Because of this, if only a few
modules are obstructed by snow, it will reduce the
performance of the entire circuit, which could magnify the
snowfall losses on a string. Also, because the modules are
intentionally oversized for a given inverter the fraction of
energy production in the wintertime is proportionally larger
than if the clipped power in the summer time was produced.
Because of this, snow losses will account for a larger
fraction of total produced energy.
