The optimal tilt angles of solar panels for Isit, Sakha Republic, Russia (60,81º NL) were determined using satellite data of the total and diffuse average monthly daily solar irradiance for the horizontal surface. For a system with a preset tilt angle of solar panels (without tilt angle adjustment), the optimal tilt angle for 60º northern latitude was determined. It was revealed that the seasonal orientation of solar panels in Central Yakutia should be carried out in late March, early April and late August, early September due to the pronounced anticyclone weather in winter and spring.
