Aiko

Ground frame for 30 Aiko Neostar 2P AIKO-A460-MAH54Mw panels (3×10)

3 rows of 10 panels, 13.80 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 Aiko Neostar 2P AIKO-A460-MAH54Mw panel and the 3 × 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.

  • 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 ≈ 12.1 kN (with γ=1.5) vs ≈ 13.4 kN (concrete weight + soil friction, estimate) → 90%.Cherkasy: Foundation Ø400 × 1 300: 0.163 m³ of concrete per post. Wind uplift on the front post ≈ 14.5 kN (with γ=1.5) vs ≈ 15.8 kN (concrete weight + soil friction, estimate) → 92%.Chernihiv: Foundation Ø350 × 1 500: 0.144 m³ of concrete per post. Wind uplift on the front post ≈ 14.2 kN (with γ=1.5) vs ≈ 15.5 kN (concrete weight + soil friction, estimate) → 92%.
  • 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 2 200 mm, 6 frames. Purlin C-channel 60×40×2: strength 81%, deflection 70% of L/200 (snow on panel 977 Pa).Chernihiv: Frame spacing 2 200 mm, 6 frames. Purlin C-channel 60×40×2: strength 87%, deflection 75% of L/200 (snow on panel 1 106 Pa).

The engine's estimate has 25 lines; the full list is in the builder. Prices are the typical market prices built into the Solispec engine, as of 06.10.2026; no margin, no VAT.

Yield

Yield: 1,139 kWh per 1 kW a year, ≈ 15,715 kWh a year in total (median zone, Cherkasy; tilt 30°, the optimum for the latitude is 35.3°).

A preliminary calculation; a design needs an engineer's check. Snow and wind per DBN V.1.2-2:2006 for the regional centre; profiles, footings and estimate by the Solispec engine 0.12.0.
