Solar plant: site data
Solar power plant in Obirky, Sarnenskyi Raion, Rivne Oblast
Obirky: 1,063 kWh per kWp a year, tilt 38° 5° east of south (PVGIS). 1.9% below the oblast median (1,084). #129 of 185 in the rayon, #938 of 1044 in the oblast.
Sarny, the rayon centre, is 4 km away. 145 m above sea level. 4 km away: Sarny, the nearest bigger centre, the same 1,063. Snow and wind from the nearest regional centre in the DBN — Рівне, 87 km. 13.80 m between rows, pitch 17.57 m (latitude 51.4°).
