The Solar Rooftop Potential Calculator estimates solar generation capacity based on technical data and efficiency factors. It uses 150 Wp/m² as the theoretical power output per square meter. Since not all space is usable, it applies a 70% factor to account for shading, roof tilt, and orientation. It’s ideal for planning solar panel installations in homes or businesses.

The simple formula used is 150 Wp × 70%, resulting in 105 Wp/m² of usable power. For example, a 50 m² roof would generate 5,250 Wp (5.25 kWp). The calculator doesn’t consider local variations like weather or obstructions, only area and general efficiency factors. It provides quick estimates but isn’t a substitute for expert analysis.

Use this tool in early solar project phases, such as calculating energy needs or comparing options. It helps determine if a roof has enough space to meet requirements. Remember that real results may vary depending on the region and specific conditions, such as tree shadows or roof structure.

Note: the 70% factor is a general average. Installations in high-solar-radiation regions may achieve higher efficiency. Conversely, shaded roofs will have lower real output. This calculator doesn’t replace technical measurements like inclinometers or 3D simulation software but serves as an initial basis for discussions with installers.
