Znshine
Ground frame for 10 Znshine ZXMR-UPLDD132-610 (N-type, rectangular cells) panels (2×5)
2 rows of 5 panels, 6.10 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.

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 2 276, cantilever 824 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 ≈ 11.8 kN (with γ=1.5) vs ≈ 13.4 kN (concrete weight + soil friction, estimate) → 88%.Cherkasy: Foundation Ø350 × 1 100: 0.106 m³ of concrete per post. Wind uplift on the front post ≈ 10.3 kN (with γ=1.5) vs ≈ 11.4 kN (concrete weight + soil friction, estimate) → 91%.Chernihiv: Foundation Ø300 × 1 300: 0.092 m³ of concrete per post. Wind uplift on the front post ≈ 10.1 kN (with γ=1.5) vs ≈ 11.2 kN (concrete weight + soil friction, estimate) → 90%.

Yield
Yield: 1,139 kWh per 1 kW a year, ≈ 6,947 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.
