Solar plant: site data
Solar power plant in Nadtochiieve, Sumskyi Raion, Sumy Oblast
Nadtochiieve: 1,120 kWh per kWp a year, tilt 38° 1° east of south (PVGIS). 1.0% above the oblast median (1,110). #109 of 466 in the rayon, #377 of 1534 in the oblast.
Sumy, the rayon centre, is 9 km away. 156 m above sea level. 9 km away: Sumy, the nearest bigger centre, the same 1,117. Snow and wind from the nearest regional centre in the DBN — Суми, 9 km. 13.29 m between rows, pitch 17.06 m (latitude 50.9°).
