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.Cherkasy: Frame spacing 2 040 mm, 4 frames. Purlin C-channel 60×40×2: strength 90%, deflection 72% of L/200 (snow on panel 977 Pa).Chernihiv: Frame spacing 2 040 mm, 4 frames. Purlin C-channel 60×40×2: strength 97%, deflection 77% of L/200 (snow on panel 1 106 Pa).

Yield
Yield: 1,139 kWh per 1 kW a year, ≈ 4,100 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.
