Do I have clean of snow PV-panels during winter time ??

During winter months (January, December), due to the short daytime and small amount of light reaching at a small angle to the PV panels, their percentage share in the annual energy production is in the range of 5-7%. Assuming that PV panels will not be obscured by the snow cover throughout their winter, their snow removal, omitting matters security is uneconomical.

Another dangerous situation occurs when only some of the panels are covered with snow, and the winter day is very sunny - then there is excessive heating of PV panels.
