Section of the table from the Solispec engine (median zone — Cherkasy)

Luxor

Ground frame for 20 Luxor Eco Line Classic LX-450M/182-108+ GG (bifacial) panels (2×10)

2 rows of 10 panels, 9.00 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 Luxor Eco Line Classic LX-450M/182-108+ GG (bifacial) panel and the 2 × 10 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.

  • 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.Kherson: Frame spacing 2 710 mm, 5 frames. Purlin C-channel 60×40×2: strength 84%, deflection 90% of L/200 (snow on panel 489 Pa).Chernihiv: Frame spacing 2 200 mm, 6 frames. Purlin C-channel 60×40×2: strength 83%, deflection 71% of L/200 (snow on panel 1 106 Pa).
  • 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 ≈ 11.9 kN (with γ=1.5) vs ≈ 13.4 kN (concrete weight + soil friction, estimate) → 89%.Cherkasy: Foundation Ø300 × 1 100: 0.078 m³ of concrete per post. Wind uplift on the front post ≈ 8.5 kN (with γ=1.5) vs ≈ 9.5 kN (concrete weight + soil friction, estimate) → 90%.
