Solar plant: site data
Solar power plant in Zapsillya, Sumskyi Raion, Sumy Oblast
Zapsillya: 1,116 kWh per kWp a year, tilt 38° 1° east of south (PVGIS). 0.6% above the oblast median (1,110). #166 of 466 in the rayon, #470 of 1534 in the oblast.
Sumy, the rayon centre, is 32 km away. 138 m above sea level. 32 km away: Sumy, the nearest bigger centre, the same 1,117. Snow and wind from the nearest regional centre in the DBN — Суми, 32 km. 13.42 m between rows, pitch 17.19 m (latitude 51.0°).
