Huasun
Ground frame for 12 Huasun Himalaya G12 HS-210-B132DS720 (HJT) panels (2×6)
2 rows of 6 panels, 8.64 kW. The Solispec engine chose the profiles, the frame pitch and the footings for three snow and wind zones: Kherson has the lowest load of the regional centres, Cherkasy the median, Chernihiv the highest.

Checks and cautions
Member utilisation as the engine computes it. Cautions are checks that pass, but with a small margin.
- Rafter profileThe rafter is used above 80 %, or the frame's posts stand far apart: the structure passes, but the margin is small.Kherson: Rafter C-channel 60×40×2: span between posts 2 278, cantilever 825 mm → strength 88%.Chernihiv: Rafter Tube 60×60×2: span between posts 2 278, cantilever 825 mm → strength 84%.
- Embedment, mmThe footing resists wind uplift at above 80 % utilisation, or it is shallower than the frost depth. The soil resistance in the calculation is an estimate — check the soil on site.Kherson: Foundation Ø400 × 1 100: 0.138 m³ of concrete per post. Wind uplift on the front post ≈ 12.4 kN (with γ=1.5) vs ≈ 13.4 kN (concrete weight + soil friction, estimate) → 93%.Cherkasy: Foundation Ø350 × 1 100: 0.106 m³ of concrete per post. Wind uplift on the front post ≈ 10.8 kN (with γ=1.5) vs ≈ 11.4 kN (concrete weight + soil friction, estimate) → 95%.Chernihiv: Foundation Ø300 × 1 300: 0.092 m³ of concrete per post. Wind uplift on the front post ≈ 10.6 kN (with γ=1.5) vs ≈ 11.2 kN (concrete weight + soil friction, estimate) → 95%.
- Max. frame pitch, mmThe purlins between the frames are used above 80 % (strength or deflection): the structure passes, but the margin is small. A shorter frame pitch or a deeper purlin gives more margin.Chernihiv: Frame spacing 1 870 mm, 5 frames. Purlin C-channel 60×40×2: strength 84%, deflection 62% of L/200 (snow on panel 1 106 Pa).
