Solar plant: site data
Solar power plant in Velykyi Yar, Sumskyi Raion, Sumy Oblast
Velykyi Yar: 1,121 kWh per kWp a year, tilt 38° facing south (PVGIS). 1.0% above the oblast median (1,110). #107 of 466 in the rayon, #371 of 1534 in the oblast.
Sumy, the rayon centre, is 14 km away. 155 m above sea level. 14 km away: Sumy, the nearest bigger centre, the same 1,117. Snow and wind from the nearest regional centre in the DBN — Суми, 13 km. 13.21 m between rows, pitch 16.98 m (latitude 50.8°).
