How good are solar panels in cold weather?

Solar panels harvest the power of the sun and convert it to
energy. On average, there is about 1 kilowatt of power for every
square meter of ground surface on a daily basis. The cold weather
does not affect the efficiency of the solar panel but the fact that
the sunlight is less direct in the winter months does reduce the
amount of energy each panel can convert. To increase the efficiency
of the panels no matter the time of year, make sure to keep them
clear of snow, ice, dirt, leaves, and anything else that can
interfere with the ability of the light to get inside the solar
panels. The lenses should be as clean as is practical. Think of
them as windows: the more cluttered the lenses are, the less energy
is able to get through to the photovoltaic cells that are the black
I hope this helps. If you have any other questions, feel free to let me know.
