Solar plant: site data
Solar power plant in Isai, Sambirskyi Raion, Lviv Oblast
Isai: 1,039 kWh per kWp a year, tilt 38° 4° east of south (PVGIS). 4.1% below the oblast median (1,084). #211 of 264 in the rayon, #1423 of 1532 in the oblast.
Sambir, the rayon centre, is 33 km away. 538 m above sea level — above 500 m the DBN snow and wind are higher. 33 km away: Drohobych, the nearest bigger centre, 1,073 — 3.2% less here. Snow and wind from the nearest regional centre in the DBN — Ужгород, 89 km. 11.66 m between rows, pitch 15.43 m (latitude 49.2°).
