Roof Surface

The roof area is one of the most important surfaces in photovoltaics for installing solar panels. Its orientation, inclination, and condition have a decisive impact on the efficiency of a photovoltaic system.

Orientation

The optimal orientation of a roof area for a photovoltaic system is usually towards the south. However, a deviation of up to 15 degrees to the east or west is still acceptable. A southern orientation ensures that the solar panels receive as much sunlight as possible throughout the day.

Inclination

The inclination of the roof area also influences the energy yields of a photovoltaic system. In Central Europe, an inclination of 30 to 35 degrees is considered optimal. This inclination provides a good compromise between winter and summer radiation. Flat roofs can also be equipped with photovoltaics, but special mounting systems are required.

Condition

The condition of the roof area also plays a role. A stable and tight roof is a prerequisite for the safe installation of solar panels. Additionally, the roof area should be sufficiently load-bearing to support the weight of the system. For older roofs, renovation may be necessary before installing a photovoltaic system.

Shading

Shading from trees, chimneys, or other parts of the building can significantly impair the performance of a photovoltaic system. Therefore, a thorough analysis of potential shading effects should be conducted before installing a photovoltaic system.

Conclusion

The roof area is a crucial factor in the success of a photovoltaic system. Optimal orientation, inclination, and condition maximize energy yields and ensure a long lifespan for the system.
