Huasun

Ground frame for 16 Huasun Himalaya G12 HS-210-B132DS720 (HJT) panels (2×8)

2 rows of 8 panels, 11.52 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.

Open this frame in the builder

The builder opens with the Huasun Himalaya G12 HS-210-B132DS720 (HJT) panel and the 2 × 8 layout; site — Cherkasy. Change the site, the tilt or the profiles and the checks and estimate are recalculated.

Three snow and wind zones

The same table designed for three regional centres: with the lowest, the median and the highest combined snow and wind load under DBN V.1.2-2:2006. For another site, open the frame in the builder.

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 80%.Cherkasy: Rafter Tube 60×60×2: span between posts 2 278, cantilever 825 mm → strength 85%.Chernihiv: Rafter Tube 60×60×2: span between posts 2 278, cantilever 825 mm → strength 91%.
  • 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 Ø350 × 1 100: 0.106 m³ of concrete per post. Wind uplift on the front post ≈ 11.3 kN (with γ=1.5) vs ≈ 11.4 kN (concrete weight + soil friction, estimate) → 99%.Cherkasy: Foundation Ø400 × 1 100: 0.138 m³ of concrete per post. Wind uplift on the front post ≈ 11.7 kN (with γ=1.5) vs ≈ 13.4 kN (concrete weight + soil friction, estimate) → 88%.Chernihiv: Foundation Ø300 × 1 500: 0.106 m³ of concrete per post. Wind uplift on the front post ≈ 11.4 kN (with γ=1.5) vs ≈ 12.9 kN (concrete weight + soil friction, estimate) → 89%.
  • 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.Cherkasy: Frame spacing 2 020 mm, 6 frames. Purlin C-channel 60×40×2: strength 92%, deflection 73% of L/200 (snow on panel 977 Pa).Chernihiv: Frame spacing 2 020 mm, 6 frames. Purlin C-channel 60×40×2: strength 99%, deflection 78% of L/200 (snow on panel 1 106 Pa).
