To determine the necessary ballast weight for your Ubbink FRS60 flat roof solar panel installation, consult the ballast table provided in the Ubbink FRS60 manual. Follow these steps for accurate calculations: First, identify your installation height (h) in meters. Second, measure your solar panel dimensions to ensure they match the panel size specifications (Panel up to 1.7 x 1.0 m or Panel up to 1.75 x 1.15 m). Third, use the ballast table in the manual to find the appropriate values, based on your installation height and panel dimensions. Locate the values for "Centre" and "Bordure" (Center and Edge) corresponding to your panel size and height. These values represent the peak dynamic pressure (daN/m²) and the required ballast weight, inclusive of the module's weight (kg). For example, if your installation is between 4m and 8m high with panel dimensions up to 1.7 x 1.0 m, and you are ballasting at the center, the table indicates a 94 kg ballast weight. For any specific clarifications or questions about the table's values, reach out to Ubbink BV, Ubbink France, Ubbink NV, or Ubbink UK Ltd using the contact information in your manual.
