The space required for a solar installation depends mainly on the desired output and the solar modules used. An average solar system requires around 6 to 10 square meters of roof space for 1 kWp (kilowatt peak). A typical system with 5 kWp, which is enough to cover the electricity needs of an average household, would require around 30 to 50 square meters.
The space requirements can also depend on the efficiency of the solar modules. Highly efficient modules can produce more solar power on less surface area, which reduces the amount of space required. The orientation of the roof and the angle of inclination also play a role, as an optimal orientation to the south and an angle of inclination between 30 and 40 degrees maximizes the efficiency of the modules.
If there is not enough space on the roof, there are also alternatives such as ground-mounted systems, façade installations or carports with solar panels. These options allow you to generate your own solar power even without a large roof. Overall, the available space should be carefully planned in order to exploit the maximum energy potential of the solar system and optimize its cost-effectiveness.
