The Worldwide Solar Model 2 – 20° ZAM Steel Ballast Solar Mounting System is a compact, durable solution for single-panel ground-mounted and suitable flat-roof solar installations. Manufactured from high-strength ZAM steel, it combines straightforward assembly with a ballasted, non-penetrating design.
The zinc-aluminium-magnesium (ZAM) coating helps protect the steel against outdoor corrosion and has a C3 corrosion-resistance classification.
The fixed 20° tilt angle provides a compact installation profile. The system supports one framed solar panel weighing up to 38 kg with a frame thickness of 30–40 mm. The table below lists five panel dimensions and their corresponding ballast figures.
The stated design specifications are a 30 m/s wind speed and 1.0 kN/m² snow load.

The table shows the ballast weight per side of each solar panel for the five panel sizes. Each Model 2 mounting system has two ballast sides. For flat-roof installations, use the open-field / exposed figures as the minimum reference.
| Panel size (mm) | Open field / exposed Calculated weight |
Urban / residential Estimated |
Sheltered garden Estimated |
|---|---|---|---|
| 1762 × 1134 × 30 | 58.8 kg | 35.3 kg | 17.6 kg |
| 1953 × 1134 × 30 | 87 kg | 52.2 kg | 26.1 kg |
| 1954 × 1134 × 30 | 90 kg | 54 kg | 27 kg |
| 2063 × 1134 × 30 | 95 kg | 57 kg | 28.5 kg |
| 2333 × 1134 × 30 | 104 kg | 62.4 kg | 31.2 kg |
Design basis: 20° tilt, 30 m/s wind speed and 1.0 kN/m² snow load. The open-field figures are calculated for these conditions. The urban and sheltered-garden figures are estimates based on potentially reduced wind exposure. Ballast requirements vary with installation location, surrounding structures, local wind conditions and supporting surface.
Use solid, normal-weight concrete ballast stones, securely positioned in the designated ballast areas. Concrete ballast stones are not included and must be purchased separately.
Concrete ballast stones are not included. Ballast requirements can change with site conditions and installation location.
Before installation, ensure the supporting surface can carry the combined weight of the mounting system, solar panel and ballast. For flat roofs, use the open-field / exposed ballast figures as the minimum reference and check the roof's load capacity.
