DAS Solar
Ground frame for 5 DAS Solar DAS-DH144NA-585 panels (1×5)
1 row of 5 panels, 2.93 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.

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 1 780 mm, 4 frames. Purlin C-channel 41×41×2.5: strength 84%, deflection 74% of L/200 (snow on panel 489 Pa).

Yield
Yield: 1,139 kWh per 1 kW a year, ≈ 3,331 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.
