements. The optimal installation angle and orientation maximizes the amount of sunlight that hits the panels, thus reducing the required surface area. In Finland, the optimal installation angle is usually around 35-45 degrees, and the panels should be oriented to the south to achieve the best possible yield.
Available space
The installation location of the solar panels also affects the space requirement. Ceiling installations are common, but panels can also be installed on the ground or other structures. In ceiling installations, the amount of space can be limited, so it is important to plan the installation carefully. When installing on the ground, there is usually more space, but in this case shading and other environmental factors must be taken into account.
Examples of space requirements
Generally speaking, one solar panel takes up about 1.6 square meters of space. For example, if you want to install a 5 kW photovoltaic system consisting of 20 panels, you need about 32 square meters of space. However, this is only a rough estimate and the actual space requirement may vary depending on the factors mentioned above.
Summary
The space requirement of solar panels depends on many factors, such as the efficiency of the panels, the installation angle and the amount of available space. In general, one solar panel takes up about 1.6 square meters of space, but the exact space requirement may vary. It is important to plan the installation of solar panels carefully in order to get the best possible return from the available space.
