Shadowing can have a significant impact on the performance of a solar panel system. The course of the sun must be carefully considered in the planning phase. The solar panels should not be in the shade at any time of the day or year. As part of the projected yield, the PREFA Product Technology department will assist you in designing the system to be as shade-free as possible.
What do you need to pay particular attention to as a result?
Shading of a solar panel system on the roof can be caused by various factors, such as surrounding buildings or trees, chimneys, ventilation pipes, antennas, as well as seasonal changes in the
sun’s position and weather conditions such as snow or ice.
In addition to the solar survey form, use drawings, sketches and pictures to record possible roof structures, antennas, chimneys, vents or overhead lines. These are then taken into account separately and included in the design.
