Yield
Yield: 1,139 kWh per 1 kW a year, ≈ 7,060 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.
